Introduction: Gelatinous transformation of the bone marrow (GTBM) represents a clinically significant but often underdiagnosed condition, emphasizing the pivotal role of accurate diagnosis in facilitating appropriate treatment strategies.
Areas covered: This special report synthesizes insights gathered from a comprehensive appraisal of clinical and pathology publications on GTBM available on PubMed. By employing search terms such as 'gelatinous,' 'gelatinous transformation,' and 'bone marrow,' this report aims to provide a nuanced understanding of GTBM, elucidating distinctive pathological features while distinguishing it from similar pathologies. The review also discusses currently identified causes of GTBM, clinical, imaging, pathologic, and laboratory findings that are associated with GTBM, and treatment options available.
Expert opinion: Contrary to popular belief, we suggest that nutrient deficiency is not solely responsible for the pathogenesis of GTBM and that malignancies, infection, and inflammatory conditions play a critical role in its pathogenesis. We propose that further research on the pathophysiology of GTBM should be performed to unravel the complex interplay of nutritional and inflammatory factors in hematopoiesis, paving the way for innovative treatment approaches in hematopoietic disorders. To better facilitate further research in GTBM, we suggest formulating a pooled patient database with nutritional, genetic, and cytokine markers in a prospective fashion.
