Plaque-Like Dermatofibroma: Case Report of a Rare Entity

Area of Science:

• Dermatopathology
• Oncology

Background:

• Dermatofibromas are common benign skin neoplasms.
• Plaque-like variants are infrequently reported.
• Distinguishing these from other fibrous tumors is clinically important.

Observation:

• A solitary, well-demarcated plaque measuring 11 cm was observed.
• The lesion had been present for several years without satellite lesions.
• Histologic examination revealed classic features of dermatofibroma.

Findings:

• The diagnosis of plaque-like dermatofibroma was established based on histological findings.
• The case highlights the spectrum of dermatofibroma presentations.
• Differential diagnostic considerations included multiple clustered dermatofibromas and plaque-like myofibroblastic tumors.

Implications:

• This case expands the understanding of dermatofibroma morphology.
• Accurate diagnosis is crucial for appropriate patient management.
• Further research may clarify the relationship between different dermatofibroma subtypes.
