RESUMEN Objetivo. Describir los datos sociodemográficos, manifestaciones clínicas y tratamiento en pacientes diagnosticados con mastitis no puerperal. Métodos. Estudio descriptivo, retrospectivo de una base de registros médicos institucional, entre el 1 enero de 2016 y el 31 diciembre de 2019. Se recopilaron las variables demográficas, clínicas y de tratamiento, que fueron analizadas utilizando estadística descriptiva. Resultados. La prevalencia de mastitis no puerperal fue 3,8%. Todos los casos se presentaron en mujeres de raza mestiza, con edad media al diagnóstico de 40,4 años. El motivo de consulta más frecuente fue por cambios inflamatorios mamarios en 84,8% (n= 28), seguido por presencia de masa en 12,1% (n= 4). El 33,3% (n= 11) de casos tuvo asociación con tabaquismo. El 97% recibió antibióticos como tratamiento inicial (n= 32) y en 7 casos (21,2%) se realizó drenaje ecoguiado; ningún caso tuvo drenaje por mastotomía y en una paciente (9%) se efectuó resección tipo cuadrantectomía.

Casi siempre se resolvió la mastitis con manejo antibiótico y en algunas con drenaje ecoguiado. Hasta un tercio de los casos mostró asociación con tabaquismo. Palabras clave. Mama, Mastitis, Absceso. INTRODUCTION There are many classifications of mastitis. The best known divides it into infectious (puerperal) and non-infectious (granulomatous mastitis). Ac- cording to the time of clinical presentation, it is considered acute and chronic(1). This article is aimed at mastitis not associated with lactation, a rare disorder, with a prevalence of 1 to 2%(2). Lactiferous duct ectasia plays a part in the etiopathogenesis, and is associated with periductal mastitis with dilatation of the lactiferous ducts, occurring in 5 to 9% of non-lactating women(3). Although several cases of non-puerperal mastitis and subareolar ab- scess were described in the late 1800s, it is Zuska and her colleagues who are credited with knowledge of the disease(4).
