The successful treatment of lupus pernio with the flashlamp pulsed dye laser.

Lupus pernio of the nose is the most characteristic cutaneous lesion of sarcoidosis. It is cosmetically disfiguring and can be the cause of significant morbidity. In particular, the affected skin is often red or purple due to increased vasculature. It is particularly resistant to both surgical and medical therapy. We describe a patient with lupus pernio affecting her nose, which showed a dramatic improvement following treatment with the pulse dye laser (PDL). A biopsy taken after treatment showed the continued presence of sarcoidal granulomas. We therefore feel that treatment with the PDL is an effective tool in improving the cosmetic appearance of lupus pernio, but does not influence the underlying disease process.

Topically applied niacinamide in isoniazid-induced pellagra.

A patient with tuberculous meningitis developed a pellagra-like skin eruption after treatment with isoniazid. Administration of the drug was continued, and a topical preparation of niacinamide (nico-tinamide) was applied to one half of the face and the back of one hand. The areas treated responded rapidly, and subsequently all affected areas of the patient were treated, with almost complete resolution of the rash. At the same time, there was noticeable improvement in the patient's depression and apathy. We suggest that all of these changes could be due to percutaneous absorption of niacinamide.

Cutaneous and ocular reactions to practolol.

A total of 21 patients suffering from drug-induced rashes from practolol have been seen over the past two years. The clinical manifestations varied, with the morphological appearances of the rash resembling those of eczema, lupus erythematosus, lichen planus, and a highly characteristic toxic erythematous psoriasiform eruption. Persistent ocular damage was a feature in three cases.
