title: [A case of male dysgenetic pseudohermaphroditism detected by the rapid growth of phallus].
abstract: A case of male dysgenetic pseudohermaphroditism detected by the rapid growth of phallus is reported. A 10-year-old girl with rapid growth of a phallus during the past 6 months was referred to our clinic. Physical examination revealed a normally located urethral meatus and introitus with a 1.5 cm x 4 cm phallus. Radiographic studies revealed a vagina, uterus and fallopian tube-like structures. Karyotype was a mosaicism with 46, XY (71.5%), 45, X (26%), and others (2.5%). Bilateral gonads were dysgenetic testicular tissue with gonadoblastoma. Focal dysgerminoma was developed on the left side. Bilateral gonadectomy and feminizing phalloplasty were performed.
