Abstract
- Collagenomas, or connective tissue nevi of the collagen type, represent a hamartomatous overgrowth of normal collagen. Isolated collagenoma is rare and most commonly presents in childhood. We herein report a rare case of congenital isolated collagenoma on the scalp without any associated abnormality. A 4-year-old boy with normal development presented with 2x1.5 cm sized, soft, dome-shaped brownish nodule on the scalp. Histopathologic study revealed collagen bundles with thickened appearance, a condition consistent with collagenoma.
