finding that describes the diagnosis of some primary cicatricial alopecias as noted mainly in the central scalp, and includes CCCA, folliculitis decalvans, and any other potential centrally presenting cicatricial alopecia. This term is not often used in the literature to signify diagnostic terminology.

The mechanism of pathology of CCCA remains unknown; thus, the cause has only been postulated and not proven. CCCA is suspected to have a multi-factored cause. However, one theory involves pressure exerted on the internal root sheath leading to damage, which leads to the recruitment of inflammatory

A similarly sounding term is central centrifugal scarring alopecia (CCSA). (L.C. Sperling, Central, centrifugal scarring alopecia. In: L.C. Sperling, Editor, An atlas of hair pathology with clinical correlations, Parthenon Publishing Group, New York (2003), pp. 91–100). This is a clinical

The terminology of CCCA has been a source of regular confusion. Recent clarifications have been made, with the term "central centrifugal cicatritial alopecia" adopted as a diagnostic category by the

Type VI or VII. Early symptoms may include pruritus, dysesthesias and tenderness. On examination the skin is thin with few follicular ostia and later in the disease the scalp may appear shiny.

Treatments for CCCA remain investigational. Altering hair care practices has not been proven to assist in hair rejuvenation. High-dose topical steroids, antibiotics, immunomodulators such as

CCCA usually begins at the central (sagittal) midline of the scalp. It is symmetric and exhibits scarring as the name suggests. It involves solely the top of the scalp or may progress to
