Linear and dermatomal trichoepitheliomas.
A 10-year-old black girl presented with multiple trichoepitheliomas. They appeared at an early age and were grouped on her neck. Later they also involved her face, trunk, and lower extremity in a dermatomal distribution. The lower extremity showed a narrow linear band extending from the ankle to the upper portion of the thigh. To the best of our knowledge, this is the first case of linear and dermatomal trichoepitheliomas. We therefore present this case and review the literature.
