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.

Frequency and types of mutations in Moroccan patients with non-small cell lung cancer.

Background: Mutations in the epidermal growth factor receptor () gene are commonly observed in non-small cell lung cancer (NSCLC), particularly in adenocarcinoma histology. The frequency of 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.

The Frequency and Specific Features of Rare Epidermal Growth Factor Receptor Mutations in Moroccan Patients with Lung Adenocarcinoma whose Tumors harbor positive EGFR mutations.

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.

Frequency of anaplastic lymphoma kinase rearrangements in Moroccan patients with non small cell lung cancer: a multi-institutional national retrospective study.

Background: Anaplastic lymphoma kinase (ALK) rearrangement is a predictive factor of response to ALK inhibitors in non small cell lung cancer (NSCLC). The prevalence of ALK rearrangements is well known in Whites and Asians. However, data identifying the frequency of this rearrangement in Moroccan and North African population are lacking.

[Liposarcoma in the renal compartment: about two cases and literature review].

Retroperitoneal sarcomas are rare and heterogeneous tumors. We here report two cases of liposarcoma in the renal compartment with a literature review in order to emphasize on the anatomical and surgical features of this tumor location and on its possible prognostic implications. The first reported case was a 45-year old female patient with liposarcoma at the level of the left renal compartment.
