The perineum is the surface region inferior to the pelvic diaphragm between the pubic symphysis and the coccyx. Many perineal masses extend from the pelvis. However, masses can arise from the perineum with or without pelvic extension. Typically, patients with a lesion in the perineum present with either perineal, gluteal, or labial swelling or

An infected perianal cyst typically presents with perianal soreness, swelling, and tenderness. The pain gets worse when pressure is put on it. On examination, an infected cyst is seen with inflammation around the infected area. This cyst can be seen with the naked eye and can rupture spontaneously resulting in temporary relief of symptoms. Fistula formation may occur in the perianal region. Genital Crohn disease can also result in perianal fistulae but lacks the other features of hidradenitis suppurativa. Infections of the perianal skin Erythrasma. Erythrasma is an infection caused by Corynebacterium minutissimum.

The anatomical anal canal extends from the perineal skin to the linea dentata. Surgically, the anal canal extends from the perineal skin to the anorectal ring. This is the circular upper border of the puborectal muscle which is digitally palpable upon rectal examination. The anorectal ring lies approximately 1-1,5 cm above the linea dentata. Fistula formation may occur in the perianal region. Genital Crohn disease can also result in perianal fistulae but lacks the other features of hidradenitis suppurativa. Infections of the perianal skin Erythrasma. Erythrasma is an infection caused by Corynebacterium minutissimum.
