Cytological analysis of atypical squamous epithelial cells of undetermined significance using the world wide web.

Objective: The low-level consistency of the cytodiagnosis of uterine cervical atypical squamous epithelial cells of undetermined significance (ASC-US) employing the Bethesda System has been reported, suggesting the necessity of a wide survey. We presented cases judged as ASC-US on the Web and analyzed the voting results to investigate ASC-US cytologically.

Study Design: Cytology samples from 129 patients diagnosed with ASC-US were used.

Detection of human papillomavirus in a urothelial carcinoma mimicking urethral caruncle.

Primary carcinoma of the female urethra is an uncommon diagnosis, accounting for less than 0.02% of all carcinomas in women. Urothelial carcinomas occupying the distal urethra in young females are considered to be extremely rare.

Tumoral calcium pyrophosphate dihydrate crystal deposition disease of the temporomandibular joint: identification on crystallography.

This paper reports a case of calcium pyrophosphate dihydrate (CPPD) crystal deposition in the temporomandibular joint (TMJ) of a 59-year-old man with the chief complaint of severe pain in the left TMJ. On CT a radiopaque area was seen around the condylar process of the left TMJ with irregular destructive bony changes. A provisional diagnosis of crystalline-induced arthritis was made on histopathology of a biopsy specimen.
