Squamous cell carcinoma (SCC) of the external auditory canal (EAC) is an extremely rare malignant tumor with a prevalance between 1 and 6 cases per 1 million population. The incidence is higher in patients presenting with otological diseases (1 in 5,000 to 15,000). Certain associating factors have been described in the literature. This malignancy frequently presents with symptoms similar to a case of otitis externa or a chronic suppurative otitis media. In this paper, we present a patient who had bilateral SCC of EAC caused by radiotherapy for nasopharyngeal carcinoma. To our knowledge, our case is the fifth bilateral SCC of the EAC and the first bilateral radiotherapy related SCC of the EAC reported in the literature so far.

Testicular carcinoma metastatic to the neck is rare. Even more rare is a finding of choriocarcinoma as a neck mass without any sign of a primary testicular tumor, as only a few cases have been reported in the literature. We describe a new case that occurred in a 29-year-old man who presented with a neck mass. Fine-needle aspiration biopsy identified the tumor as a malignant epithelial neoplasm. Radiologic findings indicated the presence of a systemic metastasis of a tumor to the chest and abdomen, as well as the neck. Findings on an incisional biopsy of the neck mass were consistent with a choriocarcinoma. The testicles were normal on palpation and ultrasonography. The patient was diagnosed with metastatic choriocarcinoma with an unknown primary, and he was started on chemotherapy. On the second day of treatment, which was 25 days after his referral to our clinic, he died of respiratory insufficiency.
