[Pica: nosographical and psychopathological aspects].

The authors, after examining a clinical case of obsessive-compulsive disorder, associated to Pica syndrome, analyse psychopathological development of the symptomatology in its complex, refuting some statements of published studies, that include Pica within obsessive-compulsive disorder spectrum. On the contrary, they think the coexistence of the two symptomatologies simply as an expression of a comorbidity, explaining why they are prone to link Pica with eating disorders.
