<unk>  Stage III. Inflamed lesion.<unk> . This lesion is about 4 inches across.<unk>  Stage III. Open lesions are extremely painful.<unk>  can take the form of growths on the skin that are extremely painful and debilitating.<unk>  <unk> , sometimes known as acne inversa or Verneuil's disease, is a long-term dermatological condition characterized by the occurrence of inflamed and swollen lumps. These are typically painful and break open, releasing fluid or pus. The areas most commonly affected are the underarms, under the breasts, and the groin. Scar tissue remains after healing.<unk>  may significantly limit many everyday activities, for instance, walking, hugging, moving, and sitting down. Sitting disability may occur in patients with lesions in sacral, gluteal, perineal, femoral, groin or genital regions; and prolonged periods of sitting down itself can also worsen the condition of the skin of these patients. The exact cause is usually unclear, but believed to involve a combination of genetic and environmental factors. About a third of people with the disease have an affected family member. Other risk factors include obesity and smoking. The condition is not caused by an infection, poor hygiene, or the use of deodorant. Instead, it is believed to be caused by hair follicles that are near apocrine sweat glands being blocked, which in turn causes inflammation in the sweat glands. Diagnosis is based on the symptoms. No cure is known. Warm baths may be tried in those with mild disease. Cutting open the lesions to allow them to drain does not result in significant benefit. While antibiotics are commonly used, evidence for their use is poor. Immunosuppressive medication may also be tried. In those with more severe disease, laser therapy or surgery to remove the affected skin may be viable. Rarely, a skin lesion may develop into skin cancer. If mild cases of<unk>  are included, then the estimate of its frequency is from 1-4% of the population. Women are three times more likely to be diagnosed with it than men.
