What causes a lump to grow at the anal opening?

Under normal circumstances, the appearance of a fleshy lump near the anus may be caused by congenital skin folds, sebaceous gland secretions, hemorrhoids, perianal abscess, or anal fistula. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. The specific analysis is as follows:

1. Congenital Skin Folds

The skin around the anus naturally has folds and small elevations. When these folds or protrusions become more prominent, they may be mistaken for abnormal lumps. It is advisable to keep the anal area clean and dry, avoid friction and irritation, and use mild cleansing products to help reduce discomfort.

2. Sebaceous Gland Secretions

Sebaceous glands in the skin around the anus may form small fleshy lumps due to accumulation of secretions. Maintaining local hygiene and avoiding squeezing are recommended. Warm compresses may be used when necessary to promote spontaneous resolution of the cyst.

3. Hemorrhoids

Hemorrhoids may be caused by prolonged sitting or standing, dietary factors, and other reasons. They can lead to protruding fleshy tissue—appearing as lumps—around the anus, often accompanied by symptoms such as anal pain, bleeding, and itching. Symptomatic treatment may include medications such as Ma Ying Long Musk Hemorrhoid Ointment, Pujin Hemorrhoid Suppositories, or Yunnan Baiyao Hemorrhoid Ointment, as directed by a doctor.

4. Perianal Abscess

A perianal abscess is usually associated with infection, involving pus formation in the soft tissues surrounding the anus. It typically presents as a lump near the anus, accompanied by redness, swelling, and pain. Under professional medical guidance, antibiotics such as Levofloxacin Hydrochloride Capsules, Metronidazole Tablets, or Amoxicillin Capsules may be prescribed for treatment.

5. Anal Fistula

An anal fistula develops when an infection or inflammation inside the anal canal penetrates through the anal sphincter muscle to the skin surface, forming an abnormal tunnel (fistula). The external opening of the fistula often exhibits granulation tissue overgrowth, which may appear as a fleshy lump, and may be associated with symptoms such as anal pain and discharge with odor. Under medical supervision, medications such as Tinidazole Tablets, Cefaclor Tablets, or Ornidazole Tablets may be used to alleviate symptoms.

In daily life, maintaining moderate physical activity, getting adequate rest, and reducing stress are beneficial for overall health.
