An enigmatic trio of Klinefelter's syndrome, autoimmune hypothyroidism and nephrotic syndrome.

Klinefelter's syndrome is the most common chromosomal disorder associated with testicular dysfunction and male infertility. Those affected by Klinefelter's syndrome are at increased risk of systemic lupus erythematosus, breast cancer, non-Hodgkin's lymphoma, and lung cancer. Nephrotic syndrome in association with Klinefelter's syndrome has never been reported in the literature.
