Becker’s naevus (BN) presents as a unilateral, hyperpigmented patch with hypertrichosis over the upper trunk/proximal upper extremity. Usually, block-like/geographical pattern is seen; however, linear forms have also been reported. A 21-year-old man presented to us with a history of hyperpigmented, well to ill-defined discrete-to-coalescent plaques with brownish macules scattered at the periphery, over posteromedial aspect along Blaschko’s lines, extending from the buttock to the ankle of the right lower limb. No associated hypertrichosis/focal defects were seen. On dermoscopy (10×, DermLite DL4W, Dana Point, California) pigment network, scaling with perifollicular accentuation, perifollicular hypopigmentation, and uniform brown dots/globules/lines were seen. A skin biopsy revealed acanthosis and focal papillomatosis with increased pigment in the basal layer; pigment incontinence and melanophages were seen in the dermis. To the best of our knowledge, only one such case has been reported with Blaschko-linear BN over the lower limb. We present here an uncommon case of Blaschko-linear BN over the lower limb with dermoscopy and a concise literature review of BN over the lower limb.

A 3-month-old boy presented with an intranasal polypoidal mass protruding out of the nostril which was present since birth and growing slowly. The mass was non-pulsatile and soft to firm in consistency. It did not increase in size on coughing, crying, or compression of the jugular vein. Magnetic resonance imaging and contrast-enhanced computed tomography (CT) revealed a lobulated well-circumscribed soft tissue mass in the left nasal cavity with no intracranial communication. Complete surgical excision of the mass was carried out via an intranasal endoscopic approach. Histopathological examination confirmed the diagnosis of intranasal glioma.

Background: Celiac Disease involves the small intestine patchily affecting more frequently the proximal small bowel but the histological changes have been observed till terminal ileum. Of late in addition to D2, the duodenal bulb (D1 region) biopsies have been found helpful in identifying a small group of patients with CD. Therefore, multiple site biopsies are recommended as histological changes are not uniform throughout small intestine. Methods: During this present 1.5 years prospective study, we evaluated 84 cases of suspected celiac disease with respect to the light microscopy (D1, D2, and D3 biopsy) and serology (anti tTg and or EMA). Histological examination was done according to Modified Marsh grading system. Results: Out of 84 cases with raised anti tTg, the segmental biopsies significantly increased the diagnostic accuracy from 39/44 cases (88.6%) to 43/44 cases (97.7%) and 44/44 cases (100%) when D2 alone, D1 + D2 and D1 + D2 + D3 biopsies were evaluated, respectively. Of the suspected cases of celiac disease patients (tTg > 10 ULN and associated weight loss, diarrhea), additional D3 biopsy increased the diagnostic yield by 2.1%, compared to D1, D2 region biopsy and 6.38% compared to standard D2 biopsy alone. Of the 28 cases (tTg > 10 times ULN + EMA positive and associated weight loss, diarrhea), the potential celiac disease (histologically Type 1/Normal) cases reduced from 28.5% (standard D2 region alone) to 21.4% and 17.8% when additional biopsies were taken from D1 region and D3 region, respectively, and additional D3 biopsy increased the diagnostic yield by 10.8% (compared to standard D2 biopsy alone) and 3.7% (compared to D1 and D2 biopsy). Conclusion: We believe multiple sites duodenal biopsies including D3 region biopsies might increase the diagnostic accuracy of adult celiac disease in addition to sensitive and specific serologic tests.

Background Primary extranodal lymphomas are less frequently encountered and difficult to diagnose in routine practice. The histopathological and immunohistochemical studies are essential in addition to clinical details to diagnose. The incidence is varied in different parts of India along with variation in histopathological spectrum. Methodology The clinical features and histopathological findings of patients diagnosed with primary extranodal lymphoma over 3-year period were retrieved from archives of pathology department and analyzed. Results During the 3-year study period, a total of 135 cases of non-Hodgkin lymphomas were evaluated, and of these, 41.4% (56/135) of cases presented with primary extranodal involvement. The mean age of primary extranodal lymphoma presentation was 61.3 ± 17.5 with M:F ratio of 1:1.1 Most common extranodal site involved was gastrointestinal tract 32.1%, 18/56 (small intestine [17.8%, 10 cases] and large intestine [8.9%, 5 cases]). Non-Hodgkin lymphomas of B cell type were the predominant subtype (48/56, 85.7%), while 8/56 (14.2%) cases were of T cell lineage. Of the B cell non-Hodgkin lymphoma diffuse, large B cell lymphoma was the predominant subtype constituting ~83.3% (40/48). Conclusion Primary extranodal lymphomas exhibit varied histomorphological and clinical presentation. The present study is first such analysis from Punjab that intends to compare with studies from other parts of India.

