Successful Treatment of a Bilateral Lower Palpebral MALT Lymphoma with Rapid Arc: Description of a New Technique Issam Lalya Laila Baddouh Keltoum Dahmani Noha Zaghba Khalid Andaloussi Mohamed Elmarjany Khalid Hadadi Hassan SifatHamid Mansouri<p>Primary&nbsp; MALT&nbsp; lymphoma&nbsp; of&nbsp; the&nbsp; eyelids&nbsp; is&nbsp; a&nbsp; rare&nbsp; disease;chronic infection by Chlamydophila psittaci has been identified as a possible causative agent, but other pathogens may be implicated such Hepatitis C virus and Helicobacter Pylori. This tumor is considered to have an indolent natural history and a favorable prognosis. Radiation therapy with moderate doses is the corner stone of treatment offering excellent local control with low complications rate. We report herein the radiation therapy treatment plan of a 65-year-old man presented to&nbsp; our&nbsp; department&nbsp; with&nbsp; a&nbsp; primary&nbsp; bilateral&nbsp; lower&nbsp; palpebral&nbsp; MALT lymphoma.&nbsp; CT&nbsp; scan&nbsp; of&nbsp; 2.5-mm&nbsp; slice&nbsp; thickness&nbsp; in&nbsp; supine&nbsp; position was&nbsp; realized.&nbsp; A&nbsp; bolus&nbsp; of&nbsp; 1cm&nbsp; adapted&nbsp; to&nbsp; closed&nbsp; eyes&nbsp; (glasses-like) were&nbsp; placed&nbsp; and&nbsp; fixed&nbsp; to&nbsp; palpebral&nbsp; surface&nbsp; (Figures&nbsp; 1,2),&nbsp; before immobilization&nbsp; with&nbsp; standard&nbsp; thermoplastic&nbsp; mask&nbsp; (Figure&nbsp; 3).&nbsp; The clinical target volume included the tumor, lachrymal glands and the entire orbit. The planning target volume was obtained by automatic margin&nbsp; of&nbsp; 5&nbsp; mm&nbsp; around&nbsp; the&nbsp; clinical&nbsp; target&nbsp; volume.&nbsp; Optic&nbsp; nerves,eyeballs&nbsp; and&nbsp; lens&nbsp; were ontoured&nbsp; as&nbsp; organs&nbsp; at&nbsp; risk. </p> International Journal of Radiology and Radiation Oncology - Peertechz Publications 2016-07-05 Clinical Image https://doi.org/10.17352/ijrro.000015 en Copyright © Issam Lalya et al.
