Pyoderma gangrenosum: a rare disease with a rare localization

Abstract

Pyoderma gangrenosum (PG) is a rare neutrophilic inflammatory disease, characterized by necrotizing and painful ulcers of unknown cause, that it is often misinterpreted. PG is usually idiopathic and includes dysregulation of the autoimmune system and frequently has an association with other systemic diseases (inflammatory bowel disease, rheumatological, hematological disease or malignancy). The most common localization is on the lower legs, mainly in the pretibial area. We describe a case of Pyoderma gangrenosum in a 43 year-old female patient with erythemato-edematous big plaque, covered with sphacelous, yellow-green pus, localized on the left inguinal area and pubic area, which is a rare localization of this disease.
