A rare case of hard palate large B-cell lymphoma spontaneously regressed in a patient. This unusual presentation highlights the importance of thorough diagnosis for non-Hodgkin lymphomas.
Area of Science:
- Oncology
- Hematology
- Pathology
Background:
- Non-Hodgkin lymphomas can affect the upper aero-digestive tract.
- Large B-cell lymphoma of the hard palate is an exceptionally rare malignancy.
Observation:
- A 58-year-old female presented with a hard palate lesion.
- Imaging revealed invasion of the palatine canal.
- The lesion spontaneously resolved within 15 days post-biopsy.
Findings:
- Diagnosis confirmed as large B-cell lymphoma via lymph node biopsy.
- Positron emission tomography (PET) scan showed complete absence of the lesion.
- Spontaneous clinical regression of palatine lymphoma was observed.
Implications:
- This case underscores the variability in clinical presentation and disease course for lymphomas.
- Highlights the diagnostic challenges and the role of immunochemistry in rare lymphomas.
- Further research may explore mechanisms of spontaneous regression in B-cell lymphomas.
