Abstract
- Sebaceous hyperplasia (SH) is a benign proliferation of the sebaceous glands. Ultraviolet radiation is known to be the cofactor for the pathogenesis of SH. Frequently reported adverse events of 308-nm excimer laser are erythema, burning or pain, and itching sensation. However, the role of excimer laser as an aetiological factor of SH is rarely reported in the literature. A 59-year-old female presented with several elevated, umbilicated papules on the face. Papular eruption appeared abruptly after 11 weeks of treatment for vitiligo which includes 308-nm excimer laser therapy. The distribution of lesion was associated with the treated area. Total cumulative dose was 3,300 mJ/cm 2 over 16 sessions. Histopathologic findings showed enlarged sebaceous glands composed of numerous lobules around a centrally located, widened sebaceous duct. Chronic sun exposure clinically causes SH was proved in the previous animal studies. Thus, we introduce a rare case of eruptive SH in the patient treated with 308-nm excimer laser.
