What causes a hard lump in the center of the chest (xīnkǒuwō)?

A hard lump in the center of the epigastric region (the area just below the sternum, commonly referred to as the “upper abdomen” or “pit of the stomach”) may be associated with lipoma, sebaceous cyst, or fibroma.

What causes a hard lump in the center of the epigastric region?

1. Lipoma

Lipoma is a common benign tumor arising from adipose tissue. It typically occurs on the trunk, limbs, or within the abdominal cavity—and may also manifest as a hard lump in the center of the epigastric region. If the lipoma measures less than 1 cm in diameter, no specific treatment is usually required. However, if it exceeds 1 cm, laser therapy may be recommended for removal.

2. Fibroma

Fibroma is a benign tumor originating from fibroconnective tissue. It may result from genetic predisposition or physical factors. It commonly presents as a firm, well-defined, smooth-surfaced nodule in the epigastric region. Surgical excision using a rotary scalpel (e.g., a specialized minimally invasive device) is an effective treatment option.

3. Sebaceous Cyst

A sebaceous cyst develops due to obstruction of the sebaceous gland duct. It typically appears as a round, firm swelling and may present as a hard lump in the epigastric region. Surgical removal is the standard treatment. During recovery, maintain local skin cleanliness and avoid scratching or manipulating the lesion. Wearing loose, breathable clothing is also recommended to facilitate healing.
