INTRODUCTION
Syringomas are benign adnexal tumors originating from the eccrine sweat gland ducts.1 Syringomas are traditionally classified into four subtypes: localized, generalized, familial, and Down syndrome-associated.2 Eruptive syringomas fall under the generalized subtype of syringomas.2 Eruptive syringoma classically develops during puberty or childhood, predominantly in females, and typically localizes to the chest, neck, and upper abdomen.1,3 Lesions are often stable and benign, although there have been some instances of spontaneous resolution.3,4 Herein, we highlight an atypical case of eruptive syringoma occurring in a patient with a darker skin tone, adding to the dermatologic understanding of skin conditions in individuals with skin of color.
CASE DESCRIPTION
A 20-year-old African American female (Fitzpatrick skin type V) presented with dark skin lesions on her chest, abdomen, and bilateral upper and lower extremities. The lesions have been present for 15 years and are asymptomatic, with no associated pain or pruritus. The patient denies the development of new lesions over the years. However, the lesions have been progressively darkening. The patient's maternal aunt had similar lesions that resolved without intervention at 26 years old.
The patient's past medical history was significant for asthma but otherwise unremarkable. She had no history of Down syndrome or any relevant dermatologic conditions. No personal or family history of skin cancer.
Physical examination revealed scattered light to dark brown papules and plaques on the chest, abdomen, and flexure surfaces of the upper extremities greater than the extensor surfaces of the upper extremities and anterior thighs. Lesions were most concentrated and pigmented on the extremities, gradually diminishing in density and intensity towards the central body. No lesions were noted on her face, neck, palms, and soles. No nail changes were noted, and oral mucosa was clear on the exam (Figures 1-3). Due to the patient's distribution
