Misdiagnosis of laryngeal sarcomatoid squamous cell carcinoma – case report

BACKGROUND. Even if it is a rare variant growth pattern of squamous cell carcinoma, sarcomatoid carcinoma seems to have almost the same clinical manifestations and risk factors as conventional squamous cell carcinoma. CASE REPORT. This paper presents a complex case of a 59-year-old female patient known with laryngeal papillomatosis, who presented in our Department for moderate to severe inspiratory dyspnea associated with dysphonia and difficulty in swallowing. We mention that the patient had been previously evaluated by a pneumologist for apnea, snoring and daytime sleepiness and diagnosed and treated for sleep apnea syndrome. Clinical, laboratory, imaging and pathologic examinations revealed the association of upper airway obstruction with laryngeal cancer. Surgical intervention consisted in total laryngectomy and selective neck dissection associated with permanent tracheotomy. The microscopic appearance was that of a bilateral transglottic sarcomatoid squamous cell carcinoma without metastasis in the right lymph node. CONCLUSION. It is important to evaluate the clinical and imagistic status of patients with laryngeal tumors in order to make a correct decision concerning their treatment policy. We emphasize that cooperation between multiple departments is absolutely necessary in order to adequately resolve, explore, diagnose and treat patients with laryngeal pathology.
