Deep dermatofibrosarcoma protuberans in a ninety-year old-woman

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Subcutaneous tumors can present diagnostic challenges, especially in elderly patients.
• Accidental trauma can precede the development of certain neoplastic lesions.
• Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing malignant skin tumor.

Observation:

• A 92-year-old female presented with an asymptomatic subcutaneous mass following a fall.
• Clinical and radiological assessments suggested a subcutaneous hematoma.
• The lesion was located in the subcutaneous tissue.

Findings:

• Histological examination revealed the mass to be a subcutaneous dermatofibrosarcoma protuberans.
• The tumor's presentation mimicked benign post-traumatic sequelae.
• Microscopic analysis was crucial for definitive diagnosis.

Implications:

• This case underscores the need for thorough histopathological evaluation of subcutaneous masses, even when they appear benign or trauma-related.
• Awareness of DFSP's potential to mimic other conditions is important for clinicians.
• Early and accurate diagnosis of DFSP is essential for appropriate management and improved patient outcomes.
