Persistent carcinoma of the trachea is an uncommon thoracic malignancy with limited treatment options. To our knowledge pembrolizumab, an immunotherapy targeting programmed death 1, has not been previously reported as an effective therapy for tracheal carcinoma. Here we describe a case of recurrent tracheal squamous cell carcinoma refractory to photodynamic therapy, radiotherapy, and cryotherapy. Programmed death ligand 1 was positive in 90% to 95% of tumor cells. A complete tumor response was observed after three months of treatment with pembrolizumab. No adverse events were reported at the 11-month follow-up. Based on our experience, pembrolizumab represents another viable treatment option for tracheal carcinoma.

Undifferentiated pleomorphic sarcoma in the maxillary sinus: a case report.

Department of Oral and Maxillofacial Pathology, School of Dentistry, Shahid Sadoughi University of Medical Sciences, Yazd, Iran.
Background: Undifferentiated pleomorphic sarcoma, previously called malignant fibrous histiocytoma, is a type of malignant mesenchymal tumor (sarcoma) of soft tissue and sometimes bone. It is uncommon in the oral cavity and very sporadic in the maxillary sinus. Microscopic diagnosis of this malignancy in the maxillary sinus can be very challenging, because there is a range of features that may overlap with other benign and malignant tumors.
