Abstract

Sebaceous glandular hyperplasia (SGH) is a benign form of skin pathology, occurring in approximately one percent of the population. Risk factors for the SGH include advanced age, male sex, exposure to UV radiation and immunosuppression. The pathogenesis of SGH involves hormonal changes, is also regulated by insulin levels, thyroid stimulating hormone (TSH) and cortisol. SGH manifests itself as solitary or multiple light-yellow lumps, 2–3 mm big, with a smooth surface and a central umbilical depression. The vulvar localization of lesions is extremely rare and presents with a polymorphous clinical picture, posing a major diagnostic problem. A 40-year-old patient presented to the clinic due to vulvar skin lesions, periodically with the swelling of the labia and itching, with the symptoms deteriorating for approximately two years. The patient has been consulted by several doctors; however, the diagnosis has not been established. She did not receive adequate treatment either. On physical examination, attention was drawn to the overgrown labia minora — especially on the right side — with a network of abnormal vessels and numerous small papular lesions. SGH was diagnosed, based on the samples collected from the vulva. The patient was recommended isotretinoin therapy and referred to a dermatologist for a consultation. The presented case of vulvar SGH is interesting and rare. It is a diagnostic challenge with no established treatment standards. Nonetheless, SGH should be considered in the differential diagnosis of vulvar skin lesions. The comprehensive and interdisciplinary care is needed to help patients struggling with this insidious condition.
