The presented case, a 60-year-old female, was ultimately diagnesed as pseudolymphoma after right upper lobectomy with a tentative diagnosis of lung cancer, although repeated transbronchial as well as percutaneous biopsy procedures all failed to reveal presurgical histological and cytological confirmations. The tumor, ca 2×2cm in size, was localized immediately beneath the pleura in right upper dorsal segment. Though the tumor showed marginal infiltrative extensions into the surrounding normal pulmonary tissue with a small indentation of pleura and its gross appearance was very much like adenocarcinoma, no metastases were confirmed in the regional lymphonodes. Histologically, the tumor was a localized hyperplasia of lymphoid tissue with prominent germinal centers. Proliferation of collagenous tissue was also evident. The lymphocytes, plasma cells, and scattered hystiocytes appeared normal in morphology without any atypy. The patient has been on followup for one year and four months without relapse after the resection. Twenty cases of pseudolymphoma hitherto reported in Japanese literatures, including the present case, were analysed. These cases demonstrated a benign nature of the condition as a whole, although a few exacerbations of residual lesions were reported. Strict adherence to criteria for the diagnosis and long-term followup appear to be necessary in the present status for dealing with pseudolymphoma.
