It consists of sustained muscle contractions, frequently causing twisting, repetitive movements and abnormal posture. We report a case of schizophrenia with tardive dystonia and unusual features on brain MRI. The patient (a 37-year-old single male) had been suffering from schizophrenia during the past 20 years. At age 28, he developed spasmodic movements of the upper limbs, torticollis and opisthotonus, and was diagnosed as having tardive dystonia. Dantrolene sodium therapy successfully alleviated his dystonia. At age 37, he discontinued neuroleptics by himself. As a result, he had a relapse and entered our psychiatric ward. His psychiatric symptoms were auditory hallucination, religious delusions, and psychomotor excitement. Also his lasting mild tardive dystonia had deteriorated. Brain MRI revealed multiple lacunar infarction, ischemic changes and brain atrophy. In this case, these MRI findings might be related to the development of tardive dystonia. Switching to low-potency neuroleptics alleviated the tardive dystonia. Various factors relate to tardive dystonia, and diagnostic imaging such as MRI might be necessary for schizophrenia with tardive dystonia. 2001-10-30T15:00:00Z http://hdl.handle.net/10564/679 タイトル: RENOVASCULAR HYPERTENSION AND ERECTILE DYSFUNCTION SECONDARY TO POLYARTERITIS NODOSA : A CASE REPORT 著者: Yamano, Shigeru; Kyoda, Yusuke; Shiiki, Hideo; Fujimoto, Takashi; Hashimoto, Toshio; Kitauchi, Takanori; Kagebayashi, Yoriaki; Hirao, Yoshihiko 抄録: We describe a patient with secondary hypertension and erectile dysfunction due to polyarteritis nodosa. A 30-year-old man was admitted because of hypertension and impotence. Blood pressure was 156/94 mm Hg, and was similar in both arms. Superficial sensation was diminished in the soles of the feet. Plasma renin activity was elevated. Intra-arterial digital subtraction angiography (DSA) of the renal arteries showed bilateral multiple microaneurysms in peripheral arterial branches between the interlobular and arcuate arteries of both kidneys. DSA of the internal iliac artery, the internal pudendal artery, and the hepatic artery also showed multiple microaneurysms, as well as focal stenoses. A diagnosis of organic (vascular) erectile dysfunction was made based on findings by the Rigi-scan (Dacomed Inc.). The patient, then, had polyarteritis nodosa presenting hypertension and erectile dysfunction. 2001-10-30T15:00:00Z http://hdl.handle.net/10564/678 タイトル: A CASE OF MALIGNANT RENAL NEOPLASM WITH RHABDOID FEATURES IN AN ADULT 著者: Kumamoto, Hiromi; Ozono, Seiichiro; Tsujimoto, Sigehiro; Yoshii, Masato; Kitauchi, Takanori; Hosokawa, Yukinari; Mibu, Hisakazu; Kagebayashi, Yoriaki; Hirao, Yoshihiko; Ichijima, Kunio 抄録: We report a case of malignant neoplasm with rhabdoid features of the kidney in a 68 year old man. To our knowledge malignant rhabdoid tumor of the kidney (MRTK) has been limited to the pediatric age group. Malignant renal neoplasm similar to MRTK occurring in adults is very rare. However, there has been a recent review in which the authors found 23/480 cases of renal cell carcinoma (RCC) (4.7%) exhibiting rhabdoid features, all in adults. In the present case, examination of many sections of tumor-affected tissue revealed no sign of any other malignant tumor included RCC, so-called pure adult malignant rhabdoid tumor in the kidney. MRTK does not respond well to aggressive chemotherapy regimens and survival tends to be short. This patient remains alive with no metastasis and local recurrence more than 45 months from the operation without adjuvant therapy. 2001-10-30T15:00:00Z http://hdl.handle.net/10564/677 タイトル: CYTOLOGIC CHARACTERISTICS OF A MALIGNANT PROLIFERATING TRICHILEMMAL CYST 著者: Ishida, Eiwa; Nakamura, Mitsutoshi; Konishi, Noboru; Matsunaga, Shigeo; Morishima, Hidekazu; Honda, Junko; Sekigawa, Susumu 抄録: The proliferating trichilemmal cyst (PTC)is a tumor that originates from hair follicles. It is almost always benign, but rare lesions have been reported with malignant potential. In the present case, the patient had a mass on the right side of her neck for a few years, which suddenly increased in size. Cytologic examination revealed many atypical squamous cells staining well with orange G and light green, suggestive of a squamous cell carcinoma. Total extirpation was performed under general anesthesia, gross pathology revealing a focally cystic tumor approximately 5 cm in diameter. The final diagnosis was malignant PTC from the characteristic features. We here report cytologic findings for this case with regional lymph node metastasis. 2001-10-30T15:00:00Z
