EPIDEMIOLOGY
The perforating diseases are found worldwide, without any clear racial predilection. The very rare childhood-onset form of RPC is commonly familial, and childhood-onset EPS is occasionally familial. Although the exact inheritance pattern for both is still uncertain, isolated inherited EPS may have an autosomal dominant pattern. EPS affects men more often than women, with a ratio of ~4โ:โ1, whereas the sex distribution is nearly equal in RPC and acquired perforating dermatosis. Perforating folliculitis is said to be more common in women. In patients receiving maintenance hemodialysis, acquired perforating dermatosis is observed in an estimated 4.5% to 11% of patients. Acquired perforating dermatosis is more commonly encountered than the inherited perforating disorders.
