Eccrine Nevus in the Forearm of a 16-Year-Old Presenting as Unilateral Hyperhidrosis: A Clinicopathological Correlation Paradigm

“…Eccrine nevi are rare lesions included in the group of organoid nevi, with few reported cases in the literature. Clinical features of eccrine nevi are variable, including their age of presentation, number, location, size, signs, and symptoms [ 4 , 5 ].…”

Eccrine angiomatous naevus revisited

“…Dilatation of eccrine coils is a constant feature with amplification in their numbers, but associated enlargement of vascular channels may not be present. This modification has been termed “naevus sudoriferous.”[6] Apart from closely entwined pilar structures and infiltration of adipose tissue, profuse deposition of mucin in the connective tissue has been detailed in the literature.

Localized Unilateral Hyperhidrosis and Neurofibromatosis Type 1: Case Report of a New Association

“…Frey’s syndrome), associated with diabetes mellitus or parotid diseases [21, 22, 33]. Cutaneous diseases described in association with localized hyperhidrosis include palmoplantar keratodermas, glomus tumor, blue rubber bleb nevus, sudoriferous nevus, POEMS (polyneuropathy, organomegaly, endocrinopathy, M protein, skin changes) syndrome, speckled lentiginous nevus syndrome, Riley-Day syndrome, pachydermoperiostosis, Gopalan syndrome, causalgia, pretibial myxedema, Buerger disease and eccrine pilar angiomatous hamartoma, local injury and increased size of eccrine glands [5,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37]. LUH, without other cutaneous findings, may occur as a symptom of disease of the central nervous system or peripheral neuropathy, such as stroke, trauma, syringomyelia, tabes dorsalis or pressure on a nerve root caused by a benign or malignant condition such as cervical rib, vertebral osteoma, mesothelioma or pulmonary carcinoma [3, 4,6,7,8,9, 11, 33, 38].…”
