A rare case of small cell carcinoma of the ovary, hypercalcemic type.

Small cell carcinoma of ovary, hypercalcemic type (SCCOHT) is an unusual malignant tumor that most commonly affects young women. Unfortunately, it has a very poor prognosis. We describe here an unusual case of a Moroccan young woman with a left ovarian mass and a symptomatic hypercalcemia.

Correlation between KRAS and NRAS mutational status and clinicopathological features in 414 cases of metastatic colorectal cancer in Morocco: the largest North African case series.

Background: Advances in molecular biology have improved understanding of the molecular features of carcinogenesis and progression of colorectal cancer. It is clear that the efficacy of anti-EGFR depends upon the RAS mutational status, since any mutation in RAS is associated with resistance to anti-EGFR therapy. The aim of this study is to report the largest North African description of KRAS and NRAS status in metastatic colorectal cancer and to describe the association of these mutations with clinicopathological characteristics.

An unusual variant of lipoma: case report.

Osteo-lipoma is a very rare benign tumor with a good prognosis. It is composed mainly of mature fatty tissue with a bony component. The diagnosis is based on the histological study, given the clinical and radiological characters that can simulate other benign or malignant pathologies.

Breast metastasis 18 years after nephrectomy for renal cell carcinoma: a case report.

Metastasis of renal clear cell carcinoma (RCC) to the breast is exceptional. Breast metastases of extra-mammary tumors are rare and usually involve melanoma, lymphoma or leukemia. We report the case of a patient with breast metastasis of renal clear cell carcinoma occurring 18 years after nephrectomy.

Assessment of deep learning algorithms to predict histopathological diagnosis of breast cancer: first Moroccan prospective study on a private dataset.

Objective: Breast cancer is a critical public health issue and a leading cause of cancer-related deaths among women worldwide. Its early diagnosis and detection can effectively help in increasing the chances of survival rate. For this reason, the diagnosis and classification of breast cancer using Deep learning algorithms have attracted a lot of attention.

Adenoid Cystic Carcinoma of the Uterine Cervix: A Report of 2 Cases.

Adenoid cystic carcinoma is malignant tumor that exceptionally occurs in the uterine cervix. It is mostly seen in postmenopausal women and has an aggressive clinical course. We report two cases of an adenoid cystic carcinoma associated with a high grade squamous intraepithelial lesion and invasive squamous cell carcinoma of the uterine cervix and discuss briefly its clinical and pathological characteristics.

Primary carcinosarcoma of the skin.

Primary cutaneous carcinosarcoma is a biphasic tumour containing both malignant epithelial and malignant mesenchymal elements. The disease is a rare malignant skin tumour of unknown aetiology with significant potential to recur locally and to metastasise. Surgery is the primary therapeutic modality.

[Solitary myofibroma of the mandible: a case report].

Objectives: Infantile myofibromatosis (IMF) are integrated in the group of fibromatosis juvenile-type which are benign mesenchymal lesions, characterized morphologically by a proliferation of fibroblasts and myofibroblastes, with perivascular pattern. Through a case of solitary myofibroma of the mandible, we will emphasize anatomo-clinical features and differential diagnosis.

Materials And Methods: We report a case illustrating solitary myofibroma of the mandible in 18 month old infant.

[Congenital vascular leiomyosarcoma].

Introduction: Vascular leiomyosarcoma is a conjunctive tumor which develops in the smooth muscle cells of vessel walls. Proximal vascular leiomyosarcoma involving the large vessels and peripheral vascular leiomyosarcoma which develops in the vascular pedicles of the limbs and subcutaneous vessels are distinguished.

Observation: We report the case of a 6-year-old child who presented from birth a peripheral vascular leiomyosarcoma.

[Giant cell tumor of soft tissues. Report of two cases].

We report two cases of giant-cell tumour of soft tissue (TCG-TM). The first case occurred in a 26-year-old woman presenting with a subcutaneous tumour of the left leg. Pathological study revealed a tumour comparable to benign giant cell tumour of bone.
