Abstract

Teratomas are neoplasms derived from two or more germ cell lines that may be either mature or immature. Teratomas occur in individuals aged 19–68 years old but some occur in younger individuals. The presenting symptoms are those of an intrapulmonary mass. Rarely, trichoptysis (literally, the expectoration of hair) has been described in some cases. Teratomas are slow-growing tumors, and slow growth of radiologically documented cases by CT will be suggestive of the diagnosis, particularly in cases showing associated fat, cavitation, and calcification. Lucencies within densities are said to be pathognomonic but not characteristic.
