Because sweat secretion is facilitated by mechanical contraction of sweat gland structures, understanding their structure-function relationship could lead to more effective treatments for patients with sweat gland disorders such as heat stroke. Conventional histological studies have shown that sweat glands are three-dimensionally coiled tubular structures consisting of ducts and secretory portions, although their detailed structural anatomy remains unclear. To better understand the details of the three-dimensional (3D) coiled structures of sweat glands, a whole-mount staining method was employed to visualize 3D coiled gland structures with sweat gland markers for ductal luminal, ductal basal, secretory luminal, and myoepithelial cells...

Hu Xia, Kai Feng
Dermcidin (DCD) was found in isolated human skin sweat glands with antimicrobial effect, and was defined as a kind of new small molecule antimicrobial peptide. It was a part of human sweat glands in the skin as the immune system's innate defense. With the studies of DCD, its extensive biological functions are gradually discovered. Since 2010, a number of studies have shown that DCD may be a new risk factor for atherosclerosis. And the role of DCD in ischemic heart disease has drawn increasing attention in particular its relationship with insulin secretion and glycemic control, nitric oxide (NO) synthesis and hypertension, platelet aggregation and acute myocardial infarction (AMI)...

BACKGROUND: Diabetes-associated microvascular complications such as retinopathy and neuropathy often lead to end-organ and tissue damage. Impaired skin microcirculation often precedes the detection of other advanced diabetic complications. The ANS-1 system contains a redesigned sympathetic skin response (ANS-1 SSR) device that measures sudomotor function, a photoplethysmography sensor, and a blood pressure device to comprehensively assess cardiac autonomic neuropathy and endothelial dysfunction...

Human WNT10A mutations are associated with developmental tooth abnormalities and adolescent onset of a broad range of ectodermal defects. Here we show that β-catenin pathway activity and adult epithelial progenitor proliferation are reduced in the absence of WNT10A, and identify Wnt-active self-renewing stem cells in affected tissues including hair follicles, sebaceous glands, taste buds, nails and sweat ducts. Human and mouse WNT10A mutant palmoplantar and tongue epithelia also display specific differentiation defects that are mimicked by loss of the transcription factor KLF4...

A missense variant in the autophagy-related ATG4D-gene has been associated with a progressive degenerative neurological disease in Lagotto Romagnolo (LR) dogs. In addition to neural lesions, affected dogs show an extraneural histopathological phenotype characterized by severe cytoplasmic vacuolization, a finding not previously linked with disturbed autophagy in animals. Here we aimed at testing the hypothesis that autophagy is altered in the affected dogs, at reporting the histopathology of extraneural tissues and at excluding lysosomal storage diseases...

Chondroid syringoma is an unusual, benign skin appendageal tumor originating from the eccrine and apocrine sweat glands resembling mixed tumors of the salivary glands. It develops as a slow-enlarging, small, cutaneous nodule or mass. The lesions are usually seen in older men on head and neck. This is a clinical report of a 46-year-old lady who presented with a slowly growing nodular protruding mass in a cheek. The clinical and histologic findings of the tumor are demonstrated. The clinician and the pathologist should take into account the tumor among differential diagnosis not to overlook the lesion...

Exocrine secretion of NaCl follows the "pump-leak" mechanism of active salt movement across an epithelial barrier followed by the movement of osmotically obliged water. Glandular exocrine secretion of NaCl rich fluids is found in most exocrine glands of the gastro-intestinal tract, the tear and sweat glands and also in airway epithelium This article is protected by copyright.

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic skin condition that can affect any area with apocrine sweat glands and has the potential to involve multiple sites concurrently. Commonly affected sites include the axilla, groin, perineum and perianal areas. In this study we performed a literature review on the surgical methods for HS and describe an innovative technique for reconstructing axilla HS using an inner-arm transposition flap. METHODS: We reviewed all cases (5 cases from 4 patients) of transposition flap reconstruction performed by the senior author at a single London tertiary hospital from 2008-2013...

We report on an atypical clinical course of a patient with the very rare diagnosis of an apocrine sweat gland carcinoma with lymphatic metastasis, a single metachronous distant metastasis and a now reached survival time of more than 4 years and give a review about the current literature. Only a very small number of cases have been described. The recommendations for diagnostics and treatment of this tumor, therefore, are not based on prospective randomized studies but upon case reports and on new immunohistochemical and genetic markers...

BACKGROUND: Frontal fibrosing alopecia (FFA) is a primary lymphocytic scarring alopecia occurring mainly in postmenopausal women. A range of facial lesions have been described in FFA, such as lichen planus (LP) pigmentosus, red dots, facial papules, and perifollicular and diffuse erythema. These lesions can be the first sign of FFA. LP pigmentosus is a rare variant of LP. The first description of LP pigmentosus associated with FFA (in 2012) reported 22 cases of LP pigmentosus among 44 cases of FFA affecting South African patients...

INTRODUCTION: Primary apocrine sweat gland carcinoma (PASGC) is an extremely rare neoplasia whose management and treatment are still evolving. The only curative therapy is wide local excision. Many patients have metastasis at the time of the diagnosis, mainly because this neoplasm has been misdiagnosed as some benign skin lesions. PRESENTATION OF CASE: We herein report a case of a 72-year-old-man with PASGC affecting the axilla and regional lymph nodes that underwent surgical resection and lymphadenectomy at our Institution...

Ductal eccrine carcinoma (DEC) is a rare sweat gland carcinoma with ductular differentiation. Clinically, it is characterized by a slowly growing, hardened plaque or nodule predominantly located on the head and neck. Histologically, DEC shares similar features to invasive breast carcinoma, thus causing great diagnostic challenges. We report a 69-year-old woman who presented with a hardened plaque on the axilla. A skin biopsy was performed and metastatic invasive breast carcinoma could not be ruled out. Complete excision and further workup were subsequently conducted, leading to the diagnosis of estrogen receptor positive DEC with associated axillary lymph node metastases...

BACKGROUND: Primary focal axillary hyperhidrosis is a chronic distressing disorder affecting both the sexes. When the condition is refractory to conservative management, we should go for more promising therapies like intradermal botulinum toxin A (BtxA) injections in the axilla, and surgical therapies like subcutaneous curettage of sweat glands. AIMS AND OBJECTIVES: The aim of this study is to compare the efficacy, safety and duration of action of intradermal BtxA injections in one axilla and subcutaneous curettage of sweat glands in the other axilla of the same patient with axillary hyperhidrosis...

BACKGROUND: Hidradenocarcinoma is a rare malignant tumour involving the sweat glands. It classically arises de novo, only rarely resulting from pre-existing hidradenoma. The literature contains few reports of lymph node metastasis in this tumour. We report a case of a patient with hidradenocarcinoma of the heel associated with inguinal node metastases. PATIENTS AND METHODS: We report the case of a 64-year-old patient with a history of chronic smoking, who in the last two years developed a painless nodule in his right heel, with no prior injury, and which gradually increased in size to become an ulcerated tumour...

Quantitative assessment of small fiber peripheral neuropathy often involves an evaluation of the interaction between the C-fiber sudomotor nerve and local sweat rate (SR). Typically, some sort of quantitative sudomotor axon reflex test (QSART) is performed to aid in diagnosing small fiber dysfunction. The currently used QSART demonstrates only moderate test-retest reliability and therefore limits its usefulness in tracking small fiber dysfunction. A new experimental model to examine small C-fiber function in the skin using intradermal electrical stimulation and simultaneous monitoring of SR is proposed...
