RESUMO
Mucosa associated lymphoid tissue lymphoma is a rare disease particularly when occurring in the lungs. In 1983, Issacson and Wright first described it as a distinct clinicopathological entity. A 39-year-old woman was suffering from mucosa associated lymphoid tissue lymphoma of the lung and was treated with moderate dose radiotherapy only. Six months after treatment the woman is symptom free and without any evidence of relapse. The disease undergoes a very indolent course and local form of treatment like surgery or radiotherapy is effective though radiotherapy is probably associated with higher local control rate and event free survival particularly in early stages. But for diagnostic purpose thoracotomy is generally required in pulmonary variety. Due to rarity of cases it is almost impossible to compare surgery with radiotherapy in mucosa associated lymphoid tissue lymphoma disorder in a prospective manner. Radiotherapy is the preferred mode of treatment either alone or in combination with surgery.
