Spontaneous splenic rupture as a primary manifestation of angiosarcoma: a case report.

Angiosarcoma, a rare endothelial cell tumor, accounts for < 2% of all sarcomas, typically affecting elderly patients. We present the case of a 62-year-old male with a history of hypertension and ischemic heart disease, who initially presented with severe lower back pain. Subsequent imaging revealed a ruptured splenic lesion and multiple liver lesions, leading to a diagnosis of stage 4 angiosarcoma.

Adenocarcinoma of the appendix presenting as chronic small bowel obstruction: A case report.

Appendiceal carcinoma, a rare malignancy comprising less than 1% of gastrointestinal cancers, often presents diagnostic challenges due to its atypical symptoms. This report details a 68-year-old female with a history of severe anemia, gastrointestinal bleeding, and persistent abdominal symptoms, ultimately diagnosed with chronic small bowel obstruction caused by an appendiceal adenocarcinoma. Despite initial treatment for Helicobacter pylori-induced gastritis, her symptoms persisted, prompting further imaging that revealed a narrowed small bowel segment.

A rare case of gastric schwannoma mimicking GIST: diagnostic and therapeutic approach.

Gastric schwannomas are rare, benign neurogenic tumors originating from Schwann cells within the gastrointestinal tract, comprising only 0.2% of all gastric tumors. This report presents the case of a 32-year-old female patient who experienced severe periumbilical pain, nausea, and vomiting, ultimately diagnosed with gastric schwannoma.
