Ovotesticular disorder of sexual differentiation (OT-DSD) is a rare condition defined by the presence of both testicular and ovarian elements in the same individual. Definitive diagnosis is made based on histological assessment of the gonad/s confirming both ovarian and testicular components. In this paper, we describe how a diagnosis of 46XX, OT-DSD was made in a 20-year-old individual with enlarged breasts and ambiguous genitalia. The initial impression was congenital adrenal hyperplasia (CAH) based on 46, XX karyotype and absence of testes on physical examination and imaging. However, biochemical tests were inconsistent with CAH, hence a more probable diagnosis of 46, XX OT-DSD was considered. The patient suffered from gender dysphoria and after extensive counseling, he decided to undergo gender-affirming surgery: laparoscopic excision of the left gonad, subtotal hysterectomy, bilateral mastectomy, and a masculinizing genitoplasty. Histopathology of the left gonad revealed an ovotestes which confirmed the diagnosis of 46, XX OT-DSD.

PURPOSE: Patients with ovotesticular disorder of sex development (DSD) and mixed gonadal dysgenesis (MGD) usually present with asymmetric gonads and have wide phenotypic variations in internal and external genitalia. The differential diagnosis of these conditions is based on karyotype and pathological findings of the gonads. This study investigated the clinical features at presentation, karyotype, sex of rearing, and pubertal outcomes of patients with ovotesticular DSD and MGD.METHODS: The study comprised 23 patients with DSD who presented with asymmetric gonads. The presenting features, karyotype, sex of rearing, and pubertal outcomes were reviewed retrospectively.RESULTS: All 23 patients presented with ambiguous genitalia at a median age of 1 month (range, 1 day–1.6 years). Müllerian duct remnants were identified in 15 of 23 patients (65.2%). Fourteen patients were diagnosed with ovotesticular DSD, whereas the other 9 were diagnosed with MGD. Eight of 14 patients (57.1%) with ovotesticular DSD were raised as males, while 7 of 9 patients with MGD (77.8%) were assigned as males. One male-assigned patient with ovotesticular DSD changed to female sex at age 20 years.CONCLUSION: Patients with ovotesticular DSD and MGD manifest overlapping clinical presentations and hormonal profiles. It is difficult to determine the sex of rearing and predict long-term pubertal outcomes. Therefore, long-term follow-up is required to monitor spontaneous puberty, sex outcome, and urological and gynecological complications.

OBJECTIVETo investigate the characteristics, diagnosis, and treatment of ovotesticular disorder of sex development (OT-DSD).

METHODSWe retrospectively analyzed 2 cases of OT-DSD treated in our hospital. The patients were 19 and 15 years old, respectively, and both received systematic physical examination and examinations of the karyotype, sex hormone, adrenocorticotropic hormone (ACTH), color Doppler ultrasonography, urethrocystoscopy, and human chorionic gonadotropin (HCG) test. Under the laparoscope, we performed surgical gonad exploration, gonadectomy, and vulvar orthopedics. Intraoperative exploration and pathology confirmed true hermaphroditism in both cases, with sex selection as female. One underwent laparoscopic resection of the ovotestis, and the other removal of the testis with the ovarian tissue reserved.

RESULTSThe patients were followed up for 12 months postoperatively, which found no abnormality in either the vulvas or the genital glands.

CONCLUSIONSurgical exploration of the gonad is the only method for the diagnosis of OT-DSD and sex selection is the key to treatment. Laparoscopic surgical exploration of the gonad and vulvar orthopedics are the first treatment options.

Ovotesticular disorder of sex development (OT-DSD), previously known as true hermaphrodite, is a rare disorder of sexual differentiation in which the gonads of an individual are characterized by the presence of both mature ovarian and testicular tissues. The diagnosis has traditionally been applied only if an individual has 1) histologically verified ovarian follicles or proof of their prior existence (e.g. corpora albicantia) and 2) seminiferous tubules or spermatozoa. This paper introduces you to a 14 year-old, who presented with primary amenorrhea and enlarging abdominal mass, underwent exploratory laparotomy, salphingooophorectomy, histologically diagnosed as a possible case of a true hermaphrodite and chromosomally diagnosed as 45XO/46XY who developed endodermal sinus tumor, a germ cell tumor, considered highly malignant.

