Histopathological examination and immunohistochemical analysis ultimately confirmed the diagnosis of primary oral MALT lymphoma. This case emphasizes the importance of thorough evaluation in distinguishing between benign and malignant oral lesions.
What made this case unusual
The primary occurrence of MALT lymphoma in the oral cavity is exceedingly rare, making this case noteworthy for its atypical presentation.
Diagnostic / clinical pearl
Clinicians should be aware that oral lymphoid proliferations can mimic benign lesions, necessitating careful histopathological and immunohistochemical evaluation for accurate diagnosis.
Why it matters
This case underscores the diagnostic challenges of oral lymphoid lesions and the need for clinicopathological correlation to ensure appropriate management.
