INTRODUCTION Dermatofibrosarcoma protuberans is an uncommon low-grade soft tissue sarcoma with a high potential for recurrence as it has irregular finger like extensions. CASE DESCRIPTION We report a case of a large, recurrent dermatofibrosarcoma protuberans in a child involving the anterior abdominal wall, which posed a challenge for reconstruction. Peritoneum sparing full thickness resectio...

BACKGROUND Processing multiple tissue sections in large Mohs cases is time consuming and labor intensive. OBJECTIVE To present innovative laboratory techniques to facilitate processing of large Mohs cases. METHODS A method for processing a large dermatofibrosarcoma protuberans Mohs case is outlined. RESULTS Modifications in tissue processing and equipment employed in a large Mohs case are...

Dermatofibrosarcoma protuberans with fibrosarcomatous transformation (DFSP-FS) is a rare variant, higher rates of recurrence and metastasis than DFSP. Detection the collagen type I alpha 1 (COL1A1)–platelet-derived growth factor beta chain (PDGFB) fusion gene useful for diagnosis In this letter, we report case DFSP-FS, focusing on expression COL1A1-PDGFB in lesions. Increased may be associated ...
