Additional Information: Castellani's paint was perfected in 1905 by Aldo Castellani (1878-1971), an Italian physician and a specialist in tropical diseases. Castellani's paint is an excellent preparation for tinea cruris and moniliasis of intertriginous areas.1 It is effective in pustular dermatoses of the hands and feet,2 and has also been recommended for pruritus ani and pruritus vulvae.3 Colorless Castellani's paint may be used to reduce secondary bacterial contamination in onycholysis and in chronic paronychia.4
Castellani's paint dramatically improves inflamed skin around the the groin, particularly in patients with a history of long-term topical steroid application. Applying Castellani's paint is an effective way to dry oozing lesions, particularly in the groins and the toe webs.9
