松山赤十字病院における涙腺部腫瘍の検討

Review of lacrimal gland tumor at Matsuyama Red Cross Hospital

要約　目的：松山赤十字病院で診断した涙腺部腫瘍の報告。

対象と方法：過去139か月間に病理組織診断が確定した涙腺部腫瘍68例を対象とし，年齢，性差，治療法とその成績を検討した。

結果：良性腫瘍45例（66％），悪性腫瘍23例（34％）であり，良性腫瘍については，男性16例，女性29例であり，悪性腫瘍については，男性13例，女性10例であった。上皮性腫瘍は，多形腺腫，囊胞，癌腫の順に多く，リンパ増殖性腫瘍は，悪性リンパ腫，非IgG4関連疾患，IgG4関連疾患の順に多かった。

結論：涙腺由来と推定される腫瘍では，悪性腫瘍の頻度が1/3を占めていた。涙腺腫瘍では，悪性腫瘍を念頭に置いて検査と治療を進める必要がある。

Abstract　Purpose: To present a review of tumors in the lacrimal fossa diagnosed at Matsuyama Red Cross Hospital.

Cases and Method: This study was made on 68 cases of lacrimal gland tumor in the past 139 months. All the cases had been pathologically diagnosed. Cases were evaluated regarding age, sex, method of treatment, and therapeutic outcome.

Findings: There were 45 cases of benign tumor（66％）and 23 cases of malignant tumor（34％）. There were 16 males and 29 females diagnosed with benign tumor. There were 13 males and 10 females diagnosed with malignant tumor. Among epithelial tumors, pleomorphic adenoma was the most frequent, followed by dacryops and carcinomas. Among lymphoproliferative tumors, malignant lymphoma was the most frequent, followed by non-IgG4-related diseases and IgG4-related diseases.

Conclusion: One-third of malignancy in the lacrimal fossa comprised malignant tumors. Due attention is advocated to this feature when dealing with tumors of lacrimal gland area regarding diagnosis and treatment.
