Background: Head and neck cancer (HNC) is one of the most common cancers worldwide and its incidence is reported to be increasing in resource-limited countries. There is a paucity of published data regarding head and neck cancers in Tanzania, and Bugando Medical Centre in particular. This study describes the clinicopathological profile of HNC in our local setting and highlights the challenges in the management of this disease., Methods: This was a retrospective study of histopathologically confirmed cases of head and neck cancers treated at Bugando Medical Center between January 2009 and December 2013., Results: A total of 346 patients (M:F = 2.1:1) were studied representing 9.5 % of all malignancies. The median age of patients was 42 years. Cigarette smoking (76.6 %) and heavy alcohol consumption (69.9 %) were the most frequently identified risk factors for head and neck cancer. The majority of patients (95.9 %) presented late with advanced stages. Twenty-five (7.2 %) patients were HIV positive with a median CD4+ count of 244 cells/μl. The oral cavity (37.3 %) was the most frequent anatomical site affected. The most common histopathological type was carcinomas (59.6 %) of which 75.7 % were squamous cell carcinoma. A total of 196 (56.6 %) patients underwent surgical procedures for HNC. Radiotherapy and chemotherapy was reported in 9.5 and 16.8 % of patients, respectively. Only 2 (0.6 %) patients received chemo-radiation therapy. The mortality rate was 24.4 %. The overall 5-year survival rate (5-YSR) was 20.6 %. The predictors of overall 5-YSR were age of patient at diagnosis, stage of disease, extent of lymph node involvement, HIV seropositivity and CD4+ count <200 cells/μl (P < 0.001). Local recurrence was reported in 22 (23.4 %) patients and this was significantly associated with positive resection margins, stage of the tumor and presence of metastasis at diagnosis and non-adherence to adjuvant therapy (P < 0.001)., Conclusion: Head and neck cancers are not uncommon at Bugando Medical Centre and show a trend towards a relative young age at diagnosis and the majority of patients present late with advanced stage cancer. Therefore, public enlightenment, early diagnosis, and effective cost-effective treatment and follow-up are urgently needed to improve outcomes of these patients in our environment.

Background: Kaposi's Sarcoma is the most common sarcoma and second most prevalent cancer seen in Tanzania. Little is known about Kaposi's sarcoma in our setting as there is paucity of recent published data regarding this condition. This study describes the clinicopathological pattern and treatment outcome of Kaposi's sarcoma at Bugando Medical Centre, a tertiary care hospital in northwestern Tanzania., Methods: This was a prospective study of histologically confirmed Kaposi's sarcoma that was conducted at Bugando Medical Center between July 2004 and June 2014., Results: A total of 248 patients (M:F = 1.4:1) representing 2.4% of all malignancies during the study period were enrolled into the study. The median age at presentation was 36 years. Females were younger than males (p = 0.04). Out of 248 patients, 122 (49.2%) were HIV positive. Of these, 46 (37.7%) were males and 76 (62.3%) females. AIDS-related Kaposi's sarcoma were younger than HIV negative Kaposi's sarcoma patients (p = 0.011). Median duration of symptoms was 6 months. Kaposi's sarcoma was the AIDS defining disease in 82 (67.2%) patients while in the remaining 40 (32.8%) it was diagnosed between 1 and 14 months after the initial diagnosis of AIDS. The lower limb was most frequently involved site in 28.9% of patient. Females had more disseminated lesions compared with more localized lesions in the males (p = 0.001). The treatment modalities in this study included chemotherapy, radiotherapy, surgery and highly active antiretroviral therapy. Overall 126 (53.4%) patients had significant improvement in quality of life at the end of 1 year follow up. Treatment related complication and mortality rates were 25.8 and 24.2% respectively. Poor ACTG stage, CD4+ count <200 cells/µl, associated co-morbid illness, disseminated disease and poor adherent to chemotherapy were the significant independent factors associated with deaths (p < 0.001). Patient's follow-up was generally poor and data on long-term survivals were not available as more than two-thirds of patients were lost to follow up., Conclusion: Kaposi's sarcoma is the most common malignant vascular tumor and HIV/AIDS- related cancer in our region. There is an urgent need to develop health education programmes to enhance the understanding of this disease and how it spreads, particularly among the younger generation.

