Dermatofibrosarcoma protuberans--a clinicopathological study of ten cases.

Dermatofibrosarcoma protuberans is a low grade soft tissue tumour of skin and frequently recurs. It is a locally invasive tumour and hence wide excision is required to minimize recurrences. Tumours of low mitotic rate, less than 5 per 10 high power fields with a lesser degree of cellularity and anaplasia tend to follow a more indolent course than those with moderate to high grades with higher mitotic rates.
