Skin Lumps: Common Causes

• lipomas, fatty lumps under the skin
• enlarged lymph glands, usually in the armpits, neck, and groin
• cyst, a closed sac in or under the skin that is lined with skin tissue and contains fluid or semisolid material
• boils, painful, red bumps usually involving a hair follicle
• corn or callus, caused by skin thickening in response to continued pressure (for example, from shoes) usually occurring on a toe or foot
• warts, a skin virus that develops a rough, hard bump, usually appearing on a hand or foot and often with tiny black dots in the bump
• moles, skin-colored, tan, or brown bumps on the skin
• abscess, infected fluid trapped in a closed space from which it cannot escape
• cancer of the skin (any colored or pigmented spot that bleeds easily, changes size or shape, or crusts and doesn't heal)
