Case presentation A 43-year-old Caucasian woman presented in her 32nd week of gestation with a tumor of the parotid gland. Ultrasonography of her neck showed a parotid lesion of 40 X 30 X mm. A follow-up magnetic resonance imaging scan of the neck four weeks later revealed that the tumor had grown to 70 X 60 X 60 mm reaching the parapharyngeal space with marked obstruction of the oropharynx of about 50 . After discussing the case with our multidisciplinary tumor board and the gynecologists it was decided to deliver the baby by caesarean section in the 38th week of gestation and then to perform a surgical resection of the tumor. Conclusion Indications for early surgical intervention of similar cases should be discussed on an individual patient basis in a multidisciplinary setting.

Case presentation A 43-year-old Caucasian woman presented in her 32nd week of gestation with a tumor of the parotid gland. She had noticed the swelling increasing over the past six
