Poromas are benign tumors of the distal portion of sweat gland ducts.. Poromas are rare, benign, cutaneous adnexal tumors. [1] Cutaneous adnexal tumors are a group of skin tumors consisting of tissues that have differentiated (i.e. matured from stem cells) towards one or more of the four primary adnexal structures found in normal skin: hair follicles, sebaceous sweat glands, apocrine sweat ...
If acne is occurring, it is because these gland ducts are blocked. Eccrine (merocrine) glands are most common. The secretions are very watery that contain some electrolytes; Apocrine glands produce a fatty secretion, thus giving away an odorous smell. These are located in the inguinal and axillary regions of the body, and include the mammary ...
Damaged sweat and sebaceous glands, hair follicles, muscle cells, and nerves are seldom repaired. They are usually replaced by the fibrous tissue. The result is the formation of an inflexible, fibrous scar tissue. Human skin cells are capable of repairing UV-induced DNA damages by the process of nucleotide excision repair. [2]
Frey's syndrome (also known as Baillarger's syndrome, Dupuy's syndrome, auriculotemporal syndrome, [1] or Frey-Baillarger syndrome) is a rare neurological disorder resulting from damage to or near the parotid glands responsible for making saliva, and from damage to the auriculotemporal nerve often from surgery.
Sweat glands, also known as sudoriferous or sudoriparous glands, from Latin sudor 'sweat', [6] [7] are small tubular structures of the skin that produce sweat. Sweat glands are a type of exocrine gland , which are glands that produce and secrete substances onto an epithelial surface by way of a duct .
Most people with hypohidrotic ectodermal dysplasia have a reduced ability to sweat (hypohidrosis) because they have fewer sweat glands than normal or their sweat glands do not function properly. Sweating is a major way that the body controls its temperature; as sweat evaporates from the skin, it cools the body.
Sudomotor function refers to the autonomic nervous system control of sweat gland activity in response to various environmental and individual factors. Sweat production is a vital thermoregulatory mechanism used by the body to prevent heat-related illness as the evaporation of sweat is the body’s most effective method of heat reduction and the only cooling method available when the air ...
Hidrocystoma (also known as cystadenoma, [1] a Moll's gland cyst, [1] and a sudoriferous cyst [1]) is an adenoma of the sweat glands. [2]: 787 Hidrocystomas are cysts of sweat ducts, usually on the eyelids. [3]: 664 They are not tumours (a similar-sounding lesion called hidroadenoma is a benign tumour).
