Alopecia mucinosa. Report of a case with diffuse alopecia and normal-appearing scalp skin.
A 69-year-old man had reversible generalized thinning of the scalp hair and normal-appearing scalp skin that proved to be secondary to follicular mucinosis. This case illustrates that when mild degrees of follicular degeneration and inflammation occur in this disorder, physical findings other than alopecia may be absent. In rare instances, follicular mucinosis can occur as a chronic diffuse noncicatricial alopecia.
