Background: While brain metastases (BM) are the most common causes of neurologic disorders in patients with known systemic malignancies, they can often be the initial manifestations of an undetected primary elsewhere. BM are major causes of morbidity and mortality in cancer patients. Aims: We describe a mixed population (data from both retrospective and prospective collection) having a BM from a solid tumor. We report the percentage distribution of the most frequent types of BM, confirming the data published in the literature. This paper may play a role in presenting the Southeast Asian reality compared with the Western countries. Setting: A tertiary-care cancer centre. Materials and Methods: Data for 4 years were retrieved from the records of the Department of Pathology of our institute. Hematolymphoid and meningeal tumors were excluded. Hematoxylin and eosin (H and E) stained slides were reviewed, and in cases with an unknown primary, immunohistochemistry (IHC) was advised. The panel of markers was chosen based on the histomorphology on H and E sections. IHC was done in cases with an unknown primary where paraffin blocks were available. Results: Lung cancer was found to be the most common primary malignancy (n = 30; 48.4%) followed by breast cancer (n = 13; 21%), colorectal cancer (n = 6; 9.6%), and skin cancer (melanoma) [n = 3; 4.8%]. Conclusion: The incidence of BM from lung and breast cancer was similar to that seen in the Western studies. However, BM from colorectal cancer and melanoma show a higher and lower incidence, respectively, in comparison with the Western literature.
