 en Trichosporon mucoides check for this species in other resources infection in an immunocompetent host
García, Lucy & Osorio, Guiovana Fernanda

Abstract

A forty-year-old woman, hairdresser, presented a month history of progressive necrosis of the left fourth finger nailbed, accompanied by intense pain, without pathological antecedents and no trauma. Histologic examination showed extensive surface necrosis with abundant cell detritus and erythrocytes, within the necrotic tissue displacing the collagen. There were hyaline, birrefringent structures compatible with arthroconidia Tissue culture for aerobic as well as anaerobic bacteria and mycobacteria were negative. In tissue culture for fungus grew Trichosporon mucoides. A fluconazole therapy was initiated with 400 mg per week dosage, with clinical improvement. This fungus also normal soil inhabitant, is characterized by the presence of true hyphae, other members of the genus have pseudohyphae, arthroconidia y blastoconidia. T. mucoides can also be an opportunistic pathogen producing potentially fatal systemic infections in immunocompromised hosts. Cases of onychomycoses with this fungus as causative organism have been reported, but their symptomatology has not been as severe as in this case.

 es Trichosporon mucoides check for this species in other resources infeccion en paciente inmunocompetente

Resumen

Mujer de 40 años, con historia de un mes de evolución de necrosis progresiva del lecho ungueal del cuarto dedo de la mano derecha, con dolor intenso y destrucción de la placa ungueal. Sin antecedentes patológicos, ni traumáticos. En la biopsia se observaron estructuras micóticas y en los cultivos para hongos se obtuvo crecimiento de Trichosporon mucoides, confirmado mediante pruebas bioquímicas. Se inició fluconazol y se obtuvo resolución del cuadro. Estos hongos son habitantes normales del suelo y se caracterizan por la presencia de hifas verdaderas, pseudohifas, artroconidias y blastoconidas. T. mucoides puede comportarse como un patógeno oportunista que produce infecciones graves en huéspedes inmunocomprometidos. Se conocen casos aislados de T. mucoides como agente causal de onicomicosis pero ninguno con la severidad del caso que aquí se presenta.

Palabras-clave
Onicomicosis; Trichosporon mucoides; Trichosporon spp.
