Non-scarring hair loss is a common problem that affects both male and female patients. Since any disturbances in the hair follicle cycle may lead to hair shedding, or alopecia, it is not surprising that the possible role of vitamin D in alopecia was investigated in many studies.

Although syphilitic alopecia is non-scarring hair loss often associated with other mucocutaneous lesions of secondary syphilis, it might well be the only presenting symptom of syphilis. Secondary syphilis was diagnosed in ten homosexual ...

A 67-year-old man with a three-year history of non-scarring alopecia that progressed to alopecia totalis despite intralesional glucocorticoid injections is presented. He developed 20-nail dystrophy that was recalcitrant to antifungal and anti-inflammatory treatments. Biopsy of the nail matrix showed histopathologic features of lichen planus. Alopecia totalis and isolated lichen planus of the na...

Alopecia areata is thought to be a T-cell mediated and cytokine mediated autoimmune disease that results in non-scarring hair loss. Poliosis has been described as a localized depigmentation of hair caused by a deficiency of melanin in hair follicles. A 57-year-old man with a history of alopecia areata developed white hair regrowth in areas of previous hair loss. We retrospectively reviewed the ...
