Hemangiopericytomas are soft tissue tumors composed of pericapillary pericytes. These tumors are rare in the lacrimal sac. To the author's knowledge, only four previous cases of these tumors occurring in the lacrimal sac have been reported. A primary hemangiopericytoma of the lacrimal sac in a 34-year-old female is reported. Total excision with the surrounding tissue appears to be the treatment of choice for this tumor.

2.Cyst of accessory lacrimal gland.
Korean Journal of Ophthalmology 1995;9(2):117-121
When a patient is presented with a subconjunctival cyst, it is not only hard to reveal its true nature clinically but also easy to rupture during excision. We experienced cases with cysts of the accessory lacrimal gland in two patients with subconjunctival cysts. They had lid swelling at initial presentation and underwent surgical excision of subconjunctival cysts located in superior portion of the upper tarsal plate. The lining of these cysts composed of ductal epithelia. Biochemical analyses for serum and cystic fluid were performed in one case, in which was found high Ig A titer in the cystic fluid. These cysts seemed to originate from the duct of Wolfring's accessory lacrimal gland, considering their anatomic locations and pathologic findings. Complete removal of the cyst is important, because recurrences have been reported in cases of incomplete removal or simple aspiration.
