ABSTRACT
Adenocarcinoma and lymphoma represent the two most common malignant tumours of the stomach, with both neoplasms being associated with infection by Helicobacter pylori. However, the presence of lymphoma and adenocarcinoma in the same patient is a rare entity with synchronous neoplasms being more common than metachronous types. We report a case of stage IV gastric MALT lymphoma of the gastric angle with infiltration of the bone marrow successfully treated with chemotherapy and the occurrence of metachronous early gastric adenocarcinoma of the fundus presenting 1 year after the diagnosis of the lymphoma.

Intra-abdominal heterotopic ossification is extremely rare with only approximately 30 cases having been reported. While most reported cases have involved the mesentery, ossification of the peritoneum is even rarer. The pathogenesis remains undetermined but is generally considered a reactive process in response to various stimuli. Histologically, it is composed of a peripheral area with bone formation and a central area of reactive hypercellular fibrous tissue. We report a rare case of intra-abdominal heterotopic ossification of the parietal peritoneum following traumatic splenic rupture.
