kimura's disease (kd) is a rare idiopathic condition of unknown etiology. the disease is characterized by swelling and lesions in the head and neck region, with involvement of the subcutaneous soft tissue, major salivary glands and lymph nodes. patients almost always have eosinophilia and elevated serum immunoglobulin e levels. the diagnosis is established by biopsy. kd is usually self limiting...

Fig, 1,-25-year-old man with parapharyngeal angiofibroma. A, Unenhanced axial CT scan shows a mass (arrows) in parapharyngeal space, with anterior displacement and splaying of pterygoid plates. B, Enhanced coronal CT scan shows an enhancing left-sided parapharyngeal mass (arrows) displacing pharynx toward right. C, Angiogram of left common carotid artery shows a hypervascular mass (arrows) supp...

This report presents a 55-year-old woman who underwent 2 Teflon injections in 1971 for a patulous eustachian tube. The patient returned in 2006 with a bloody left otorrhea. A positron-emission tomography-CT scan demonstrated a 2-cm hypermetabolic parapharyngeal mass, initially interpreted as a skull base tumor. Repeat neck CT confirmed a 2-cm hyperattenuated left parapharyngeal granulomatous ma...

Background: Mucoepidermoid carcinoma ex-pleomorphic adenoma (MECxPA) is an extremely rare salivary gland malignancy. With only nine prior reported cases, this entity represents a challenging histopathological diagnosis. Methods: We present a case of a 71-year-old male with an enlarging left neck mass over several months. CT showed both a parapharyngeal space mass and a separate level II neck ma...

Introduction: Extraosseous Ewing’s sarcoma (EES) of the head and neck region is a rare occurrence, and Ewing’s sarcoma of the parapharyngeal space is even rarer. To the best of our knowledge, only three cases of EES of the parapharyngeal space have been reported in the literature.   Case Report: We report a rare case of EES of the parapharyngeal space in an 8-year-old girl. She presented with c...

Parapharyngeal pleomorphic adenoma (PA) is a benign tumor of the salivary glands. We report a rare case of giant benign parapharyngeal PA with intracranial extension in a 69-year-old male who presented with aural fullness. Magnetic resonance imaging (MRI) showed a large, lobulated, well-defined mass in parapharyngeal space with erosion of the base of the middle cranial fossa and extension to th...

A 44-years-old male presented with right infraauricular swelling. It had been four months since he was aware of the mass. He had not felt any pain or tenderness. Computed tomograpy demonstrated a homogenous, regular surfaced mass located in the prestyloid and poststyloid parapharyngeal space. Its density was concordant with lipomatous tissue, so it was considered to be an infiltrating paraphary...

BACKGROUND The metastasis of papillary thyroid carcinoma to the parapharyngeal space is rare and discussed in the English literature before. Encountering a parapharyngeal mass with cystic appearance on imaging, one should rule out thyroid malignancy as differential diagnosis. CASE PRESENTATION The case presented here is a 22-year-old woman who was referred to our clinic with complaints of pai...

BACKGROUND Preliminary case series have reported clinical feasibility and safety of a transoral minimally invasive technique to approach parapharyngeal space masses. With the assistance of the surgical robotic system, tumors within the parapharyngeal space can now be excised safely without neck incisions. A detailed technical description is included. METHODS After developing compressive sympt...
