“…To the best of our knowledge, only eight cases of HPC of the bladder have been previously reported in the English literature (Table I) (2–9). In these cases and including the current study, the mean age of the patients at the time of diagnosis is 48.5 years (range, 29–72 years), with a predominance of females (six vs. two).…”

“…HPC mostly arises in the lower extremities, retroperitoneum and head and neck area (2–4). To the best of our knowledge, only eight cases of HPC of the bladder have been previously reported in the English literature (2–9). The rarity of HPC of the bladder makes it difficult to predict the clinical behaviour and determine the appropriate treatment of this tumour.…”

Haemangiopericytoma (HPC) is a rare soft-tissue tumour with great histological variability and unpredictable clinical and biological behaviour. HPC of the bladder is exceedingly rare and carries uncertain malignant potential. The current study reports a case of HPC of the bladder in a 48-year-old female, who was admitted to the Sir Run Run Shaw Hospital (Hangzhou, China) due to a large bladder mass. The patient exhibited no mass-related symptoms, such as pain, gross haematuria or urinary irritation. Seven years prior to admission, the patient underwent surgical resection of a bladder mass, which was determined to be HPC. Computed tomography scans showed a well-defined, heterogeneously enhancing solid cystic mass in the bladder. The patient underwent complete excision of the tumour and a partial cystectomy. The histopathological diagnosis was HPC of the bladder. The post-operative recovery was uneventful and no evidence of recurrence or metastasis was identified during two years of follow-up. The clinical and histological features, and the treatment and prognosis of this tumour are discussed together in the present study, with a review of the literature.

Non-Adenomatous Non-Epithelial Carcinoma (Hemangiopericytoma) of Prostate Treated with Conservative Surgery Followed by Adjuvant Chemoradiation

et al. 2009

Hemangiopericytoma is a malignant vascular tumour of soft tissue. Microscopically, the tumour shows tightly packed cellular areas surrounding thin-walled branching blood vessels. Traditionally these tumours are treated using wide surgical excision. Only a very few cases of hemangiopericytoma of the prostate have been described worldwide. The feasibility of managing such a case with a combination of conservative surgery and adjuvant anti-malignancy treatment is unexplored.Here, we report a case of hemangiopericytoma of the prostate treated with local excision, with preservation of prostate, followed by adjuvant radiotherapy (40 Gy in 20 fractions to pelvis followed by 24 Gy in 12 fractions as boost to prostate) and chemotherapy (doxorubicin and iphosphamide). Post-treatment computed tomography scan after 4 weeks showed regression of pelvic lymph nodes and a normal-appearing prostate. Levels of serum prostate-specific and carcinogenic embryonic antigen were normal throughout the period of treatment. To date, followup has been uneventful, except for occasional bouts of diarrhea.We conclude that conservative surgery followed by adjuvant radiation and chemotherapy, with subsequent close follow-up, may adequately control localized disease in selected cases of hemangiopericytoma of the prostate. The role of conservative surgery in tumours located at other sites has yet to be defined.

“…Moreover, it is classified as a soft-tissue vascular tumor originating from pericytes, which occurs commonly in the extremities, pelvis, head and neck, and meninges (2,3). On the other hand, HPC is rarely encountered in urogenital system (4)(5)(6). Renal HPC is also extremely rare tumor and only 41 case reports have been previously documented (7).…”

Metastatic renal hemangiopericytoma: A rare case report

et al. 2009

View full text Add to dashboard Cite

The hemangiopericytoma (HPC) of the kidney is extremely rare perivascular neoplasm. There are no specific radiological or clinical findings that can aid in preoperative diagnosis. In the world literature, only 41 cases of renal HPC have been previously documented. We report on a 56-year old woman with renal HPC of the right kidney who had lung metastasis at the time of diagnosis. The right radical nephrectomy was performed and the combination chemotherapy was given, postoperatively. After 3 cycles of chemotherapy, disease was stable, but progression was seen at the end of 6 courses of chemotherapy. The patient died due to progression of disease ten months later after the diagnosis. We suggested that for patients present with renal mass, renal HPC as well as the other renal tumors should be considered in the differential diagnosis
