Paranasal Diffuse Large B-Cell Lymphoma with Orbital Invasion Presented with Acute Sinusitis, Orbital Cellulitis

Purpose: To report a case of paranasal diffuse large B-cell lymphoma with orbital invasion that presented with acute sinusitis and orbital cellulitis. Case summary: A 78-year-old man presented with right periorbital swelling that stated 2 days after after gingival abscess treatment 2 weeks ago. Under suspicion of acute sinusitis and orbital cellulitis, systemic antibiotics and anti-inflammatory medication was started but the symptoms worsened. We performed incisional biopsy of orbital lesion via transcaruncular approach. Based on histopathological examination, the orbital mass was diagnosed as diffuse large B-cell lymphoma. Conclusions: We report the case of paranasal lymphoma with orbital extension presenting with acute sinusitis and orbital cellulitis from gingival abscess history and acute onset. This condition should be considered for patients with acute sinusitis and orbital cellulitis that aggravates for a short period of time.
