Mucinous cystic neoplasms (MCN) of the pancreas are mucin-producing cystic tumors with an ovarian-like stroma (OLS). In the present study MCN were obtained from 27 patients. These MCN were derived from 22 pancreas, three livers, spleen, and mesentery. MCN in various organs have common clinicopathological profiles, being unilocular or multilocular cystic(More)
It is well known that there are discrepancies in the diagnosis of gastrointestinal neoplasia between Western and Japanese pathologists. In the West, colorectal cancer (CRC) is defined by invasion through the muscularis mucosa into the submucosa, especially depending on the presence of desmoplasia. In Japan, however, CRC is defined based on a combination of(More)
Spontaneous regression of hepatocellular carcinoma (HCC) is rare. We found spontaneous regression of HCC in a 53-year-old Chinese with liver cirrhosis. A liver mass 3 cm in diameter was revealed by B-ultrasonography. The resected mass showed histologically complete necrosis. The necrotic tissue was filled with large debris from a neoplastic tissue,(More)
A 66-year-old male with unbearable pruritus and jaundice was admitted for detailed examination. Blood tests on admission showed increased bilirubin with a dominant direct fraction. Ultrasonography and computed tomography performed subsequent to admission showed no narrowing or distension of the bile ducts. As the jaundice symptoms were not improved by the(More)
We report a case of a 44-year-old woman with bilateral ovarian carcinoma that had metastasized from the colon and mimicked primary mucinous cystadenocarcinoma. Macroscopically, both ovarian tumors were large, multiloculated cystic masses with abundant mucinous content. Histologically, they were lined with mucinous epithelium with mild to moderate nuclear(More)
A 63-year-old woman was admitted to hospital with pain in the right lower quadrant. Abdominal computed tomography (CT) revealed a 60-mm cystic mass at a site corresponding to the appendix. The mass wall on the appendicular ostium was thickened and enhanced by contrast, while calcification was observed in the mass wall on the appendicular tip. No projection(More)
A 39-year-old male without contributory medical history had sustained progressive double vision, ptosis, and trigeminal pain for 2 weeks. Physical examination revealed total ophthalmoplegia and visual field defect with normal blood examination and chest radiography. Cranial computed tomography revealed a hyperdense mass in the left frontotemporal fossae(More)
We experienced a case with a synovial cyst accompanied by asymptomatic lumbar vertebral fracture that required differentiation from spinal metastasis. An 82-year-old man suffered from right leg and anal pain. Computed tomography (CT) showed L5 spondylolysis. Magnetic resonance images (MRI) revealed an intra spinal cyst and acute lumbar vertebral fracture of(More)
We have reviewed 38 patients with invasive candidiasis and examined its predisposing factors, usefulness and limitation of cultural study in its diagnosis, and effective usage of amphotericin B in its treatment. Invasive candidiasis was diagnosed in 2.4% of the patients admitted during the past 5 years. One of the most important predisposing factors for(More)
