Metastatic presentation of dermatofibrosarcoma protuberans as massive lower gastrointestinal bleed.

ABSTRACT

Dermatofibrosarcoma protuberans (DFSP) is an aggressive tumour with multiple local recurrences and rare metastatic potential. Fibrosarcomatous transformation occurs in a few cases of DFSP which makes them more aggressive in terms of recurrence and metastasis. Here we report the case of a woman in her late 30s who presented with massive lower gastrointestinal (GI) bleeding with a history of multiple surgeries for DFSP on her anterior abdominal wall. The bleeding source was identified to be a mass lesion in the jejunum, which was excised. The patient recovered well and the histopathology revealed fibrosarcoma of the jejunum. Follow-up investigations showed multiple lung nodules, ascites and abdominal lymph nodes suggesting progressive disease. She is currently receiving chemotherapy and progressing well 3 months postoperatively. Patients with fibrosarcomatous changes within DFSP must be followed up closely as it is associated with increased metastatic potential.
