Name: Arrhenoblastoma and Thyroid Adenoma, Familial

Synonym: incl.: Arrhenoblastoma, Familial Clustering

Mode of Inheritance: AD

OMIM number: 107950  

Tumor features

ovarian Sertoli-Leydig cell tumor
thyroid adenoma
thyroid hyperplasia / goitre

Tumor features (possible)

hamartomatous polyps in small intestine
ovarian mucinous cystadenoma
Wilms' tumor (nephroblastoma)


A number of families with multiple cases of ovarian Sertoli-Leydig cell tumors (arrhenoblastomas) have been reported. In some of these families thyroid adenomas, often multiple were also present in some of the relatives with ovarian tumors as well as in relatives without these tumors[1;2]. A mucinous cystadenoma was reported twice in these families and one case of Wilms tumor was reported[1]. In the proband published by O'Brien et al.[2], a hamartous polyp was removed from the small intestine at the age of 3 months. Could this disorder be a variant of Cowden syndrome or Peutz-Jeghers syndrome?
