Abstract:
A 65-year-old man presented with an approximately 5-year history of cutaneous nodules of the arms and legs. In addition, physical examination revealed bilateral thickening of ulnar and tibial nerves, distal weakness with hallux extension and finger abduction, and distal hypoesthesia of the left hallux. Histopathological analysis of the skin biopsy specimen showed a dense inflammatory infiltrate in the hypodermis, characterized by vacuolated macrophages containing multiple organisms. The Fite stain was positive confirming the diagnosis of multibacillary leprosy.
