Primary nasal diffuse large B-cell lymphoma with synchronous pulmonary involvement: A case report
We report a case of primary nasal DLBCL who presented with a mass in the left lower lobe, mimicking primary lung carcinoma.
Patient concerns:
A 62-year-old Chinese female visited the Ear-Nose-Throat Department of our hospital with nasal congestion and rhinorrhea for 2 months.
Diagnosis:
Computed tomography scan revealed a mass with soft tissue density in the left vestibule and nasal cavity. Histopathological examination revealed a large number of lymphoma cells, and immunohistochemistry confirmed the diagnosis of DLBCL.
Interventions:
The patient was treated with 6 cycles of R-CHOP (cyclophosphamide, adriamycin, vincristine, prednisone, and rituximab).
Outcomes:
The treatment was well tolerated and led to complete remission for the patient. There was no sign of relapse over the 3-year close follow-up
Lessons:
DLBCL can be present at various extranodal sites and clinicians irrespective of their specialty must be vigilant for the synchronous mode of presentation of such lesions. Immunohistochemical techniques play a vital role in the diagnosis, because clinical characteristics may be misleading.
