CYLD cutaneous syndrome is a genetic condition characterised by the expansion of various noncancerous (benign) pores and skin tumors. These tumors acquire from structures connected with the pores and skin (pores and skin appendages), these as hair follicles. Additional than one sort of pores and skin tumor normally develops, like benign growths identified as cylindromas, spiradenomas, and trichoepitheliomas. Cylindromas had been beforehand believed to derive from sweat glands, but they are now normally thought to start off in hair follicles and normally show up on the scalp. Spiradenomas are connected to cylindromas and it is widespread to uncover characteristics of equally of these benign growths in a solitary tumor. Trichoepitheliomas occur from hair follicles and generally acquire on the pores and skin around the nose and higher lip.

Though the pores and skin tumors connected with CYLD cutaneous syndrome are generally benign, often they could turn out to be cancerous (malignant). When turning into malignant, tumors normally develop promptly and turn out to be open sores (ulcers). Affected individuals are also at improved danger of establishing tumors in structures other than pores and skin for illustration benign or malignant tumors of the salivary glands take place in some people with the condition.            

People with CYLD cutaneous syndrome generally start off establishing tumors in late childhood or in their teens. For good reasons that are unclear, women with CYLD cutaneous syndrome have a tendency to acquire much more tumors than males with this condition. Tumors have a tendency to develop bigger and improve in number over time. Massive benign tumors could turn out to be ulcers and inclined to bacterial infections. The tumors are most normally uncovered on the head and neck, like the scalp. Tumors that take place in the eyes, ears, nose, or mouth can have an affect on the senses, like eyesight and listening to. Significantly less often, tumors acquire on the torso, armpits, or genitals. Genital tumors could induce agony and sexual dysfunction. Not often, cylindromas acquire in the airways
and can induce difficulties with respiratory (respiratory insufficiency).

The tumors in CYLD cutaneous syndrome can be disfiguring and could add to depression or other psychological difficulties. 

CYLD cutaneous syndrome features the disorders beforehand identified as Brooke-Spiegler syndrome, various familial trichoepithelioma, and familial cylindromatosis. These disorders had been at the time believed to be distinctive diseases but are now viewed as to be the exact condition.
