The literature describes several dermatological conditions that are not caused by external agents but result from the complex interaction between the brain and the skin. This interaction gives rise to a variety of dermatological lesions, which can be broadly classified into two major categories: psychogenic dermatoses and psychosomatic dermatoses. In this article, we present three cases of Psychodermatosis to illustrate a proposed detailed classification based on the underlying mechanisms and clinical manifestations of these conditions. The cases include: (1) crusty, greasy, brownish facial lesions; (2) excoriated lesions with post-inflammatory hypopigmentation, alopecia, and fractured hairs—characteristic of trichotillomania; and (3) lichenified plaques on the dorsum of the feet, leaving hyperpigmented and atrophic hypopigmented scars, typical of factitious dermatitis. We propose a refined dermatological classification of Psychodermatosis, encompassing two primary categories: (1) cutaneous diseases associated with psychiatric disorders and (2) psychiatric conditions linked to specific cutaneous disorders known to be influenced by psychosomatic factors.
