Heterotopic mesenteric ossification (HMO) is a rare entity with few cases reported in the world literature. We report two cases. Both patients underwent an open gastric bypass with Roux-en-Y reconstruction procedure for morbid obesity and subsequently presented with gastrointestinal fistulae associated with HMO.

The carcinogenicity of nickel subsulfide, Ni3S2, for respiratory tract epithelium was studied in heterotopic tracheal transplants with doses of 1 and 3 mg Ni3S2 per trachea. Chemical determinations indicated that Ni3S2 persisted in the tracheas for seven to nine months. Ni3S2 showed marked toxicity for mucociliary epithelium, resulting in widespread atrophy and focal epithelial necrosis during ...

The author investigated histopathology of 615 consecutive duodenal specimens in our pathology laboratory. Computer search of the duodenal lesions was performed. Review of histological slides was done, when appropriate. The duodenal specimens were composed of 567 benign lesions and 48 malignant lesions. The 567 benign lesions were composed of chronic non-specific duodenitis in 334 cases (60.0%),...

Heterotopic bone is rarely found in the gastrointestinal tract. In the majority of reported cases, it was associatedwith malignant lesions [1,2], Peutz–Jeghers syndrome [3], and more rarely with inflammatory colonic polyps [4]. On reviewing the literature, we found only two cases of metaplastic bone accompanying hyperplastic gastric mucosa [5,6], and no case report of osseous metaplasia in gast...

BACKGROUND Splenosis refers to the heterotopic transplantation of splenic tissue following splenic trauma or splenectomy. Splenosis is typically asymptomatic and is often identified incidentally. CASE PRESENTATION We report a case of splenosis with colon and stomach invasion presenting as lower gastrointestinal bleeding and mimicking colonic gastrointestinal stromal tumour (GIST). The importa...
