On gross inspection, the resected tumor measured 7.8 cm in size (Figure 2).
Histopathological examination showed (A) preserved lymph node architecture with a capsule, (B) surrounded by peripheral lymphocytes in concentric circles, (C) interfollicular vascular proliferation with perivascular hyalinization and plasma cells and histiocytes infiltration.

Microscopic examination demonstrated preserved lymph node architecture with a capsule, surrounded by peripheral lymphocytes in concentric circles, interfollicular vascular proliferation with perivascular hyalinization, plasma cells, and macrophage infiltration (Figure 3).
(A) Preparative computed tomography scan showed that the mass close to the main pulmonary artery bifurcation and extended along the right pulmonary artery. (B) Postoperative computed tomography scan showed no residual and no recurrence of the tumor.
