“…The case reported is a localized lesion in the jaws, and we opted for biopsy and histopathology to define the diagnosis. But it is also important to evaluate the prognosis in these cases, and one factor to consider is serum lactate dehydrogenase (LDH), as a result of the reversible conversion of muscle lactic acid into pyruvic acid, this change being accomplished by the catalysis of LDH, and is found in various tissues of the human body and only a lesion characterized by cells can raise the levels of this marker, Unfortunately, it was not possible to determine the value of LDH in this patient, but other reports show that although LDH is predictive of prognosis, in some situations its values may permeate within the reference for normality, indicating that this enzyme has limited diagnostic value (DOS SANTOS et al, 2022).…”
