This paper presents a case report of a primary lymphoma of the appendix as the underlying cause of acute appendicitis. As in previous reported cases, diagnosis can only be made intraoperatively followed by a proven histopathological picture as they present with an acute surgical abdomen.
Haemangiopericytoma (HPC) is a rare tumour with a predilection for the central nervous system. Though previously thought to originate from the meninges and ventricular walls, HPC's are currently accepted as distinct mesenchymal neoplasms unrelated to meningiomas. Haemangiopericytomas have been previously reported to be associated with the production of insulin like growth factor II (IGF-II) and hypoglycaemia. A case of a 61-year-old poorly controlled diabetic lady with a rare presentation of an abdominal haemangiopericytoma is discussed. A laparoscopic assisted resection of the massive lobulated tumour arising from the parietal peritoneum with dense attachment to the diaphragm and the liver was performed with an uncomplicated postoperative recovery. Control of the patient's diabetes improved dramatically following surgery and the rare association of hyperglycaemia and HPC, which has not been previously described, is elaborated upon in this report.
