Regional lymph node enlargement may be present.
Deep bacterial infection that has an ulceration beneath the crusts. Ecthyma may be accompanied by fever and malaise.
Folliculitis is infection of hair follicle and surrounding area. Commonly involved sites are hair bearing region that is subject to friction and maceration. Clinically presents as redness, warm painful, Pustules- that may rupture and leave behind a raw area
Abscess are walled–off collections of pus often larger than furuncles.
Treatment of bacterial infections: Oral and topical antibiotics, as per requirement (Based on culture and sensitivity of the organism demonstrated in the pus collection) Rarely, in recurrent cases long term therapy may be required. Proper hygienic measures are to be instituted.
