Firm nodule on the skin of the scrotum that is caused by an accumulation of sebum (a thick, greasy, cheese like substance) resulting from sebaceous gland blockage. Sebaceous cysts are very common and can occur in any area of hair-bearing skin, but mostly on the scalp. They are also found on the face, neck, back and scrotum.
They are multiple in number , Scrotal sebaceous cyst is whitish, yellowish or skin-coloured nodule and vary in size. They are usually the size of a pea. They occur singly or in groups. When multiple they fill up the entire scrotal skin and appear like a cauliflower or a bunch of grapes.
SYMPTOMS- cysts are usually painless. Cyst becomes painful if it gets infected and may burst to discharge pus.They may cause embarrassment and may be a cause of significant anxiety.
Cause is unclear but duct obstruction of a sebaceous gland in the hair follicle can result into accumulation of the sebum leading to development of cyst. They can develop at any age but are usually first noticed in adult life.
