Steatocystoma multiplex suppurativum: Oral isotretinoin treatment combined with cryotherapy

SUMMARY A 30‐year‐old man presented with numerous papules, nodules and inflamed cysts. The lesions were located all over the body, including the scalp, except the palms and soles. His mother and one sister had had similar but less extensive lesions. Histopathology of the biopsy specimens obtained from the anterior chest wall, axillae and the back region was consistent with steatocystoma multiplex (SM). A diagnosis of steatocystoma multiplex suppurativum was made. The inflamed lesions were treated with oral isotretinoin (1 mg/kg per daily) for 6 months. At the same time, cryotherapy was used for non‐suppurating lesions smaller than 2 cm. When the patient was evaluated 6 months later, cosmetic results were good. No new lesions have appeared in the subsequent 12‐month follow up.
