作者报道口腔组织胞浆菌病1例,这种地方性呼吸道真菌病在美国极为常见,它是由荚膜组织胞浆菌感染所致。组织胞浆菌病具非传染性,且有自限性,但在免疫减弱患者可能发生再感染和散在性感染。本文所报道的患者带有HIV,但没有系统性病症的迹象。该例患者因舌尖一蔓延到口底6月余的溃疡而就诊,患者病史显示其HIV血清学阳性,但未被诊断为爱滋病(AIDS)。 The authors report 1 case of oral histoplasmosis, a endemic respiratory mycosis that is extremely common in the United States and is caused by capsular histoplasmosis. Histoplasmosis is non-contagious and self-limiting, but re-infection and interspersonal infections may occur in immunocompromised patients. The patients reported here carry HIV, but no signs of a systemic disorder. The patient presented with a ulcer that had spread to the bottom of the mouth more than six months after her tongue was covered. The patient's history showed HIV seropositivity but was not diagnosed with AIDS.
