Exophytic Nodule on the Finger

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Myopericytoma is a rare, benign neoplasm originating from perivascular cells.
• These tumors commonly occur on the extremities but can arise anywhere.
• They typically present as asymptomatic, dome-shaped, non-exophytic lesions.

Observation:

• A 45-year-old female presented with an atypical exophytic digital myopericytoma.
• The lesion was located on the digit, deviating from the usual non-exophytic presentation.
• The patient experienced a benign disease course.

Findings:

• The case demonstrates an unusual exophytic growth pattern of myopericytoma.
• Local punch excision was an effective treatment modality for this digital lesion.
• Histopathological confirmation of myopericytoma was established.

Implications:

• This case expands the spectrum of clinical presentations for myopericytoma.
• Highlights the importance of considering atypical presentations in diagnosis.
• Suggests local excision as a viable treatment for exophytic digital myopericytomas.
