Abstract

Desmoplastic fibroblastomas (DF) are rare, benign, soft tissue tumors affecting mainly the subcutaneous tissue or skeletal muscle at a variety of anatomical sites, but rarely occurred in parapharyngeal space. Herein, we describe an unusual case of 61-year-old man, who presented with a parapharyngeal space mass for 1-month. The clinical examination revealed the right lateral pharyngeal wall bulging into pharynx, and mucosa was smooth. Computed tomography showed a heterogeneous tumor with a well-defined margin, which involved the soft palate and extended to the pyriform, measuring approximately 3.5 cm × 2.5 cm × 1.0 cm, which was resected by transoral approach with tracheotomy. Histopathology and immunohistochemistry staining revealed a DF. To our knowledge, this is the first reported case of DF arising in parapharyngeal space.
