We report on three resected cases of intrapulmonary plasma cell granuloma. All of them were asymptomatic. One of them showed bilateral multiple lesions and in this case bilateral partial resections of lung in one stage were performed. Under light and electron microscopy the lesions were composed of plasma cells and other kinds of inflammatory cell. The plasma cells were mature and had rich endoplasmic reticulum but no kind of intracytoplasmic inclusion. Steroid therapy was effective for the recurrent lesion after the operation.

We recently encountered a case of intrabronchial neurilemmoma. The patient was a 15-year-old boy who had a wheeze. After observation with a bronchofiberscope, a wedge resection of the left main bronchus was performed. No postoperative complications nor recurrence was seen. To date, five cases of intrabronchial neurilemmoma have been reported in the Japanese Journals. Surgical removal was performed in 4 of 5 and bronchofiberscopic excision in 1. This paper summarizes the clinical features of these cases as well as our own case.

A 74-year-old womanwith erythropoietic protoporphyria (EPP) with hepatic dysfunction is reported. She had been photosensitive for two years prior to admission. Physical examination revealed hepatosplenomegaly and erosions on her face. Moderate increases in serum bilirubin and biliary tract enzymes were noted. Histology of the biopsied liver revealed moderate fibrosis and dilatation of bile canaliculi containing orange pigment. Marked increases in protoporphyrin in erythrocytes and feces were noted. The patient died of hepatic failure a year and a half after admission with maximumserum bilirubin of 34 mg/dl. This patient seems to be the oldest among reported EPP cases with liver dysfunction.
