Trichoepithelioma Papular Multiple Jarisha

Trichoepitheliomas papular multiple of Jarisha are a rare type of benign skin tumors that are caused by mutations in the genes responsible for the growth and division of epidermal cells. These tumors can develop in different areas of the body, but most often they appear on the face, neck, chest, back and arms.

**Causes of multiple papular trichoepithelioma of Jarisch**

Trichoeptheliomas are associated with a mutation in a gene called “TCHH,” which regulates the growth and differentiation of epidermal cells. Mutation of this gene leads to the development of trichoepitheliomas, which are usually located under the skin and are not visible from the outside. However, with a mutation in the "TCHH" gene, a change in the process of cell division may occur, which
