Totally cervical thymoma is extremely rare and usually arises from ectopic thymic
tissue. We report a case of a B1 thymoma localized in the neck, misdiagnosed for a
decade as a thyroid nodule. Fine needle aspiration biopsy led to a preoperative suspicion
of the correct diagnosis. The tumor was resected intact through a cervical collar
incision, along with the upper thymic horn from which it originated. A pathogenetic
hypothesis was formulated.
