Stromal tumor of the sex cord in a woman with testicular feminization syndrome: imaging features

Complete androgen insensitivity syndrome with a Sertoli-Leydig cell tumor

BACKGROUND

The complete androgen insensitivity (testicular feminization) syndrome was described in phenotypic females with 46XY karyotype, presenting with primary amenorrhea, adequate breast development, and absent or sparse pubic or axillary hair. Gonads consist usually of seminiferous tubules without spermatogenesis.

CASE

We report the case of a 15-year-old girl with testicular feminization since age 4. She was admitted to surgically remove the testes from the inguinal canal. Microscopic examination of the left testis revealed a Sertoli-Leydig cell tumor and the draft of fallopian tube with adjacent seminiferous tubules.

SUMMARY AND CONCLUSION

These patients have a 5%-10% risk of developing germ cell tumors. Sertoli-Leydig cell tumors are uncommon neoplasms, usually benign in testicular feminization syndrome.

Intra-abdominal testicular seminoma in a woman with testicular feminization syndrome

We report a case of intra-abdominal testicular tumor in a 36-year-old married lady presenting with chief complaints of primary amenorrhea. The patient was later diagnosed with testicular feminization syndrome, a form of male pseudohermaphroditism. This testicular tumor was histologically proven as seminoma. Due to rarity, imaging findings in patients with testicular feminization syndrome and intraabdominal testicular tumor have been poorly documented. So far, only one case report had described the combined role of CT and MR imaging in intraabdominal testicular sex-cord stromal tumor. To our knowledge, this case is first to document USG and MR imaging in addition to MR spectroscopy features in intraabdominal testicular seminoma.

Complete androgen insensitivity syndrome with microtia: a rare presentation

Complete androgen insensitivity syndrome (CAIS) is a rare X-linked disorder characterized by a female body habitus and male genotype. The Müllerian duct derivatives are absent or rudimentary, and the testes are undescended. Microtia is characterized by a malformed auricle; and in some cases it is genetically transmitted with a non-sex-linked inheritance pattern. The presence of CAIS with microtia has not been documented previously, and this is the first case to describe the radiological findings of this rare presentation.

Molecular-cytogenetic characterisation of sex cord-stromal tumours: CGH analysis in sertoli cell tumours of the testis

Sertoli cell tumours (SCT) are rare and poorly explored neoplasias, and the genetic features of these uncommon tumours are largely unknown. Data about chromosomal aberrations in human SCT of the testis are very rare. We present in this paper the first molecular-cytogenetic study of SCT of the testis. DNA was isolated from paraffin-embedded tumour material from 11 patients with unilateral SCT. We used comparative genomic hybridisation to investigate changes in DNA copy number. The detected DNA imbalances showed variation from case to case, indicating a high genetic heterogeneity. Chromosomal aberrations were detected in 9 of the 11 tumours evaluated, with 13 losses versus 14 gains. The most frequent aberrations detected were gain of chromosome X (5 of 11 cases) followed by losses of entire or part of chromosomes 2 and 19 in three cases. This study suggests a high variability in histomorphological and genetic patterns. Only gain of the entire chromosome X seems to be a frequent aberration in these tumours. Further studies of these tumour types are necessary to clarify the significance of chromosomal alterations in carcinogenesis of SCT.
