INTRODUCTION: Lacrimal sac is the closed upper end of the nasolacrimal duct and has a fibro-elastic wall lined internally by mucosa that is continuous with the conjunctiva through the lacrimal canaliculi and within the nasal mucosa through the nasolacrimal duct. Primary lacrimal sac tumors are rare compared to other orbital tumors. Mucoepidermoid carcinoma is a tumor that contains both neoplastic mucin producing and epidermoid cells. Mucoepidermoid carcinoma of the LS is very rare. Early treatment of these tumors is essential because they tend to be infiltrating tumors. Multiplanar CT imaging of the paranasal sinuses and orbit is essential for defining the extent of the tumor and for finding evidence of bony destruction of the lacrimal fossa.

PRESENTATION OF CASES: In the department of ophthalmology, G.S.L medical college, Rajahmundry, we came across a case of 60 years old male with a history of swelling and lacrimation in right eye since 1 year, provisionally diagnosed to be Lacrimal gland adenoma with suspicious malignant change.

CONCLUSION: it is first of its kind we came across after many years and review of literature reveals various sac malignancies. Methodical approach, correct pathological report and radiological diagnosis are vital to decide the treatment modalities like simple excision, radical surgery, radio therapy. From this case we acquired immense knowledge about sac tumours and various treatment modalities and disease course, made us easy to tackle in such cases of sac malignancies in future.
