Multiple Eccrine Hydrocystoma Masquerading as Papular Sarcoidosis in a Patient Suffering from Systemic Sarcoidosis

Sir, Hydrocystomas are rare, benign, cystic skin tumors arising from mature, deformed sweat units which are dilated by their own secretions.[1] Depending on the gland of origin, they can either be apocrine or eccrine hydrocystomas. Eccrine hydrocystoma can either be solitary or multiple. Most commonly they affect the face and neck regions of middle-aged female patients and are often multiple.[1] When on the face, multiple eccrine hydrocystomas can resemble a vast array of papulocystic lesions; papular sarcoidosis being one of them. Here, we present a case of multiple papular and cystic facial lesions in a middle-aged male patient, who is also suffering from sarcoidosis. The papular lesions were being treated in vain as sarcoidosis, because of this association; until histopathological examination (HPE) clinched the diagnosis of multiple eccrine hydrocystoma.
