causes for scalp lesions
Kerion (inflammatory Tinea capitis) Another cause of sores or lesions on the scalp is inflammatory Tinea capitis. It is caused by Tinea capitis which is medical term for yeast of the skin on the scalp. Unlike folliculitis, kerion is influenced by fungal infection. It is identified by pustules with tender areas.
Lupus can cause the hair on your scalp to gradually thin out, although a few people lose clumps of hair. Loss of eyebrow, eyelash, beard and body hair also is possible. In most cases, your hair will grow back when your lupus is treated. But some people with lupus develop round (discoid) lesions on the scalp. Because these discoid lesions scar your hair follicles, they do cause permanent hair loss. Lupus can also cause the scalp hair along your hairline to become fragile and break off easily, leaving you with a ragged appearance known as lupus hair.
