Hidradenitis suppurativa, also known as HS and less commonly as acne inversa, is a chronic, noncontagious, inflammatory condition characterized by painful bumps or boils and tunnels in and under the skin.
It can be caused by many things, including skin-care products, picking, hormones, stress, medical issues, smoking, diet, and more. Some areas of your body are prone to certain types of acne, as well. Other types of breakouts may look similar to acne but have different causes and require different treatments.
Excess production of hormones, specifically androgens, GH, IGF-1, insulin, CRH, and glucocorticoids, is associated with increased rates of acne development. Acne may be a feature in many endocrine disorders, including polycystic ovary disease, Cushing syndrome, CAH, androgen-secreting tumors, and acromegaly.
A common skin condition, folliculitis happens when a hair follicle becomes infected or inflamed. This condition may look like acne, often starting out as small red bumps. You can have folliculitis on your face, arms, back and legs. Mild cases can be cared for at home, while other cases are treated by a dermatologist.
As the wound begins to dry, a crust starts to form in the outer layer. If the crust is yellowish and if there is a formation of pimples on or near the wound, it could be septic. Sores that look like blisters. If there is a formation of sores which look like pockets of fluid around the area, they could be septic.
Pemphigus vulgaris is an autoimmune blistering disease that commonly involves the scalp. Lesions of pemphigus vulgaris that persist on the scalp for a long period may be accompanied by tufted hair folliculitis.
Hidradenitis suppurativa usually starts around puberty, but it can occur at any age after puberty. This may suggest that sex hormones play a part. Many people with the condition also have acne and excessive hair growth (hirsutism).
High-dose vitamins B6 and B12 have also been linked to rosacea fulminans, a condition that looks like acne. Rosacea is marked by large red bumps and pustules that typically appear on the nose, chin, and/or cheeks.
Liver-related acne is often characterized by: Persistent breakouts, particularly on the face, back, and chest. Inflammatory acne with red, swollen pimples.
Medications (such as steroids) and other medical conditions (such as polycystic ovarian syndrome) can also cause acne. If your acne is stubborn, severe, or widespread, it is a good idea to see your doctor to discuss whether something else could be going on, and to review your current treatment.
Chronic Cutaneous Lupus
“Discoid” refers to the round shape of the sores or lesions that develop. These are thick, raised, scaly patches that are often pink and may flake or form a crust on the surface of the skin. Lesions most often appear on the face, ears, scalp, neck, and hands.
Molluscum contagiosum is a skin condition that is common in children but can occur at any age. It is caused by a virus that gives you pimple-like spots with a dimple in the middle. It can be spread by skin-to-skin contact, or when you bathe or share a towel with someone who has the infection.
Hidradenitis suppurativa (hi-drad-uh-NIE-tis sup-yoo-ruh-TIE-vuh), also known as acne inversa, is a condition that causes small, painful lumps to form under the skin. The lumps usually develop in areas where your skin rubs together, such as the armpits, groin, buttocks and breasts.
A Vitamin B deficiency can wreak havoc on your skin, causing acne, rashes, dry and flaky skin, cracked lips, and wrinkles. It can also make your skin more sensitive to sunlight, personal care products, and other potential aggressors, and can accordingly lead to redness and irritation.
The deficiency of vitamin B12 can cause specific skin manifestations, such as hyperpigmentation, vitiligo, angular stomatitis, and hair and nail changes [1].
Contrary to common assumptions, Vitamin B12 deficiency doesn't directly lead to weight gain. However, it can indirectly influence weight through its impact on energy metabolism. Insufficient B12 can lead to fatigue and weakness, which may reduce physical activity levels and, in turn, lead to weight gain.
The odor associated with HS can vary from person to person. The extent of infection or severity of a flareup can also affect it. Often the odor is unpleasant. People may feel embarrassed by the odor.
Leukemia cutis (LC) is manifested as clinically demonstrated skin infiltration via neoplastic leukocytes or their precursors into the epidermis, dermis, or subcutaneous tissue [1,2,3,4]. It is a relatively rare symptom observed usually in more advanced stages of the disease.
Severe vitamin A and C deficiency may cause folliculitis. [1] In vitamin A deficiency the skin shows follicular hyperkeratosis, dryness and generalised wrinkling. [11] It requires about 2 months of vitamin C deprivation to produce mucocutaneous signs, including perifollicular petechiae and follicular hyperkeratosis.
People with hidradenitis suppurativa may first develop small pimple-like bumps, sores, or boils on the skin. Unlike regular pimples, these sores are usually recurrent. They can affect both sides of the body and tend to develop in areas where the skin folds or experiences friction.
Trimethylaminuria (TMAU) is a rare disorder in which the body is not able to metabolize the chemical trimethylamine, and this causes body odor.
