A Rare Case of Tuberculosis Revealed by Acute Appendicitis: A Case Report.

According to the World Health Organization (WHO), tuberculosis (TB) is the 13th cause of death worldwide and the second infectious killer after HIV. It is an endemic disease in Morocco. Isolated appendicular TB is an uncommon form of extrapulmonary TB.

Epidemiological and clinical characteristics of children with peripheral neuroblastic tumors: a study on a Moroccan population.

Purpose: Peripheral neuroblastic tumors are the most common extracranial cancers found in children, and they are characterized by a diverse spectrum of clinical manifestations and heterogeneous behaviors. This study aimed to investigate the epidemiological and clinical characteristics of children with peripheral neuroblastic tumors admitted to the Department of Pediatric Hematology and Oncology of the Hospital August 20 in Casablanca.

Methods: The medical files of 48 children with peripheral neuroblastic tumors addressed to our department between February 2018 and February 2023 were reviewed.

Chromophobe renal cell carcinoma with liposarcomatous dedifferentiation: a case report.

Chromophobe renal cell carcinoma with liposarcomatous dedifferentiation is a very extremely rare tumor and only few cases have been reported in the literature. Here we report a case of a 37-year-old woman who presented with a pain and a palpable mass in the right flank. The abdominal computed tomography (CT) scan found a renal tumor and the patient underwent a right radical nephrectomy with adrenal gland resection.

Anatomo-Clinical Aspects of Retinoblastoma: A Series of 144 Cases.

Retinoblastoma (RB) is the most common intraocular primary malignancy for infants and young children. The tumor is bilateral in 40% of cases and unilateral in 60% of cases. The hereditary form is due to a germinal mutation in the RB1 tumor suppressor gene.

Ki-67 proliferation index to further stratify invasive breast cancer molecular subtypes: Northern African comparative cohort-study with external TCGA-BRCA and METABRIC validation.

Introduction: breast cancer (BC) is a malignancy with very high incidence and mortality in Africa, especially in Western Africa, where more than 25 thousand deaths are registered every year. Not all BC have the same prognosis, and being able to personalize treatment and predict aggressiveness is of crucial importance. The purpose of our study is to explore further subdivisions associated with prognosis, beyond breast cancer molecular classification that is routinely established in pathology departments.

Solid pseudopapillary tumor of the pancreas: a rare entity in children.

Solid pseudopapillary tumors (SPTs) constitute 0.2 to 2.7% of non-endocrine primary tumors of the pancreas and comprise the majority (70%) of pediatric pancreatic neoplasms.

Primary Malignant Deciduoid Mesothelioma: A Challenging Diagnosis.

Primary malignant deciduoid mesothelioma is a rare subtype of epithelioid mesothelioma that was first described in the peritoneum in young women without a history of asbestos exposure. It was thought to be a distinct clinicopathologic entity with ominous prognosis; recent studies have better characterized this entity. On morphology, primary malignant deciduoid mesothelioma is characterized by cytomorphologic features resembling decidualized tissue.

Lead poisoning in children: a case report.

Lead colic is a rare cause of abdominal pain. The diagnosis of lead poisoning is most often mentioned in at risk populations (children, psychotic). We report the case of a 2 year old child that was presented for acute abdomen.
