title: Benign ovarian cystic teratomas with homunculi.
abstract: Two benign ovarian cystic teratomas, each containing a partial human body-like structure (homunculus), are described. One was found in a 30-year-old woman, and the second occurred in a prepubertal 10-year-old girl. Each of the 2 homunculi resembled the lower half of a miniature human body with buttocks, a pair of legs with recognizable feet, and a phallus-like structure in the anterior midline. A relatively well-developed osteocartilagenous skeleton was identified in each of the specimens. The literature pertaining to these so-called fetiform teratomas is reviewed. Only 17 previous cases have been described or mentioned in the English-language literature.