Echinococcosis is a common cause of pulmonary cavities. Aspergillus fumigatus, a saprophytic fungus, can colonise pulmonary cavities caused by tuberculosis, sarcoidosis, echinococcosis, bronchiectasis and neoplasms. Infection by Aspergillus is often seen in immunosuppressed cases. However, co-infection of Aspergillus with pulmonary echinococcosis is unexpected and very unusual, especially in an immunocompetent patient. We present the case of a 45-year-old immunocompetent male who came with non-resolving pneumonia and fever for 8 months and dyspnoea since 15 days accompanied by recurrent episodes of hemoptysis since 5 days. Chest X Ray and Computed Tomography scan showed a cystic lesion in the middle lobe of the right lung. Middle lobectomy with video-assisted thoracoscopic surgery was performed and histopathology revealed ectocyst of Hydatid cyst which was also colonised by septate fungal hyphae exhibiting acute angled branching, morphologically consistent with Aspergillus. Gomori Methanamine Silver and Periodic Acid Schiff stains highlighted the hyphae of Aspergillus as well as the lamellated membranes of ectocyst and an occasional scolex of Echinococcus. Sections from surrounding lung parenchyma also showed these fungal hyphae within an occasional dilated bronchus. Thus a diagnosis of dual infection of Aspergillosis and Pulmonary Echinococcosis was established. The possibility of dual infection by a saprophytic fungus must be kept in mind while dealing with a case of a cavitary lesion in long-standing and non-resolving pneumonia, even in an immunocompetent patient. Establishing the correct diagnosis of Aspergillosis with Echinococcosis is essential for proper and complete management.

Background: The incidence of coronary artery disease (CAD) has risen considerably in developing world due to industrialization, urbanisation and lifestyle changes, especially among Indians and South Asians. The onset of CAD has been seen to occur at an early age and the severity of the disease and mortality associated with CAD has also increased. The pathology of atherosclerosis needs to be re-evaluated to develop targeted therapy which can contain the disease process at the earliest stage. Aims and Objectives: Most of the morphological studies on atherosclerosis have been done on autopsy cases. In this study, we have analysed the morphological spectrum of atherosclerotic lesions in live patients. Materials and Methods: We retrospectively analysed the histopathology slides of 85 cases whose endarterectomy plaques were received in the Department of Pathology over a period of three and half years (January 2014 to June 2017) and classified the lesions according to Modified American Heart Association classification of atherosclerosis. Results: The average age of patients was 60 years and male to female ratio of 4.3:1. Left anterior descending artery was the commonest vessel involved (52.4%). Majority of the cases had fibrocalcific plaques,followed by fibrous cap atheroma and calcified nodules. Conclusion: Coronary artery plaques were found even in patients less than 40 years old. Aggressive lipid defense therapy needs to be the cornerstone of management of CAD.

Background and Objective: Xanthogranulomatous oophritis is an uncommon, non-neoplastic, chronic process in which the affected organ is destroyed by massive cellular infiltration of foamy histiocytes admixed with multinucleated giant cells, plasma cells, fibroblasts, neutrophils, and foci of necrosis. The etiology of this entity is unknown, but it shares histopathological findings similar to those of xanthogranulomatous change occurring in various organs, including the gallbladder and kidney.Case Report: The current case was a 20-year-old female presenting with a tubo-ovarian mass with suspicion of malignancy on clinicoradiological findings and final diagnosis of xanthogranulomatous oophritis established on histopathology.Conclusion: Clinically and radiologically, xanthogranulomatous oophritis mimics tumor of the ovary and fallopian tube, thereby making it an important entity. A vigilant histopathological evaluation is important to diagnose the disease.

