ABSTRACT
Light microscopy of the hair forms an important bedside clinical tool for the diagnosis of various disorders affecting the hair. Hair abnormalities can be seen in the primary diseases affecting the hair or as a secondary involvement of hair in diseases affecting the scalp. Hair abnormalities also form a part of various genodermatoses and syndromes. In this review, we have briefly highlighted the light microscopic appearance of various infectious and non-infectious conditions affecting the hair.
ABSTRACT
An infant with diffuse nonscarring alopecia of scalp and radiologic features of scurvy responded dramatically to oral vitamin C therapy. The characteristic cutaneous manifestations of scurvy are usually not seen in infancy. The manifestations of initial stage of scurvy that are not related to collagen synthesis, as in the present case, should alert to the possibility of this potentially fatal condition.
