A Rare Malignant Transformation of Benign Lacrimal Tumor
Lacrimal gland tumors are common in middle age group individuals. Proptosis is one of their
common presentations. Sometimes the tumors may undergo malignant changes which if neglected
can be life threatening. Here we present a case of 49 years male with gradual painless protrusion and
diminution of vision in his right eye for eight years and more since last 2 months, with restriction
of ocular motility in right lateral gaze. Expecting a benign mass, superolateral orbitotomy with
excisional biopsy was done which astonishingly revealed carcinoma ex pleomorphic adenoma
with components of adenocarcinoma and squamous cell carcinoma without any lymphovascular
invasion. Proptosis and vision of the patient in right eye improved post excisional biopsy without
any residual mass in respective follow ups.
Keywords: adenocarcinoma; lacrimal gland; malignant transformation; proptosis.
