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.
Generally, Perineum lump can be related to:
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.
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.
Hidradenitis Suppurativa
Hidradenitis suppurativa is a chronic skin condition characterized by painful nodules and abscesses in the skin's folds.

Male, 20s
My experience was great. I was worried, but the symptom checker helped me narrow down what it might be. I feel a little relieved compared to when I first started, and it gives me a starting point for what my symptoms could mean.

Male, 50s
The questions asked and possible causes seemed spot on, putting me at ease for a next-step solution.

Female, 40s
I was actually very impressed with the results it provided because, although I didn’t mention it during the questionnaire because I thought it was unrelated, it suggested I may have something I’ve actually been diagnosed with in the past.
