A Rare Presentation of 17α Hydroxylase/17,20 Lyase Deficiency in a Patient with non-Hodgkin's Lymphoma: A Case Report.

ABSTRACT

17α­hydroxylase/17,20­lyase deficiency (17OHD) is a rare form of congenital adrenal hyperplasia that causes decreased cortisol and sex steroid levels and leads to high production of adrenocorticotropic hormone (ACTH). Although affected patients have absolute cortisol deficiency, they do not show clinical signs of cortisol deficiency or hyperpigmentation. These patients most commonly present with delayed puberty and amenorrhea at late pubertal age. Impaired production of sex steroids leads to ambiguous or female external genitalia in affected 46, XY individuals. In this report, we describe a patient with 17OHD who presented with hyperpigmentation and hypergonodotropic hypogonadism while receiving chemotherapy.
