Sindrom Klinefelter

Sindrom Klinefelter (SK) merupakan kelainan akibat adanya kromosom seks tambahan (47,XXY) yang menyebabkan hipergonadotropik hipogonadisme, dan infertilitas. Penampilan pasien SK hampir tidak berbeda dengan mereka yang berkariotip normal, tanpa gejala klinis yang khas selama masa anak, sehingga diagnosis ditegakkan setelah usia remaja atau dewasa muda. Keterlambatan dalam penegakkan diagnosis dapat menyebabkan hilangnya kesempatan tata laksana untuk memperbaiki hipogonadisme, gangguan kognitif, dan faktor-faktor psikososial. Dilaporkan kasus anak laki-laki 13 tahun dengan keluhan ginekomastia. Pada pemeriksaan fisis ditemukan bentuk tubuh eunokoid, volume testis yang kecil dan teraba keras. Pemeriksaan laboratorium menunjukkan peningkatan kadar LH dan FSH, dengan kadar testosteron yang masih dalam rentang normal. Diagnosis SK ditegakkan melalui pemeriksaan analisis kromosom dengan hasil 47, XXY.
