Aplastic anemia is a rare complication of thymoma and is extremely infrequent after thymectomy. We present a case of a 60-year-old woman with very severe aplastic anemia appearing sixteen months after thymectomy for a thymoma. She underwent thymectomy for a thymoma in April 2000. Preoperative examination revealed no hematologic abnormality. About sixteen(More)
Eschar is an important finding for the diagnosis of scrub typhus. The IFA test for possible scrub typhus was performed. The presence or absence of eschar was thoroughly examined. Among the 176 scrub typhus cases confirmed by IFA, 162 (92.0%) cases had eschar; 128 patients (79.5%) had eschars on the front of the body. Eschars were primarily detected in males(More)
Behçet’s disease (BD) is a systemic inflammatory disorder of unknown etiology, and rarely complicated with myelodysplastic syndrome (MDS). In the present study, we investigated the morphological myelodysplasia and apoptotic rate of bone marrow cells in 15 patients with BD in comparison with MDS patients. Morphological myelodysplasia of bone marrow cells was(More)
We describe a scrub typhus patient with acute renal failure for whom a diagnosis was made based on serology as well as immunohistochemical (IHC) staining and an electron microscopic examination (EM) of a renal biopsy specimen. For our case, we demonstrated by IHC staining and EM that renal failure was caused by acute tubular necrosis due to a direct(More)
Chronic eosinophilic leukemia (CEL) is a rare hematologic malignancy difficult to distinguish from hypereosinophilic syndrome (HES). If a clonal cytogenetic abnormality is detected, then it is diagnostic of CEL [1]. We report the first case of a patient with CEL with 46,XY,1,der(1;7) (q10;p10) translocation. A 58-year-old Korean man had already been treated(More)
BACKGROUND The aim of this study was to determine the diagnostic utility of performing eschar polymerase chain reaction (PCR) for the diagnosis of scrub typhus through a prospective comparison of eschar PCR results with indirect immunofluorescent antibody assay (IFA) results. METHODS We conducted a multicenter prospective study involving patients with(More)
Up to 5% of all small cell carcinomas develop at extrapulmonary sites. Primary small cell carcinomas originating in the kidney are extremely rare neoplasms. Here we report a case of primary small cell carcinoma of the kidney. A nephrectomy was performed on a 52-year-old female patient to remove a large tumor located in the right kidney. The histology and(More)
BACKGROUND The purpose of this study was to evaluate whether measuring the ratio of descending aortic enhancement (DAE) to main pulmonary artery enhancement (MPAE) on pulmonary computed tomography angiography (PCTA) can predict poor outcome in patients with acute massive or submassive pulmonary embolism (PE). METHODS We retrospectively, reviewed computed(More)
BACKGROUND/AIMS Colonoscopic perforations have been managed with exploratory laparotomy, and have resulted in some morbidity and mortality. Recently, laparoscopic surgery is commonly performed for this purpose. The aim of this study was to compare the outcomes of several management strategies for iatrogenic colonoscopic perforations. METHODS We(More)
We experienced a fatal case caused by Brucella abortus with multifocal necrosis confirmed by culture and polymerase chain reaction. Our case highlights that the clinician should be aware of the potential for fatality when a patient with brucellosis shows dissemination of abscess or nodules with no calcification in the liver, lung, pleura, and spine.
