Pericytic / perivascular neoplasms have traditionally been dominated by haemangiopericytoma. However, it is now recognized that the latter diagnostic category subsumes a wide variety of tumour types which share the presence of thin-walled branching blood vessels. If such lesions are otherwise classified, there remains only a small group of spindle cell lesions designated as haemangiopericytoma,...

Seaton, D. (1974). Thorax, 29, 595-598. Primary diaphragmatic haemangiopericytoma. Haemangiopericytomas are tumours consisting of vascular spaces surrounded by proliferating pericytes. Since this neoplasm was first described (Stout and Murray, 1942) over 300 cases have been reported. All tumours of the diaphragm are rare, and a primary diaphragmatic haemangiopericytoma has not been previously r...

Haemangiopericytoma is a rare soft tissue tumour, with great histological variability and unpredictable clinical and biological behaviour. The precise cell type origin is uncertain. One third of haemangiopericytomas occur in the head and neck area, but only a few cases have been reported regarding localization at the parapharyngeal space. Herewith, case is presented of a 54-year-old female, ref...

A 28-year-old woman presented with abdominal pain. Ultrasonograhic examination showed a pre-sacral mass, with complex structure and well delimitated cystss with thick walls. The resected specimen was 7.5 x 6 x 4 cm in size, well circumscribed and yellow in colour, with cysstic change containing mucoid-like material. Histologically, the lesion was composed of spindle cells with high cellularity ...
