Programmed death-ligand 1 expression is associated with fibrosarcomatous transformation of dermatofibrosarcoma protuberans
Dermatofibrosarcoma protuberans (DFSP) is a locally invading tumor, characterized by the presence of the collagen type I α 1 (COL1A1)-platelet-derived growth factor (PDGF) β fusion gene. We herein report the case of a 31-year-old man with a history of resection of an abdominal wall DFSP. The patient presented with chest pain and a computed tomography scan revealed a large mass in the posterior ...
متن کاملDermatofibrosarcoma protuberans with fibrosarcomatous transformation*
To the Editor, Dermatofibrosarcoma protuberans (DFSP) is an uncommon sarcoma of the skin and soft tissue with an intermediate level of malignancy. DFSP with fibrosarcomatous differentiation (FS-DFSP) is a rare variant of DFSP, involving greater aggression, higher rates of local recurrences and a higher metastatic potential. We describe the case of a 70-year-old woman who presented with a painle...
متن کاملDermatofibrosarcoma protuberans with fibrosarcomatous transformation of the head and neck
Dermatofibrosarcoma protuberans (DFSP) is a rare cutaneous neoplasm associated with a high cure rate. We present a case of aggressive DFSP with fibrosarcomatous areas in the head and neck. A 28-year-old Mediterranean female presented with a 45-day history of rapidly growing cutaneous lesion of the face. Surgical biopsy confirmed the diagnosis of DFSP. Subsequently, the patient underwent wide lo...
متن کاملCongenital dermatofibrosarcoma protuberans with fibrosarcomatous and myxoid change.
This report describes a case of congenital dermatofibrosarcoma protuberans (DFSP) with fibrosarcomatous (FS) and myxoid areas. Immunohistochemical results showed that tumour cells in ordinary DFSP areas were diffusely positive for CD34, whereas in the FS and myxoid areas, few tumour cells were positive for this antigen. Ki-67 positive tumour cell numbers were greater in the FS (11.8%) and myxoi...
متن کاملA Fibrosarcomatous ("High-Grade") Variant of Dermatofibrosarcoma Protuberans (DFSP)
Dermatofibrosarcoma protuberans (DFSP) is a relatively uncommon soft tissue tumor with intermediate-to-low grade malignancy. There is usually little nuclear pleomorfism and only low to moderate mitotic activity. Conventional DFSP, usually have fewer than 5 mitotic figures/10 high-power fields. We describe a case of a 74year old male patient who presented to the surgical clinic with active bleed...
