Acquired Digital Fibrokeratoma.

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Acquired digital fibrokeratoma is a rare, benign appendageal tumor.
• It commonly presents on fingers and toes, often mimicking a supernumerary digit.
• The etiology is thought to involve trauma, affecting adult males predominantly.

Observation:

• A male patient presented with an acquired digital fibrokeratoma on a finger.
• The lesion exhibited an unusual morphology, resembling a cutaneous horn.
• The patient reported a history of minimal, repeated trauma to the affected digit.

Findings:

• The case describes spontaneous remissions of the fibrokeratoma, a phenomenon not previously documented.
• This presentation challenges typical clinical expectations for acquired digital fibrokeratoma.
• Histopathological analysis confirmed the diagnosis of acquired digital fibrokeratoma.

Implications:

• This case expands the known clinical spectrum of acquired digital fibrokeratoma.
• Understanding atypical presentations and natural course variations is crucial for accurate diagnosis.
• Further research may elucidate the mechanisms behind spontaneous remission in fibrokeratomas.
