[Partial priapisms. Proximal priapism. Report of a case]

A very rare form of priapism in which the disorder is located in a localized area of the erectile tissue of the penis is presented. We consider this to be the first in Spanish literature and the fifth in the world. According to the review carried out, the most frequent etiology is traumatic, although the history of some cases is vague. Attention is drawn to the diagnosis, and therapy, which was successful in every case.
