Pioderma gangrenoso post-quirúrgico: reporte de un caso en paciente con fibrosis retroperitoneal / Postoperative pyoderma gangrenosum: a case report of a patient with retroperitoneal fibrosis

RESUMEN

El pioderma gangrenoso (PG), es una patología ulcerativa infrecuente de etiología desconocida, asociado ocasionalmente a enfermedades autoinmunes. Es una condición crónica, de curso clínico impredecible y puede ser invalidante. Al ser complejo su diagnóstico, el retraso del mismo puede ocasionar al paciente morbilidades añadidas, como tratamientos incorrectos y períodos de hospitalizaciones prolongados. Se presenta el caso de un paciente de 52 años, sin antecedentes mórbidos, que ingresa a Urgencias en el Hospital el Pino, por dolor abdominal recurrente. Durante el estudio de imágenes se evidencia una masa retroperitoneal, asociada a hidro-uretero-nefrosis izquierda. Ingresa al Servicio de Cirugía para estudio, realizándose una laparotomía media exploratoria y toma de muestras para biopsia. Procedimiento realizado sin incidentes. El paciente pese a múltiples tratamientos otorgados en esa unidad, evoluciona con dehiscencia de suturas recurrentes por tres meses. Evaluado por Dermatología se inicia estudio y se diagnostica PG, teniendo una excelente respuesta al tratamiento indicado.

ABSTRACT

Gangrenous pioderma (PG) is an uncommon ulcerative pathology of unknown etiology associated with autoimmune diseases. It is a non-predictable chronic condition, that can be incapacitating and patients that suffer this disease can also present systemic compromise. As it is a diagnosed by exclusion it may lead to long periods of failed treatments. The present work deals with a case of a 52-year-old male patient with no prior record of disease, who was admitted to the ER of El Pino Hospital suffering from recurrent abdominal pain. During the imaging study a retroperitoneal mass was found, associated with a left hydro-uretero-nephrosis. He was admitted and a exploratory mid-laparotomy was performed and samples were taken for biopsy. The procedure was successful and the established protocol was followed. However, during the recovery period the patient developed repeated surgical wound dehiscences of the surgical wounds. An internal consultation with the Dermatology Service took place, and the diagnosis of PG was made; proper pharmaceutical treatment was provided attaining excellent results.
