GTR Home > Conditions/Phenotypes > Cylindromatosis, familial


The disorders classically referred to as familial cylindromatosis, Brooke-Spiegler syndrome, and multiple familial trichoepithelioma were originally described as distinct clinical entities. Patients with BRSS develop multiple skin appendage tumors including cylindromas, trichoepitheliomas, and spiradenomas. Patients with familial cylindromatosis have only cylindromas, and those with MFT1 have only trichoepitheliomas. However, because these disorders show overlapping phenotypic features, and because different manifestations of each have been described within a single family, many consider these disorders to represent a phenotypic spectrum of a single disease entity (Guggenheim and Schnyder, 1961; Welch et al., 1968; Gerretsen et al., 1995; Lee et al., 2005; Bowen et al., 2005; Young et al., 2006; Saggar et al., 2008). Van Balkom and Hennekam (1994), who preferred the designation 'dermal eccrine cylindromatosis' for familial cylindromatosis, provided a review. 'Eccrine' referred to histologic evidence that the tumors may originate from the eccrine sweat glands. Blake and Toro (2009) provided a detailed review of the spectrum of disorders associated with CYLD mutations. [from OMIM]