Entamoeba histolytica has been rarely reported as superadded infection over carcinomatous growth on rectal brushings. We present a case of 68-year-old male who presented with abdominal pain and bleeding per rectum who was found to have an ulceroproliferative growth on sigmoidoscopy. Rectal brushings revealed coexistence of E. histolytica with malignant cells of adenocarcinoma. No organism was detected on biopsy of the tumor, which also showed adenocarcinoma, because of possible surface colonization of the tumor by Entamoeba. This case highlights the role of rectal brushings in detecting superadded infection in a case where both brushings and biopsy were performed. It is always important to report infection superadded on malignancies for optimum management of the patients.

Background & objective: Introduction: First detection of any solid tumour as metastatic deposits in bone marrow directs clinicians to start searching for the primary tumour. Detection of bone marrow metastasis determines the stage of the malignancy, prognosis, mode of treatment, chemotherapeutic response and follow-up in case of relapse. The aim of the current study was to analyse the clinico-haematological presentation and morphological pattern of infiltration of solid tumours detected first as metastatic deposits on bone marrow examination. Methods:Three-year retrospective analysis of MGG-stained bone marrow aspiration smears and touch imprints of the bone marrow biopsy and Hematoxylin and Eosin (H&E) stained histopathological sections of biopsies was performed at the Department of Pathology at a tertiary care institute (January 2014 to December 2016). The morphological pattern of metastatic deposits and haematological profiles of the patients were analysed. Exclusion criterion was the presence of hematolymphoid malignancies. Results: In 22 cases, bone marrow was the first site of detection of metastasis. The age of the patients ranged from 3 years and 10 months to 82 years, with equal gender predilection. Overall, 16 cases had cytopenias, 9 cases each had leucocytosis and leukoerythroblastic presentation. The metastasis was from Ewing’s sarcoma, prostate carcinoma, gastric adenocarcinoma invasive duct carcinoma breast, gallbladder carcinoma, lacrimal duct carcinoma and invasive papillary urothelial carcinoma. Conclusions: Bone marrow examination is a cheap and reliable investigation to detect metastasis in an unsuspecting case. Bilateral trephine biopsies are recommended to increase the efficacy of detecting bone marrow metastasis.

Background/AimsThe therapeutic goal for treating ulcerative colitis (UC) patients has shifted to achieving mucosal healing over the past few years. However, at present, limited data is available on the correlation between endoscopic findings and histological remission in patients with endoscopic mucosal healing.MethodsThis was a prospective observational study conducted over a period of 18 months (January 2014 to June 2015) at Dayanand Medical College and Hospital, Ludhiana, Punjab, India. Patients diagnosed with UC who had been in clinical remission (n=76) for at least 6 months were evaluated for endoscopic remission. Those in endoscopic remission (Mayo score ≤1; 46/76, 60.5%) were subjected to multiple biopsies from the rectosigmoid region and histological remission, which was then defined as grade 0/1 as per the Geboes criteria.ResultsOf the 46 patients in endoscopic remission (age, 18–73 years; male:female=1.5:1.0), majority had E1 (proctitis) disease (21/46, 45.6%) followed by E2 (left sided colitis) (18/46, 39.1%) and E3 disease (pancolitis) (7/46, 15.2%) at baseline. Histological remission was noted in 67.3% (31/46) of the patients, while 32.7% (15/46) still retained the histologically active disease in the form of infiltration of the lamina propria by eosinophils and neutrophils (13/15, 86.6%), cryptitis (14/15, 93.3%), and crypt abscesses (8/15, 53.3%). On follow-up, after 1 year, 87.1% (27/31) of the patients who had been in histological remission remained clinically asymptomatic, while 12.9% (4/31) had relapsed. Among the 15 histologically active patients, 46.6% (7/15) remained in clinical remission, while 53.3% (8/15) had relapsed.ConclusionsHistological remission, rather than endoscopic remission, predicts a sustained clinical remission and allows monitoring of therapy for the subsequent disease course in patients with UC.

