Metastatic giant basal cell carcinoma: a case report.

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 of patient's negligence.

Peritoneal carcinomatosis, an unusual and only site of metastasis from lung adenocarcinoma.

Isolated peritoneal metastases of lung adenocarcinoma are very rare, even exceptional, occurring most 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 male who was monitored for lung adenocarcinoma 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.

[Granulosa cell tumors of the ovary].

Ovarian granulosa cell tumors (TGO) are rare neoplasms. They arise from sex cord stromal cells of the ovaries. They are characterized by their slow natural history, and their tendency to relapse long time after the initial diagnosis.

Malignant peripheral nerve sheath tumor of the small bowel: an unusual presentation with fatal outcome.

Malignant peripheral nerve sheath tumor of the small bowel is an extremely rare disease. Histologic distinction from other types of soft tissue sarcoma especially fibrosarcoma and leiomyosarcoma requires electron microscopy. Complete surgery remains the only curative treatment.

Primary immature teratoma of the uterus relapsing as malignant neuroepithelioma: case report and review of the literature.

Background. Although some mature cases of teratomas have recently been described in the cervix, they are not commonly found in the uterus, especially in immature forms. An immature uterine teratoma relapsing after surgery as malignant neuroepithelioma has never been reported in the literature.

Null phenotype non-Hodgkin lymphoma presenting as a large chest wall mass: case report.

Tumors of chest wall represent a variant entity. Most of them arise from metastasis of malignant tumors or from local invasion by contiguity. However, non-Hodgkin's lymphomas of the chest wall are extremely rare; only a few cases have been reported in the literature.

Primary malignant non-Hodgkin's lymphoma of the breast: a study of seven cases and literature review.

Introduction: Primary breast lymphoma is an uncommon disease with poor clinical outcome. Breast lymphomas present less than 0.5% of malignant breast neoplasms and 2.

Systemic treatment and targeted therapy in patients with advanced hepatocellular carcinoma.

Background: ADVANCED HEPATOCELLULAR CARCINOMA (HCC) IS A MALIGNANCY OF GLOBAL IMPORTANCE: it is the sixth most common cancer and the third most common cause of cancer-related mortality worldwide. Despite decades of efforts by many investigators, systemic chemotherapy or hormone therapy has failed to demonstrate improved survival in patients with HCC..

Metastatic Ewing's sarcoma/PNET of kidney in 40 year old patient.

Introduction: Primary renal Ewing sarcoma/PNET is an uncommon and very aggressive tumor.

Presentation Of Case: : We report the case of a young woman who underwent nephrectomy for a renal mass from unknown etiology. Histologic analysis found small tumoral cells in rosette formation, and immunohistochemical staining was positive for CD99, and focally positive for vimentin and Protein S-100.

Successful management of primary non Hodgkins lymphoma of the cranial vault.

Primary bone lymphoma (PBL) is a relatively uncommon entity. However, involvement of the cranial vault is an unusual manifestation of aggressive non-Hodgkin's lymphoma. We report the case of a 42-year old immunocompetent woman who presented with an enlarging mass involving the right parietal bone.

Metastatic ameloblastoma responding to combination chemotherapy: case report and review of the literature.

Background: Ameloblastoma is a rare benign odontogenic tumor with locally aggressive behavior and a high recurrence rate. When metastases occur, which are uncommon, lungs constitute the most frequent site involved. Malignant ameloblastomas are different from ameloblastic carcinomas.

[Psychosocial impact of cancer on Moroccan adolescent and young adult: experience of National Institute of Oncology of Rabat].

Cancer is an uncommon disease; its imaginary concept is very particularly on adolescent and young adults. It disturbs their lives on the whole. The purpose of this study is to describe the specific psychosocial effects of cancer on adolescent and young adults in Moroccan population in order to help physicians educate and counsel future young patients and their families.

Rare recurrence of a rare ovarian stromal tumor with luteinized cells: a case report.

Introduction: Sex cord-stromal tumors of the ovary are uncommon. They behave unpredictably and often have a late recurrence, making counseling, management, and prediction of prognosis challenging.

Case Presentation: A 52-year-old Moroccan woman with an sex cord-stromal tumors underwent a bilateral oophorectomy.

Biotherapy in the Adjuvant Treatment of Colorectal Cancer.

The use of adjuvant chemotherapy has improved survival in early-stage colon cancer. Ongoing adjuvant clinical trials are evaluating the addition of targeted therapies to standard chemotherapy regimen. Preliminary results with bevacizumab were disappointing.

Metastatic collecting duct carcinoma of the kidney treated with sunitinib.

Collecting duct carcinoma (CDC) of the kidney is a rare and aggressive malignant tumor arising from the distal collecting tubules which has been shown to have a poor response to several kinds of systemic therapy. We present a case of metastatic CDC that responded favorably to a multiple tyrosine kinase inhibitor, sunitinib, achieving a partial response in both lung and skeletal metastases. To our knowledge, this is the first report showing therapeutic activity of sunitinib against CDC.

Male breast cancer: a report of 127 cases at a Moroccan institution.

Background: Male breast cancer (MBC) is a rare disease representing less than 1% of all malignancies in men and only 1% of all incident breast cancers. Our study details clinico-pathological features, treatments and prognostic factors in a large Moroccan cohort.

Findings: One hundred and twenty-seven patients were collected from 1985 to 2007 at the National Institute of Oncology in Rabat, Morocco.

Diagnostic challenge for ovarian malignant melanoma in premenopausal women: primary or metastatic?

Background: In the ovary, metastatic malignant melanoma may be confused with primary malignant melanoma and presents a diagnosis challenge. Most cases are associated with disseminated diseases and poor prognosis. We present this case report of a metastatic ovarian malignant melanoma simulating primary ovarian cancer.
