Complete situs inversus is a rare abnormality of autosomal recessive inheritance; it requires particular care during surgery, because the viscus anatomy is a mirror image of the normal anatomy. Reports of surgery for lung cancer in cases of complete situs inversus are very rare. Here, we report a case of lobectomy for lung cancer of the right lower lobe(More)
We here report a rare case of a patient with IgD-lambda-positive multiple myeloma presenting with FDG-PET/CT negative bone marrow involvement. A 72-year-old man was admitted to our hospital for evaluation of a paravertebral tumor of the chest. Thoracotomy was performed and a histopathological evaluation of resected intrathoracic tumor demonstrated a(More)
Pyothorax-associated lymphoma (PAL) is a representative form of diffuse large B-cell lymphoma associated with chronic inflammation, in which the Epstein-Barr virus (EBV) genome is consistently detectable in the lymphoma cells of all PAL cases. Cell lines and animal models would be useful for understanding better this rare lymphoma, but reports of(More)
An 83-year-old woman was admitted to our hospital with abdominal pain. Examination revealed mediastinal lymphoadenopathy, hepatosplenomegaly, and infiltration of abnormal cells into the bone marrow with hemophagocytosis, and CD5-positive diffuse large B cell lymphoma was diagnosed. Chemotherapy was administered and progressive weakness of the limbs,(More)
We describe a patient with acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) that clinically resembled acute promyelocytic leukemia (APL). The karyotype of his leukemic cells was 46, XY, del (3) (q?) and did not include a chromosomal translocation involving the retinoic acid receptor-α gene. However, retinoic acid syndrome developed, and(More)
Primary bone lymphoma and primary adrenal lymphoma are rare clinicopathological entities of non-Hodgkin's lymphoma (NHL). We present the first case of diffuse large B-cell lymphoma with the involvement of a single bone and both adrenal glands alone with adrenal insufficiency. As primary extranodal NHL may have other unusual extranodal lesions, which may(More)
BACKGROUND Early postpartum women are more likely to develop tuberculosis than nonpregnant women mainly due to immune reconstitution after delivery. Paradoxical response (PR) during antituberculosis treatment also arises via recovery from immunosuppression. However, no study focused on PR during antituberculosis treatment in a postpartum patient has been(More)
A-37-year old woman was referred to our hospital because of bilateral pulmonary micronodular shadows on chest X-ray. Prednisolone was reported to be administered for her coughs and dyspnea more than a month, but was discontinued recently. Under the diagnosis as miliary tuberculosis, we started to treat her with the combined use of pyrazinamide, isoniazid,(More)
A case of adult onset idiopathic pulmonary haemosiderosis (IPH) was reported. A 53-year-old man was admitted to our hospital because of repeated bloody sputum on June 2, 2006. Chest radiograph on admission disclosed diffuse infiltrative shadows in both lung fields, and one month later these shadows became more marked. The chest CT on July 5, 2006 showed(More)