Background: Penile cancer is an uncommon malignancy in developed countries, but the incidence is as high as 10% to 20% of all male cancers in some developing countries. There is a paucity of published data on this subject in our setting. This study describes the clinicopathological presentation and treatment outcome of this condition in our environment, and highlights challenges associated with the care of these patients and proffers solutions for improved outcome., Methods: This was a retrospective study of histologically confirmed cases of penile cancer seen at Bugando Medical Centre between January 2004 and December 2013., Results: There were 236 penile cancer patients representing 2.2% of all male malignancies during the study period. The median age was 47 years with a modal age group of 41 to 50 years. Of the 236 patients, 147 (62.3%) had severe phimosis. The majority of patients (89.8%) were uncircumcised. A history of human papilloma virus (HPV) was reported in 12 (5.1%) cases. One hundred eighty-two (77.1%) patients reported history of cigarette smoking. Seven (6.7%) patients were human immunodeficiency virus (HIV) positive. The majority of the patients (68.6%) presented with Jackson's stages III and IV. Squamous cell carcinoma was the most common histopathological type (99.2%). Lymph node metastasis was recorded in 65.3% of cases, and it was significantly associated with the tumor size, histopathological subtype, histopathological grade, lympho-vascular invasion, positive resection margins, and urethral involvement (P < 0.001). Distant metastasis accounted for 4.2% of cases. The majority of patients (63.1%) underwent partial penectomy. Chemotherapy and radiotherapy were given in 14 (5.9%) and 12 (5.1%) patients, respectively. Complication and mortality rates were 22.0% and 4.2%, respectively. HIV positivity, histopathological stage and grade of the tumor, and presence of metastases at the time of diagnosis were the main predictors of death (P < 0.001). The median length of hospitalization was 14 days. Local recurrence was reported in 12 (5.3%) patients. Data on long-term survivals were not available as the majority of patients were lost to follow-up., Conclusions: Penile cancer is not rare in our environment. The majority of patients present late with advanced stage of the disease. Early detection of primary cancer at an early stage may improve the prognosis.

A one-day workshop on Burkitt lymphoma (BL) was held at the 9(th) African Organization for Research and Training in Cancer (AORTIC) conference in 2013 in Durban, South Africa. The workshop featured 15 plenary talks by delegates representing 13 institutions that either fund or implement research on BL targeting AORTIC delegates primarily interested in pediatric oncology. The main outcomes of the meeting were improved sharing of knowledge and experience about ongoing epidemiologic BL research, BL treatment in different settings, the role of cancer registries in cancer research, and opportunities for African scientists to publish in scientific journals. The idea of forming a consortium of BL to improve coordination, information sharing, accelerate discovery, dissemination, and translation of knowledge and to build capacity, while reducing redundant efforts was discussed. Here, we summarize the presentations and discussions from the workshop.

Background: Hepatocellular carcinoma is one of the most common cancers worldwide and its incidence is reported to be increasing in resource-limited countries. There is a paucity of published data regarding hepatocellular carcinoma in Tanzania, and the study area in particular. This study describes the clinicopathological profile of hepatocellular carcinoma in our local setting and highlights the challenging problems in the management of this disease., Methods: This was a retrospective study of histopathologically confirmed cases of hepatocellular carcinoma seen at Bugando Medical Center between March 2009 and February 2013., Results: A total of 142 patients (M: F = 2.2: 1) were studied representing 4.6% of all malignancies. The median age of patients was 45 years. Hepatitis B virus infection (66.2%) and heavy alcohol consumption (60.6%) were the most frequently identified risk factors for hepatocellular carcinoma. The majority of patients (88.0%) presented late with advanced stages. HBsAg was positive in 66.2% of the patients and Hepatitis C Virus antibody in 16.9%. Thirteen (9.2%) patients tested positive for HIV infection. Most patients (52.8%) had both right and left lobe involvement. The trabecular pattern (47.9%) was the most frequent histopathological type. None of patients had curative therapy because of the advanced nature of the disease. Coagulopathy (45.7%) was the most common complications. The overall mortality rate was 46.5% and it was significantly associated with comorbidity, HIV positivity, CD4+ count <200 cells/μl, high histological grade, advanced stage of the tumor, presence of distant metastases at the time of diagnosis, and associated complications (P < 0.001). The overall median duration of hospital stay was 14 days. The majority of patients (71.1%) were lost to follow-up at the end of the follow-up period., Conclusions: Hepatocellular carcinoma patients in this region are relatively young at diagnosis and the majority of them present late with an advanced stage and high rate of distant metastasis. Lack of awareness of the disease, poor accessibility to healthcare facilities, and lack of screening programs in this region may contribute to advanced disease at the time of diagnosis. There is a need for early detection, adequate treatment, and proper follow-up to improve treatment outcome.

