RESUMEN

Pilomatricoma (calcifying epithelioma of Malherebe) is an uncommon skin tumour that occurs predominantly in young people. No studies are available from the Indian subcontinent on pilomatricoma. We analyzed records of 18 cases of pilomatricoma seen during 5 years period (1995-99). There were 16 females and 2 males and their age ranged from 5 to 60 years. All patients had solitary lesions in 10 out of 18 cases (55.5%), the tumour was located in head and neck region including 5 cases (27%) where it involved orbital margin and eye-brow. In only 2 out of 18 cases, a clinical diagnosis of pilomatricoma was suggested. In addition to the secondary changes described in previous studies, we observed additional changes like myxoid change, oedema fluid and necrosis with karyorrhectic debris in few of these tumours. Making a clinical diagnosis of pilomatricoma can be difficult. The final confirmation is by histopathological examination only.

RESUMEN

Epithelioid haemangioendothelioma is a rare primary malignant tumour of the bone that accounts for less than 1% of all primary bone malignancies. The case discussed here is of a 35 years old male who presented with gradually increasing left infrascapular mass attached to 10th rib. X-ray showed an expansile lytic lesion in 10th rib. On FNA the diagnOsis of fibrous dysplasia or fibrous-histiocytic lesions was suggested. The lesion was excised along with adjacent rib. Histopathological examination showed features of epithelioid haemangioendothelioma. Immunohistochemistry revealed focal factor VIII related antigen positivity.
