1. Lipoma: Lipoma is a benign lump formed by abnormal proliferation of fat cells, which usually occurs under the skin of limbs and trunk. Generally there is no need to deal with it, but if there are pressure symptoms or other discomforts, it needs timely surgical excision treatment.
2. Dermatofibroma: Dermatofibroma is a benign tumor formed by the proliferation of fibroblasts, which can occur in the arms or legs. It can be treated by intradermal injection of trimethoprim and compound betamethasone injection, which can promote the softening and flattening of nodules, or by superficial tumor excision.
3. Sebaceous cyst: It is a cystic swelling formed locally when the secretions of sebaceous glands cannot be discharged normally from the mouth of hair follicles. The key to treatment lies in the complete surgical removal of the cyst.
