Coccidioidomycosis is a predominantly pulmonary disease caused by species of Coccidioides, a fungus endemic to the American Southwest. Most cases involve exclusively pulmonary manifestations while less than one percent present with disseminated infection, usually with meningeal or skin involvement. In this case, a patient with a history of odynophagia, sore throat, productive cough, weight loss, and abnormalities on chest radiograph presented with sepsis and diabetic ketoacidosis. During admission, the patient underwent bronchoscopy with resulting tissue and bronchoalveolar lavage samples positive for Coccidioides immitis, later supported by confirmatory serum studies. This case illustrates a rare presentation of vocal fold involvement without direct invasion from a continuous site and highlights the importance of a high index of suspicion for disseminated coccidioidomycosis with prompt antifungal treatment in order to avoid the very high morbidity and mortality in such cases.

Hypervirulent Klebsiella pneumoniae (HV-KP) typically causes pyogenic liver abscess and bacteremia with metastatic infections. Community-acquired pneumonia (CAP) due to HV-KP is uncommon and details of its clinical and microbiological features are limited. We report the first case of CAP due to capsular genotype K2-ST86 HV-KP in Okinawa, Japan and review infections caused by the K2-ST86 strain. A 79-year-old woman presenting with fever and productive cough persisting for the past three days was admitted to hospital. Her vital signs indicated septic shock. Lung examination by auscultation revealed holo-crackle and lobar pneumonia in chest radiography, and Streptococcus pneumoniae was suspected. However, sputum and blood cultures revealed Gram-negative coccus identified as K. pneumoniae. Genetic analysis identified the isolated strain as the K2 serotype harboring rmpA, iutA, entB, and mrkD. Therefore, we identified the isolated strain as hypervirulent. The isolate belonged to ST86 as determined by multilocus sequence typing. The case was not complicated by predisposing factors such as diabetes mellitus and malignancy related to HV-KP infection; thus, this CAP-causing HV-KP strain may differ from the typical HV-KP strain that induces liver abscess. A literature review identified only nine cases with CAP due to HV-KP. In all cases, the disease mainly occurred in older males with diabetes mellitus, which makes the present case unusual, and had high rates of septic shock and death. No case, including ours, was complicated by metastatic infection, suggesting that CAP due to HV-KP poses little distant metastasis risk, even in patients with bloodstream infection. In our review, consistent with our case, K2-ST86 was the most common strain of HV-KP in patients with CAP. Therefore, studies are needed to elucidate the clinical and microbiological features of HV-KP CAP, with a focus on the K2-ST86 strain. Physicians should always consider K. pneumoniae in cases of sepsis CAP with lobar pneumonia.
