Abstract

Study: Case report.

Importance: Worldwide over three million people are living with disabilities due to leprosy. Brazil is the second country with the highest number of new cases registered. The magnitude and high risk of disability make the disease a public health problem. The diagnosis of leprosy can be simple. However, in the absence of skin lesions and with many possibilities of neurological impairment, diagnosis can become a challenge.

Comments: We report the case of a patient referred to the neurology service with a clinical history and electrophysiological tests compatible with demyelinating polyneuropathy, without any skin lesion at admission examination. The initial clinical research was directed to the diagnosis of acquired inflammatory demyelinating polyneuropathies such as Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) and its variants. However, after anamnesis and detailed physical examination, the absence of the ataxic component and the predominant presence of sensory alterations of fine fiber, nerve thickening and important epidemiological factor for leprosy, led to the suspicion and investigation of this disease by nerve biopsy that was suggestive of leprosy. After three months, in a new patient examination to biopsy areas of anesthesia to reinforce the diagnosis, there was the appearance of extensive slightly hypochromic lesions in the trunk and lower limbs, whose biopsy defined the diagnosis of leprosy.
