FDG PET/CT in a rare case of multiple cutaneous metastases in carcinoma larynx

Abstract

Distant metastases in squamous cell carcinoma of the larynx have an incidence of 6.5-7.2% and most commonly involves the lungs, liver, and bone. Metastases to the skin are very rare, but, when present, they are usually considered a poor prognostic sign. This most often affect the supradiaphragmatic area, i.e., the head, neck, thorax, or upper extremities. We have reported 18F-fluorodeoxyglucose positron emission tomography computed tomography (FDG PET/CT) scan of a patient with squamous cell carcinoma of the larynx showing multiple subcutaneous nodules all over the body, which was helpful in the assessment as well as staging of the disease.
