A 73-year-old woman having a throat lump sensation and dysphagia for the past several months presented at our otorhinolaryngology outpatient clinic. A physical examination disclosed a protruding subepithelial mass over the right tonsil fossa. The mass was not tender and had no mucosal lesions or signs of active infection. Therefore, we arranged face and neck computed tomography scans, which reported a solitary osseous lesion over the anterior-right aspect of the C1-2 joint. Considering the rarity and unfamiliar anatomy of this disease, we built a 3D-printed model to assist with the surgical rehearsal of the procedure as well as with a preoperation discussion with the patient and her family. We arranged a combined Otolaryngology-Neurosurgery department approach after discussion with the neurosurgeon and successfully removed the lesion without sacrificing the overlying longus capitis muscle. The pathology examination revealed no evidence of malignancy. The final diagnosis was cervical spine solitary osteochondroma. The patient had a complete recovery of both oral cavity and normal swallowing function. No tumor recurred during the 3-year follow-up. On the basis of this case, in-house 3D-printing technology can offer a rapid, reliable model for an interdisciplinary team to use to enhance personalized presurgical planning, thus providing better patient engagement during hospitalization., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and publication of this article.

Schwannomas are rare slow-growing benign tumors arising from Schwann cells lining the nerve sheaths. Head and neck schwannomas account for about one-third of all cases, and only 4% of them arise from the sinonasal tract. Its diagnosis is based on histology and immunohistochemistry. Complete surgical excision is the most recommended treatment option, and endoscopic surgery has been widely performed in recent years. In this study, we presented a case of a 55-year-old female with schwannoma arising from the lateral wall of the nasal cavity, causing epistaxis and rhinorrhea. The patient underwent endoscopic excision with prompt resolution of symptoms. The reported cases of nasal cavity schwannoma were reviewed and summarized for educational purposes., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Warthin tumor with ulceration of the surrounding skin is extremely rare, making it difficult to differentiate from parotid cancer in the clinical setting. We report a 65-year-old man with a Warthin tumor in the right parotid gland that had ulceration of the overlying skin. The patient presented with right upper neck mass 2 years ago. Ultrasound and fine needle aspiration were done, and Warthin tumor was suspected. One year later, the mass was enlarged with ulceration of the skin. Superficial parotidectomy with fusiform excision of the skin was performed, and histopathological diagnosis revealed a Warthin tumor with inflammatory change. We proposed that this unique manifestation may have been induced by fine needle aspiration, enlargement of the tumor, and ischemic changes secondary to pulmonary arteriovenous malformations.