Background: Breast cancer is the second leading cancer worldwide. In Tanzania, though it ranks as the second leading cancer in women after cervical cancer, hormonal receptor status is not carried out routinely in patients. Adjuvant hormonal therapy is given without prior knowledge of hormonal receptors status and patients can incur unnecessary costs and side effects. This study was performed to investigate the expression of hormonal receptors, epidermal growth factor receptors (HER-2) and proliferation index of the breast cancer by Ki-67 in a few selected patients with breast cancer at referral hospital in North-Western Tanzania. The study classified breast cancer subtypes based on hormonal receptors status and the expression of epidermal growth factor receptors., Results: A total of 52 cases of breast cancer were investigated. Patients' mean age at diagnosis was 49 years. The majority of the tumors was invasive ductal carcinoma 47 (90.4%) and 40 (76.9%) were of histological grade III. Thirty-eight (73.1%) of the patient had lymph node metastasis at the time of diagnosis and 36 (69.2%) were at clinical stage III. Only 3 (5.8%) patients were in clinical stage I. There was a tendency of a low level of expression of the receptors, whereby Estrogen Receptor (ER) positive tumors were 17 (32.7%), progesterone receptor (PR) positive tumors were 22 (42.3%), and HER-2 positive tumors were 12 (23.1%). Triple negative tumors constituted 20 (38.4%) of the patients. Most of the tumors (75%) showed high proliferation by Ki-67. Lymph node metastasis was more common in Triple Negative and HER enriched tumors., Conclusion: This study showed a tendency for a low level of expression of hormonal receptors. There was a significant proportion of Triple Negative breast cancers. Routine testing for hormonal receptors in breast cancer is recommended before the initiation of adjuvant hormonal therapy.

Introduction: Cancer of the cervix rank the second most common cause of cancer related deaths among women in Sub-Saharan Africa. It is estimated that 529, 409 new cases are diagnosed annually with a mortality rate approaching 274,883 per year. Cervical Intraepithelial Neoplasia (CIN) precedes almost all cervical cancers. The incidence rate of CIN among HIV infected women is five times higher as compared to the rate in HIV negative women. The screening for cervical dysplasia and an appropriate management in women with CIN are effective methods for preventing cervical cancer. This study was done to determine the prevalence and predictors of CIN among a HIV infected women attending Care and Treatment centre (CTC) at Bugando Medical Centre (BMC)., Methods: A cross sectional survey was undertaken among HIV infected women aged 18 years and above attending at BMC CTC clinic between February and March 2013. Visual Inspection with Acetic acid (VIA) was used as the screening method for detection of CIN. Socio-demographic, reproductive and clinical information was obtained from participants and the blood was collected for CD4 lymphocyte count. Cervical punch biopsy for histological examination was performed for those who had VIA positive test. Data were entered and analyzed using STATA Version 12.0 soft ware., Results: A total number of 95 (26.8%) participants had positive VIA test among three hundred and fifty-five (355) HIV infected women. Histology results showed; 4(4.2%) were normal, 26 (27.4%) had an inflammatory lesion, 58(61.1%) had CIN and 7(7.3%) had invasive cervical cancer. CIN was found to be associated with a history of multiple sexual partners (P<0.001), a history of genital warts (P<0.001), and a history of STI (P = 0.010)., Conclusion: The Cervical Intraepithelial Neoplasia is a problem among HIV infected women. A history of multiple sexual partners, a history of genital warts, a history STI and a low baseline CD4 T lymphocyte were significant predictors for CIN. Screening for Cervical Intraepithelial Neoplasia is recommended for all women with HIV.

Molecular methods are important tools for diagnosis and monitoring of many lymphoproliferative disorders. The reliability of lymphoma diagnoses is strikingly different between developed and developing countries, partly due to lack of access to these advanced molecular analyses. To overcome these problems, we propose a new application of dried blood spots (DBS) for detecting clonal B-cell populations in peripheral blood (PB). We ensured that the DBS contained sufficient lymphocytes to perform a PCR-based clonality assay without producing false positives. Using the Namalwa B-cell line, we established that the assay is sensitive enough to detect 200 clonal cells in the analyzed sample. Very similar clonal results were obtained between DNA from DBS and fresh whole blood from patients with B-cell chronic lymphocytic leukemia. B-cell clonality can also be detected in DBS from African children with EBV-associated diseases. This is the first study demonstrating that clonality testing can be performed on DBS samples, thus improving the diagnostic and monitoring options for lymphoproliferative diseases in resource-limited settings., (Copyright © 2013 Elsevier Ltd.

