Contrast-enhanced computed tomography (CT) scan showed a 4.2 x 3.2 cm, heterogeneous noncalcified mass involving most probably the right adrenal gland region (Figures 1(a) and 1(b)).
Microscopic examination of pleural mass (hematoxylin and eosin [H&E] stain). (a) Encapsulated mass with marked myxoid changes. (b) Monomorphic spindled Schwann cells forming cellular Antoni A areas with nuclear palisading and Verocay bodies alternating with hypocellular myxoid area. (c) Schwann cells with inconspicuous cytoplasm and nuclei suspended in myxoid matrix and areas of typical perivascular hyalinization.
