Three patients with Crohn's disease who developed the clinical features of hidradenitis suppurativa (HS) are reported. To our knowledge this association has not been previously described. These cases illustrate the similarity between cutaneous Crohn's and ano-genital HS once chronic and established.

Summary The dermatological findings on examination of 13 patients with Aquired Immune Deficiency Syndrome (AIDS) and a further 40 who arc anti‐HTLV III positive without AIDS, are presented. Six of the AIDS patients had Kaposi's sarcoma. Five AIDS patients and eight non‐AIDS patients had seborrhoeic dermatitis. Two AIDS and eight non‐AIDS patients have extensive folliculitis. Biopsy proven immune complex vasculitis developed in two AIDS patients shortly before death. One AIDS patient had acquired ichthyosis and another two developed asteatotic eczema and the fourth‘dry skin’. Fungal infection of the skin, angular cheilitis and a recent history of herpes zoster has also been commonly found. The authors believe that these various manifestations can be explained by low T cell immunity and the effects of severe chronic illness.

Streptococcus milleri was isolated from the active lesions of three patients with perineal hidradenitis suppurativa. In each patient, elimination of this organism by appropriate antibiotic therapy was accompanied by marked clinical improvement.
