BACKGROUND: Warthin @entity5 presenting concomitantly with a @entity706 is vanishingly rare with only 15 reported cases in English literature. Herein, we report an unusual initial presentation of a @entity1073 involving the @entity706 of a @entity4724 . CASE PRESENTATION: A seventy-seven year old otherwise healthy gentleman with a 50-pack year smoking history presents with a slowly enlarging left cheek mass. CT scan of the neck demonstrated a left @entity5 measuring 3.4 cm in greatest dimension. He underwent a left superficial parotidectomy, with subsequent histopathologic examination revealing a @entity4724 with extensive expansion of the @entity706 . Flow cytometric, immunohistochemical, and cytogenetic studies of the stromal component of the @entity5 confirmed the presence of a @entity1073 . Clinical staging demonstrated stage IVa disease, and was considered to be at low to intermediate risk due to the slow growth of the parotid lesion. The @entity1 is undergoing close follow up with repeat PET-CT scans at six months. CONCLUSION: To the best of our knowledge, this is the first well documented collision @entity5 between @entity1073 and a @entity4724 . This case also brings to light the significance of thorough evaluation of the lymphoid component of @entity4724 .