Recently, we reported the three wolves cloning with normal karyotype from somatic cells of endangered male gray wolves (Canis lupus), but one wolf had female external genitalia. In this study, we conducted further clinical, histological, and genetic analyses. This cloned wolf had a normal uterus but developed ovotestis. Through molecular analysis of the SRY gene, a mutation in the coding sequence of SRY gene could be excluded as a cause of intersexuality. This is the first report of a cloned wolf with a 78, XY ovotesticular disorder affecting sexual development characterized by bilateral ovotestes.

OBJECTIVETo study the clinicopathological characteristics and diagnosis of true hermaphroditism complicated with seminoma.

METHODSWe retrospectively analyzed the clinicopathological data of a case of true hermaphroditism complicated with seminoma and reviewed the related literature.

RESULTSThe patient was a 42-year-old male, admitted for bilateral lower back pain and discomfort. CT showed a huge mass in the lower middle abdomen. Gross pathological examination revealed a mass of uterine tissue, 7 cm x 2 cm x 6 cm in size, with bilateral oviducts and ovarian tissue. There was a cryptorchidism (4.0 cm x 2.5 cm x 1.5 cm) on the left and a huge tumor (22 cm x9 cm x6 cm) on the right of the uterine tissue. The tumor was completely encapsulated, with some testicular tissue. Microscopically, the tumor tissue was arranged in nests or sheets divided and surrounded by fibrous tissue. The tumor cells were large, with abundant and transparent cytoplasm, deeply stained nuclei, coarse granular chromatins, visible mitosis, and infiltration of a small number of lymphocytes in the stroma. The karyotype was 46, XX. Immunohistochemistry showed that PLAP and CD117 were positive, while the AFP, Vimentin, EMA, S100, CK-LMW, Desmin, CD34 and CD30 were negative, and Ki-67 was 20% positive. A small amount of residual normal testicular tissue was seen in the tumor tissue.

CONCLUSIONTrue hermaphroditism complicated with seminoma is rare. Histopathological analysis combined with immunohistochemical detection is of great value for its diagnosis and differential diagnosis.

Sex determination and differentiation require the balanced and sequential activation of transcription factors, signaling molecules, hormones and their receptors. Disorders of sex development (DSD) have heterogeneous groups of etiologies caused by mutations or deletions of genes involved in sex development. The DSD is categorized into 46, XX DSD, 46,XY DSD, sex chromosome DSD, ovotesticular DSD, and 46,XX testicular DSD. Precise diagnosis is essential for sex assignment, surgical correction of external genitalia, prevention of gonadal tumors, psychiatric support, and genetic counseling. The increased genetic knowledge in the field has opened up new diagnostic possibilities. The first line genetic testing for DSD is the assessment of the karyotype and the SRY gene. The follow-up genetic tests are performed for confirmatory diagnosis; the evaluation of copy number variants by array comparative genomic hybridization (CGH), direct sequencing of a specific gene, and functional analyses of mutations. A lot of genes can be analyzed by molecular laboratories and the number of available genes is growing. DNA analyses should be done under clinical assessment on the basis of family history, prenatal history, physical findings focused on external genitalia, endocrinologic data, and radiologic findings. Genetic counseling is essential to help patients and their families understand the disease status and the risk for recurrence in future pregnancies, and participate in the process of sex assignment. Children with DSD should be managed with a multidisciplinary team, including pediatric endocrinology, molecular genetics, cytogenetics, neonatology, urology, and psychiatry.

A differential diagnosis between the true hermaphroditism (TH) and mixed gonadal dysgenesis (MGD) has important clinical implications for gender assignment and the decision for early gonadectomy; however, variable clinical and histological features frequently lead to the confusion of TH with MGD. A 17- month-old boy was presented with proximal hypospadias with chordee and right non-palpable testis in his scrotum. He also had right auricular anomaly including a separated tragus with skin tag. Left testis was well palpable in his left scrotum. Diagnostic right inguinal exploration showed Mullerian structures such as a gonad like an ovary and a fallopian tube with a uterus, which were removed. Repair of hypospadias and right auricular anomaly was also done. Following ultrasonography (USG) showed a normal looking testis in left scrotum. His chromosome was 45, XO/46, XY. We report a difficult case of mixed gonadal dysgenesis mimicking true hermaphroditism which combines ipsilateral congenital auricular anomaly.
