Varma S K - - 1990
An 18-year-old girl had a cyst excised from the left buttock in 1988. The cyst was diagnosed to be a cutaneous ciliated cyst, since histologic examination using special stains demonstrated its lining to be similar to fallopian tube epithelium. Only 20 such cases have been published to date, and this ...
Whitney R W - - 1990
Two cases of diastematomyelia discovered in adults with minimal symptoms are described. In one case the presence of an associated thoracic neurenteric cyst supports the theory that a diastematomyelic spur represents a persistent neurenteric canal. The imaging findings are described and the incidence of diastematomyelia in adults is briefly discussed ...
Kaur K - - 1990
Although primary ovarian carcinomas are frequent, carcinomas having a primary origin in parovarian cysts are extremely rare.
