Post-Inflammatory Pseudotumor (Plasma cell Granuloma と Histiocytoma) の2症例

抄録

Plasma cell granuloma has been reported under several synonyms since the first report by Brunn in 1939.
It is a rather rare disease, but the number of reported cases in Japan has been increasing in recent years.
Differential diagnosis from malignant neoplasm on the basis of clinical and radiological finding is difficult and diagnosis was established after surgical procedures in all cases.
Two cases of post-inflammatory pseudotumor, one case of plasma cell granuloma, and another of histiocytoma, are reported here with the histopathological and immunocyte-chemical findings. Fifty five reported cases in the world literature were reviewed, with special reference to their clinical and histopathological findings.
