We report a case of histoplasmosis capsulati endocarditis simultaneously infecting a mitral and aortic porcine bioprostheses. Histologically, the fungus demonstrated a diversity of morphologies, ranging from typical, intracellular, 2- to 5-micron yeast cells, to septate and branching hyphae, to bizarre hyphae with vesicular swellings. Cultures obtained from both valves were positive in four days. The combination of unexpected histologic appearance and rapid growth in culture may pose problems in diagnosis.
我们报告一例荚膜组织胞浆菌性心内膜炎病例，该病例同时感染了二尖瓣和主动脉瓣的猪生物瓣膜。组织学上，该真菌表现出多种形态，从典型的、2至5微米的细胞内酵母细胞，到有隔膜和分支的菌丝，再到带有囊状肿胀的奇异菌丝。从两个瓣膜获取的培养物在四天内呈阳性。组织学表现意外与培养中快速生长相结合可能会给诊断带来问题。
