Surgery for ulnar nerve decompression and drainage of a caseous granuloma in a neural form of leprosy in children.

Key Clinical Message: The findings in the literature, as well as those described in this study, emphasize the need for systematic and longitudinal care for patients with neglected diseases during and after treatment, mainly in low-middle income countries. Abstract: Leprosy is a chronic, granulomatous, mycobacterial infection caused by mycobacterium leprae, affecting the skin and peripheral nervous system. We present a case of a 13-year-old child with leprosy for more than a year, indicating decompression of the ulnar nerve. During surgery, an intraneural large caseous granule was evidenced.
