INTRODUCTION: Primary palmar hyperhidrosis (PPH) mainly affects the sympathetic ganglia. This study aims to analyze the histopathological changes in the sympathetic ganglia of patients with PPH.
MATERIAL AND METHOD: We studied 55 tissue samples from 35 patients with PPH who underwent T2-T3 gangliectomy for definitive treatment of their disease, analyzing the presence of inflammation, chromatolysis and lipofuscin accumulation. Findings were analyzed in relation to age, compensatory sweating and type of surgery: unilateral, synchronic bilateral or sequential bilateral.
RESULTS: We found inflammation in 5.5%, chromatolysis in 61.8% and lipofuscin accumulation in 41.8% of the samples. Chromatolysis and lipofuscin were found without inflammation in 32.1%. Chromatolysis and lipofuscin accumulation were each found in 60% of the samples from synchronic bilateral sympathectomies. However, those percentages decreased between the first and second sympathectomies in sequential procedures, such that chromatolysis was found in 71.4% of first-procedure samples and 42.8% of second-procedure samples; the rates for lipofuscin accumulation changed from 64.2% to 14.2%. Although findings were unrelated to age, they did correlate with compensatory sweating, which was found in 79.7% of patients undergoing synchronic bilateral sympathectomy, 78.5% of sequential bilateral sympathectomy patients and only 56.25% of unilateral sympathectomy patients.
CONCLUSIONS: Neuronal death and lipofuscin accumulation unrelated to inflammation are evident in sympathetic ganglia from patients with PPH. Such changes are atypical for a group of patients whose mean age is 29 years, unless such lesions are the result of functional hyperstimulation. Surgery performed sequentially does not lead to overloading of contralateral T2-T3 ganglia; on the contrary, decreased injury is evident.
