Diagnostic delay in a patient with reactional lepromatous leprosy treated as testicular tuberculosis.

Leprosy is a chronic neglected and stigmatizing disease. Due to involvement of the peripheral nerves, it can result in physical disabilities, deformities, and emotional damage if not diagnosed and treated promptly. This is the case of a young patient with testicular pain and swelling and no improvement after a specific therapeutic scheme for tuberculosis. Clinical and laboratory reevaluation revealed hypoesthetic skin patches associated with post-burn crusted ulcers on the left arm, thickening of ulnar nerves, atrophy of interosseous muscles of the hands, positive skin smear microscopy, and testicular histopathology with numerous bacilli forming globi. These findings indicated lepromatous leprosy with type II reaction.
