Neck findings of Patient 13. (D) Diffuse swelling of the right neck without overlying erythema or ulceration. (E) Neck MRI shows multiple enlarged lymph nodes in the right retropharyngeal lateral group, within the parotid gland, and on both sides of the neck. (F) Histopathology (H&E staining, 10×) reveals infiltrates of plasma cells and neutrophils, consistent with chronic suppurative inflammation.
