A 51-Year-Old Man With Hoarseness of Voice.

CASE PRESENTATION: A 51-year-old nonsmoking man presented to his general practitioner with a primary complaint of 4 months of progressive hoarseness, and was subsequently referred to an otolaryngologist. He had no relevant medical or surgical history. He did not take any chronic medications or supplements. He was born in the Dominican Republic and moved to New York City when he was 36 years old. He worked in construction. In his spare time, he would return to his home country. The patient was a lifelong nonsmoker and reported no alcohol consumption. He denied shortness of breath, cough, sputum expectoration, fevers, chills, and night sweats.

Spontaneous Giant Laryngeal Granuloma in the Absence of Laryngeal Injury.

The etiology of laryngeal granuloma can typically be attributed to endotracheal intubation, vocal abuse, or gastroesophageal reflux disease. There is a strong male predominance, except in cases due to intubation, where incidence is higher in women. We report a case of spontaneous development of multiple granulomas in a female with no history of intubation who presented with hoarseness and massive bilateral supraglottic masses obscuring her glottis. The disparity between the massive lesions and asymptomatic reflux highlights the need for further research in the pathophysiology of laryngeal granulomas.

Evaluation of narrow band imaging in the assessment of laryngeal granuloma.

Laryngeal granulomas belong to common complications following trans-oral laser microsurgery (TLM). The aim of this study was to evaluate NBI in the differentiation between granuloma-like lesions and local tumor recurrence. 154 consecutive patients after TLM due to early laryngeal cancer were enrolled. In the group, a monthly follow-up including NBI endoscopy was performed. Moderate and severe dysplasia, carcinoma in situ and invasive cancer were defined as positive histology, laryngeal granuloma and other benign laryngeal lesions as negative histology and premalignant lesions as suspicious histology. In 47/154 (31%) cases, granuloma-like lesion (GLL) was found. Patients with GLL were divided into two groups based on the NBI classification. In all patients, the microvascular pattern in NBI was compared with the final histology. In group A, with suspicious, perpendicular vessels, 13/13 (100%) samples were positive. In group B, with normal vascular pattern 3/34 (9%) samples were positive and 31/34 (91%) samples were negative. There was a significant correlation between the positive NBI vascular pattern and the final histology (p = 0.00001). Sensitivity, specificity, accuracy of NBI were as follows: 81%, 100%, 94%, respectively.Based on our results, NBI can reliably differentiate between postoperative laryngeal granuloma and local tumor recurrence. In such a manner, this method is very helpful in the follow-up of tumor patients.

Massive Idiopathic Oropharyngeal and Laryngeal Granulomatosis on FDG PET/CT.

Idiopathic granulomatosis is a rare entity and has varied manifestations and imaging findings. A 44-year-old woman with sore throat and worsening dyspnea had multiple oropharyngeal and supraglottic masses on laryngoscopic examination. FDG PET/CT demonstrated diffuse tumor-like mucosal/submucosal lesions with intense uptake involving the oropharynx, supraglottis, and hypopharynx. Surgical biopsy showed chronically inflamed granulation tissue without malignancy, necrosis, or vasculitis. All stains were negative for any organisms. The image highlights the necessity of including granulomatosis as a differential from malignancy in interpretation of FDG PET/CT showing diffuse mucosal/submucosal oropharyngeal and/or laryngeal lesions but without established diagnosis.

Spatiotemporal analysis of high-speed videolaryngoscopic imaging of organic pathologies in males.

PURPOSE: The aim of this study was to identify parameters that would differentiate healthy from pathological organic-based vocal fold vibrations to emphasize clinical usefulness of high-speed imaging. METHOD: Fifty-five men (M age = 36 years, SD = 20 years) were examined and separated into 4 groups: 1 healthy (26 individuals) and 3 pathological (10 individuals with contact granuloma, 12 with polyps, and 7 with cysts). Vocal fold vibrations were recorded using a high-speed camera during sustained phonation. Twenty objective glottal area waveform and 24 phonovibrogram parameters representing spatiotemporal characteristics were analyzed. Statistical group comparisons were performed to document spatiotemporal changes for organic lesions that cannot be determined visually. To look for specific pattern profiles within organic lesions, the authors performed linear discriminant analysis. RESULTS: Thirteen parameters showed significant differences between the healthy group and at least 1 pathological group. The differences occurred more in temporal than in spatial parameters. Contact granuloma showed the fewest statistical differences (3 parameters), followed by cysts (9 parameters), and polyps (10 parameters). Linear discriminant analysis achieved accuracy performance of 76% (all groups separated) and 82% (healthy vs. pathological). CONCLUSION: The results suggest that for males, the differences between healthy voices and organic voice disorders may be more pronounced within temporal characteristics that cannot be visually detected without high-speed imaging.

Neglected laryngeal foreign body.

Laryngeal foreign bodies, especially in children, mostly present as an acute emergency. Few cases of long-standing laryngeal foreign bodies have been reported in the literature. This case illustrates one of the sequelae of a neglected laryngeal foreign body, resulting in significant granulation tissue formation in the larynx, and its management.
