Abstract

Purpose: Collagenoma is an intradermal harmatomatous collagen proliferation among connective tissue nevi of the skin. Although there are some reports of isolated collagenomas that occurred on the sole and the palm, collagenoms at the finger has not been reported in Korea. Methods: An 11-year-old girl presented with a growing mass on the distal interphalangeal joint of the left 5th finger. It was a skin-colored, oval and mild tender mass. There were no associated cutaneous or systemic abnormal findings. Results: The nodule, at the subcutaneous level on the distal phalanx, was completely removed by excision. Grossly it was covered with normal skin, and its surface was smooth having a definite margin with a size of $1.5{\times}1.2cm$. Histopathological examination, the epidermis showed to be normal, increased thickness of collagens arranged with a whirl formation was found in the dermis. No signs of cellular component increase were observed. Conclusion: Isolated collagenoma can be aroused as a solitary nodule in at any place of the body. We report a rare case of a female patient with an isolated finger collagenoma.
