RESUMO
Hemorrhagic cystitis is a syndrome associated with certain disease states as well as exposure to drugs, viruses, and toxins. It manifests as diffuse bleeding of the endothelial lining of the bladder. Treatment includes intravesical, systemic, and nonpharmacologic therapies, all of which have advantages and disadvantages.

Haemangiopericytoma is a rare, vascular soft tissue tumour originating from the pericytes surrounding capillaries. We report a case of haemangiopericytoma in the sigmoid mesocolon and are aware of only one previously case. A 61-year-old man was referred with a left iliac fossa mass. At operation, a 10-cm diameter mass was found to be arising from the sigmoid mesentery (Fig. 1). The mass did not involve the bowel wall and there was no clinical evidence of metastatic disease. A sigmoid colectomy with primary anastomosis was performed. The patient made an uneventful recovery. Pathological assessment of the specimen revealed a 95 x 70 x 50 mm(3), purple, lobulated mass within the sigmoid mesocolon adjacent to the bowel. Immunohistological analysis (positive CD34, focal factor VIII) was consistent with a diagnosis of a haemangiopericytoma. Complete excision with adequate margins remains the treatment of choice. We therefore suggest that patients be carefully followed for long periods and advised of the risk of long-term relapse.