The triple assessment in the pre-operative evaluation of breast cancer has been practiced in some hospitals in Tanzania. However, its validity and reliability has not been evaluated in any hospital in the country including the study area. This cross-sectional study was conducted at Bugando Medical Centre in northwestern Tanzania to determine the validity, reliability and applicability of triple assessment as an alternative to conventional open biopsy in the pre-operative diagnosis of breast cancer. A total of 212 female patients aged 35 years and above were studied. All patients underwent clinical evaluation, mammography and fine needle aspiration cytology. Histopathology was done to confirm the diagnosis. One hundred and twenty (56.6%) patients with a median age of 36 years had benign lesions and the remaining ninety-two (43.4%) with a median age of 47 years had breast cancer (P = 0.002). With triple assessment, 92 patients were diagnostic for malignancy and 120 benign, respectively confirmed by histopathology. The Sensitivity, Specificity, Positive Predictive Value, Negative Predictive Value and Accuracy were 100.0%. There were no false positive or false negative results. The Kappa statistic for the combination was 1.0 implying excellent agreement with histopathology. The majority of patients (59.9%) underwent triple assessment on the same day with results being available to the patient within 24 to 72 hours. The triple assessment is an accurate and quick method for the evaluation of breast cancer and can be applied as a safe alternative for open biopsy when it is concordant.

Purpose: The increasing use of breast-conserving surgery makes it essential to identify biofunctional profiles responsible for the progression of in situ to invasive carcinomas to facilitate the detection of lesions that are most likely to relapse or progress and, thus, to be able to offer patients tailored treatment options. Our objective was to analyse and compare biofunctional profiles in ductal carcinomas in situ (DCIS) and invasive ductal carcinomas (IDC). We also aimed to identify markers in tumor and normal surrounding tissues that may be predictive of locoregional recurrence in patients with DCIS., Methods: Biofunctional parameters including mitotic activity, estrogen receptor, progesterone receptor, microvessel density (MVD), c-kit and p27 expression were evaluated in 829 in situ and invasive carcinomas. The impact of the biomarker profiles of DCIS, IDC and normal surrounding tissues on loco-regional recurrence was analyzed., Results: A progressive increase in cell proliferation and a concomitant decrease in steroid hormone receptor-positive lesions was observed during the transition from in situ to invasive carcinomas, as also within each subgroup as grade increased. Conversely, p27 expression and MVD dramatically decreased during the transition from in situ to invasive carcinomas. Finally, we found that a low c-kit expression was indicative of IDC relapse., Conclusions: Cell proliferation, hormonal and differentiation characteristics differed in DCIS with respect to IDC, and the main variation in the transition between the two histologic lesions was the decrease in p27 expression and MVD.

Background: Colorectal cancer is one of the most common cancers worldwide and its incidence is reported to be increasing in resource-limited countries, probably due to the acquisition of a western lifestyle. However, information regarding colorectal cancer in Tanzania and the study area in particular is limited. This study was conducted in our local setting to describe the clinicopathological pattern of colorectal cancer and highlight the challenging problem in the management of this disease., Methods: This was a retrospective study of histologically confirmed cases of colorectal cancer seen at Bugando Medical Center between July 2006 and June 2011. Data were retrieved from patients' files and analyzed using SPSS computer software version 17.0., Results: A total of 332 colorectal cancer patients were enrolled in the study, representing 4.7% of all malignancies. Males outnumbered females by a ratio of 1.6:1. The median age of patients at presentation was 46 years. The majority of patients (96.7%) presented late with advanced stages. Lymph node and distant metastasis at the time of diagnosis was recorded in 30.4% and 24.7% of cases, respectively. The rectosigmoid region was the most frequent anatomical site (54.8%) involved and adenocarcinoma (98.8%) was the most common histopathological type. The majority of adenocarcinomas (56.4%) were moderately differentiated. Mucinous and signet ring carcinomas accounted for 38 (11.6%)and 15 (4.6%) patients, respectively. Three hundred and twenty-six (98.2%) patients underwent surgical procedures for colorectal cancer. Only 54 out of 321 (16.8%) patients received adjuvant treatment. Postoperative complication and mortality rates were 26.2% and 10.5%, respectively. The overall median duration of hospital stay was 12 days. Only nine out of 297 survivors (3.0%) were available for follow-up at the end of 5 years. Cancer recurrence was reported in 56 of 297 survivors (18.9%). Data on long-term survival were not available as the majority of patients were lost to follow-up., Conclusions: Colorectal cancer is not uncommon in our environment and shows a trend towards a relative young age at diagnosis and the majority of patients present late with advanced stage. There is a need for screening of high-risk populations, early diagnosis and effective cost-effective treatment and follow-up to improve outcome of these patients.

