Large Eccrine Acrospiroma of the Hand.

Area of Science:

• Dermatology
• Surgical Pathology
• Oncology

Background:

• Eccrine acrospiromas are benign skin neoplasms originating from sweat duct epithelium.
• They typically present as small, solid, or cystic lesions, often misdiagnosed clinically.
• Malignant transformation is rare but documented.

Observation:

• A middle-aged female presented with a large swelling on the dorsum of her left first web space.
• Clinical presentation mimicked other common solid or cystic lesions of the hand.
• Histopathological examination confirmed the diagnosis of eccrine acrospiroma.

Findings:

• The lesion was confirmed as an eccrine acrospiroma, notable for its unusually large size.
• Surgical excision was performed for definitive management.
• Reconstruction of the defect was achieved using a regional flap.

Implications:

• This case underscores the importance of considering eccrine acrospiroma in the differential diagnosis of hand swellings, regardless of size.
• Large eccrine acrospiromas require surgical management, potentially involving reconstructive techniques.
• Further research into the factors influencing the size and malignant potential of eccrine acrospiromas may be warranted.
