The clinical presentation of mesothelioma is rather insidious and a very late diagnosis is made in most patients due to the nonspecific nature of complaints [1] [2]. It is established that up to 4 months pass from the onset of symptoms before the tumor is recognized [3], which significantly reduces survival rates. Mesotheliomas are much more likely to occur in men, primarily due to its association with occupational exposure to asbestos and other known carcinogens (the male-to-female ratio is established at 5:1) [2] [4]. The clinical presentation depends on the location of the tumor, with the two main locations being the pleura (the most common) and the peritoneum [1] [2] [3] [4]. In the majority of cases suffering from pleural mesothelioma, a nonproductive cough that is often accompanied by dyspnea, fatigue, diaphoresis, and focal chest pain in some people are notable complaints [1] [2] [5]. Rarely, scoliosis toward the ipsilateral side or splinting may develop due to the expansive nature of the tumor [1]. Conversely, abdominal pain, swelling, anorexia, profound losses in body weight, as well as ascites are manifestations of peritoneal mesothelioma [3]. In some patients, the diagnosis is made incidentally [3].

• Pain

  Typical symptoms are nonspecific, such as a nonproductive cough, dyspnea, and localized chest pain in the case of pleural mesothelioma, whereas abdominal pain, anorexia, weight loss, and swelling of the abdomen are reported with peritoneal tumors. [symptoma.com]

  Persistent pain in the chest and shortness of breath are the most common symptoms of mesothelioma. [msdmanuals.com]

  The procedure involves heating some of the pain nerves in the spinal cord that transmit pain information to the brain. [mesothelioma.uk.com]

  Over half of patients with pleural mesothelioma have pain in the lower back or at the side of the chest. An increase in waist size or abdominal pain may be a symptom of the growth of cancer cells in the abdomen and peritoneal mesothelioma. [asbestosnetwork.com]

• Severe Pain

  If mesothelioma spreads to the chest wall or other nearby structures in the chest, the person may have severe pain, hoarseness, difficulty swallowing, a drooping eyelid, weakness and loss of sensation in an arm or hand, or swelling of the abdomen. [msdmanuals.com]

  Pleural mesothelioma symptoms include shortness of breath, chest pain, difficulty breathing, malaise, and fatigue. Severe pain occurs when cancerous mesothelioma cells grow and spread to the lining of the lungs. [baronandbudd.com]

  There may be severe pain caused by progression of the cancer into the chest wall and nerve fibers may contribute as well, and lead to poor sleep hygiene further aggravating the problem. [foundation.chestnet.org]

• Pleural Effusion

  Chest X-ray showed mediastinal widening with nonhomogenous opacity mainly in the periphery of right upper and mid zone with right-sided pleural effusion. Ultrasonography thorax confirmed mild pleural effusion. [ncbi.nlm.nih.gov]

  Computed tomography scan of the chest reveals a nodular pleura-based mass without pleural effusion surrounding the right lung. Figure 2. [jaoa.org]

  This fluid buildup is known as pleural effusion. What Is Pleural Effusion? One main symptom of mesothelioma is a buildup of the fluid between the parietal pleura and the visceral pleura. This buildup is called pleural effusion. [mesotheliomasymptoms.com]

• Aspiration

  This can be done with: Blood tests Biopsy: fine-needle aspiration biopsy; thoracoscopy; thoracotomy; laparotomy; open biopsy Cytologic exam (performed by a pathologist who examines cells from the biopsies) Treatment Pleural mesothelioma is usually treated [uvahealth.com]

  Because pleural cytology is not useful in the case of mesothelioma, fine-needle aspiration biopsy (FNAB), often guided by CT, or video-assisted thoracoscopy (which shows superior results compared to FNAB) are viable techniques that are used in practice [symptoma.com]

  Dysphagia can also occur but this is a late finding. Unlike bronchogenic carcinomas, presentation with haemoptysis, lymphadenopathy and metastatic symptoms are unusual. [ojrd.com]

• Abdominal Bloating

  Mesothelioma tumors can create fluid buildup in the peritoneum (ascites), causing symptoms like stomachaches and abdominal bloating. Pericardial Mesothelioma Pericardial mesothelioma is the least common form of mesothelioma. [mesotheliomaveterans.org]

  Symptoms of peritoneal mesothelioma include abdominal bloating, nausea, constipation and diarrhea. These common symptoms start off mildly, but as the lining of the abdomen thickens, tumors develop and symptoms become more noticeable. [asbestos.net]

• Chest Pain

  Typical symptoms are nonspecific, such as a nonproductive cough, dyspnea, and localized chest pain in the case of pleural mesothelioma, whereas abdominal pain, anorexia, weight loss, and swelling of the abdomen are reported with peritoneal tumors. [symptoma.com]

  Typical presenting features are chest pain and dyspnea. Breathlessness due to a pleural effusion without chest pain is reported in about 30% of patients. [orpha.net]

  Mesothelioma Symptom Chest Pain There are many causes of chest pain. A serious form of chest pain is angina, which is a symptom of heart disease and results from inadequate oxygen supply to the heart muscle. [medicinenet.com]

• Confusion

  Prior to the ICD-10 coding system, which assigns mesothelioma a specific code, mesothelioma deaths were coded according to their anatomical site and therefore often confused with lung and other cancers. [web.archive.org]

  It is also important not to confuse mesothelioma with lung cancer. Risk Factors Research is increasing regarding what we know about mesothelioma. Scientists are learning more about its causes. [cancersupportcommunity.org]

  The latency of mesothelioma symptoms causes confusion with physicians who have limited experience with this rare cancer. Seeking consultation and treatment from a specialist is critical. [mesotheliomaveterans.org]

The diagnostic workup should start with a meticulous clinical assessment. A detailed history must cover the onset of symptoms and their progression, as well as occupational details and whether exposure to asbestos or other harmful chemicals exists. During the physical examination, dullness on percussion due to a pleural effusion or diminished breathing sounds may be detected in the case of pleural mesotheliomas [1], in which case imaging studies need to be employed. Although plain radiography is a useful first-line study for the evaluation of the chest, more advanced studies, such as computed tomography (CT), magnetic resonance imaging (MRI), endoscopic ultrasonography (EUS), mediastinoscopy, laparoscopy, and positron emission tomography (PET) are recommended, primarily because they are able to determine the stage and aid in designing the optimal therapeutic strategy [1] [2] [3] [6]. To make a definite diagnosis, however, a sample of the tumor must be obtained for a histopathological examination. Because pleural cytology is not useful in the case of mesothelioma, fine-needle aspiration biopsy (FNAB), often guided by CT, or video-assisted thoracoscopy (which shows superior results compared to FNAB) are viable techniques that are used in practice [1] [2]. Immunohistochemical staining should include calretinin, as it carries a sensitivity rate of 95% and a specificity rate of 87% [2]. Other important markers are cytokeratin, mesothelin, and D2-40 [1] [2] [7].
