Dermatofibrosarcoma protuberans: an unusual case of neck swelling.
J Pak Med Assoc Jan ;62(10):1089-91.

Dermatofibrosarcoma protuberans (DFSP) is a relatively intermediate to low grade malignant tumour with high proclivity for local recurrence if excised inadequately. It is a locally aggressive tumour and despite sharing some histological features with fibrohistiocytic tumours, it tends to grow in a more infiltrative manner. We are reporting this rare tumour in a 30-year-old woman where the diagnosis of DFSP was confirmed histologically and by positive immunomarkers at immunohistochemistry.
