Primary Diffuse Leptomeningeal Melanomatosis in an Indian Child With Review of Literature.
Kumar et al., Pediatr Neurol 2023
DOI: 10.1016/j.pediatrneurol.2023.12.007
New Insights:
This case report introduces the first pediatric case of Primary diffuse leptomeningeal melanomatosis (PDLM) from India, contributing to the limited global case data on this rare condition. It emphasizes the diagnostic challenges of PDLM, which can mimic tuberculous meningitis (TBM), leading to misdiagnosis and inappropriate treatment.
Importance:
The report is significant as it adds to the scant literature on PDLM in children, with only 15 pediatric cases reported so far. It highlights the need for heightened clinical suspicion and alternative diagnostic approaches when standard treatments fail.
Contribution to Literature:
The case underscores the importance of considering PDLM in the differential diagnosis of persistent central nervous system symptoms unresponsive to typical therapies. It suggests that targeted molecular diagnosis and precision medicine could potentially improve outcomes in pediatric PDLM, a notion that may guide future research and clinical practice.
Summary of Results:
A 12-year-old male with symptoms mimicking TBM underwent various treatments without improvement. MRI findings and a lack of malignant cells in cerebrospinal fluid complicated the diagnosis. However, a biopsy revealing blackish deposits and histopathological examination confirmed PDLM. Despite the diagnosis, the patient expired 4 months later.