Introduction: Nephrectomy is a common surgical procedure done for a variety of neoplastic and nonneoplastic diseases. This study has been taken up to analyze kidney diseases histopathologically and various lesions of the kidney and their subtypes and record the various lesions which have lead to partial nephrectomy, total nephrectomy, unilateral and bilateral nephrectomies. Aim: To study spectrum of diseases in nephrectomy specimens, histological sub typing of neoplastic conditions and evaluation of histopathological prognostic features like capsular invasion, vascular invasion and nuclear grade. Materials and Methods: This was an retrospective and prospective analysis done over the period of 4 years (2006-2009). A nephrectomy specimens received in the Department of Pathology Dayanand Medical College and Hospital, Ludhiana were analyzed with respect to gross and microscopic features. Results: Out of a total number of 155 cases, 82 were neoplastic, 73 were non-neoplastic males were 98 and females 57 with a M:F ratio 1.7:1. Out of the 82 neoplastic cases, Renal cell carcinoma (Clear cell type) was commonest (57 cases) followed by Transitional cell carcinoma (07 cases), Papillary RCC (03 cases), Oncocytoma (03 cases), Wilm’s tumour (02 cases), RCC with sarcomatoid change (02 cases), RCC unclassifiable (03 cases) and 01 case each of Chromophobe RCC, Multicystic RCC, Collecting duct carcinoma and small round cell tumour respectively. Of the 73 non-neoplastic cases, chronic pyelonephritis with hydronephrosis constituted 42 cases, emphysematous pyelonephritis (16 cases), xanthogranulomatous pyelonephritis (02 cases), acute or chronic pyelonephritis (09 cases), polycystic kidney (02 cases), cystic renal dysplasia and tuberculosis (01 case each). Conclusion: Radical nephrectomy is the common surgical procedure done for both neoplastic disorders as well as non neoplastic lesions. Detailed histopathological examination is necessary for diagnosis and the prognostication of the lesions.

Basal cell carcinoma (BCC) commonly affects the elderly and is mostly confined to the head and neck region. Only 10% of all cases occur on the trunk. We presented a case of bullous lesion on the abdomen in a young male, initially diagnosed by clinicians as a vascular nevus. Histopathological examination and immunohistochemistry (IHC) revealed it to be Nodular cystic variant of BCC. This rare variant of BCC morphologically resembles benign skin adnexal tumor of Eccrine syringofibroadenoma. Ber Ep4 positivity on IHC established the correct diagnosis. This case highlights that nodular cystic variant of BCC can be a diagnostic dilemma for clinicians and pathologists.

Aplastic anemia (AA) is nowadays considered to be a clonal disorder arising from a defective hematopoietic stem cell developing after a generalized insult to bone marrow. Immunosuppressive treatment (IST) of AA causes suppression of the target dominant population of haematopoietic cells allowing the defective non targeted clones to expand. This may give rise to acute leukemia. Cytogenetic studies for chromosomal aberrations such as trisomy and monosomy may help in detecting such conversions. We present a case of acquired AA in a 60-year-old male presenting with pancytopenia and hypoplastic marrow treated with antithymocyte globulin, converting into myelodysplastic syndrome and later on acute promyelocytic leukemia after being in remission for 4 years. The patient was found to have trisomy 8 on fluorescence in situ hybridization and karyotyping.

Mucormycosis is an opportunistic invasive fungal infection caused by Mucorales of class Zygomycetes. It is commonly seen in immunosuppressed cases. Gastrointestinal infection (GI) is very uncommon among adults and is diagnosed only on histopathological examination of biopsy or resection specimens. Due to non-specific clinical presentation, intestinal mucormycosis is diagnosed late. We report a series of six cases of intestinal mucormycosis in adults. Three years retrospective analysis of ileal and colonic resection specimens was performed in our tertiary care institute. All the cases had mucosal ulceration and necrosis on microscopic examination and one case also exhibited angioinvasion. Histopathology is the cornerstone of diagnosis and prompt management of invasive mucormycosis which may follow a rapid and fatal course in the absence of timely and optimum management. The clinicians need to keep the possibility of this vasculotropic fungus in mind in all cases presenting with abdominal symptoms.

