Bilateral congenital cryptorchidism and unilateral Leydig cell tumor in an adult presenting with gynecomastia and primary infertility: A case report

Androgen Insensitivity Syndrome with Bilateral Gonadal Sertoli Cell Lesions, Sertoli-Leydig Cell Tumor, and Paratesticular Leiomyoma: A Case Report and First Systematic Literature Review

Androgen insensitivity syndrome (AIS) is a rare Mendelian disorder caused by mutations of the androgen receptor (AR) gene on the long arm of the X chromosome. As a result of the mutation, the receptor becomes resistant to androgens, and hence, karyotypically male patients (46,XY) carry a female phenotype. Their cryptorchid gonads are prone to the development of several types of tumors (germ cell, sex cord stromal, and others). Here, we report a 15-year-old female-looking patient with primary amenorrhea who underwent laparoscopic gonadectomy. Histologically, the patient's gonads showed Sertoli cell hamartomas (SCHs) and adenomas (SCAs) with areas of Sertoli-Leydig cell tumors (SLCTs) and a left-sided paratesticular leiomyoma. Rudimentary Fallopian tubes were also present. The patient's karyotype was 46,XY without any evidence of aberrations. Molecular genetic analysis of the left gonad revealed two likely germline mutations-a pathogenic frameshift deletion in the AR gene (c.77delT) and a likely pathogenic missense variant in the RAC1 gene (p.A94V). Strikingly, no somatic mutations, fusions, or copy number variations were found. We also performed the first systematic literature review (PRISMA guidelines; screened databases: PubMed, Scopus, Web of Science; ended on 7 December 2023) of the reported cases of patients with AIS showing benign or malignant Sertoli cell lesions/tumors in their gonads (n = 225; age: 4-84, mean 32 years), including Sertoli cell hyperplasia (1%), Sertoli cell nodules (6%), SCHs (31%), SCAs (36%), Sertoli cell tumors (SCTs) (16%), and SLCTs (4%). The few cases (n = 14, 6%; six SCAs, four SCTs, two SLCTs, and two SCHs) with available follow-up (2-49, mean 17 months) showed no evidence of disease (13/14, 93%) or died of other causes (1/14, 7%) despite the histological diagnosis. Smooth muscle lesions/proliferations were identified in 19 (8%) cases (including clearly reported rudimentary uterine remnants, 3 cases; leiomyomas, 4 cases). Rudimentary Fallopian tube(s) were described in nine (4%) cases. Conclusion: AIS may be associated with sex cord/stromal tumors and, rarely, mesenchymal tumors such as leiomyomas. True malignant sex cord tumors can arise in these patients. Larger series with longer follow-ups are needed to estimate the exact prognostic relevance of tumor histology in AIS.

Leydig Cell Testicular Tumor Presenting as Bilateral Breast Masses: A Case Report

Leydig cell tumors are rare but are the most common nongerm cell gonadal tumors. They are mostly benign but malignant variants have been reported. Leydig cells constitute the main androgen-synthesizing compartment in adult males but are also capable of estrogen production. This can manifest with clinical features of excessive hormone elaboration. We report a case of a 39-year-old man with abnormal bilateral breast development, reduced libido, and weak erection of 3 years' duration. He never noticed any testicular swelling before presentation. Examination revealed well-developed breasts bilaterally and a mass in the lower pole of the left testis. Scrotal ultrasound confirmed a hypoechoic tumor measuring 2 × 3 cm in the lower pole of the left testis and hormonal evaluation revealed a markedly elevated estradiol level. A diagnosis of estrogen-secreting testicular tumor was made. He had a testis-sparing excision of the scrotal lesion as well as liposuction and excision of glandular tissues of the breasts. He had an uneventful postoperative recovery and was discharged a day after surgery. Histology of excised testicular lesion revealed a benign Leydig cell tumor. Four months following surgery, there was an improvement in libido, erection, and sperm concentration of the patient. The patient was also very satisfied with the cosmetic outcome of the excision of the bilateral gynecomastia. We recommend self-examination of testicles as an important step for early diagnosis of testicular tumors.

A giant intra-abdominal right testicular seminoma in a bilateral undescended testicle: a case report

Cryptorchidism is the most common congenital malformation of the male genitourinary tract. An undescended testicle has a 10% chance of developing cancer, with an intra-abdominal testicle having the highest risk. We present a 24-year-old man with a history of bilateral cryptorchidism, complaining of lower abdominal mass for two months. An abdominal computed tomography scan showed an intra-abdominal mass lesion measuring 13 x 9 cm and displacing the bladder caudally. Exploratory laparotomy revealed a right intra-abdominal testicular tumor. A right orchiectomy and left orchidopexy was performed. Histopathological examination revealed a testicular seminoma. The patient was discharged without complications and was referred to the oncology department for chemotherapy and further management. Our findings support the early treatment and close monitoring of cases of cryptorchidism due to the risk of malignancy as well as the necessity of routine scrotal examinations in all males presenting with an abdominal mass.
