Bejel, or endemic syphilis, is a chronic skin and tissue disease caused by infection by a subspecies of the spirochete Treponema pallidum.

Bejel is also known by a variety of other names, including belesh, dichuchwa, endemic syphilis, nonvenereal syphilis, frenga, njovera, skerljevo, siti, or treponematosis-bejel type.[1][citation needed]

Causes[edit]

Although the organism that causes bejel, Treponema pallidum endemicum,[2] is morphologically and serologically indistinguishable from Treponema pallidum pallidum, which causes venereal syphilis, transmission of bejel is not venereal in nature,[3] generally resulting from mouth-to-mouth contact or sharing of domestic utensils, and the courses of the two diseases are somewhat different.

Presentation[edit]

Disfiguring infiltration of the nose, glabella, and forehead with clustered nodules in left interciliary region of boy with endemic syphilis.

Bejel usually begins in childhood as a small mucous patch, often on the interior of the mouth, followed by the appearance of raised, eroding lesions on the limbs and trunk. Periostitis (inflammation) of the leg bones is commonly seen, and gummas of the nose and soft palate develop in later stages.

Epidemiology[edit]

Bejel is mainly found in arid countries of the eastern Mediterranean region and in West Africa, where it is known as sahel. [sahel disease; to be distinguished from 'Sahel' the geographical band between North Sahara and Southern Sudan]

Treatment[edit]

It is treatable with penicillin or other antibiotics, resulting in a complete recovery.
