Achromobacter xylosoxidans is a gram-negative bacterium that can oxidize xylose. It is commonly found in contaminated soil and water but does not normally infect immunocompetent humans. We report a case of a cavitary lung lesion associated with community-acquired A. xylosoxidans infection, which mimicked pulmonary tuberculosis or lung cancer in an immunocompetent man. The patient was hospitalized due to hemoptysis, and chest computed tomography (CT) revealed a cavitary lesion in the superior segment of the left lower lobe. We performed bronchoscopy and bronchial washing, and subsequent bacterial cultures excluded pulmonary tuberculosis and identified A. xylosoxidans. We performed antibiotic sensitivity testing and treated the patient with a 6-week course of amoxicillin/clavulanate. After 2 months, follow-up chest CT revealed complete resolution of the cavitary lesion.

Abstract PDF: Pleuropulmonary diseases caused by Clostridial species infections are rare, but have a mortality rate of up to 30%. Furthermore, older people are at greater risk of developing invasive clostridium infections, and the majority of reported cases of clostridium empyema have been attributed to iatrogenic trauma or aspiration. The authors report a case of spontaneous empyema caused by Clostridium perfringens. A 72-year-old woman was admitted to Kangwon National University Hospital for empyema. The patient had no history of trauma, a dental procedure, or aspiration, and was treated using empirical antibiotics and by drainage of pleural fluid. Bacteria species that cause empyema are usually not detected, but on the 4th day of admission, C. perfringens was isolated from the pleural space. The patient was continuously treated with antibiotics for C. perfringens and drainage, and was discharged 25 days after admission with almost a fully recovered status. Increased awareness of Clostrium species infection in the elderly is needed to ensure appropriate treatment.

Abstract PDF: Cases of coexistent lichen sclerosus et artrophicus and morphea have been reported. It is controversial that both diseases are single disease-spectrum or entirely separated. We encounterd a forty five year old female with a hypopigmented firm plaque on the left neck. Its histologic feature showed compact orthokeratosis, follicular plugging, atrophy of the stratum malpighii with vacuolar alteration of basal layer, and homogenization of the collagen in the upper dermis (lichen sclerosus et atrophicus). Increased thick collagen bundles were seen in the lower dermis (morphea).
