What are the symptoms of hamartoma

Knowing more about the symptoms of hamartoma is very helpful for early detection and treatment of the disease, because most hamartomas (about 80% or more) grow in the peripheral part of the lung, close to the visceral pleura of the lung, and sometimes protrude from the surface of the lung, thus forming pulmonary hamartoma. Let me introduce to you what are the symptoms of hamartoma?

Most patients with hamartomas have no symptoms. The main reasons for the symptoms are mostly related to the location, size, number, growth rate, and relationship between the hamartoma and surrounding organs. During the physical examination, it is often found that some patients may have the following symptoms due to the tumor itself, increased pressure in the tumor, infection, etc.:

① Discomfort or pain in the waist and abdomen: The reason is that the enlarged and expanded kidney increases the tension of the renal capsule, pulls the renal pedicle, or compresses the adjacent organs. In addition, the large size of the renal hamartoma causes the kidney to become heavy, which can also cause lumbar pain. The pain is characterized by dull pain, fixed on one or both sides, radiating to the lower part and the waist and back. If there is bleeding in the tumor or secondary infection, the pain will suddenly intensify. If the urinary tract is blocked by stones or blood clots after bleeding, renal colic may occur.

②Hematuria: It can be manifested as microscopic hematuria or macroscopic hematuria. The attack is cyclical. The back pain often intensifies during the attack. Vigorous exercise, trauma, and infection can induce or aggravate it.

③Abdominal mass: Sometimes it is the main reason for patients to seek medical treatment. 60% to 80% of patients can feel enlarged kidneys.

④ Proteinuria: Generally, the amount is not much, and will not exceed 2g in 24 hours. Nephrotic syndrome will not occur.

⑤ Hypertension: The tumor compresses the kidneys, causing renal ischemia, increasing renin secretion, and causing hypertension. When renal function is normal, more than 50% of patients have hypertension, and the incidence of hypertension is even higher when renal function is impaired.

⑥ Decreased renal function: Due to the tumor's space occupation and compression, the normal renal tissue is significantly reduced and renal function progressively declines.

Since there are immature blood vessels in the components of hamartoma, the tumor may suddenly rupture and cause bleeding in the tumor. The patient will experience acute abdominal pain, and even shock if there is a lot of bleeding. Therefore, you must be vigilant when the above symptoms occur and go to the hospital for treatment in time. The doctor will evaluate the condition and closely monitor the changes in vital signs. If the bleeding is not much, conservative treatment and active monitoring can be used. If the bleeding is severe, emergency vascular interventional embolization treatment or even surgical removal of the kidney is required.
