Acrosyringium, duct and secretory epithelium as well as myoepithelial cells of human eccrine sweat glands have been characterized by different immunostaining patterns with mono- and polyclonal antibodies to a wide spectrum of tissue antigens. Using monoclonal antibodies to neuron-specific enolase (NSE) and melanoma-associated antigens (LS 59, HMB-45, NKI/C-3) the expression of neuroectodermal a...

The forebody and foregut of Crepidostomum metoecus Braun, 1900 are invested with a tegument bearing regularly arranged surface tubercles comparable with the aspidogastrean surface structures. The tegument of the ventrolateral lobes and of the prepharynx is penetrated by ducts of eccrine gland cells. The frontal and prepharyngeal gland cells, localised in the parenchyma, discharge electron-dense...

In humans, evaporative heat loss from eccrine sweat glands is critical for thermoregulation during exercise and/or exposure to hot environmental conditions, particularly when environmental temperature is greater than skin temperature. Since the time of the ancient Greeks, the significance of sweating has been recognized, whereas our understanding of the mechanisms and controllers of sweating ha...

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 ...

Eccrine porocarcinoma (EPC) is a rare type of skin cancer arising from the intraepidermal portion of eccrine sweat glands or acrosyringium, representing 0.005-0.01% of all cutaneous tumors. About 20% of EPC will recur and about 20% will metastasize to regional lymph nodes. There is a mortality rate of 67% in patients with lymph node metastases. Although rare, the occurrence of distant metastase...

A 12-year-old girl was referred to our department for evaluation of a 6-cm erythematous, brownish, indurated plaque that has been present on the sacral area since birth (Figure 1). The gluteal cleft was not deviated, and the lesion was not tender to palpation. The patient complained of profuse sweating that would drench her clothes. These symptoms were distressing and unrelated to emotional str...

MAPK: mitogen-activated protein kinase MEK: MAPK/ERK kinase INTRODUCTION Several skin lesions resulting from keratinocyte hyperproliferation have been observed in melanoma patients receiving BRAF inhibitor monotherapy. The most common of these lesions are verrucal keratosis, Grover disease, plantar hyperkeratosis, actinic keratosis, cutaneous squamous cell carcinoma, and keratosis pilaris. More...
