Fine needle aspiration cytology of cutaneous vascular tumours

We have studied 12 cutaneous vascular tumours by means of fine-needle aspiration cytology (FNAC): six capillary haemangiomas, one cavernous haemangioma, one Masson's pseudo-angiosarcoma, two angiosarcomas, one benign haemangioendothelioma and one glomus tumour. We describe the main cytopathological findings and we discuss the differential diagnosis in each case. We consider that the cytopathological findings of the above lesions, evaluated in the context of the clinical findings, are sufficiently characteristic for us to be able to make a definitive diagnosis. We believe that FNAC can play an important part in the diagnosis and therapeutic planning of these tumours.
