A 21-year-old white woman presented with virilization, hirsutism, and acne of 1.5 years' duration. Endocrine testing demonstrated complete suppression of serum testosterone, from 5.3 to 0.6 ng/mL, and serum androstenedione, from 4.7 to 1.7 ng/mL, after oral administration of 50 micrograms of mestranol and 1 mg of norethindrone for 21 days. No suppression of either steroid was produced by dexamethasone, whereas serum dehydroepiandrosterone sulfate was suppressed from 5.2 to 1.9 micrograms/mL. A left salpingo-oophorectomy was performed for a 3 x 4-cm Sertoli-Leydig cell tumor of intermediate differentiation. Intraoperative studies demonstrated that the tumor secreted testosterone, androstenedione, 17 alpha-hydroxyprogesterone, and estradiol, but not dehydroepiandrosterone sulfate. These findings support the thesis that hormonal manipulation tests cannot differentiate between adrenal and ovarian virilizing tumors. Nor does the oral contraceptive suppression of testosterone secretion exclude an ovarian malignancy. The patient remains free of recurrence after 7 years.

We report a patient with primary amenorrhea accompanied by adrenal adenoma. A 21-year-old woman was admitted to our hospital because of primary amenorrhea and hyperprogesteronemia without virilization. Venous sampling showed progesterone overproduction at the left adrenal gland. Computed tomography revealed a 7 cm mass in left adrenal gland. Serum pregnenorone, 17-hydroxypregnenorone, dehydroepiandrosterone, 17-hydroxyprogesterone, deoxycorticosterone, and 11-deoxycortisol were elevated. The diagnosis of steroid hormone producing tumor was made. Following tumor resection, serum progesterone normalized 4 days later, and menarche occurred 51 days after operation. The present case indicated that adrenal functioning tumor should not be overlooked in patients with primary amenorrhea.

Androgen replacement therapy for male hypogonadism may be prescribed utilizing intramuscular, oral or more recently, topical formulations. With topical formulations, there is a risk of person-to-person transmission if appropriate precautions are not taken. We describe two cases of virilization in pre-pubertal children following passive transfer of paternal topical testosterone. A 21 month old male was referred with a 6 week history of pubic hair, phallic growth, and linear growth spurt. Genital examination revealed Tanner stage 2 pubic hair and Tanner stage 3 phallic development, which was discordant with the pre-pubertal testicular size (2 mL bilaterally). A 3 year 8 month old girl was referred for a 2 month history of increasing pubic hair development. Examination revealed Tanner stage 2 pubic hair and Tanner stage 1 breast development. Both of these patients had fathers who had been diagnosed with hypogonadism and were being treated with topical androgen gel therapy, which they applied to their arms and chest before bed. In addition, both patients often slept with their parents resulting in skin-to-skin contact. Investigations were consistent with gonadotropin independent virilization with both patients demonstrating elevated testosterone levels. Testosterone levels returned to normal pre-pubertal levels with no further development of secondary sexual characteristics following discontinuation of exposure to topical testosterone. Precautions must be taken to prevent person-to-person transfer of topical steroids. With the increasing popularity of topical steroids for the treatment of low testosterone, it is imperative that these therapies be prescribed and utilized judiciously to prevent harm, specifically gonadotropin-independent virilization.
