A sixty year old woman presented with a tumor of the caruncle that had persisted for one year. Ophthalmologic history was unremarkable. Physical examination disclosed an indolent, tight elastic, highly vascularizated tumor. The lesion measured five millimeter in diameter. Histopathology revealed tall columnar cells with small round nuclei. The cytoplasm stained positive with hematoxylin and eosin. The typical histopathologic features were consistent with an oncocytoma.
Tumors of the caruncle are very heterogenous because the caruncle contains tissues of the conjunctiva and the epidermis. Therefore to exclude a malignant process an excisional biopsy should always be performed even so in general tumors of the caruncle are benign. The most frequent tumors of the caruncle are papilloma, nevi, pyogenic granuloma, epithelial inclusion cyst and chronic inflammation. In only 4 % of the cases oncocytomas are found even the oncocytoma is considered to be a typical tumor of the caruncle.
一名60岁女性，其泪阜肿物已持续一年。眼科病史无异常。体格检查发现一个生长缓慢、质地坚韧、弹性良好且血管丰富的肿物。该病变直径为5毫米。组织病理学显示为高柱状细胞，核小而圆。细胞质苏木精-伊红染色呈阳性。典型的组织病理学特征符合嗜酸细胞瘤。
泪阜肿瘤具有高度异质性，因为泪阜包含结膜和表皮组织。因此，即使泪阜肿瘤通常为良性，为排除恶性病变，也应始终进行切除活检。泪阜最常见的肿瘤是乳头状瘤、痣、化脓性肉芽肿、上皮包涵囊肿和慢性炎症。即使嗜酸细胞瘤被认为是泪阜的典型肿瘤，其在病例中仅占4%。
