Bromhidrosis is a condition in which an individual has excessive body odor. There are two variants depending on whether eccrine or apocrine glands are affected. Apocrine bromhidrosis occurs only after puberty and is typically due to bacteria breaking down fatty acids in sweat. The type of skin flora present influences the odor, and Corynebacterium is thought to produce a particularly pungent scent.

Eccrine bromhidrosis can be either localized or generalized. Localized eccrine bromhidrosis occurs most commonly on the feet as well as other areas that are particularly prone to maceration secondary to sweat as this leads to the bacterial breakdown of keratin and the production of odor.

Generalized eccrine bromhidrosis usually occurs due to ingestion of certain substances or systemic illness. Therapies for bromhidrosis are generally targeted at reducing sweat and bacteria from the affected area, though antibiotics and surgical sweat gland destruction can be considered. Chromhidrosis, or colored sweat, is due to the presence of lipofuscin pigment in sweat glands, most commonly apocrine sweat glands. This pigment can lead to the production of yellow, blue, green, or black sweat.

Treatments include botulinum toxin injection and capsaicin cream. Miliaria, or sweat rash, is a skin disease caused by the blockage or inflammation of eccrine sweat glands. There are three types of miliaria dependent on the level of obstruction: crystalline, rubra, and profunda. Treatment for miliaria includes maintaining a cool environment, cool compresses, and applying topical corticosteroids and calcineurin inhibitors. Fox-Fordyce is a skin disorder caused by the blockage of apocrine sweat glands that leads to the formation of pruritic, skin-colored papules, most commonly in the axilla and groin.

This condition can occur in any individual, but women between the ages of 13 and 35 are the most at risk. Topical therapies include corticosteroids, calcineurin inhibitors, clindamycin, and retinoids. Other forms of treatment include surgical excision and phototherapy. Handbook of clinical neurology.

This is because as the water in sweat evaporates, it takes body heat with it. The other kind of sweat glands are known as apocrine glands. The apocrine glands are found in places like the armpits, scrotum, anus, and labia majora. They are typically larger than eccrine glands and their ducts tend to open into hair follicles instead of hairless areas of skin. These glands, unlike the eccrine glands, serve virtually no role in the regulation of body temperature.

These are also the glands largely responsible for body smells, as their excretions are converted by skin bacteria into various chemicals we associated with body odor. Unlike eccrine glands, the exact function of apocrine glands is unknown and debated. We do know they are activated during times of stress, pain, and sexual foreplay but for what reasons is yet to be made clear. Sebaceous glands are found in most of the skin except the palms of the hands and the soles of the feet.

Sebaceous glands are the oil secreting glands of your body. This is why they are also called the oil glands. They are a type of holocrine simple saccular alveolar gland. Their function is to secrete a substance called sebum, a mixture of fatty substances, entire sebum-producing cells, and epithelial cell debris.

The sebaceous glands are located in the dermis, the middle layer of the skin, and they develop from the epithelial cells of the hair follicle itself the external root sheath of the hair follicle. Sebaceous gland ducts thus usually open up into the upper part of a hair follicle, called the infundibulum. The infundibulum is part of the pilosebaceous canal, the one responsible for discharging sebum and one that is composed of the infundibulum and the short duct of the sebaceous gland itself.

However, some sebaceous gland ducts open directly onto our skin surface such as at the corner of the mouth and the glans penis. Regardless, the secretion of sebum out of the gland is helped along by the contraction of the arrector pili muscle. While the sebaceous glands are present just about all over the skin, they are notably absent on the palms of the hands and the soles of the feet.

The sebum being excreted by your body today began production around 8 days ago. Sebaceous Gland: Schematic view of a hair follicle with sebaceous gland. Sebaceous glands are involved in numerous conditions. During puberty, various hormones cause them to produce a lot of sebum and this therefore contributes to oily skin. If a duct of a sebaceous gland is clogged with sebum, a whitehead results.

If this material is allowed to dry and oxidize, it will become darker, forming a blackhead. If a sebaceous gland becomes infected, moderate and severe forms of acne are the result. The glands lining the ear canal that produce earwax cerumen are called ceruminous glands. They are modified sebaceous glands. The fingernail is an important structure made of keratin.
