Glomus Tumor of the Toe

Area of Science:

• Dermatology
• Oncology
• Pathology

Background:

• Glomus tumors are uncommon benign neoplastic lesions originating from glomus bodies, primarily involved in thermoregulation.
• While most commonly found in the subungual areas of the hand, glomus tumors can occur in various body locations.
• Typical symptoms include pain, pressure sensitivity, and cold intolerance.

Observation:

• This case report details a glomus tumor located in the subcuticular tissue of the second toe, a rare, non-subungual presentation.
• The lesion was situated adjacent to the medial middle phalanx of the affected toe.
• The patient presented with symptoms consistent with a digital soft-tissue lesion.

Findings:

• Surgical excision of the lesion was performed.
• Histopathological examination confirmed the diagnosis of a glomus tumor.
• The tumor's location in the non-subungual toe represents an atypical site for this neoplasm.

Implications:

• This case underscores the necessity of including glomus tumors in the differential diagnosis for digital soft-tissue lesions, even in non-subungual locations.
• Awareness of variant presentations can improve diagnostic accuracy and patient outcomes.
• Further research into the diverse locations and presentations of glomus tumors may refine clinical suspicion and diagnostic protocols.
