Giant Dermatofibroma: A Rare Presentation as a Large Scaly Plaque

Area of Science:

• Dermatology
• Pathology

Background:

• Dermatofibroma (DF) is a common skin neoplasm.
• Giant dermatofibroma is a rare variant, posing diagnostic challenges due to its size and potential to resemble malignant tumors.

Observation:

• A case of giant dermatofibroma is presented in a 29-year-old male.
• The lesion was a 7 cm, nonulcerated, pink-brown plaque on the leg.

Findings:

• This case adds to the limited literature, with fewer than 30 previously reported instances of giant dermatofibroma.
• The distinct presentation can lead to diagnostic uncertainty requiring clinicopathologic correlation.

Implications:

• Increased awareness of giant dermatofibroma is crucial for clinicians.
• Familiarity with this rare DF variant can prevent unnecessary interventions and diagnostic delays for this benign skin condition.
