title: Small primary cutaneous mucinous carcinoma mimicking an early basal cell carcinoma.
abstract: We report an early case of primary cutaneous mucinous carcinoma in a male patient with chronic actinic damage. Dermoscopic features influenced the clinical decision to obtain tissue for histopathology, which in turn revealed characteristic strands and nests amidst mucinous stroma. Immunohistochemistry did not confirm cutaneous origin of the tumor; instead a full internal malignancy screen was required. Clinicians should be aware of this rare entity, which most commonly occurs on the head and neck, and give advice on appropriate further investigations and management.
