Dermatofibrosarcoma protuberans - a recurrent lesion with unusual presentation in the parotid region.

Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous malignant neoplasm consisting of relatively monomorphous mononuclear spindle cells that show diffuse CD34+ positivity. Management of this lesion poses problem because of its infiltrative margins and high propensity for local recurrence and rare distant metastasis. It is said that clear margins with minimal removal of normal tissues can be achieved by Mohs' micrographic surgery, which is particularly important in head and neck locations where the presence of vital anatomical structures and aesthetic considerations hinders a wide surgical excision.
