The management of metastatic squamous cell carcinoma can be challenging in patients with low-grade non-Hodgkin lymphoma. 18F-fluorodeoxyglucose positron emission tomography can be useful in the diagnosis of metastatic squamous cell carcinoma in patients with low-grade non-Hodgkin lymphoma.

Choanal stenosis has recently been recognized as a late complication of radiation therapy for nasopharyngeal carcinoma. The management of velopharyngeal stenosis is challenging with high risk of restenosis. We report a case of velopharyngeal stenosis post-radiotherapy and illustrated the use of mitomycin-C to prevent restenosis. Mitomycin-C application has being shown useful adjunct to surgical technique in managing nasopharyngeal stenosis for surgeons.

A total of 61 submandibular glands were treated by the transoral approach. Patients with multiple stones (p = 0.034) and stones in the proximal submandibular duct (p = 0.0028) were at greater risk of requiring submandibular gland excision, compared with patients with single stones and stones in the distal duct, respectively. There was a significant difference between the gland preservation rate during the first versus the second half of the study (p = 0.028). Larger calculi were significantly more likely to be seen in the proximal duct (p < 0.001). The mean operating time (28 minutes) and length of hospital stay for transoral removal of submandibular calculi was much less than those for other treatment techniques.

Inflammatorypseudotumor (IPTJ isa rare, locally aggressive, benign neoplasm ofunknown etiology.It isuncommon in theheadand neckregion,particularly in theparanasal sinuses. We presentan unusual case ofIPTofthemaxillary sinus and orbit in a 27-year-old woman who presented with cheek swelling, right orbital swelling, double vision, andassociatedfeverand trismus. Computed tomography identified a mass with radiologic features suggestive of a malignancy of the maxillary sinus and orbit; the mass extended into the infratemporal fossa, parapharyngeal space, anterior antral wall, andsurrounding softtissue. A diagnosis of IPT wasestablishedon the basisofhistologic and immunohistochemical analysis, which identified a proliferation of blandspindle cells and a mixed inflammatory cell infiltrate. Despite its aggressive appearance, IPT isassociated with agoodprognosis. Ourpatient was treated successfully witha combination ofsurgery, steroid therapy, and methotrexate. Chemotherapeutic agents are generally reserved for recalcitrant cases.
