Primary mucinous carcinoma of the skin is a rare skin adnexal neoplasm with sweat gland differentiation. There have been only few cases of it reported in literature. It is a low grade malignant tumor arising preferentially in the head and neck and periorbital area. We report a case of primary cutaneous eccrine mucinous carcinoma in a 75-year-old male presenting with a swelling in the lateral angle of his right eye.
