Abstract:
Collagenoma is a hamartomatous lesion consisting of proliferation of normal collagen tissue. We describe a 19-year-old girl with a firm, elastic 3 x 2 cm nodule located on her right plantar fossa. Histopathologically, dense, coarse, thick collagen fibers were located in the dermis. In addition, the number of elastic fibers was slightly decreased. Based on these findings, the case was diagnosed as isolated plantar collagenoma.
