Abstract

Peripheral T-cell lymphoma is a rare type of lymphoma that's derived from postthymic lymphoid T cells. Pulmonary involvement of peripheral T-cell lymphoma of the unspecified type is very rare and the imaging findings of this illness have rarely been reported. We present here a case of peripheral T-cell lymphoma of the unspecified type with a cavitary lesion in the lung parenchyma, and we pathologically confirmed this illness by performing video-assisted thoracoscopic surgery.

Figure

  Fig. 1 A. The initial chest X-ray of a 39-years-old male shows a thin-walled cavitary lesion (arrow) in the left middle lung zone. B. The chest CT images show a thin-walled cavitary lesion with a speculated margin in the superior segment of the left lower lobe. C. The chest X-ray after 2 months shows consolidation (arrows) in the left middle lung zone. D, E. The follow-up CT scan shows a thick-walled cavitary lesion, which has enlarged as compared to that seen on the previous chest CT scan in Figure 1B. An irregular diffuse infiltration in the mediastinal fat is visualized with a poorly defined lymph node (arrow) (E). F. Grossly, the cut specimen shows parenchymal necrosis and hemorrhage with a cavitary lesion. G. The microscopic image shows a cavitary lesion and dilated vessels with surrounding hemorrhagic necrosis (hematoxylin and eosin staining, ×40). H. Immunohistochemical staining for CD 3 (T cell marker) gives a positive reaction.
