Brooke–Spiegler syndrome is a hereditary disorder characterized by predisposition to the development of skin appendage tumors and the major and minor salivary glands neoplasms. The role of the CYLD mutation in visceral neoplasms is still unclear, except for parathyroid tumor. We report the case of a 46 year-old patient with multiple cylindromas and trichoepiteliomas, a Brenner tumor of the ovary, and a negative family history for Brooke-Spiegler phenotype. Genetic analysis revealed R936X germline mutation in the proband but not in her relatives. The same somatic mutation was found in the Brenner tumor, together with a novel missense CYLD mutation (D889N), which has never been reported in the literature to our knowledge. A founder effect for R936X has been hypothesized due to its high; surprisingly in our case this mutation seems to be recognized as a de novo mutation. Future studies involving a greater number of cases are necessary to understand possible genotype/phenotype correlations, through the clinical analysis of the familial tumor spectrum.

Abstract

Brooke–Spiegler syndrome is a hereditary disorder characterized by predisposition to the development of skin appendage tumors and the major and minor salivary glands neoplasms. The role of the CYLD mutation in visceral neoplasms is still unclear, except for parathyroid tumor. We report the case of a 46 year-old patient with multiple cylindromas and trichoepiteliomas, a Brenner tumor of the ovary, and a negative family history for Brooke-Spiegler phenotype. Genetic analysis revealed R936X germline mutation in the proband but not in her relatives. The same somatic mutation was found in the Brenner tumor, together with a novel missense CYLD mutation (D889N), which has never been reported in the literature to our knowledge. A founder effect for R936X has been hypothesized due to its high; surprisingly in our case this mutation seems to be recognized as a de novo mutation. Future studies involving a greater number of cases are necessary to understand possible genotype/phenotype correlations, through the clinical analysis of the familial tumor spectrum.