Introduction: Burkitt lymphoma (BL) is endemic in parts of Tanzania, but there is scant country or region level data about burden and trends of BL in Tanzania over the past three decades. Here, we update baseline epidemiology of BL in northern Tanzania using recent data., Procedure: Data for childhood BL diagnosed at six hospitals in Mara and Mwanza regions in northern Tanzania during 2000-2009 were compiled. Age, sex, and regional patterns were analyzed. Crude incidence rates of BL were calculated by sex, anatomic site, geographical region, and calendar year., Results: Among 944 cases, 549 (58%) were male (male/female case ratio 1.4:1). Among those with known anatomic site (92%), facial only tumors represented a large proportion of tumors in boys than girls (50% vs. 36%, P < 0.002). Tumors occurred at a younger mean age in boys than girls (6.8 years vs. 7.6 years, P < 0.01). Crude BL incidence was 4.2 per 100,000, but varied by region (3.0 in Mwanza vs. 6.8 in Mara, P = 0.01), by district (1.4-22), by gender (5.0 in boys vs. 4.0 in girls), and by age group (2.0 in 0-4, 7.8 in 5-9, and 3.1 in 10-15 years). BL incidence peaked in 2001 and decreased gradually thereafter., Conclusions: Our results indicate that male sex, young age, and geographical characteristics are risk factors for BL in Tanzania. BL incidence declined with calendar year, but the significance of this finding is uncertain. Well-designed epidemiological studies of BL in Tanzania may shed light on environmental characteristics underlying these patterns., (Copyright © 2012 Wiley Periodicals, Inc.)

Breast cancer, although reported to be the commonest female malignancy worldwide has not been extensively studied in north-western Tanzania. The aim of this retrospective review was to describe in our setting, the stage at diagnosis, clinicopathological and treatment patterns among patients with breast cancer. Data were analyzed using SPSS software system. A total of 384 patients were studied. The median age was 45 years (range 21 to 78 years). The male to female ratio was 1: 46.8. Most of the patients were premenopausal (63.8%) and presented late with advanced breast cancer disease. Majority of patients (63.0%) presented with stage III disease. Lymph node and distant metastasis at the time of diagnosis was reported in 70.8% and 21.4% of patients, respectively. Invasive ductal carcinoma (91.7%) was the most frequent histopathological type and most patients (63.8%) had poorly differentiated tumour. Patients with tumour size greater than 6cm had significantly high rate of lymph node metastasis (P=0.001) and presence of necrosis within the tumour (P=0.012) compared to patients with tumour size less than 6cm in diameter. Patients younger than 45 years had significantly high rate of lymph node metastasis compared to the patients above this age (P=0.0 11). Mastectomy was the main modality of treatment that was used in 99.5% of the patients. Adjuvant chemotherapy and radiotherapy was reported in 44.8% and 11.7% of patients, respectively. Hormonal therapy (tamoxifen) was given postoperatively to all patients. The overall five-year survival rate was 21.8%. The age of patient at diagnosis, stage of disease, extent of lymph node involvement and histological grade were found to be independent predictors of overall survival rate (P<0.001). Local recurrence was 17.7% and it was significantly related to the stage of disease (P=0.003) and non-adherent to adjuvant therapy (P=0.021). Breast cancer patients in this region are relatively young premenopausal women and mostly present late with advanced stage and high rate of lymph node metastasis. There is need to improve public enlightenment of breast cancer and set up screening centres to encourage early presentations.

Marjolin's ulcer is a rare but well documented cutaneous malignancy that arises in a scar or chronic ulcer, and is characterized by an aggressive course. The latent period from the injury to the appearance of cancer has been reported to be 25-40 years. Early occurring Marjolin's ulcer has rarely been described in the literature and its development in a penile human bite scar is still rare. We report a rare case of a 33 year-old patient who presented with an early appearance of Marjolin's ulcer developing in a penile human bite scar. On histological examination it was found to be poorly differentiated squamous cell carcinoma. He was managed by total penile amputation. Five months after surgery, the patient presented to our surgical outpatient clinic with inguinal lymph node metastases and distant metastases to the lung, liver and bones. However, the patient died shortly after admission. This report highlights the possibility of early appearance of Marjolin's ulcer arising from a chronic ulcer or healed scar in an unusual sites such as the penis. It is therefore recommended that all chronic ulcers should be thoroughly investigated at presentation, to avoid labelling malignancies 'chronic ulcers', leading to delay in appropriate treatment. Early recognition and aggressive treatment of Marjolin's ulcers and close follow-up are urgently needed to improve outcomes in our environment.

