Massive Facial Presentation of Dermatofibrosarcoma Protuberans.

Area of Science:

• Dermatology
• Surgical Oncology
• Pathology

Background:

• Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade malignant skin neoplasm.
• DFSP commonly affects the trunk and proximal extremities, but can occur in less frequent locations.
• Characterized by slow growth, local invasiveness, and low metastatic potential.

Observation:

• This case highlights an unusually large DFSP.
• The tumor was located in the preauricular region, a less common site.
• Clinical presentation of DFSP can be variable and non-specific.

Findings:

• Imaging findings for DFSP are often non-specific.
• Biopsy is essential for accurate diagnosis of dermatofibrosarcoma protuberans.
• This case demonstrates a large DFSP in an uncommon facial location.

Implications:

• Highlights the importance of considering DFSP in differential diagnoses for head and neck masses.
• Emphasizes the need for biopsy in diagnosing cutaneous lesions with variable presentations.
• Contributes to understanding the diverse clinical manifestations of dermatofibrosarcoma protuberans.
