Molecular classification improves preoperative risk assessment of endometrial cancer.

Objective: We aimed to evaluate the performance of endometrial cancer (EC) molecular classification in predicting extrauterine disease after primary surgery alone and in combination with other clinical data available in preoperative setting.

Methods: Retrospective single-center observational study including patients with endometrial adenocarcinoma treated with primary surgery between December 1994 and May 2022. Molecular profiling was performed using immunohistochemistry of p53, MLH1, PMS2, MSH2 and MSH6; and KASP genotyping of the 6 most common mutations of POLE gene.

A case of primary mesenteric synovial sarcoma: a challenging presentation.

Background: Synovial sarcoma is an uncommon soft tissue malignancy that mainly occurs near tendon sheath and bone joints. Primary intra-abdominal location is exceedingly rare and characterized by non-specific clinical signs.

Case Presentation: We report the case of a young female without medical history who presented with acute abdominopelvic pain.

Sarcoid-Like Reaction in the Kidney Following Rituximab for Mantle Lymphoma in a 60-Year-Old Man.

The sarcoid-like reaction is a rare autoinflammatory disease that can affect lymph nodes or organs but does not meet the diagnostic criteria for systemic sarcoidosis. Several drug classes have been associated with the development of a systemic sarcoid-like reaction, which defines drug-induced sarcoidosis-like reactions and can affect a single organ. Anti-CD20 antibodies (rituximab) have rarely been reported as responsible for this reaction and this adverse effect has mainly been described during the treatment of Hodgkin's lymphoma.

Adult Langerhans' cell histiocytosis with multisystem bone and lung involvement: About a case.

Introduction: Langerhans cell histiocytosis (LCH) is a rare systemic disease characterized by the abnormal overproduction of histiocytes that tend to infiltrate single or multiple organ systems leading to significant tissue damage. Although LCH can involve various organs including bone, skin, and lymph nodes, multisystem involvement of LCH is rare in adults.

Case Presentation: We report the case of a 31-year-old man with LCH involving his lungs and bone.

East-central Tunisian patients with colorectal adenocarcinoma: a comparative study of the clinicopathological features between patients under 50 years of age and older patients.

Introduction: Colorectal cancer is a major public health problem. In younger patients, its incidence continues to rise and its prognosis appears to be worse. Its treatment is based on curative surgery associated with neo-adjuvant and adjuvant therapies.
