A case of cutaneous mesenchymal haemangiopericytoma-like tumour affect
ing a 17-year-old male is presented. Clinical features were non-specif
ic. The tumour was studied by light, electron microscopy and immunohis
tochemistry. The results of these studies suggested the diagnosis of a
mesenchymal, poorly-differentiated tumour showing features of haemang
iopericytoma. The clinical course after surgery was uneventful after a
9-month follow-up period.
