What is the most common benign tumor of the spleen?

Can spleen tumor be benign?

Most common primary tumours of the spleen are benign and originate from the vascular endothelium and include haemangioma, hamartoma, littoral cell angioma, lymphangioma, haemangioendothelioma, haemangiopericytoma. Non-vascular tumours comprise the inflammatory pseudotumour, fibroma and lipoma [1–6].

What causes benign lesions on spleen?

SANT is a benign nonneoplastic vascular lesion of the spleen. This lesion is thought to arise from a response of the red pulp to underlying stromal inflammation or vascular injury. On pathology, there are dense areas of fibrosis and angiomatoid nodules. SANT usually presents as a solitary lesion.

Are spleen nodules common?

The most common malignant neoplasm of the spleen is lymphoma. Disseminated lymphomatous disease with spleen involvement is more common than primary splenic lymphoma. There are often multiple or diffuse nodules throughout the spleen and only rarely is a solitary splenic mass discovered.

What would a Mass on the spleen be?

A splenic tumor is a mass or lump within the spleen. Overall, two-thirds of all splenic masses are malignant and of these, two-thirds are hemangiosarcoma. If a patient presents with a splenic mass and internal bleeding, there is a 76% risk of having a malignant splenic tumor and 70% risk of having hemangiosarcoma.

Does a splenectomy affect life expectancy?

Which cancers cause enlarged spleen?

Blood cancers, such as leukemia and myeloproliferative neoplasms, and lymphomas, such as Hodgkin’s disease. Metabolic disorders, such as Gaucher disease and Niemann-Pick disease. Pressure on the veins in the spleen or liver or a blood clot in these veins. Autoimmune conditions, such as lupus or sarcoidosis.

What would cause a lesion on your spleen?

Etiologies for multifocal splenic lesions include infectious and inflammatory processes, primary vascular and lymphoid neoplasms, metastatic disease, vascular processes, and systemic diseases. There is often overlap in the imaging appearance alone, so the clinical setting is very helpful in differential diagnosis.

Do benign spleen tumors bleed?

Splenic tumors tend to bleed chronically and slowly – and usually insignificantly – prior to a large bleed that produces obvious symptoms.

Are lesions on the spleen serious?

Hypodense splenic lesions are frequently encountered on abdominal CT images. Although most hypodense lesions of the spleen can be considered benign, some findings and clinical conditions warrant closer attention to the lesion.

Where does spleen pain hurt?

Spleen pain is usually felt as a pain behind your left ribs. It may be tender when you touch the area. This can be a sign of a damaged, ruptured or enlarged spleen.

Can you have a tumor in your spleen?

Spleen cancers are typically secondary, meaning that they originate elsewhere and then spread to the spleen. The most common causes of spleen cancer are lymphomas and leukemias. On occasion, other cancers, such as breast, lung, stomach, pancreatic, liver, or colon, are the source of the malignancy.

Should I be worried about spleen lesions?

The presence of lesions in other organs in addition to the spleen should raise suspicion for metastases or metastatic primary splenic angiosarcoma. Rarely, patients with benign neoplasms may present with abnormal laboratory values, such as thrombocytopenia or anemia.
