Borderline Tuberculoid Leprosy Masquerading as Granuloma Annulare: A Clinical and Histological Pitfall

Abstract

This is the first reported case of leprosy masquerading both clinically and histologically as GA. Dermatopathologists should be aware of the possibility of leprosy given the presence of perineural lymphocytes amidst any pattern of granulomatous infiltrate and obtain a Fite stain.
