Laryngeal spindle cell (sarcomatoid) carcinomas are uncommon tumors, frequently misdiagnosed as reactive lesions or mesenchymal malignancies. The records of 187 patients with tumors diagnosed as laryngeal spindle cell (sarcomatoid) carcinoma were retrieved from the files of the Otorhinolaryngic Tumor Registry of the Armed Forces Institute of Pathology. There were 174 men and 13 women, 35-92 years of age (average, 65.6 years). Nearly all patients experienced hoarseness (n = 165 [88%] patients) for a mean duration of 11.0 months. Patients admitted to smoking (n = 162 [87%] patients) and/or alcohol use (n = 90 [48%] patients). Most tumors were glottic (n = 132 [71%]), T1 (n = 111 [59%]), 1 and polypoid (n = 185 [99%]), with a mean tumor size of 1.8 cm. Histologically, squamous cell carcinoma (n = 157 [84%]) was noted, ulcerated, and blended with the spindle cell component, which was most frequently arranged in a storiform pattern (n = 92 [49%] tumors). Foci of benign or malignant cartilage and/or bone (n = 13 [7%]) were noted in the spindle cell component. All patients were treated with surgery (n = 90 [48%] patients) or surgery with radiation (n = 97 [52%] patients). Recurrences developed in 85 (45%) patients. Overall, T1 glottic tumors managed by complete surgical eradication had the best outcome (mean follow-up, 7.8 years).
