Hi, I'm a 17 year old male. A few weeks ago I noticed a small, pea-sized lump on my scrotal skin. The lump was skin-coloured and fairly hard. There were also a few much smaller, white lumps dotted around the scrotal skin. A few days ago I noticed that the pea-sized lump had a small white bit at the top. It started to itch slightly so I scratched it and noticed a bit of liquid come out. The lump has now shrunk but the other smaller lumps remain. However, now there appears to be a larger, redish lump between my scrotum and my right thigh. It's quite hard and feels slightly sore when I touch it. Other than the lumps I don't appear to be suffering from any other symptoms.
The lumps may be unrelated but I just wanted to hear your opinions on what it may be and whether it's harmful or not.
It can be due to a boil or a sebaceous cyst. A sebaceous cyst is a closed sac occurring just under the skin which contains a "pasty" or "cheesy" looking substance called keratin.They may occur anywhere on body but scalp, ears, back, face, and upper arm, are common sites for sebaceous cysts. Blocked sebaceous glands, swollen hair follicles and excessive testosterone production will cause such cysts.
Generally no treatment is required but they become painful then it means they are infected,Then surgical excision by traditional wide excision, minimal excision, and punch biopsy excision may be required.
