Anhidrosis associated with alcohol‐related peripheral neurop
The present case has been reported in the British Journal of Dermatology.

A 70‐year‐old man presented with anhidrosis 5 years after he had developed alcohol‐related peripheral neuropathy (ALN). Perspiration was reduced in his lower limbs compared with normal, assessed by a thermal sweating test using the iodine-starch reaction.

Quantification of nerve fibres by confocal microscopy revealed a decreased innervation of eccrine glands over a lower perspiration area than normal, and no decreased innervation in an age‐, sex‐ and area‐matched patient without neuropathy.

Key takeaway:-
Rigorous analysis by confocal microscopy may reveal a significant reduction of innervated eccrine glands in a patient with ALN
