Abstract Background: Hemangiopericytoma occurs with increasing frequency in 5th decade of life and has prediction for retroperitoneum and extremities. A case of a local recurrence and metastases of hemangiopericytoma is described. Case presentation: Recurrence of hemangiopericytoma in the greater omentum and the jejunal mesentery as well as metastases in the retroperitoneal space were diagnosed in a 61-year-old patient who had a hemangiopericytoma of the greater omentum excised 18 years before. Conclusion: Because of the rarity of this disease and its typical clinical course associated with late recurrence and metastases, the authors decided to present this case emphasizing the necessity of systematic oncological follow-up after the end of treatment.
Background Hemangiopericytoma is a tumor originating from the vascular pericytes of Zimmermann. Most frequently it occurs in patients aged 40 and above with its main localization in the retroperitoneum, pelvis and lower extremities [1-3], however, it may occur at any age in almost any part of body [4]. One of the typical features of this tumor is that both metastasis and recurrence could become apparent even after several years in remission [5-7]. We report the case of a local recurrence and metastases in the retroperitoneum infiltrating the liver and diaphragm in a 61-year-old patient operated on due to a hemangiopericytoma of the greater omentum 18 years before.
Case presentation A 61-year-old patient was admitted to the Department of Transplantation and General Surgery with a tumor diag-
nosed in the left lumbar and retroperitoneal space. Eighteen years before he had been operated for a tumor of the greater omentum with histopathological diagnosis haemangiopericytoma omenti maioris, until now with no recurrence nor distant metastases were found. On admission the patient was in good general condition with left lumbar pain and a mobile tumor in this area. Abdominal ultrasonography (US) and computed tomography (CT) revealed a retroperitoneum spac
