Angiokeratoma Circumscriptum of the Tongue.

Angiokeratoma circumscriptum is rare cutaneous disorder. It usually presents as multiple,red, blue or black asymptomatic papules on lower extremities. Oral involvement, common in systemic form, is rare in localized forms. We report a case of angiokeratoma circumscriptum of tongue, involving both dorsal and ventral aspects.

Comparative efficacy of narrow-band ultraviolet B phototherapy alone and its combination with topical 8-methoxypsoralen in psoriasis.

Background: Very few studies using the combination of topical 8-methoxypsoralen (8-MOP) and narrow-band ultraviolet B (NBUVB) have been performed, especially in Indian patients. A combination of oral psoralen with NBUVB has been shown to have a superior efficacy as compared with NBUVB alone in psoriasis. Aims: Comparison of the efficacy of topical psoralen NBUVB (combination) versus NBUVB alone in psoriasis. Methods: Thirty patients with plaque psoriasis were taken up for the study and NBUVB phototherapy was given twice weekly. The target lesions on one side were treated with 0.1% topical 8-MOP 15 min before the irradiation. The treatment period was 12 weeks or 24 exposures. Results: The number of treatment sessions and cumulative NBUVB doses were lower in the combination therapy as compared with NBUVB monotherapy, although the differences were not statistically significant. Conclusion: To conclude, topical 8-MOP enhances the therapeutic effects of NBUVB therapy without increasing the incidence of adverse effects.
