### Common Skin Conditions Causing Lumps and Bumps and Their Treatments 1. **Cysts**: Noncancerous pockets of tissue filled with fluid, pus, or other material. They can develop due to infections, clogged sebaceous glands, or foreign bodies. Treatment options include draining, cortisone shots, or surgical removal. 2. **Cherry Angiomas**: Smooth, cherry-red bumps made of blood vessels. They usually appear on the trunk of the body and are common in people over 40. Treatment is not necessary unless for cosmetic reasons or if they bleed, with options including laser removal or electrocautery. 3. **Dermatofibromas**: Harmless, round skin growths often found on the arms and legs. They contain scar tissue and feel like hard lumps. They can be surgically removed or flattened with liquid nitrogen if necessary. 4. **Epidermoid Cysts**: Benign cysts formed by an outpouching from a hair follicle, commonly found on the genitals, chest, and back. Treatment involves complete removal of the cyst sac to prevent recurrence. 5. **Folliculitis**: Inflammation of hair follicles caused by infection, chemical irritation, or physical irritation. More common in people with diabetes, obesity, or compromised immune systems. Treatment includes topical or oral antibiotics and antifungal drugs. 6. **Keratoacanthomas**: Rapidly growing, dome-shaped bumps with a central crusted plug, often appearing on sun-damaged skin in people over 60. They are considered low-grade skin cancer and can be removed surgically. 7. **Keratosis Pilaris**: Appears as small, rough bumps on the upper arms, thighs, cheeks, back, and buttocks. Treatment includes intensive moisturizing and possibly other topical treatments. 8. **Lipomas**: Soft tissue tumors under the skin that are usually harmless. They can be removed if they cause pain or for cosmetic reasons, using excision, liposuction, or lipotherapy. 9. **Neurofibromas**: Soft, fleshy growths that can turn malignant in rare cases. Treatment is not necessary unless they affect major nerves, in which case surgical removal is an option. Consult a doctor if you notice any lumps or bumps on your skin to determine the best course of action.
