Maxillary sinus is frequently presented as a single space within each maxilla. It drains directly into the nose through the middle meatus. We are reporting the second rare case of a mucocele in a separate compartment of maxillary sinus in a 26-year-old patient without a history of facial trauma. The non-contrast computed tomography of paranasal sinuses showed an expansile right infraorbital cystic lesion developed in an upper lateral position of the maxillary sinus. An excision biopsy was performed, which showed histopathological findings of a maxillary sinus mucocele.
Oral squamous cell carcinoma is a potential long-term complication after hematopoietic stem cell transplantation. This may be related to mechanisms including radiation and chemotherapy regimens, chronic graft-versus-host disease, inflammation, and prolonged immunosuppression. The current case describes the development of multiple oral white thick keratotic lesions in the floor of the mouth and the tongue 6 years after hematopoietic stem cell transplantation complicated with chronic graft-versus-host disease. A biopsy performed with histopathological analysis revealed a well-differentiated squamous cell carcinoma. The patient was treated by subtotal glossectomy, bilateral neck dissection, and flap reconstruction. This report highlights the significance of the routine oral examination of long-term surveillance post hematopoietic stem cell transplantation to ensure early detection of these tumors at potentially treatable stage.
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.
