Mesothelioma synonyms

Mesothelioma, formally known as malignant mesothelioma, is an aggressive form of cancer that develops in the thin layer of tissue covering most internal organs, known as the mesothelium. While it is most commonly referred to by this name, it may occasionally appear in older medical records or international literature as pleural endothelioma or mesothelioma of the pleura, depending on the site of origin.

What are the primary names and synonyms for Mesothelioma?

In modern clinical practice, mesothelioma is the standard term used by oncologists and pathologists worldwide. However, because the disease can originate in different serous membranes, medical records may sometimes specify the location, leading to variations in naming. The most common synonym is malignant mesothelioma. Historically, you may encounter terms such as pleural endothelioma, which reflects older theories regarding the cell of origin, or diffuse malignant mesothelioma, which describes the invasive growth pattern of the cancer. Because mesothelioma can develop in the lining of the lungs (pleura), abdomen (peritoneum), heart (pericardium), or testes (tunica vaginalis), these specific anatomical locations are often appended to the primary diagnosis to ensure clinical clarity.

How is Mesothelioma classified in medical systems?

Standardized medical coding systems provide specific identifiers to ensure consistency across global healthcare systems. In the International Classification of Diseases (ICD-10 and ICD-11), mesothelioma is categorized primarily under codes related to malignant neoplasms of the mesothelium. Orphanet, the reference portal for rare diseases, classifies it under ORPHA:573. In the Online Mendelian Inheritance in Man (OMIM) database, while mesothelioma is primarily an acquired malignancy related to environmental exposure—most notably asbestos—it is indexed as #156240 when discussing the rare hereditary predisposition to the disease, often linked to BAP1 tumor predisposition syndrome.

Why does Mesothelioma have multiple names?

The nomenclature of mesothelioma has evolved alongside our understanding of tumor biology. Historically, the term "endothelioma" was used because researchers believed the tumor arose from the endothelium (the lining of blood vessels). As pathology advanced, experts confirmed that the tumor originates from the mesothelium, leading to the adoption of the current, more accurate name. Furthermore, the disease is sometimes categorized by its histological subtype, such as epithelioid, sarcomatoid, or biphasic mesothelioma. These descriptors are not synonyms but are essential sub-classifications that dictate prognosis and treatment pathways.

Common terms and abbreviations for Mesothelioma

When reviewing medical documentation, you may encounter the following terms and abbreviations used in clinical settings:

• Malignant Mesothelioma (MM): The most common, precise medical term.


• Pleural Mesothelioma: Refers to the cancer occurring in the lining of the lungs (the most frequent site, accounting for approximately 75-80% of cases).


• Peritoneal Mesothelioma: Refers to the cancer occurring in the abdominal lining.


• Pericardial/Tunica Vaginalis Mesothelioma: Rare forms occurring in the heart or testicular lining, respectively.


• Diffuse Malignant Mesothelioma: A term used to describe the tumor’s tendency to spread across the surface of the affected organ.

Next steps

• Consult a thoracic surgeon or an oncologist specializing in mesothelioma to interpret specific pathology reports and staging.


• Request a second opinion from a dedicated mesothelioma treatment center, as specialized care significantly impacts outcomes.
