Cutaneous horn is the clinical entity, which is circumscribed, conical, markedly hyperkeratotic lesion in which the height of the keratotic mass amounts to at least half of its largest diameter. It may be associated with many different pathological lesions. It is a relatively rare and a kind of epidermal tumor that generally appears as a conical projection. Here, we report rare case of congenital cutaneous horn. A 39-month-old female Korean patient presented at our clinic with a mass at the tip of her nose present since birth. Under general anesthesia, cutaneous horn of nasal tip was completely excised without any complications. The operation site was small enough to perform a primary closure, without any nasal deformity. Histopathologically, it was reported as a fibroepithelial polyps. After operation, there is no evidence of recurrence at 16 months of follow-up.

Phyllodes tumors of the breast are relatively rare fibroepithelial tumors that account for less than 1% of primary breast neoplasms. Phyllodes tumors have epithelial and stromal components and they originate from the periductal stroma. They are classified as benign, borderline, or malignant. Carcinomatous differentiation of the epithelial components of phyllodes tumors is rare, and their imaging features have not been accurately described. Herein, we report a rare case of invasive ductal carcinoma originating from a borderline phyllodes tumor in a 21-yearold female with radiologic and pathologic findings.
