Angioleiomyoma of the pulp

Area of Science:

• Dermatopathology
• Surgical Pathology
• Oncology

Background:

• Vascular leiomyomas (angioleiomyomas) are benign, solitary smooth muscle neoplasms.
• These tumors typically arise in the dermis or subcutis, with a predilection for the lower extremities.
• Occurrence in the distal finger, particularly the pulp, is exceptionally rare.

Observation:

• A 64-year-old male presented with a lesion on the pulp of his middle finger.
• The clinical presentation was noted as uncommon for this anatomical location.
• The lesion was identified as a vascular leiomyoma.

Findings:

• Histopathological examination confirmed the diagnosis of vascular leiomyoma.
• The tumor exhibited characteristic smooth muscle and vascular components.
• The distal finger pulp represents an unusual site of origin for this benign tumor.

Implications:

• This case highlights the importance of considering rare differential diagnoses for finger lesions.
• Understanding the varied presentations of vascular leiomyomas is crucial for accurate diagnosis.
• Further investigation into the specific etiology or predisposition for digital angioleiomyomas may be warranted.
