REsUMEnRothia mucilaginosa (R. mucilaginosa), antiguamente denominada Stomatococcus mucilaginosus, es un coco Gram positivo capsulado, anaerobio facultativo, que forma parte de la flora orofaríngea normal y raramente se considera patógeno en pacientes inmunocompetentes, aunque puede producir, de forma poco habitual, infecciones graves como bacteriemias, endocarditis e infecciones respiratorias: neumonías, empiemas pleurales o sobreinfección de bronquiectasias.Presentamos el caso de un varón de 74 años diagnosticado de neumonía basal derecha de evolución tór-pida con mala respuesta inicial a diversos antibióticos, con empeoramiento clínico y radiológico y aparición de bronconeumonia bilateral con imágenes pseudonodulares. En 3 cultivos de esputos y en broncoaspirado se aisló R. mucilaginosa en cultivo puro. Finalmente fue tratado con Linezolid con buena respuesta clínica y normalización de la radiografía de tórax, comprobando la desaparición de R. mucilaginosa en posteriores cultivos de esputos.Existen pocos casos documentados de neumonía por R. mucilaginosa por lo que consideramos de interés presentar éste.Palabras clave. Rothia mucilaginosa. Bronconeumonía. Nódulos pulmonares. Linezolid.
aBstRactRothia mucilaginosa (R. mucilaginosa), formerly named Stomatococcus mucilaginosus, is a facultatively anaerobic, encapsulated gram-positive coccus, which forms part of the normal oropharyngeal and is rarely considered to be a pathogen in immunocompetent patients, although it can produce, on rare occasions, serious infections like bacteremia, endocarditis and respiratory infections; such as pneumonia, pleural empyema or superinfection of bronchiectasis.We present the case of a 74-year-old male diagnosed with right basal pneumonia of torpid evolution with poor initial response to different antibiotics, with clinical and radiological worsening and the appearance of bilateral bronchopneumonia with pseudonodular images. R. mucilaginosa in pure culture was isolated in three sputum cultures and in bronchial suction. The patient was finally treated with Linezolid with good clinical response and normalisation of the thorax radiography, confirming the disappearance of R. mucilaginosa in subsequent sputum cultures.As there are few documented cases of pneumonia due to R. mucilaginosa, we believe that presenting this case will be of interest.
Neutrophilic dermatoses encompass a wide spectrum of diseases characterized by a dense infiltration mainly composed of neutrophils. Neutrophilic dermatosis of the dorsal hands is currently considered a localized variant of Sweet syndrome. Cocaine abuse has been related to a wide range of mucocutaneous manifestations, including neutrophilic dermatoses such as pyoderma gangrenosum. The authors of this study present a patient with neutrophilic dermatosis of the dorsal hands, in which cocaine abuse was identified as a probable trigger.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
