About the Symptom

The perineum is the space between the anus and scrotum in the male, or between the anus and the vulva in the female. Tumors in the perineum are rare and can feel like a painless lump which may be soft, firm or hard.

Possible causes

Generally, Perineum lump can be related to:

  • Condyloma Acuminatum

    Often referred to as genital warts, this sexually transmitted infection is caused by the human papillomavirus (HPV), and presents as small skin coloured bumps in the groin or perianal area. HPV is very common in women and men who have ever had sex - four out of five people will have HPV at some point in their lives, and most won't even know it.

  • Hidradenitis Suppurativa

    Hidradenitis suppurativa is a chronic skin condition characterized by painful nodules and abscesses in the skin's folds.

  • Infection after perineal laceration repair

    When delivering a baby vaginally, it is common to have a tear in the perineum (the area between the anus and vulva). Depending on the type of tear, they can require stitches to repair and take some time to heal. Due to the good blood supply in that area, most of these will heal well and have no complications. Sometimes however, the stitches and wound may become infected, causing the area to be red, swollen, and painful. The wound may also open up as a result.

  • Genital herpes
  • Behcet's disease
