Fourniers gangrene
Fournier gangrene is a type of necrotizing fasciitis or gangrene affecting the external genitalia or perineum. It commonly occurs in older men, but it can also occur in women and children. It is more likely to occur in diabetics, alcoholics, or those who are immunocompromised.
About one per 62,500 males are affected per year. Males are affected about 40 times more often than females. It was first described by Baurienne in 1764 and is named after a French venereologist, Jean Alfred Fournier, following five cases he presented in clinical lectures in 1883
Initial symptoms of Fournier gangrene include swelling or sudden pain in the scrotum, fever, pallor, and generalized weakness. It is characterized by pain that extends beyond the border of the demarcated erythema. Most cases present mildly, but can progress in hours. Subcutaneous air is often one of the specific clinical signs, but is not seen in >50% of presenting clinical cases. More marked cases are characterized by a foul odor and necrotic infected tissue. Crepitus has been reported. It begins as a subcutaneous infection. However, necrotic patches soon appear in the overlying skin, which later develop into necrosis
