RESUMEN
Synovial sarcomas are high-grade soft tissue sarcomas of primitive mesenchymal origin which are defined by a pathognomonic t(X;18)(p11,q11) translocation, and which occur in pediatric and adult populations. Herein we report a case of a 33-year-old female with a history of nasopharyngeal carcinoma status post radiotherapy, presenting with a poorly differentiated synovial sarcoma of the nasal cavity arising in the radiation field. While the development of radiation-associated sarcoma is a known complication of radiotherapy, to date only 10 cases of synovial sarcoma have been reported to occur in previously irradiated tissues. Moreover, only 1 case of poorly differentiated synovial sarcoma involving the nasopharynx has been described.

Nodular hyperplasia of the Bartholin's gland is an underreported and extremely rare entity that presents as a solid lesion potentially raising concern for malignancy clinically, most solid lesions at this location are carcinomas. They may also be mistaken for a Bartholin cyst clinically. Nodular hyperplasia is rarer than carcinoma of the Bartholin gland, and hence pathologists may not be familiar with this entity, making it a pitfall in pathologic as well as a clinical diagnosis. Here we report a case originally considered a Bartholin cyst, but raising intraoperative concern due to solid elements. Histological examination of the lesion revealed nodular hyperplasia of Bartholin's gland. Recognition of this entity is important, as it is something that may be encountered by the pathologist.