Background: Skin cancers are a major risk associated with albinism and are thought to be a major cause of death in African albinos. The challenges associated with the care of these patients are numerous and need to be addressed. The aim of this study was to outline the pattern and treatment outcome of skin cancers among albinos treated at our centre and to highlight challenges associated with the care of these patients and proffer solutions for improved outcome., Methods: This was a retrospective study of all albinos with a histopathological diagnosis of skin cancer seen at Bugando Medical Centre from March 2001 to February 2010. Data collected were analyzed using descriptive statistics., Results: A total of 64 patients were studied. The male to female ratio was 1.5:1. The median age of patients was 30 years. The median duration of illness at presentation was 24 months. The commonest reason for late presentation was financial problem. Head and the neck was the most frequent site afflicted in 46(71.8%) patients. Squamous cell carcinoma was the most common histopathological type in 75% of cases. Surgical operation was the commonest modality of treatment in 60 (93.8%) patients. Radiotherapy was given in 24(37.5%) patients. Twenty-seven (42.2%) of the patients did not complete their treatment due to lack of funds. Local recurrence following surgical treatment was recorded in 6 (30.0%) patients. Only thirty-seven (61.7%) patients were available for follow-up at 6-12 months and the remaining patients were lost to follow-up., Conclusions: Skin cancers are the most common cancers among albinos in our environment. Albinism and exposure to ultraviolet light appears to be the most important risk factor in the development of these cancers. Late presentation and failure to complete treatment due to financial difficulties and lack of radiotherapy services at our centre are major challenges in the care of these patients. Early institution of preventive measures, early presentation and treatment, and follow-up should be encouraged in this population for better outcome.

Dermatological malignancies are among the most common form of cancers and the global incidence has been increasing at an alarming rate. A retrospective study was conducted to determine the prevalence, histopathological pattern, anatomical distribution and treatment outcome of dermatological malignancies at Bugando Medical Centre in North-western Tanzania. Data were collected from patients' files kept in the Medical record department; the surgical wards, operating theatre and histopathology laboratory and analyzed using Statistical package for social sciences system. A total of 154 patients with a histopathological diagnosis of dermatological malignancy were studied. Generally, males outnumbered females by a ratio of 1.4:1. The majority of patients were in the 5th and 6th decades of life. Malignant melanoma was the most common dermatological malignancy (67.5%) followed by Kaposi's sarcoma (10.4%), Squamous cell carcinoma (8.4%) and Basal cell carcinoma (7.8%). The lower limbs were the most frequent site accounting for 55.8%. Wide local excision was the most common surgical procedure performed in 79.2% of cases. Post-operative wound infection was the most common complication in 58.3% of patients. Mortality rate was 3.8%. Dermatological malignancies are more prevalent in our setting. A high index of suspicion is needed to avoid labelling malignancies "chronic ulcers" and all suspected lesions should be biopsed.

In this report we describe the case of a 22-year-old female who presented to our hospital with a 2 week history of chest tightness and easy fatigability. Examination and chest ultrasound revealed a massive pericardial effusion with evidence of tamponade. A rapid test for HIV was positive. Diagnostic and therapeutic pericardiocentesis was performed with good clinical response and revealed serosanguinous, exudative fluid. According to national guidelines, the patient was empirically treated for tuberculous pericarditis. Recurrence of the pericardial effusion occurred after 2 weeks and the cardiothoracic surgeons were consulted. Several days later, the patient was taken to the operating theatre and a pericardial window was performed with resultant drainage of over 5 litres of pericardial fluid. Visualization of the pericardium revealed a purple, multinodular mass of about 4x6cm on the epicardium consistent with Kaposi's sarcoma of the pericardium. Five litres of blood stained fluid were drained. Anti-tuberculosis treatment was stopped and the patient was referred to the oncology unit. The patient was started on antiretroviral treatment and Vincristine chemotherapy and the pericardial effusion resolved completely after 6 cycles of chemotherapy. Kaposi sarcoma should be considered as differential diagnosis in HIV/AIDS patient presenting with massive pericardial effusion.
