The advent of computer-aided design and computer-aided manufacturing (CAD/CAM), along with direct metal laser sintering (DMLS), has enabled the fabrication of high-precision frameworks and extracoronal precision attachments with improved biomechanical and esthetic outcomes. This case report presents the digital rehabilitation of a partially edentulous maxillary arch classified as Kennedy Class II Modification 2, utilizing a CAD/CAM-designed and DMLS-fabricated cast partial denture. The digital workflow encompassed intraoral scanning, virtual framework design, and additive manufacturing of the prosthesis with integrated precision attachments.

Endoscopic examination revealed a polypoid lesion arising from the right inferior turbinate-an exceptionally uncommon site. Computed tomography demonstrated a well-circumscribed mass confined to the inferior turbinate without bone erosion, while a positron emission tomography scan with a computed tomography revealed no fluorodeoxyglucose uptake. Histopathological evaluation confirmed the diagnosis of sinonasal oncocytic papilloma, characterized by oncocytic epithelium with eosinophilic cytoplasm and intraepithelial microcysts. The patient underwent endoscopic partial turbinectomy with complete excision of the lesion. Postoperative recovery was uneventful, and follow-up nasal endoscopy at one year showed complete mucosal healing without evidence of recurrence or polypoid degeneration. This case highlights an unusual localization of sinonasal oncocytic papilloma and underscores the diagnostic challenges associated with its differentiation from inflammatory and neoplastic lesions. It further emphasizes the importance of correlating histopathologic findings with imaging modalities, including a positron emission tomography scan with a computed tomography, in achieving an accurate diagnosis and optimal management of this rare entity.</p>","PeriodicalId":12415,"journal":{"name":"Folia medica","volume":"68 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148864420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The condition is classified into subtypes based on the morphology of the cysts and the extent of pulmonary parenchymal involvement. Clinical symptoms are nonspecific. The aim of this study is to present a case of CCAM type II diagnosed de novo in an adult. A 43-year-old patient was admitted to the clinic due to an abnormal finding on a chest X-ray. A large conglomerate of lesions was located in the inferior lobe of the left lung, and the patient had a history of recurrent pneumonia. After initial diagnostic tests and confirmation of the lesion's location on chest computed tomography, the patient was qualified for surgical intervention. The lesion was removed via video-assisted thoracoscopic surgery, and histopathological examination confirmed the diagnosis of CCAM type II. At the six-month follow-up visit, no recurrence was detected, and treatment was completed. Although it is extremely rare, CCAM type II can also occur in adult patients.
