A computed tomography (CT) scan of his chest 3 days later (January 4, 2018) revealed bilateral pleural effusion and multiple mediastinal lymphadenopathies (Figure 1).
Follicular lymphoid hyperplasia and focal, circumscribed, paracortical necrotizing lesions, composed of abundant karyorrhectic debris, scattered fibrin deposits, and collection of large mononuclear cells (lymph node x 600).

Pathologic studies of the mediastinal lymph nodes showed follicular lymphoid hyperplasia and focal, circumscribed, paracortical necrotizing lesions composed of abundant karyorrhectic debris, scattered fibrin deposits, and a collection of large mononuclear cells (Figure 2).
Immunohistochemically, the large mononuclear cells are positive for myeloperoxidase (lymph node x 600).

The overall histopathology indicated a necrotizing adenitis process and was compatible with Kikuchi`s lymphadenitis (Figure 3).
Necrotizing inflammation of the pleural tissue and some lymphoid tissue with necrotizing lesions, composed of abundant karyorrhectic debris (pleura x 600).

Pathologic studies of the right pleura revealed necrotizing inflammation of the pleural tissue and some lymphoid tissue with necrotizing lesions, composed of abundant karyorrhectic debris with similar changes as in the mediastinal lymph nodes (Figure 4).
