Long meatballs on the buttocks without pain or itching may be caused by dermatofibroma, sebaceous cysts, lipoma and other reasons.
1. Dermatofibroma: it is caused by focal proliferation of fibroblasts or histiocytes, associated with localized minor skin injuries, clinically manifested as round or ovoid pimples, usually with no self-awareness of symptoms, which may lead to buttocks long meatballs without pain or itching.
2. Sebaceous cysts: sebaceous gland ducts are obstructed, and the increased content within them swells, forming retention cysts in the sebaceous gland cystic epithelium, and the swelling is spherical in shape, resulting in painless and itchy buttocks long meatballs.
3. Lipoma: a tumor of normal fat-like tissue, which may be related to genetic and fat metabolism abnormalities and other reasons. The clinical manifestation is a painless lump of small size, resulting in painless and itchy buttocks.
It is recommended that patients should go to the hospital in time to clarify the cause of the disease and carry out treatment for long meatballs on the buttocks without pain or itching.
