Dermal duct tumors are uncommon and mostly benign. It manifests clinically as a firm papule, plaque, or nodule, most commonly on the lower limbs or the head and neck region. Dermal duct tumors are classified as poromas. These tumors can have divergent differentiation, but prominent ductal and sebaceous differentiation is a rare entity. Here we present a right thigh dermal duct tumor with prominent ductal differentiation. A 63-year-old man presented with a 2-year-old painless, slow-growing papilloma-like lesion over the upper anterior part of the right thigh. As no definitive opinion could be made on fine needle aspiration, an excision biopsy was done and diagnosis was confirmed through histopathology.
