Abstract :Although lacrimal sac tumors are rarely seen, they have a high potential for local invasion, local recurrence, and distant metastasis. Given their rarity, decision making for the treatment of these tumors is based on very few case reports. Majority of these tumors are of epithelial origin. Most prominent symptoms are epiphora and mass in the medial canthus region. For this reason, it may be confused with dacryocystitis. Thorough ophthalmic examination and imaging are very important for diagnosis. Primary treatment of the disease is surgery, radiotherapy and/or chemotherapy may be used as adjuvant therapy. In our study, we compared Volumetric Modulated Arc Therapy VMAT and Intensity Modulated Radiation Therapy IMRT plans with the aim of comparing the homogeneous dose distribution and dose gradient using the Simultaneous Integrated Boost SIB technique and also assessing the dose of certain critical organs
