RESUMO

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.

RESUMO

Small cell lung carcinoma (SCLC) is a cancer that shows aggressive behavior, early spread to distant sites, and frequent association with distinct paraneoplastic syndromes. Spontaneous remission of cancer, particularly of SCLC, is a rare biological event. Cases involving spontaneous regression of SCLC were reported, and were associated with paraneoplastic syndromes of the nervous system. This article reports on a 78-year-old man with SCLC in remission, with neurological symptoms. The patient visited the hospital because of generalized weakness, and imaging studies revealed a mass in the lower lobe of the left lung, pathological evaluation showed SCLC. The patient refused oncologic treatment and was treated only with conservative care. In follow-up study the diameter of the mass had decreased from initial 32 mm, 9 months after admission to 20 mm, 17 months after admission to 13 mm. The patient kept complaining of generalized weakness, dizziness, and paresthesia of limbs. We assumed that, in this case, the spontaneous remission of lung cancer was related to the immunologic response directed against the tumor, which is believed to be an important factor in the pathogenesis of paraneoplastic neurologic syndromes.

RESUMO

The main causes of biliary obstruction are stones and cancers. Fascioliasis is a very rare case which causes biliary obstruction. Fascioliasis is a zoonosis caused by Fasciola hepatica which infects herbivores like sheep and cattle. F. hepatica lives in the biliary system or the liver parenchyma of a host. In Korea, the occurrence of this infection in human is very rare and only few cases have been reported. A 32-year-old male presented with upper abdominal pain and jaundice. His laboratory finding revealed elevated liver transaminases. Abdomen CT scan showed mild left intrahepatic bile duct dilatation. On ERCP, adult F. hepatica worms were found and were thus removed. Concurrently, clonorchiasis was diagnosed by stool exam and serologic enzyme-linked immunosorbent assay test. Clonorchiasis was treated with praziquantel. Herein, we report a case of intrahepatic bile duct dilatation due to F. hepatica infection with concurrent Clonorchis sinensis infestation.
