Incidental diagnosis of a rare endobronchial schwannoma in a 7-year-old girl: A case report. Radiol Case Rep 2022; 17:4043-4045. [PMID: 36046717 PMCID: PMC9421091 DOI: 10.1016/j.radcr.2022.07.115] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 07/27/2022] [Accepted: 07/31/2022] [Indexed: 11/24/2022] Open
Abstract
Schwannomas are nerve sheath tumors that arise from Schwann cells and are mainly benign. The likelihood of endobronchial schwannoma amongst all intrapulmonary tumors is up to 0.2% and mainly presents late. This study described a pediatric endobronchial schwannomas case discovered incidentally during rigid bronchoscopy. This case is uncommon, and its report can help physicians diagnose the same cases. The case was a 7-year-old girl presenting with fever and cough who had no history of pulmonary disease or relevant family history. Physical examination, chest radiography, CT scan, and bronchoscopy were performed on the patient. A biopsy was taken from the observed mass obstructing the bronchus during bronchoscopy. The mass was resected. Pathology revealed low-grade spindle cell neoplasm and confirmed schwannoma in immunohistochemistry. Endobronchial schwannomas can happen in children presenting with simple symptoms. For benign lesions, the prognosis is generally good. Due to the slow growth of these tumors and the potential for recurrence after resection, long-term follow-up may be needed.

Abstract
Neurogenic tumors of the tracheobronchial tree are extremely rare, and these include neurofibroma and schwannoma. The rare schwannoma most frequently is reported in adults. We will report an endobronchial schwannoma in an 11-year-old boy.

Abstract
Bronchial fibroepithelial polyps represent a rare type of tumour that displays endobronchial growth. The findings of these lesions on auto‐fluorescence imaging (AFI) bronchoscopy have not been reported, despite the usefulness of AFI in detecting early lung cancer. We report the case of a patient with a bronchial fibroepithelial polyp that displayed positivity (magenta colour) on AFI. The patient was a 65‐year‐old man, in whom an endobronchial polypoid lesion of 10 mm diameter had been detected in the right basal bronchus by chest computed tomography (CT). On bronchoscopic examination, we found a whitish, smooth polypoid lesion. The lesion appeared magenta on AFI. On CT, however, the lesion had been almost stable for 4 years and 4 months. Bronchial fibroepithelial polyps may show AFI positivity, even when the lesion displays benign behaviour. The diagnosis of the lesion should not be confused by AFI positivity, and unnecessary surgical intervention should be avoided.

Abstract
Traumatic neuromas are uncommon and benign lesions arising from a peripheral nerve injury during surgery. Here we describe a case with histopathologic features of both a traumatic neuroma and neurofibroma in a patient without integumentary physical exam findings nor prior surgical history. A 54 year old male was admitted for surgical debridement of a foot ulcer. During pre-operative evaluation and review of imaging multiple CT scans revealed a stable, 4 mm endobronchial lesion in the left lower lobe. Given history of nicotine abuse, bronchoscopy was performed. Bronchoscopy showed a pearly, polypoid lesion. Histopathological results showed strong positivity for S-100 protein and spindle cell proliferation. Repeat CT chest showed no new lesions in the bronchial tree. The rarity of this case is noted not only by the limited number of bronchial neurogenic tumors, but the combined features in this case of a traumatic neuroma and neurofibroma which has not been described.
