Steroid metabolites producing adenoma: a case report

Hyperandrogenism is the most prevalent cause of menstrual cycle abnormalities and infertility in women. Here, we present a case of a 32-year-old woman with a 7-year history of menstrual irregularity and infertility. Laboratory test results revealed elevated 17-hydroxyprogesterone, progesterone 21-deoxycortisol. Abdominal computed tomography found a 3,9х2,9х2,6 cm left adrenal tumor. Non-classic congenital adrenal hyperplasia was diagnosed initially, however, treatment with supraphysiological doses of dexamethasone proved ineffective and progesterone and 17-hydroxyprogesterone levels remained high. Genetic testing revealed no 21-hydroxylase deficiency. Laparoscopic adrenalectomy was performed with subsequent pathological report being compatible with an adrenal cortical adenoma. 17-hydroxyprogesterone, progesterone 21-deoxycortisol levels returned to the normal range postoperatively and the patient’s menstrual cycle normalized without additional medication. Steroid metabolites producing adenomas are also extremely rare with only a few cases found in patients without previous CAH diagnosis. When a patient with clinically and biochemically diagnosed NCCAH demonstrate no typical features and shows poor response to steroid therapy, the patient should receive multisteroid LC–MS/MS assay for glucocorticoids and androgens, adrenal and ovarian imaging and undergo CYP21A2 gene mutation analysis.
