Comedones are the skin-coloured, small bumps (papules) frequently found on the forehead and chin of those with acne. A single lesion is a comedo. Open comedones are blackheads; black because of surface pigment (melanin), rather than dirt. Closed comedones are whiteheads; the follicle is completely blocked.
Rupture of a cyst
- Combination oily and dry mid-facial skin
- The contents of the cyst may penetrate the capsular wall and irritate surrounding skin.
- The area of tender, firm inflammation spreads beyond the encapsulated cyst.
- Sterile pus may be discharged.
Secondary infection
- A ruptured cyst may infrequently become secondarily infected by Staphylococcus aureus, forming a furuncle (boil).
