Angiomyolipoma of stomach is extremely rare. Only 1 case has been reported earlier. We report a case of 40-year-old female who presented with gastrointestinal bleeding. Upper gastrointestinal endoscopy suggested a polypoidal growth in the stomach. Biopsy from the growth was suggestive of mesenchymal tumor. The contrast-enhanced computed tomography of abdomen revealed a pedunculated 4×3 cm, intramural lesion at the junction of first and second parts of duodenum, likely lipoma. The stalk seemed to be arising from distal stomach. At laparoscopy, a highly mobile lesion was observed arising from the posterior wall of stomach. Wedge resection of the lesion was performed laparoscopically after doing an anterior gastrotomy. The final diagnosis on histopathology was a gastric angiomyolipoma.

Hepatic angiomyolipoma is a rare and possibly cancerous mesenchymal tumor that consists of three components: blood vessels, smooth muscle cells, and adipose tissue. In this paper, we reported a case of a 36-year-old man who had a giant hepatic angiomyolipoma with spontaneous rupture and hemorrhage. The patient was admitted to our hospital with sudden upper abdominal pain for 3 h.

Background: Birt-Hogg-Dubé syndrome (BHDS) is a rare autosomal dominant genodermatosis characterized by benign growth of the hair follicles, the presence of pulmonary cysts, spontaneous pneumothorax, and bilateral renal tumors that are usually hybrid oncocytic or multifocal chromophobe renal cell carcinoma. The diagnosis is confirmed by the presence of a pathogenic variant in the tumor suppressor folliculin (FLCN) gene mapped at 17p11.2.

Gastric angiomyolipoma (AML) is extremely rare, with only 3 cases reported in English literature, all of which presented with upper gastrointestinal bleed, either in the form of hematemesis or melena. A 42-year-old man presented with upper gastrointestinal bleed, the source of which was found to be a large mass in the stomach, which was shown histologically to be gastric AML. This is the fourth but largest tumor (9 × 6 × 5 cm) to be reported to date.

The majority of pancreatic neuroendocrine tumors (PNETs) are sporadic while 10-15% are attributable to one of several familial cancer syndromes. Hereditary forms are more commonly associated with Multiple Endocrine Neoplasia Type I and von Hippel Lindau Syndrome. However, patients with Tuberous sclerosis complex also have an increased incidence of PNETs.

- Two patients with extrarenal retroperitoneal angiomyolipoma were initially misdiagnosed as having perinephric liposarcoma, highlighting the challenges in correctly identifying these types of tumors.
- Patient 1, a 66-year-old man, had a tumor near the kidney that was tracked for 18 months, leading to surgical removal after its enlargement was noted.
- Patient 2, a 56-year-old man, was diagnosed through routine ultrasound and underwent surgery based on imaging findings, but both cases ultimately confirmed the presence of extrarenal angiomyolipoma, underscoring the difficulty in distinguishing it from liposarcoma using advanced imaging techniques like 18F-FDG PET/CT
