A Case of Isolated Collagenoma / 대한피부과학회지

ABSTRACT

Collagenomas are considered to be connective tissue nevi composed predominantly of collagen. They can be hereditary or sporadic. We report herein a rare case of isolated collagenoma on the left side of the face and the left thigh without associated abnormalities, in a 30-year-old man. Histopathologically, the lesion consisted of thick collagen fibers, which was compatible with collagenoma.
