Abstract:
Case reports of three patients with folliculitis of the posterior scalp are presented. In each an abnormality of hair growth was observed in the affected area in which bundles of hairs emerged from each follicle. The individual hair shafts came from independent papillae but converged into a single infundibulum in the upper dermis, and there was an associated granulomatous inflammation. This type of compound follicle with staphylococcal infection has rarely been reported in man before. Some of the mechanisms by which compound follicles can be formed are discussed.
