Dear Editor, Recently, percutaneous imaging-guided core needle biopsy (CNB) ensuring a high degree of diagnostic accuracy and minimal invasiveness has been widely practiced as an alternative to surgical biopsy [1]. However, the procedure itself can, very rarely, contribute to disease recurrence [1, 2]. The WHO classifies mammary carcinomas with(More)
The expression of proliferative cell nuclear antigen (PCNA) in follicular tumours of the thyroid was examined by immunohistochemistry. Both usual nonoxyphilic cell follicular tumours (non-OCT) and oxyphilic cell tumours (OCT) were subdivided into benign, indeterminate, encapsulated carcinoma, and widely invasive carcinoma types. Among non-OCT the(More)
Neovascularization, proliferation of synovial cells, and mononuclear cell influx and activation are characteristic events observed in synovial joints in the pathohistology of rheumatoid arthritis (RA). The objective of this study was to examine synovial inflammation in rabbit knees induced by intra-articular administration of human(More)
We report a rare case of spontaneous rupture of the extensor tendons at the wrist which was shown histologically to be related to calcium pyrophosphate crystal deposition disease. The causes of tendon rupture were chronic synovitis with crystal deposition and a dorsal prominence of the ulnar head.
Two cases of mucinous cystadenoma of the appendix successfully treated by laparoscopy are reported. An 81-year-old woman with lower right back pain was diagnosed with mucinous cystadenoma of the appendix or appendiceal carcinoma and underwent elective laparoscopic surgery. The other case involved a 70-year-old man with hematochezia who was diagnosed with(More)
PE-35 monoclonal antibody, detecting a cell-surface antigen of various types of carcinoma and normal epithelium, reacts exclusively with the medullary epithelium in the thymus; therefore, the antigen has been considered as a marker of medullary differentiation in thymomas. Using the catalyzed signal amplification method, which made it possible to apply(More)

Endoscopy revealed the presence of foreign bodies in the stomach, which was filled with a large volume of food (Figure 1). These foreign bodies were considered to cause intermittent gastric outlet obstruction. We tried to retrieve one of them with a polypectomy snare, but found it difficult because it had become a hard mass. Thus, we forcefully pulled it(More)
We report a case of Jaccoud’s arthropathy with forefoot plantar callosity. The lesser toe metatarsal heads were resected and Swanson’s double-stemmed flexible-hinge implant arthroplasty of the first metatarsophalangeal joint was performed. An osteolytic defect had formed around the implant after 2 years. Surgical revision comprised implant removal and(More)
