Most of the primary malignant lymphomas of the salivary
glands originate from the parotid gland. We presented two
patients who were admitted with a painless mass in the
parotid region and diagnosed to have lymphoma. Physical
examination of a 66-year-old male patient showed a relatively
mobile, painless, and firm mass at the inferior aspect
of the right parotid gland. Ultrasonography, computed
tomography (CT), and magnetic resonance imaging (MRI)
were performed and a needle biopsy was obtained from the
solid lesion extending from the right parotid superficial lobe
to the medial deep lobe. Pathological examination revealed
large B-cell lymphoma. The patient was treated according to
the CHOP chemotherapy protocol. The second patient had
undergone surgery for orbital lymphoma and received
CHOP chemotherapy. On physical examination, there was a
painless mass in the parotid cauda on the left and a subcutaneous
lymph node, 0.5x1 cm in size, inferior to the parotid
cauda. Computed tomography and MRI showed an irregularly
contoured solid lesion, 2x1 cm in size, in the posteroinferior
aspect of the superficial lobe. Lymph node biopsy
yielded a diagnosis of small cell malignant lymphoma. The
patient was referred to the medical oncology department for
staging, further investigation, and planning of the treatment.
