Background. Four epidemiologic types of Kaposi sarcoma (KS) are known: classic KS, endemic African KS, epidemic or acquired immunodeficiency syndrome–related KS, and KS associated with immunosuppressive therapy. In most of the latter patients, KS was reported to have developed after organ transplantation, particularly renal transplantation. Thirty‐nine patients who have not had a transplant have been reported to have KS associated with corticosteroid therapy. Methods. The authors studied 10 patients with the appearance of KS during corticosteroid therapy (6 men, 4 women; age range, 42–79 years) who were treated with corticosteroids for autoimmune disorders (5 patients), lymphoproliferative disorders (2 patients), and diseases unrelated to the immune system (3 patients). Results. Genetically programmed susceptibility to corticosteroid‐related KS was suggested by the descent of the study patients as well as most of those reported previously. The prognosis was guarded in all the study patients. Conclusions. Corticosteroids should be withdrawn to achieve clinical remission.

Eleven patients with pemphigus vulgaris and with eye complaints had histopathological and direct immunofluorescence (DIF) studies on biopsies of their conjunctivae. In eight of the patients the ocular symptoms preceded the other manifestations of pemphigus. None of the 11 patients had any detectable conjunctival blisters or erosions. The conjunctivitis in three of the patients proved on histopathology and DIF to be a manifestation of pemphigus vulgaris. In the remaining patients, conjunctival hyperaemia with or without a mucoid discharge was observed, but there were no specific histopathological features, although one of them had a positive DIF.

In a series of 100 adults with tinea faciei various dermatologic manifestations were mimicked, viz.: discoid lupus erythematosus in 52 patients, lymphocytic infiltration in 15, seborrheic dermatitis in 11, rosacea in 8, contacts dermatitis in 7, polymorphous light eruption in 4 and granuloma faciale in 3. Trichophyton rubrum was isolated in 78% of the respective cases, other isolated organisms being Microsporum canis (13 cases), Trichophyton violaceum in 6, Trichophyton mentagrophytes (asteroides) in 2 and Epidermophyton floccosum in 1 case. In 85% of these patients the nails were also involved by the same agent found in the lesions of the face. On the basis of these observations it is recommended that all adult patients with tinea faciei should undergo a comprehensive mycological investigation to find the primary focus, which may be an infected nail.
