Dermatofibrosarcoma protuberans of the toe. Findings on multiple imaging modalities

Area of Science:

• Oncology
• Radiology
• Dermatopathology

Background:

• Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing malignant neoplasm of the skin, originating from dermal fibroblasts.
• DFSP typically presents in adults, with a predilection for the trunk and proximal extremities, and rarely occurs distal to the knees.
• Early diagnosis and appropriate management are crucial due to its high recurrence rate and potential for deep tissue infiltration.

Observation:

• This report details an exceptionally rare case of dermatofibrosarcoma protuberans located on the toe.
• The tumor's presentation in this distal location is highly unusual, challenging typical clinical expectations.
• Diagnostic imaging modalities were employed to characterize the lesion and assess its extent.

Findings:

• Imaging findings, including [mention specific modalities if known, e.g., MRI, CT, Ultrasound], provided valuable information for the diagnosis and surgical planning.
• Histopathological examination confirmed the diagnosis of dermatofibrosarcoma protuberans.
• The case underscores the importance of considering rare presentations of common tumors.

Implications:

• This case expands the known spectrum of dermatofibrosarcoma protuberans locations, emphasizing the need for vigilance in diagnosing unusual soft tissue tumors.
• Understanding the imaging characteristics of DFSP in atypical locations can aid radiologists and clinicians in early detection.
• Further research into the specific behavior and treatment of DFSP in distal extremities may be warranted.
