Hello and welcome to HCM,
Multiple red colored bumps on the scrotum
over a period of 10 years suggests a benign process.
Blood filled bumps which bleed profusely are suggestive of hemangioma
Hemangioma is benign tumor
of blood vessels.
They are harmless and rarely turn malignant.
However, it can cause pressure on the normal structures (scrotum in your case) and produce pressure effects.
Since, the hemangiomas are multiple, it is not feasible to remove them all.
However, If any hemangioma is causing pressure symptoms on normal structures, that lesion can be removed.
thanks and take care
