A Case of Carcinoid Tumor and Low Grade Mucinous Adenocarcinoma Arising in Ovarian Mature Cystic Teratoma / 대한산부인과학회잡지

Mature cystic teratoma of the ovary is the most common ovarian germ cell tumor and benign, but malignant transformation occurs in less than 2% of benign mature teratoma. Of the malignancies arising in teratomas, squamous cell carcinoma is the most common, however, carcinoid tumors or adenocarcinomas arising in mature cystic teratoma are uncommon, especially simultaneously. We present an unusual case of premenopausal woman having carcinoid tumor and mucinous adenocarcinoma simultaneously arising in ovarian muture cystic teratoma.

Acoustic Rhinometry in Nasal Provocation Test

A nasal provocation test is the most reliable diagnostic test to confirm allergen in allergic rhinitis. However, there are neither specific objective methods nor a standardized method and interpretation. In 20 normal subjects and 86 allergic rhinitis patients, we applied acoustic rhinometry as a new objective method to assess changes in nasal patency induced by nasal allergen challenge, a procedure which is used for confirming allergic rhinitis. The result shows that a minimal cross-sectional area (MCA) and volume from the nose tip on back to 7 cm (nasal cavity volume) after allergen challenge were significantly decreased in allergic rhinitis patients in comparison with the control subjects. We conclude that acoustic rhinometry can provide a sensitive index for evaluating the results of a nasal provocation test.
