“…There are 42 cases of PNS cholesteatoma in the English medical literature: 17 in the frontal sinus, 15 in the MS, 5 in the ethmoid sinus, 3 in the sphenoid sinus, and 2 in the concha bullosa. 1 Four basic theories have been proposed to explain the development of cholesteatoma: congenital epithelial rests, squamous metaplasia, immigration, and implantation theories; however, none can describe the formation of PNS cholesteatoma. Previous reports have often associated PNS cholesteatomas with a history of surgery, trauma, or unerupted teeth, but our case was unique in that there were no such histories.…”

The preoperative diagnosis of a paranasal epidermoid cysts (EC) is challenging and is frequently mistaken. We present the case of a patient who developed a swelling on the left side of the face. The clinical examination showed a fixed and poorly defined swelling in the left maxillary region, with a slightly painful bulge in the upper vestibular peri-gingival area. A computed tomography (CT) scan showed a well-encapsulated expansive hypodensity that filled the left maxillary sinus. Magnetic resonance imaging (MRI) revealed a mass hypo-intense on T1-weighted images, high intense on T2-weighted images, hyperintense on diffusion-weighted images, and had a low apparent diffusion coefficient with no contrast uptake observed after the injection of Gadolinium. Surgical excision under general anesthesia was considered. A combined approach using an endoscopic sinus and Caldwell-Luc approach was performed and the histopathological examination confirmed the diagnosis of an EC. In conclusion, the preoperative imaging, including CT scans and MRI, aids in diagnosing ECs and differentiating them from other sinus tumors. Postoperative follow-up involving endoscopic surveillance and CT scans is crucial to monitor for potential recurrence.

Epidermoid cysts are rare benign lesions that can derive from abnormally situated ectodermal tissue during embryological development or from implanted epithelium after trauma or surgery. In the oral and maxillofacial regions, epidermoid cysts usually develop in the floor of the mouth and rarely in other sites. We describe a rare case of an epidermoid cyst arising in the right maxillary sinus. A 29-year-old man with a known diagnosis of Marfan syndrome presented with progressive swelling and tenderness in the right buccal region, mimicking facial cellulitis, and refractory to medical treatment. Computed tomography scan showed a cystic lesion extending widely into the right maxillary sinus. The cyst was successfully removed with a medial maxillectomy through inferior antrostomy approach under general anesthesia. Histological examination confirmed the diagnosis of an epidermoid cyst, showing a cystic wall lined with a thin layer of keratinizing squamous epithelium and fibroma connective tissue infiltrated with inflammatory cells, with no skin appendages. There has been no evidence of recurrence during the 4 year follow-up. We also conduct a review of the English literature for the reported cases of maxillary epidermoid cyst.
