  3. Hidradenitis Suppurativa: Understanding Types...

Hidradenitis suppurativa is a special skin inflammation/infection originating from the so called apocrin sweat glands. It is related to hormonal balance and a genetically “thicker sweat” makes it more likely to happen. The presenting skin changes are similar to pimples (boils, infection/inflammation of the hair follicles) but somewhat deeper and not round but longer, worm or sausage like lumps result. The lumps then discharge pus and turns into rough scars, just to flare up again in the vicinity within a few months.

Most often affected areas of the body are the armpits, inguinal folds and the perianal, perineal, gluteal area. The infection, inflammation is in the deep tissues of the skin causing abscesses and scars and often require surgery.

What signs and symptoms one has with this problem?

Painful skin swellings/lumps in the perianal or genital (or armpit or under the breast) areas. The skin might look normal or red over the lumps. If left untreated the lump might bursts and discharges pus, then heals with a scar. On antibiotics the lesion settles, but it can flare up again until removed. Another lesion might shows up in the neighbourhood with similar symptoms.


Phases of disease: 1. boil under the skin 2. inflamed tract/sinus under the skin 3. inflamed tract(s) discharging pus.

Most affected areas: armpit; groin, perineum, under breasts
