%X La necrosis grasa del reci¨¦n nacido (NGRN) es una rara enfermedad que afecta al tejido adiposo y que se desarrolla durante las primeras semanas de vida. Se caracteriza por nodulos y/o placas eritemato-viol¨¢ceas, de consistencia duro-el¨¢stica, ¨²nicas o m¨²ltiples, en dorso, hombros, gl¨²teos, brazos, muslos y mejillas, que evolucionan espont¨¢neamente hacia la regresi¨®n. Si bien pueden desarrollarse complicaciones, ¨¦stas son infrecuentes, siendo la m¨¢s importante la hipercalcemia. La patogenia de la NGRN es desconocida, aunque se han identificado factores predisponentes para su desarrollo. Presentamos el caso de un reci¨¦n nacido de pret¨¦rmino de 36 semanas, sexo masculino, que present¨® un cuadro cl¨ªnico compatible con NGRN. El diagn¨®stico se sospech¨® en base a la cl¨ªnica, a los antecedentes perinatales y se confirm¨® con el estudio histopatol¨®gico. El paciente evolucion¨® satisfactoriamente con regresi¨®n de las lesiones y sin presentar complicaciones hasta la fecha. Newborn fat necrosis is an unfrequent disease that compromises the adipose tissue and develops during the first weeks of life. It is characterized by reddish-purple nodules and/or plaques with a hard elastic consistency, isolated or m¨²ltiple, localized at the back, shoulders, buttocks, arms, thighs and chin. They evolve spontaneously to regression and unfrequently develop complications, being hypercalcemia the most observed. The pathogenesis of newborn fat necrosis is unknown, although certain risk factors for its development have been identified. Case-report: A 36 weeks preterm male newborn with a clinical picture compatible with fat necrosis. The diagnosis was made according to the clinical findings and his perinatal history, confirming it with pathology. The patient evolution was complete improvement and regression of the lesions, without complications.
