Van Wyk and Grumbach syndrome is a medical condition defined by a combination of hypothyroidism, precocious puberty (usually with delayed bone age) and ovarian cysts in pre- and post-pubertal girls.

Presentation[]

Symptoms are ascites, pleural and pericardial effusions, elevated ovarian tumour markers, enlarged pituitary gland and elevated prolactin and alpha-fetoprotein levels.^{[citation needed]}

Mechanism[]

The presumed pathogenesis is that primary hypothyroidism causes enlargement and hyperstimulation of the pituitary gland which in turn cause ovarian hyperstimulation, ovarian cysts and precocious puberty.^{[citation needed]}

Diagnosis[]

Diagnosis is made by imaging/sonography and thyroid hormone tests.^{[citation needed]}

Treatment[]

The syndrome usually responds well to thyroid hormone replacement with complete resolution of symptoms.^{[citation needed]}

History[]

The syndrome was described in 1960 by Van Wyk and Melvin M. Grumbach.^[1]^[2]^[3]
