The swordfish is reputedly the fastest swimmer on Earth. The concave head and iconic sword are unique characteristics, but how they contribute to its speed is still unknown. Recent computed tomography scans revealed a poorly mineralised area near the base of the rostrum. Here we report, using magnetic resonance imaging and electron microscopy scanning, the discovery of a complex organ consistin...

Cutaneous vulvar carcinomas are predominantly of squamous cell carcinoma type. Primary vulvar adenocarcinomas are rare with a poorly understood histogenesis. They are classified into extramammary Paget's disease, sweat gland carcinomas, and breast-like adenocarcinomas of the vulva. Adenocarcinomas, originating from Bartholin glands, can also present as vulvar adenocarcinoma. Rare adenocarcinoma...

Clear-cell hidradenocarcinomas are extremely uncommon sweat gland tumors with a predilection for the head and neck. In limited number of articles reporting breast involvement, primary focus concerns this entity's histological immunohistochemical characteristics. Since have potential to resemble carcinoma closely, diagnosis may be challenging. Therefore, authors report first case hidradenocarcin...

Sympathetic neurons are generated through a succession of differentiation steps that initially lead to noradrenergic neurons innervating different peripheral target tissues. Specific targets, like sweat glands in rodent footpads, induce a change from noradrenergic to cholinergic transmitter phenotype. Here, we show that cytokines acting through the gp 130 receptor are present in sweat glands. S...

Eccrine porocarcinoma is a rare, malignant neoplasm of eccrine sweat glands. It often occurs in elderly people, mean age of 67.5 years. The clinical features are variable and their localization is not related to sweat-gland concentration, occurring mainly on the feet and legs. Disease diagnosis and treatment should be as early as possible in order to avoid tumor aggressiveness that occurs in 20...

The sweat eccrine and apocrine glands of human skin secrete many functionally significant substances, including hydrolytic enzymes, onto its surface through the mechanisms secretion, excretion recruitment. Shown is their recreational origin as a secretory product digestive glands—pepsinogen by stomach glands, α-amylase—by pancreas. Hydrolases in epidermal barrier provide hydrolysis proteins, ca...

INTRODUCTION Chromhidrosis is a rare sweat gland disorder characterized by the excretion of colored sweat. It can be classified as apocrine, true eccrine, and pseudochromhidrosis. Amongst the different types of chromhidrosis, green chromhidrosis is extremely rare. We describe herein a case of blue green chromhidrosis induced by ingestion of homeopathic medicine. CASE REPORT A middle aged man ...

Sympathetic ganglia consist of noradrenergic and cholinergic neurons. The cholinergic marker protein vesicular acetylcholine transporter (VAChT) and the neuropeptide vasoactive intestinal peptide (VIP), co-expressed in mature cholinergic sympathetic neurons, are ®rst detectable during embryonic development of rat sympathetic ganglia. However, the subpopulation of cholinergic sympathetic neurons...
