Successful Treatment of Long-Standing Dermatillomania With Sertraline in a Rural Mexican Patient: A Case Report and Literature Review.

Dermatillomania (DTM) is a psychodermatosis characterized by the presence of self-inflicted skin lesions due to excessive scratching in the absence of an underlying disease. We present the case of a 57-year-old female from a rural area of Zacatecas, Mexico, with an eight-year history of undiagnosed DTM, who exhibited extensive bilateral lesions on the arms, forearms, knees, and legs, which were successfully treated with sertraline alone. This article highlights the importance of DTM, its clinical presentation, and appropriate treatment to prevent complications.
