In four patients who showed a sharply bordered semi-circular clouding raising from the bottom of the maxillary sinus on x-ray, allergological tests and determination of serum immunoglbglin were performed. Caldweell-Luc operation was performd and in all of them hemispheric cyst bulding from the bottom of the maxillary sinus was recognized, which corresponded to the semi-circular clouding on x-ray. A histological study of mucous membrane of the maxillary sinus was performed. In one of them protein-compositions and sub-fraction of immunoglobulin of the fluid in the cyst were observed.
Results were summarized as follows:
1. Judging from the results of the tests, three of them presumably had relation to atopic allergy, and in two of them mucous membrane of the maxillary sinus showed infiltration of eosinophilic leukocyte.
2. Histological feature of mucous membrane of the maxillary sinus belonged to oedema-infiltration type according to Manasse's classification, and in three of them infiltration of plasma cell was more dominant than that of lymphocyte, and in the other in which lymphocyte was more dominant than plasma cell, growth of granulation was recognized.
3. Fluid in the cyst was exudate which contained same amount of total protein and albumin as in serum, but concentration of r-G in the exudate was much higher than that in serum as well as IgG and IgA, but IgM and other globulins were less in cyst than in serum.
4. Upper wall of the cyst had epithelium only on the side faced to the sinus, and no epithelium was recognized on the side faced to the cavity of cyst.
5. It was presumed that the cyst was formed by accumulation of the exudate in proper layer of mucous membrane of the maxillary sinus.
