What kind of tumor is generally found in the buttocks?

Tumors in the buttocks are generally benign, such as lipomas, fibromas, and epidermoid cysts (commonly known as "sebaceous cysts").

　　1. Lipoma

　　A lipoma is a common benign tumor that frequently occurs in areas with thicker skin. The treatment approach depends on the size of the lipoma and its impact on daily life. If the lipoma is small and solitary and does not interfere with daily activities, it may not require treatment. However, if the lipoma is large or causes pain or discomfort, surgical excision can be performed under the guidance of a physician in a dermatologic surgery or general surgery department.

　　2. Fibroma

　　Fibromas are classified into hard fibromas and soft fibromas. If the mass is hemispherical, relatively firm, and has a dry surface, it may be a hard fibroma containing abundant fibrous tissue. If the mass is round and shows ulceration or infection on the surface, it may be a soft fibroma. Fibromas are typically treated by surgical excision under medical supervision.

　　3. Epidermoid Cyst (Sebaceous Cyst)

　　Epidermoid cysts are benign tumors usually caused by blocked sebaceous gland secretions. If a lump on the buttock skin protrudes from the surface and feels smooth, elastic, and non-mobile upon touch, it may be an epidermoid cyst. Treatment options include surgical removal or laser therapy under a doctor’s guidance.

　　Additionally, tumors in the buttock area may also be skin tags. Small skin tags can be removed with laser treatment; after removal, the wound should be cleaned and treated with iodine and anti-scar ointment. For larger skin tags, surgical excision under medical guidance is recommended, followed by wound suturing.
