Eyelid pilomatricomas in young adults: a report of 8 cases.

Pilomatricomas are common benign childhood tumors, which usually occur in the head and neck region. We present 8 patients and review the clinical and histopathologic features of pilomatricoma of the eyelids and eyebrows in young adults. From 1992 to 2000, diagnosis of eyelid pilomatricoma was performed in 8 young adults (13-36 years). The female-male ratio was 3:1. The mean age at presentation was 22 years. Each of our 8 patients had a single tumor, 4 on the upper eyelid and 4 on the eyebrow. Ossification existed in 4 cases. No tumor recurrence has been noted at 3.9 years. Pilomatricomas are uncommon tumors on the eyelid and brow region of young adults. These lesions are frequently misdiagnosed when evaluation is based on clinical evidence alone: only 4 of our cases were correctly diagnosed prior to excisional biopsy.
