Lacrimal tumors are a relatively rare disease of the lacrimal system. According to the literature, more than 55% of lacrimal tumors are malignant tumors. If the tumor cannot be completely removed or has already metastasized, it may increase the recurrence rate and mortality rate. Therefore, in clinical practice, if a case of a mass in the lacrimal sac is encountered, a thorough examination should be performed, such as orbital ultrasound scan, CT and MRI with or without contrast enhancement, and endoscopic examination of the lacrimal duct, if possible. The condition should be fully assessed to design a reasonable surgical approach and the extent of surgical resection. If the lesion is large or the condition is complex, a single incision through the skin or endoscopic approach may not be able to completely remove it, and an combined approach can be used to obtain a good view and fully dissect and separate the lesion for appropriate resection. This article reports two cases of lacrimal tumor resection performed through a skin incision combined with an endoscopic approach, one of which had a postoperative pathological diagnosis of benign papilloma and no recurrence was observed.5 months after surgery and Long-term follow-up is planned. The other case was NUT carcinoma. The patient had received chemotherapy in the oncology department of the general Hospital after diagnosis. It is suggested that the imaging examination of the orbit should be improved in the case of lacrimal tumor before operation, and the examination of the main organs of the body should be perfected when malignant tumor is suspected, so as to fully evaluate the condition. For the case with surgical indications, the appropriate surgical plan should be selected and the complete resection should be carried out as much as possible. Long-term follow-up should be carried out after surgery, so that recurrence and metastasis can be detected early, and timely treatment can be carried out.
