OBJECTIVE: We report our clinical experience with malignant melanoma (MM) patients associated with neurological involvement. PATIENTS, MATERIALS AND METHODS: A database of patients admitted from 2014-2019 in the Ist Clinic of Neurology, Emergency County Hospital of Târgu Mureş, Romania, was reviewed to identify patients with MM and neurological involvement. We assessed the demographic and clinical data regarding the neurological disorders and the primary tumor characteristics from the patient registries. Both histopathological and immunohistochemical analysis of the neoplasm was available for the entire cohort. RESULTS: We analyzed 13 982 patient files and 21 met all the inclusion and exclusion criteria. Brain metastases were found in 38.09% of the patients, spinal metastases in 9.52% of the patients, ischemic stroke by cancer-associated thrombosis in 42.85% of the patients and peripheral nervous system involvement in 19.04% of the patients. No statistically significant differences between the four categories of neurological disorders according to socio-demographic parameters, location of the primary tumor, existence of primary tumor ulceration, invasion of the lymph nodes or the presence and location of distant metastasis was found (p>0.05). Our presented patient is the first case of uveal melanoma with hemorrhagic brain metastasis before hepatic involvement. CONCLUSIONS: Neurological involvement in MM encompasses a myriad of variants and while the clinical setting varies from one patient to another, an underlining neoplasia should be evaluated in suspected patients.
