Abstract
A case of thoracic pseudolymphoma diagnosed after operation is described.
A 65-year-old male was pointed out on abnormal shadow on chest X-P for medical checkup. The tumor of thorax was excised. Based on the examination of the excised specimen, it was diagnosed as pseudolymphoma. There has been no recurrence of tumor, as of one year after the operation.
It has been reported that pseudolympoma occurs in various organs such as the lung, skin, and salivary gland. No report of pseudolymphoma arising in the chest wall can be seen in the literature. Histologically it mimics extranodular lymphoma, but infiltrated lymphocytes are of low grade malignancy. The prognosis is good. However, we have difficulties in preoperative differential diagnosis. In view of this fact, it is better to select surgical excision first, however, we can select conservative therapy if the tumor is small and no clinical manifestations develop. At any rats strict follow-up should not be neglected.
