These bumps sound like cysts but the discoloration and small bumps on penis can be due to Fordyce spots. Blocked sebaceous glands, swollen hair follicles and excessive testosterone production will cause 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. Regarding Fordyce spots, they are small, painless, raised, pale or white spots or bumps 1 to 3 mm in diameter that may appear on the shaft of the penis.
