Ochronosislike pigmentation from hydroquinone bleaching creams in American blacks.
Two patients had pitch-black pigmentation and colloid milium formation following the use of 2% hydroquinone-containing bleaching creams. These are among the first known cases in American blacks, although this phenomenon has been recognized previously in African blacks. Ultrastructural studies indicated that the pigment was due to the formation of elastotic fibers. These fibers attained an enormous size and disintegrated, leaving irregular fibers and fragments dispersed in the dermis. It is important that this clinical picture be recognized, since the use of these bleaching creams is widespread.

Patch stage Kaposi's sarcoma.
The patch stage of Kaposi's sarcoma (KS) has been recently recognized as histologically distinct from that seen in well-developed violaceous nodules of KS. We report a patient with patch stage KS and its angioendothelioma-like histology. The presence of glomerulus-like vascular structures is a newly described feature.

Kaposi's sarcoma after immunosuppressive therapy with prednisone.
Immunosuppressed patients are at risk of acquiring Kaposi's sarcoma. We describe here a 66-year old man with bronchial asthma who was receiving immunosuppressive medication (prednisone given for systemic effect) and in whom Kaposi's sarcoma developed. The literature on this subject is reviewed.
