A giant pyogenic granuloma gravidarum in the nasal cavity: A case report.

Pyogenic granuloma (PG) is a benign fibrovascular proliferative lesion on the skin and mucous membranes, but its pathogenesis remains unclear. PG usually occurs on the head and neck region, fingers and toes. The oral gingiva is the most common location for pregnant patients, while it is rarely found in the nasal cavity. This case is notable not only for its uncommon site and size but also for its gradual growth after delivery. Endoscopic surgery can achieve the desired cosmetic effect and a satisfactory airway. A rapidly growing hemorrhagic lesion in the nasal cavity should be considered as a differential diagnosis.

Endoscopic Management of Recurrent Maxillary Sinus Ameloblastoma in a Child With Autism Spectrum Disorder: A Case Report.

Ameloblastomas are slow-growing, aggressive odontogenic epithelial tumors that originate from the jawbone. One of the most easily relapsing maxillofacial tumors, ameloblastomas mainly occur in the mandibular molar area and ascending branch, although they can occasionally occur in the nasal cavity and paranasal sinuses. A 14-year-old child with autism spectrum disorder underwent sinus computed tomography (CT) under anesthesia. A swollen tumor had grown in the left maxillary sinus, and the bone of the maxillary sinus was damaged. Nine months after the first operation, recurrence was observed in the left maxillary sinus. The pathological diagnosis was ameloblastoma. Due to the child's inability to communicate and cooperate with the treatment normally, he underwent endoscopic surgery again combined with low-temperature plasma treatment. No tumor recurrence was found on reexamination 6 months after surgery.

[Clinical analysis of sphenoid disease manifesting orbital apex syndrome].

OBJECTIVE: To investigate the relationship of sphenoid disease and orbital apex syndrome and to improve the diagnosis of sphenoid disease. METHODS: Twelve patients with sphenoid disease manifesting orbital apex syndrome from 2000 to 2004 were retrospectively analyzed, especially the processes of both diagnosis and treatment. The factors which may lead to misdiagnosis were discussed. RESULTS: All the twelve patients failed to be correctly diagnosed at the ophthalmology department. Having been undergone CT or MRI, seven cases of sphenoiditis, three cases of polyps of sphenoidal sinus and two cases of sphenethmoid mucocele were confirmed respectively. All of the patients underwent endoscopic sphenoid surgery. The symptoms of the patients were improved or disappeared after the operations. CONCLUSIONS: The sphenoid disease with orbital apex syndrome was easily misdiagnosed. The possible causes of misdiagnosis were: low incidence of the disease, nonspecific eye symptoms, and unawareness of the doctor, especially ophthalmologist. CT or MRI are the gold standards of diagnosis of sphenoid disease. Endoscopic sinus surgery is effective and safe technique for the treatment of the disease.
