INTRODUCTION The ectopic ciliated cyst is a rare non-odontogenic cyst which occurs as a delayed complication after maxillary sinus radical surgery; this lesion emerges due to the destruction of the sinus mucosa during the surgery and entrapment of the respiratory epithelium in the region. This lesion has been observed in very rare cases following genioplasty and bimaxillary orthognathic surgery...

Sir, Median raphe cysts of the penis are uncommon benign lesions that affect young men. The cysts are lined with pseudostratified columnar or stratified squamous cell epithelium, mimicking the epithelial lining of the male urethra. Immunohistochemical study also indicates a histogenetic relationship with the urothelium. To our knowledge, there have been only 2 reports of ciliated epithelium in ...

Surgical ciliated cyst of the maxilla is a rare complication following surgical procedures or trauma involving the maxillary sinus. It can occur at any time after any procedures or trauma involving the maxillary sinus even though many years have lapsed. Clinically it may mimic other cysts of the maxillary sinus therefore a thorough history taking is necessary for diagnosis. Treatment is usually...

Cutaneous ciliated cyst are relatively rare benign lesions, found in the dermis or subcutis of lower extremities young females their second and third decades. The cysts typically lined by cuboidal to columnar epithelium, showing pseudostratified areas focal squamous metaplasia is occasionally present. Immunohistochemical studies have demonstrated that can be PR ER positive, similar epithelia fa...

Two large cysts recovered from the abdominal cavity of a domestic chicken superficially resembled hydatid cysts of Echinococcus spp. No protoscolices were present. Microscopic examination of the internal lining of one of the cysts revealed a single cuboidal to columnar, ciliated epithelium, leading to a diagnosis of oviduct cysts. Earlier records of hydatids of fowl are reviewed.

Foregut, hindgut, and tailgut cysts are uncommon developmental anomalies. Clinical and radiological diagnosis can present many challenges, especially in adult patients or when the lesions are in unique locations. Thus, diagnosis has traditionally been provided upon surgical resection. We describe the diagnoses of a gastric foregut cyst and a retrorectal tailgut cyst by endosonographically guide...

Mesenteric cysts are heterogeneous groups of lesions. Most of them are developmental cysts of lymphatic and enteric origin or cystic neoplasm such as mesothelioma or cystic teratoma. Urogenital cysts are a subcategory of developmental cysts of the mesentery. They are thought to arise from vestigial remnants of urogenital apparatus. These cysts may show evidence of mesonephric or metanephric dif...
