Primary mucinous carcinoma of the skin (PMCS) is an extremely uncommon skin cancer originating from sweat glands. We present a case of a male patient diagnosed with PMCS who was initially misdiagnosed with benign sebaceous cysts. A 62-year-old male patient presented to a private clinic with a chief complaint of a slowly progressing nodule located under his lower lip for the past two years; The nodule was locally excised . The histopathology analysis yielded a diagnosis of mucinous carcinoma with a positive circumferential margin. Reexcison was performed, and the final histopathology result was a small nest of mucinous carcinoma with a negative surgical margin.
