Splenic Lymphoma Mimicking a Hydatid Cyst Causing a Diagnostic Challenge: A Case Report.

Splenic lymphoma, particularly primary splenic diffuse large B-cell lymphoma (PS-DLBCL), is a rare malignancy that often presents with nonspecific symptoms, complicating diagnosis. This case report describes a 44-year-old female with left flank pain and nausea whose imaging studies, including ultrasound and CT, revealed a well-defined heterogeneous lesion in the spleen and left pleural effusion, initially suggesting a hydatid cyst. Despite negative serological tests for echinococcosis, clinical suspicion remained due to the endemic presence of the disease.

Novel presentation of acalvaria with clavicular absence: A case report.

Rationale: Acalvaria is an exceptionally rare congenital disorder marked by the absence of flat bones of the cranial vault, dura mater, and associated muscles, while the facial bones and base of the skull remain intact. Typically, the central nervous system is unaffected. Due to their extreme rarity, reported cases in the literature are infrequent.

Partial midgut agenesis in a premature neonate: A case report and literature review of small bowel agenesis.

Introduction And Importance: Small bowel agenesis (SBA) is a rare congenital abnormality characterized by the absence of part or all of the small intestine, leading to significant disruptions in nutrient absorption. While hereditary factors are suspected to contribute, the precise etiology of SBA remains largely unknown. Prenatal ultrasonography is typically used for diagnosis, but postnatal diagnosis can be based on clinical signs such as vomiting, abdominal distension, and poor growth.

Collision tumor of pulmonary adenocarcinoma and small lymphocytic lymphoma: A rare case of concurrent malignancies in the same lymph node.

Background: Collision tumors, a rare and challenging diagnostic entity, are characterized by the simultaneous presence of two distinct histological neoplasms within the same anatomical site. The underlying mechanisms of collision tumors are not well understood, though various theories attempt to explain this phenomenon.

Case Presentation: A 77-year-old Palestinian man, a heavy smoker with multiple comorbidities, presented with a productive cough and significant weight loss.
