Granulomatous Neutrophilic Cystic Mastitis, Case Report

Descripción del Articulo

Cystic neutrophilic granulomatous mastitis (CNGM) is a recently characterized entity, with specific histopathological details that differentiate it from other types of chronic idiopathic mastitis. The presence of gram-positive bacilli within cystic-like spaces surrounded by neutrophils, in a context...

The presence of gram-positive bacilli within cystic-like spaces surrounded by neutrophils, in a context of suppurative granulomatous inflammation, define this entity. The importance of its recognition in the diagnostic report lies in its association with infection by corynebacterial species, so that treatment with antibiotics can be targeted, beyond the anti-inflammatory treatment that is usually administered to idiopathic mastitis.We describe the case of a 35-year-old female patient with no related history, with intermittent breast pain, associated with the presence of multiple hard, palpable nodules in both breasts, with results from multiple previous private biopsies that described chronic granulomatous mastitis with a tubercular reaction, for which she received treatment for tuberculosis. Despite this, the clinical response was partial. Histological slides were reviewed at the institution and the diagnosis of CNGM was then established.The presentation of this case was considered important due to its low recognition among pathologists, despite presenting characteristics already defined by previous studies.La mastitis granulomatosa neutrofílica quística (MGNQ) es una entidad recientemente caracterizada, con detalles histopatológicos específicos que la diferencian de otros tipos de mastitis crónicas idiopáticas.

La importancia de su reconocimiento en el reporte diagnóstico recae en su asociación a la infección por especies de corinebacterias, de esa manera se puede direccionar el tratamiento con antibióticos, más allá del tratamiento antiinflamatorio que suele administrarse en mastitis idiopáticas.Se describe el caso de una paciente de sexo femenino, de 35 años de edad, sin antecedentes relacionados, con dolor mamario intermitente, asociado a la presencia de múltiples nodulaciones palpables, duras, en ambas mamas, con resultados de múltiples biopsias particulares previas que describieron mastitis crónica granulomatosa con reacción de tipo tuberculoso, por lo cual recibió tratamiento antituberculoso.
