Pleomorphic adenocarcinoma of lacrimal gland?

summary

Pleomorphic adenocarcinoma of the lacrimal gland, also known as malignant mixed tumor of the lacrimal gland, its clinical manifestations are similar to benign pleomorphic adenoma, with benign and malignant cell characteristics in histology. Let's share my experience with you.

Pleomorphic adenocarcinoma of lacrimal gland?

The clinical manifestation of pleomorphic adenocarcinoma is similar to pleomorphic adenoma, but the course of disease is short. The average course of lacrimal gland malignant tumor is 1.66 years, and the tumor often shows infiltrative growth because of no capsule. The clinical manifestations were extraorbital supraorbital adhesive mass with unclear boundary, tenderness and eyeball moving inward and downward.

The clinical symptom of malignant tumor is pain. Wright reported that the main clinical manifestations of lacrimal gland malignant mixed tumor were orbital mass (83%), eyeball displacement (67%), and pain (33%). Rootman thinks that there are three possible reasons for malignant mixed tumor: 1) the sudden growth of lacrimal gland mass for a long time; ② There were pain, bone erosion and rapid growth of tumor; ③ The pleomorphic adenoma of lacrimal gland which had been excised in the past recurred suddenly. There are different opinions on whether malignant mixed tumor is primary or secondary.

Some scholars believe that malignant mixed tumors begin to be benign and then turn into malignant, but there is no reliable basis. Henderson thinks that there are three types of primary malignant mixed tumor: 1. The history is short, and the tumor is malignant at the first resection; ② At first, the benign mixed tumor was not completely removed, but it became malignant when it recurred for the first and second time a few years later; ③ The patient has progressive exophthalmos, eye displacement, no pain for several years, recent upper eyelid swelling, pain. In the first operation of this type, there are often double pathological changes of malignant and benign mixed tumor.
