Utilizing medical thoracoscopy for the diagnosis of myelomatous pleural effusion: 2 case reports.

Multiple myeloma (MM) is characterized by neoplastic proliferation of monoclonal antibody producing plasma cells. In clinical practice, pleural effusion is seen in up to 6% of MM patients, with many causative factors. Nevertheless, true myelomatous pleural effusion, defined as infiltration of the pleura by myeloma cells, is very rare. In this case report, we present two patients with biopsy proven myelomatous pleural effusion. The first patient developed myelomatous pleural effusion as initial presentation while the second patient's pleural effusion occurred during disease relapse. In both cases, prompt diagnosis via medical thoracoscopy (MT) followed by early commencement of myeloma specific chemotherapy led to clinical, biochemical, and radiological resolution and therefore were crucial steps in the management of myelomatous pleural effusion.

Molecular testing for advanced non-small cell lung cancer in Malaysia: Consensus statement from the College of Pathologists, Academy of Medicine Malaysia, the Malaysian Thoracic Society, and the Malaysian Oncological Society.

In the recent years, increased understanding of the molecular profiles of non-small cell lung cancer (NSCLC) has allowed for targeted treatment of actionable genetic mutations. The management of NSCLC now requires multiple molecular tests to guide the treatment strategy. In the light of this, there is a need to establish a molecular testing consensus statement for advanced NSCLC patients in Malaysia. This Malaysian consensus statement was developed by a panel of experts, chaired by a pathologist and composed of three other pathologists, four respiratory physicians and three oncologists. It reflects currently available scientific data and adaptations of recommendations from international guidelines to the local landscape. Expert recommendations on different aspects of molecular testing agreed upon by the panel are provided as structured discussions. These recommendations address the appropriate patients and samples to be tested, as well as when and how these tests should be performed. The algorithms for molecular testing in metastatic NSCLC, in the first line setting and upon disease progression beyond first line therapy, were developed.

Human pentastomiasis caused by Armillifer moniliformis in Malaysian Borneo.

We report a case of visceral pentastomiasis caused by Armillifer moniliformis in a 70-year-old aboriginal farmer from rural Malaysian Borneo. The patient complained of upper abdominal pain, jaundice, and loss of weight. Radiological investigations and subsequent histopathological examination revealed an adenocarcinoma of the pancreas with an adjacent liver nodule containing a nymph of A. moniliformis. This report constitutes the first documented human pentastomid infection in the whole of Malaysia after nearly 40 years, and it is the third description from Malaysian Borneo. Cases of human and animal pentastomiasis in Malaysia are discussed.
