Small Cell Neuroendocrine Carcinoma of the Paranasal Sinuses with Unexpected Location and Clinical Presentation and Occupational Exposure: A Case Report.

BACKGROUND Small cell carcinoma (SCC) is usually aggressive and associated with a poor prognosis. This type of cancer is rarely found in extra-pulmonary or digestive-tract locations. This report describes an unusual presentation in terms of clinical symptoms and primary location (even among head and neck presentations), and unexpected occupational exposure. CASE REPORT This case report is a novel observation of SCC in the paranasal sinuses and is to the best of our knowledge the first case associated with occupational exposure to sawdust, with almost no ear, nose, and throat (ENT) symptoms related to the primary tumor location. Our patient had no past medical history and none of the usual risk factors, apart from a smoking history of 32 pack-years. He was not taking any regular treatment. The inaugural clinical presentation was mainly digestive, with neither ENT nor neurological symptoms. Diagnostic wavering ensued and numerous paraclinical tests were performed. This is one of the very few cases of an ethmoidal location ever reported for SCC. This cancer type is unusual in neck and head locations, but has occasionally been reported in the larynx and hypopharynx. To the best of our knowledge, this is only the second report of an ethmoidal location. In addition, this patient was a carpenter, implying exposure to sawdust, which is usually associated with adenocarcinoma of the ethmoid. We illustrate here that SCC, which has been described elsewhere without sawdust exposure, is also possible. CONCLUSIONS Exposure to sawdust should suggest a possible ethmoidal cancer location, even if there are few ENT symptoms. Adenocarcinoma is the most prevalent but clearly not the only possible histological pattern.

Bone-Anchored and Closed Skin Bonebridge Implant in Adults: Hearing Performances and Quality of Life.

INTRODUCTION: Bonebridge® is a novel active bone-anchored hearing implant. The purpose of this study was to evaluate the ease of implantation, the hearing performances, and the patient-reported benefit. MATERIALS AND METHODS: This is a prospective cross-sectional study of 24 consecutive adult patients implanted for a mixed hearing loss (13 chronic otitis media (COM) and 11 other aetiologies). Twenty-one implants were placed in the retrosigmoid position and 3 in the mastoid. Audiometry, Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire, as well as 5 implant-specific questions (analogue visual scale [AVS] 0-10 score), was administered. RESULTS: Surgery lasted 73 ± 29.7 min on average. No major complication occurred. All patients were users at the last follow-up visit (median: 9-month range: 3-25). The average prosthetic gain was similar in COM and other aetiologies (43 ± 4.8 dB and 50 ± 7.2, respectively, not significant, Wilcoxon test). Bone-conduction thresholds were not deteriorated by surgery (Kruskal-Wallis test, not significant). APHAB scores improved in all categories except aversiveness (global score 45 ± 7.0% in COM and 32 ± 10.2% in others, not significant, and Wilcoxon test). Local pain (AVS: 3.23 ± 3.2, n = 16) and manipulation difficulties (3.1 ± 3.69) were low. The device was considered aesthetic (8.3 ± 2.49). Perfectible autonomy (5.0 ± 2.8) and difficulties wearing the implant during sport or at work (5.1 ± 3.47) were the weakest points. CONCLUSIONS: BoneBridge® implant provides reproducible results for the rehabilitation of mixed hearing losses and unilateral hearing loss.
