We suggest that prophylactic thyroidectomy should not be delayed until adulthood in MEN 2A families carrying codon 804 RET mutations, but should be performed when there is CCH, before the development of MTC, as close as possible to age 6 years, which is the age of the youngest reported case of MTC in '804' families.
A pedigree of autosomal dominant expression of multiple benign adnexal tumours is presented. Seven cases spanning three generations are discussed. The clinical manifestations of these tumours are quite variable, including multiple papules concentrated on the face, scalp nodules and a large turban tumour. One member of the family had a linear papular eruption involving one half of his body. Histopathology of all lesions demonstrated benign adnexal characteristics, including well-characterized eccrine spiradenomas, trichoepitheliomas and an eccrine cylindroma. The cutaneous tumours occurring in these patients have continued to develop during their lifetimes. The authors propose that this pedigree has phenotypic characteristics consistent with Brooke-Spiegler syndrome.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
