Mucosa-associated lymphoid tissue (MALT) is a no encapsulated cluster of lymphocytes that is thought to have important role in mucosal immunity. Maltoma is an extranodal lymphoma either of B- or T-cell origin that may most common involve stomach, followed by other gastrointestinal organs, respiratory tract, skin and others containing lymphoid tissue parts. Maltoma in salivary gland is a rare entity because it is not a part of salivary gland tissue, but chronic inflammatory processes can cause lymphocyte accumulation in gland and these cells can be cause of Maltomas. Tumors located in parotid gland are reported to be malignant in 26-32% of cases. Physical examination does not effective to rule out malignancy in all cases. Preoperative studies including imaging modalities such as ultrasonography (US) and magnetic resonance imaging (MRI), and histopathological studies (fine needle aspiration cytology (FNAC)) are used to have accurate preoperative diagnosis. In this case, we report a rare tumor of parotid gland in a patient with breast cancer history that is confusing clinical situation and the insufficiency of preoperative and peroperative diagnostic studies to determine the pathology in parotid gland. Despite improvement of diagnostic studies personal experience and evaluation of clinician remains most important part of planning of treatment strategies for parotid gland neoplasm.
