RESUMO
El término disgenesia gonadal pura hace referencia a mujeres fenotípicas con infantilismo sexual, amenorrea primaria, hábito eunucoide y un cariotipo 46, XX o 46, XY sin anomalías cromosómicas. Puede asociarse a complicaciones como osteoporosis y síndrome metabólico, elevando el riesgo cardiovascular. Se presenta una paciente femenina de 16 años y 8 meses de edad que acude a consulta de endocrinología por presentar amenorrea primaria.
The term pure gonadal dysgenesis refers to phenotypic women with sexual infantilism, primary amenorrhea an d the eunucoid habit and a 46, XX or 46, XY karyotype without chromosomal abnormalities. It can be associated with complications such as osteoporosis and metabolic syndrome, increasing cardiovascular risk. We present a female patient of 16 years and 8 months of age who attended endocrinology clinic for presenting primary amenorrea.

A 23-yr-old phenotypic female was seen for primary amenorrhea. Her pubic hair was relatively well developed and external genitalia showed normal female appearance, but breast development was retarded. Transvaginal ultrasonographic examination showed a small uterus with indistinct streak gonads, but both ovaries were not detected. Cytogenetic study revealed 46,XY. In FISH and PCR, the sex-determining region of Y chromosome (SRY) was not detected. We report here a case of 46,XY pure gonadal dysgenesis with loss of the SRY.

Leopard syndrome, a feature of a syndrome, is a acronym of Lentiginosis, Electrocardiographic conduction abnormalities, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth, and Deafness. It is one of the autosomal dominant neurocutaneous traits accompanied by neurologic abnormality. We have experienced a case of Leopoard syndrome associated with 46,XX pure gonadal dysgenesis, which was diagnosed by laparoscopic biopsy, karyotyping, and dermatologic consultation. So we report this case with a brief review of literatures. In our knowledge, this very rare case is presented for the first time in Korea.

Dysgerminoma developed in a 21-year-old phenotypic female patient with 46,XY pure gonadal dysgenesis, Swyer syndrome. This patient presented with pelvic mass associated with abdominal pain and primay amenorrhea. Clinical characteristics showed a typical stigmata of gonadal dysgenesis: primary amenorrhea, sexual infantilism, a small uterus and left streak gonad. A 46,XY karyotype was made by lymphocyte culture. The patient was counseled to undergo operation, chemotherapy and hormon therapy. She underwent bilateral gonadectomy with total hysterectomy, partial omentectomy and multiple pelvic wall random biopsy. Histological examination revealed dysgenetic gonads with dysgerminoma. After surgery, the patient received chemotherapy and also was started on hormone replacement therapy. She is currently alive with no evidence of disease after 19 months from surgery.

Gonadoblastoma and dysgerminoma developed in a 24-year-old phenotypic female patient with 46,XY pure gonadal dysgenesis. This patient presented with primary amenorrhea. Clinical characteristics showed a typical stigmata of gonadal dysgenesis: primary amenorrhea, sexual infantilism, a small uterus and bilateral streak gonads. A 46,XY karyotype was made by lymphocyte culture. The patient was counseled to undergo a prophylactic bilateral gonadectomy, but she refused. Three years and three months after the initial diagnosis she felt a growing pelvic mass. Bilateral gonadectomy and total hysterectomy were performed. Histological examination revealed gonadoblastoma and dysgerminoma on both gonads. After surgery the patient received radiation therapy and also was started on hormone replacement therapy. Two years and two months after treatment by surgery the patient is well and free of recurrence.
