The giant apocrine hidrocystoma.

Area of Science:

• Dermatology
• Surgical Pathology

Background:

• Apocrine hidrocystomas are benign cystic tumors arising from apocrine sweat glands.
• They typically present as small, translucent papules or nodules, usually under 10 mm in diameter.
• These lesions are most commonly found on the face, particularly around the eyelids and forehead.

Observation:

• A case report of a 40-year-old male patient presenting with an unusually large apocrine hidrocystoma.
• The tumor measured 20 mm in diameter, significantly exceeding the typical size range.
• The lesion was located on the face, necessitating evaluation as a large cystic lesion.

Findings:

• The patient had a large apocrine hidrocystoma measuring 20 mm.
• This represents a rare presentation due to the tumor's significant size.
• Histopathological confirmation would be essential for definitive diagnosis.

Implications:

• Apocrine hidrocystoma should be included in the differential diagnosis for large facial cystic lesions.
• The surgical management for this large lesion is comparable to other benign cystic lesions in the facial region.
• This case highlights the importance of considering variations in size for common dermatological conditions.
