Abstract

Swyer syndrome (46 XY pure gonadal disgenesis) is a rare endocrine disorder which presents with primary amenorrhea and poor development of secondary sexual characteristics, normal female external genitalia, normal Müllerian structures and streak gonads. In this case report, a 21-year-old patient was admitted with the complaint of primary amenorrhea. Poorly developed secondary sexual characteristics and normal female external genitalia were detected during physical examination. In hormonal evaluation increased FSH and LH levels , but decreased estradiol levels were detected. Pelvic ultrasonography revealed, decreased uterine and left ovarian size, and right ovary was not observed. Swyer syndrome was diagnosed according to karyotype analysis that was reported to be 46 XY. Bilateral gonadectomy and hormonal replacement treatment was recommended to the patient, however the patient refused the treatment. The patient applied for operation after 6 years, and underwent laparoscopic bilateral gonadectomy, incidentally diagnosis of disgerminoma was made. Adjuvant 3 cycles of chemotherapy including Bleomycin, Etoposide, Cisplatin was administered In genetic investigation of the patient who does not have a family history of cancer, BRCA2 gene mutation was detected and genetic counseling was given. The patient was disease-free 42 months after the operation. This report on Swyer syndrome described an older case who refused gonadectomy and progressed into disgerminoma. In addition to SRY gene mutation Swyer syndrome may be associated with BRCA 2 mutation.

Özet

Swyer sendromu (46 XY saf gonadal disgenezi), primer amenore ve az gelişmiş sekonder cinsiyet özellikleri ile ortaya çıkan; normal dişi dış genitaller, normal Müllerian yapılar ve çizgi gonadların görüldüğü nadir bir endokrin bozukluktur. Malignansi riski nedeni ile bilateral gonadların çıkarılması önerilmektedir. Bu çalışmada sunulan olgu 21 yaşında primer amenore ile başvurmuştur. Yapılan fizik muayenede sekonder cinsiyet özellikleri az gelişmiş, normal dişi dış genitaller saptanmıştır. Hormonal değerlendirmede FSH ve LH seviyeleri yüksek saptanırken, östradiol seviyeleri düşük saptanmıştır. Pelvik ultrasonografide uterus boyutları küçük, sol over boyutu azalmış saptanmış, sağ over gözlenememiştir. Karyotip analizi yapılan hastada 46 XY karyotipi saptanarak Swyer sendromu teşhisi konulmuştur. Hastaya gonadektomi ve devamında hormon replasman tedavisi önerilmiştir, ancak hasta tedaviyi kabul etmemiştir. Hasta 6 yıl sonra operasyon için başvurmuş, laparoskopik bilateral gonadektomi yapılmış, insidental olarak disgerminom tanısı konulmuştur. Hastaya postoperatif 3 kür kemoterapi (Bleomisin, Etoposid, Sisplatin) uygulanmıştır. Ailede kanser öyküsü bulunmayan hastaya yapılan genetik incelemede, BRCA2 gen mutasyonu saptanmış ve genetik danışmanlık verilmiştir. Hastanın cerrahi sonrası 42. ayda hastalıksız takibine devam edilmektedir. Bu raporda, Swyer sendromu saptanan ancak gonadektomiyi reddeden ve disgerminom saptanan ileri yaş bir olgu tanımlanmıştır. SRY gen mutasyonu ile birlikte BRCA 2 mutasyonu da Swyer sendromu ile ilişkili olabilir.
