There are many reasons for the appearance of hard lumps under the raphe, considering skin lesions, bone hyperplasia, congenital abnormal raphe development, digestive system tumors and other reasons. 1. Skin lesions: when certain skin lesions occur under the raphe, they can cause hard lumps under the raphe, such as lipoma, fibroma, etc. Generally, there are no obvious symptoms, no pressure pain, and surgical resection can be chosen after diagnosis. 2. Bone hyperplasia: Calcium salts are abnormally deposited in the subxiphoid process due to various reasons, which causes localized bone hyperplasia in the subxiphoid process, resulting in the appearance of hard lumps. 3. Congenital abnormal development of the raphe: if the raphe cartilage develops abnormally congenitally, a hard lump can be touched under the raphe. 4. Tumor of digestive system: some patients with gastric cancer or liver cancer may be able to palpate the hard lump 5cm below the xiphoid process, but the patients are often accompanied by other symptoms, such as dyspepsia, abdominal distension, cachexia, etc. In addition, some patients with high location of intestines may be able to palpate the hard lump at the xiphoid process. In addition, subxiphoid hard mass can also be found in certain high position intestinal obstruction. When there is a subxiphoid hard lump, consult a doctor in time to clarify the cause of the disease and treat it as soon as possible.