Female Genital Tract (FGT) involvement with hematologic neoplasms is uncommon and the hematologic malignancies which involve the female genital organs are usually non-Hodgkin’s lymphoma. Involvement of the uterus and cervix with Acute Lymphoblastic Leukaemia (ALL) is extremely rare, and ovarian involvement is even rarer. We report the case of a young lady who presented with tubo-ovarian mass, excessive post-operative bleeding (post-total abdominal hystrerctomy and bilateral salpingo-oophorectomy) and was diagnosed to have ALL with blood and tissue involvement by histopathology and flow cytometry.

Splenic epidermoid cysts are rare non-parasitic true cysts affecting the spleen. We report a five-year-old child who presented with an abdominal lump associated with pain of 15 days. Ultrasonography of the abdomen showed a huge cystic lesion of obscure origin. At laprotomy a huge unilocular cyst involving upper part of spleen containing pultaceous fluid was seen and its removal necessitated splenectomy. Histopathological findings were consistent with splenic epidermoid cyst. Thus histopathology helped in elucidating the aetiology and diagnosis.

Background: Haematological abnormalities are common in acute febrile tropical illnesses. Malaria is a major health problem in tropics. In endemic areas especially in the post monsoon season, it is not practical to manually screen all peripheral blood films (PBF) for malarial parasite. Automated analysers offer rapid, sensitive and cost effective screening of all samples. Aim: The study was done to evaluate the usefulness of automated cell counters analysing their histograms, scatter-grams and the flaggings generated in malaria positive and negative cases. The comparison of other haematological parameters were also studied which could help to identify malaria parasite in peripheral blood smear. Materials and Methods: The blood samples were analysed using Beckman coulter LH-750. The abnormal scatter grams and additional peaks in WBC histograms were observed diligently & compared with normal controls. Haematological abnormalities were also evaluated. Statistical Analysis: Statistical analysis was done by using software Epi-Info version 7.1.4 freely available from CDC website. Fisher exact test was applied to calculate the p-value and value < 0.05 was considered as significant. Final identification of malarial parasite species was done independently by peripheral blood smear examination by two pathologists. Results: Of all the 200 cases evaluated abnormal scatter grams were observed in all the cases of malaria while abnormal WBC histogram peaks were noted in 96% cases demonstrating a peak at the threshold of the histogram. The difference between number of slides positive for abnormal WBC scatter gram and abnormal WBC histogram peaks were statistically highly significant (p=0.007). So abnormal WBC scatter gram can better give idea of malarial parasite presence. Of the haematological parameters thrombocytopenia (92% cases) emerged as the strongest predictor of malaria. Conclusion: It is recommended for haematopathologists to review the haematological data and the scatter plots on the analyser along with peripheral blood smear examination.

Ovarian-type surface epithelial carcinomas of testis and paratestis are very rare. These tumors develop from mesothelial inclusions or abnormalities in the development of coelomic epithelium. The diagnosis of these lesions can be difficult, both clinically and radiologically, as morphological, immunohistochemical and ultrastructural features overlap with serous tumors arising in the female genital tract. The pathologist should be aware of the histopathological features and immunostains which help in reaching definite diagnosis. To the best of our knowledge only one such case has been reported in Indian literature. We hereby report a case of young male with this unusual lesion diagnosed on histopathology.

Hemangioendotheliomas are rare vascular tumors that can arise from soft tissue or bone. The former comprises hemangioma, epithelioidhemangioma, hemangiomatosis and massiveosteolysis or Gorham′s disease (which mimics malignantneoplasm due to aggressive osteolytic destruction). The rarer malignant counterparts are epithelioidhemangioendothelioma, hemangioendothelioma and angiosarcoma in increasing order of malignancy. The diagnosis of these lesions is difficult both clinically and radiologically. Hereby we report an unusual case which was mistaken for metastasis and was diagnosed with the help of histopathology.

Coccidioidomycosis is a fungal disease found only in the Western Hemisphere. In recent years, the incidence of the disease has increased in California and Arizona, which may be partially due to the rapid immigration of previously unexposed persons from states outside the endemic areas. The disease in the nonendemic areas is usually imported. Determining a history of exposure is critical for performing the diagnosis of coccidioidomycosis in these cases. Histopathological examination is the key to the diagnosis when fungal culture and molecular studies are not available. We hereby report an imported case of cutaneous coccidioidomycosis, which to the best of our knowledge is the first case report from North India.
