Objective: To describe the case of the most hyperandrogenaemic ovarian mucinous cystadenoma reported to date. Methods: We present the clinical, laboratory and radiologic ﬁndings in a patient with an unusual diagnosis according to age and the clinical behaviour of the tumour, as well as a review of relevant literature. Results: A 77-year-old women came to our consult because of fronto-parietal alopecia and an augmentation of the abdominal perimeter since 1 year ago. Clitoromegaly was observed during the physical examination. Hormonal analysis showed elevated testosterone and dehydroepiandrostenerone-sulphate levels (659 ng/dL and 1950 ng/ml, respectively), and imaging examination described an andexal cystic mass dependent on the right ovary. Pathological diagnosis was “mucinous cystoadenoma”. After surgery, clinical and analytical alterations were normalized. Conclusion: Although ovarian mucinous cystadenomas are classically classiﬁed as “nonfunctional” tumours, they exceptionally can act as functional, and produce testosterone levels as high as directly secreting hormones or germ cell tumours. examination, the following ﬁndings were recorded: blood pres- CASE REPORT sure: 125/80 mmHg, pulse: 88 bpm, height: 1.74 m, weight: A 77-year-old woman was evaluated in our outpatient endo- 53 kg, body mass index: 24.5 kg/m and waist circumference: crinology clinic because of alopecia.

It had a whitish-grey coloration and a cystic membran- ous appearance within a yellowish serous content. Its micro- scopic examination showed nests of luteinized cells in the cyst wall (Fig. 2) with a ﬁnal diagnosis of ’mucinous cystadenoma with stromal luteinization’. Three months after surgery, the patient had a normal serum total testosterone of 36 ng/dl. DISCUSSION The present clinical case exempliﬁes how many times postme- nopausal hyperandrogenism becomes in a diagnostic challenge. Postmenopausal virilization may be associated to adrenal or ovarian androgen-secreting tumours or to benign conditions. A detailed clinical history is critical to make out between the mild phenotype that characterizes benign causes from the rapid pro- gression and severe hyperandrogenism, including virilization, of androgen-secreting tumours. When symptoms clearly develop after menopause, hyperandrogenism is severe, progression is rapid and virilization or defeminization is present, adrenal and ovarian imaging must be immediately ruled out. Postmenopausal virilization may result from adrenal tumours, including androgen-secreting carcinomas and adenomas; from ovarian Figure 1: Abdomino-pelvic magnetic nuclear resonance. Voluminous mass, tumours, including Sertoli–Leydig cell tumours (androblastoma, with a cystic appearance, dependent on pelvic structures arrhenoblastoma), granulosa-theca cell tumours and hilus cell tumours; or from benign ovarian conditions such as ovarian stro- mal hyperplasia and hyperthecosis . Rare causes, such as trans- fer of testosterone from a male partner using testosterone gels, have been also described. Ovarian mucinous cystadenomas are classically considered as ‘non-functional’ tumours. This neoplasm represents around 8–25% of all ovarian tumours. It is more prevalent from the third to ﬁfth decades of life, being exceptional before puberty and after menopause. Very few cases of postmenopausal women with an androgen-producing mucinous cystadenoma had been reported, most of them in pregnant women [2–5]. Anecdotically, this tumour is diagnosed in adolescents , and to the best of our knowledge, only two cases have been reported in postmenopausal women [7, 8]. Only three of them had severe hyperandrogenemia [3, 7, 8]. In our patient, circulat- ing total testosterone levels were on male range, a feature asso- ciated to other androgen-secreting neoplasms and germ cell tumours . The reason why those epithelial tumours can secrete andro- Figure 2: Histopathologic examination, ovarian cells with a positive inhibin gens as a functional one is not well known.
