The eccrine glands produce and secrete sweat, a change in the rate of secretion is manifested through one hypohidrosis or hyperhidrosis. The GRN provides a persistent localized hyperhidrosis associated with poor peripheral circulation, causing skin lesions including papules, vesicles and diffuse erythema. GRN have been attributed to various causes of infectious tuberculosis, superficial circulatory disorders, endocrine, autonomic balance disorders and hereditary.
