What is trichothelioma?

Trichothelioma is a rare type of skin tumor that originates from hair follicle cells. It is classified as a benign neoplasm, meaning it is generally non-cancerous. The tumor typically appears as a nodular lesion on the skin and is most commonly found on the scalp or face. While it is not considered life-threatening, surgical excision is often recommended for cosmetic reasons or if the lesion becomes symptomatic.
