Actinomycosis is a bacterial infection caused by actinomyces. Although almost 50% of cases are related to the head and neck region, those in the nose and paranasal sinuses (PNS) are rare. Actinomycosis of the PNS is presumed to be typically caused by dental caries, dental manipulation, and maxillofacial trauma, which facilitate the penetration of oral pathogens into the sinus, and should thus be treated by the combination of surgical removal and potent antibiotics for at least two months. The current use of these antibiotics might be redundant, considering the nature of actinomycosis of the PNS, which does not invade the mucosal surface. We herein report a 67-year-old female treated with endoscopic sinus surgery (ESS) and diagnosed with actinomycosis of the PNS by pathological findings. She had no history of dental impairment or treatment. She was given routine perioperative prophylactic antibiotics (cefazolin) during the surgery, followed by low-dose clarithromycin. The mucosa of the PNS normalized without any discharge by three months after the operation. The patient is a valuable example that should prompt reconsideration of the commonly accepted pathogenesis and treatment of actinomycosis of the PNS.
Lingual osseous choristoma is a rare benign tumor consisting of normal matured bone tissue. It was first reported in 1913, and less than 100 cases of lingual osseous choristomas, mainly in their twenties and thirties, have been reported in the English literature until now. Here, we report an additional case of lingual osseous choristoma, in an elderly patient, that was incidentally removed by coughing and cured without additional interventions. An 89-year-old male patient was referred to our department for an evaluation of chronic cough. When we examined his oral cavity and pharynx, he expectorated a 10 -mm mass which was histologically diagnosed as an osseous choristoma. We confirmed the well-defined, rounded, high-density mass with a tiny pedicle on the base of the tongue in previous cervical spine CT images. No signs of recurrence were found during the 15-month follow-up examination. Our case serves as a reminder of this rare entity in the diagnosis of tongue masses of the elderly.
Respiratory epithelial adenomatoid hamartomas (REAHs) are rare tumors occurring in the nasal cavity and sinuses, and their etiology is unknown. REAH is a relatively recently established lesion and is often misdiagnosed as nasal polyposis or other tumors. Preoperative endovascular embolization for sinonasal tumors is now widely accepted as an effective method to reduce blood loss, soften the tumor, and facilitate surgical procedures. However, to the best of our knowledge, there are no reports of the requirement for preoperative embolization in the management of REAH. Here, we present a 70-year-old man with an easily bleeding REAH of the olfactory cleft, vascularized by branches of the bilateral internal and external carotid arteries. We removed the tumor endoscopically after preoperative embolization of the bilateral sphenopalatine arteries. Histological investigation revealed an intratumoral hemorrhage accompanying the REAH, with no evidence of a residual or recurrent tumor during the last follow-up at 3 months. In conclusion, accurate preoperative diagnosis and proper preoperative interventions such as embolization are needed for safe and adequate treatment of REAHs that have an abundant blood flow.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
