An unusual form of pemphigus vegetans.

Numerous vegetating plaques developed in a 63-year-old man followed up for the management of pemphigus vulgaris of 5 years' duration. These lesions occurred over the trunk and right upper arm with no involvement in the intertriginous area, and were controlled with systemic steroid and ODT. Direct immunofluorescence test showed heavy deposition of fibrinogen in the papillary dermis. To our knowledge, the occurrence of pemphigus vegetans in the non-intertriginous area is rare.
