Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases.Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma,resulting ofpatient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma.We report a case of giant basal cell carcinoma metastaticin lung occurringin a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy.Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy.

Isolated peritoneal metastases of lung adenocarcinoma are very rare, even exceptional, occurringmost often in the context of a multi-metastatic disease. This report presents a rare clinical case of isolated peritoneal metastasis from lung adenocarcinoma. We report a 56-year-old malewho was monitored for lungadenocarcinoma whose evolution has been marked by an isolated metastatic recurrence in the peritoneum objectified by an abdominal-pelvic computed tomography (CT) and confirmed by a laparoscopy with abiopsy of the peritoneal nodules. The patient had received palliativechemotherapy with gemcitabine, cisplatin and bevacizumab. The evolution was marked by a progressive deterioration of the general condition and death two months after the third treatment cycle. Peritoneal carcinomatosis from lung adenocarcinoma is a very rare event, and is often associated with a poor prognosis.

Introduction: In lung adenocarcinoma, the frequency of EGFR and KRAS mutations is ethnicity dependent with different proportion in white Caucasians and in Asians. The prevalence of these mutations among North Africans patients is unknown. The objective of this study was to report the frequency and spectrum of EGFR and KRAS mutations in a group of Moroccan lung adenocarcinoma patients. Methods: Tumor specimens from 137 Moroccan patients with lung adenocarcinoma were selected to determine frequency and spectrum of EGFR and KRAS mutations. Mutation detection techniques were polymerase chain reaction amplification and DNA sequencing. Results: The overall frequency of the EGFR mutation was 21%. Mutations were mainly detected in the exon 19 (69%), followed by exon 21 (21%) and exon 20 (7%), whereas mutations in the exon 18 were rare (3%). EGFR mutation rate was significantly higher in women and in never smokers. The overall frequency of the KRAS mutations was 9%. In the population with KRAS mutations, there was a trend towards more male and more smokers compared to patients with wild type KRAS. Conclusion: This is the first study to date examining the frequency and spectrum of EGFR and KRAS mutations in lung adenocarcinomas in North African and Arab populations. Some one fifth of lung adenocarcinoma tumors in Moroccan patients harbor EGFR mutations. This mutation frequency is higher than that found in whites but lower than in Asian population. KRAS mutation frequency in Moroccan patients was lower than white Caucasian population and comparable with the frequency observed in East-Asian population. Further studies, in larger numbers of patients, are needed to confirm these findings. [ABSTRACT FROM AUTHOR]

Background: Mutations in the epidermal growth factor receptor ( EGFR ) gene are commonly observed in non-small cell lung cancer (NSCLC), particularly in adenocarcinoma histology. The frequency of EGFR mutations is ethnicity-dependent, with a higher proportion reported in Asian populations than Caucasian populations. There is a lack of data on these mutations in north Africa., Methods: Tumor specimens from Moroccan patients with NSCLC were collected from five pathology laboratories between November 2010 and December 2017 to determine frequency and types of EGFR mutations. Tumors were tested in a reference center for EGFR by polymerase chain reaction and sequencing of exons 18, 19, 20, and 21., Results: A total of 334 patients were enrolled: 242 (72.5%) males and 92 females (27.5%). A total of 56.9% had a history of smoking. EGFR testing of the 334 lung adenocarcinoma samples demonstrated a wild-type EGFR in 261 (78.1%) and mutated EGFR in 73 (21.9%). Mutations were mainly detected in the exon 19 deletion (65.8%), followed by exon 21 L858 (17.8%) and other exon 21 codon mutations (5.5%) and exon 18 (6.8%), whereas primary mutations of exon 20 were less frequent (4.1%). In patients with advanced NSCLC, the detection of EGFR mutation was independently associated with sex (41.3% female vs 14.5% male; p < 0.001) and smoking status (34.8% nonsmokers vs 12.9% active smokers; p < 0.001). The mean age was significantly different between the two groups ( p = 0.041)., Conclusion: Our findings confirm the genetic heterogeneity of NSCLC worldwide, reporting frequency of EGFR mutations in Moroccan patients with NSCLC between those of Asian and Caucasian populations.

Background: Epidermal growth factor receptor (EGFR) mutations are a heterogeneous group of genetic alterations mainly identified in lung adenocarcinoma (AC). They occur in exon 18 to 20 of the EGFR gene. Common EGFR mutations are deletions in exon 19 and substitutions in exon 21, while mutations in exon 18 and exon 20 are rare. Their response to tyrosine kinase inhibitors (TKI) is different, common EGFR mutations are more sensitive to TKI with better response rate and survival, whereas rare EGFR mutations are TKI resistant with poor prognosis and clinical outcomes. The objective of the present study was to report the frequency and characteristics of rare EGFR mutations in a group of Moroccan patients with lung AC harboring a positive EGFR mutation., Patients and Methods: All cases of Moroccan patients with lung AC harboring mutated EGFR were collected from 334 EGFR test requested. Common EGFR mutations were defined as deletions in exon 19 and substitutions in exon 21 while mutation in exons 18 and 20 were qualified as rare EGFR mutations. Patients' characteristics were reported and compared between the two groups of common and rare EGFR mutations., Results: EGFR mutations were positive in 73/334 of all requested tests. Common EGFR mutations accounted 89% (65/73). Rare EGFR mutations were present in 8 cases (11%). Rare EGFR mutations were composed of 62.5% exon 18 mutations (5/8) and 37.5% exon 20 mutation (3/8). The frequency of regular smokers in patients with tumors expressing rare EGFR mutations was significantly higher than that found in patients with tumors having common EGFR mutations (p=0.013)., Discussion: The frequency found in the present study was consistent with the literature data. However, we found that rare EGFR mutations occurred mostly in exon 18 rather than exon 20, findings that are discordant with the available literature. Thus, we could suggest that Moroccan patients with rare EGFR mutations would benefit more from TKI treatment., Conclusion: Rare EGFR mutations are a heterogeneous subset of genetic alterations in lung AC. Their study deserves a real relevant interest. Some one tenth of lung AC tumors in Moroccan patients harbor a rare EGFR mutation. Further prospective studies are needed, in larger numbers of patients, to assess their specific characteristics and outcomes.

Background: Primary adenoid cystic carcinoma (ACC) of the breast is a rare subtype of invasive breast cancer. It has a particular interest because of its excellent prognosis conversely to other triple-negative breast cancers that are associated with poor prognosis. The place of chemotherapy and radiotherapy remains controversial and there is no consensus on optimal management of the ACC of the breast., Case Report: A 50-year-old woman, presented with a palpable right breast lump. Core biopsy of the lump revealed an adenoid cystic carcinoma. A lumpectomy with axillary lymph node dissection was performed and completed by a mastectomy because of the positive surgical margins. The histopathological examination revealed an adenoid cystic carcinoma, with negative expression of hormone receptors and human epidermal growth factor receptor 2 HER2 and with no lymph node involvement. The patient underwent adjuvant sequential chemotherapy with anthracycline and taxane followed by radiotherapy. We discuss diagnosis, prognostic, and treatment options for ACC of the breast in light of existing literature., Conclusion: Adenoid cystic carcinoma of the breast is a rare variant of triple negative breast cancer with excellent prognosis. Surgical treatment is the mainstay with no clear consensus for radiotherapy and chemotherapy.
