[Solitary subungual glomangioma]

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Glomangiomas are typically multiple, painless, and extradigital benign vascular tumors.
• Subungual glomangiomas are rare, presenting a diagnostic challenge.
• Understanding vascular glomus tumors is essential for accurate diagnosis.

Observation:

• A solitary subungual glomangioma was observed in a 65-year-old woman.
• The lesion presented as a bluish, asymptomatic tumor in the lunula of the thumb.
• Surgical excision and histological examination confirmed the diagnosis.

Findings:

• Histopathology revealed numerous dilated blood vessels with aggregates of glomus cells.
• The tumor was a well-circumscribed, bluish mass.
• Diagnosis of glomangioma was confirmed through histological examination.

Implications:

• Solitary subungual glomangiomas require differentiation from melanocytic tumors.
• Histological examination is vital for definitive diagnosis.
• This case highlights the varied presentation of glomus tumors.
