Eccrine spiradenoma of the ear: case report

Area of Science:

• Dermatology
• Surgical Pathology

Background:

• Eccrine spiradenomas are rare benign skin neoplasms originating from sweat gland ducts.
• While typically found on the trunk and proximal extremities, their occurrence on the head and neck is less common.

Observation:

• A unique case of eccrine spiradenoma located on the left pinna is presented.
• This represents the first documented instance of this tumor at this specific anatomical site.

Findings:

• The eccrine spiradenoma was successfully treated with surgical excision.
• Histopathological confirmation of the benign nature of the tumor was achieved.

Implications:

• This case expands the known anatomical distribution of eccrine spiradenomas.
• Clinicians should consider eccrine spiradenoma in the differential diagnosis of head and neck soft tissue lesions.
