Blastomycosis-like pyoderma in association with recurrent vesicular hand eczema: good response to acitretin.

Blastomycosis-like pyoderma, also known as pyoderma vegetans, is an uncommon disease characterized by vegetating skin lesions mimicking blastomycosis or warty tuberculosis, often associated with staphylococcal and streptococcal infections. It is more commonly observed in elderly patients with impaired immunological capacity, and is often unresponsive to various therapeutic modalities. We describe a case of BLP that occurred on the palmar aspect of the left hand in an elderly female, affected with recurrent vesicular hand eczema. The disease resolved completely following the administration of oral acitretin 25 mg/day for 10 weeks.
