Two cases of laryngeal angiomyoma which developed in 51 and 52‐year‐old men are reported. One was a tumor found in the supraglottic area of the larynx and the other was in the subglottic space. Each was a spherical tumor with a smooth surface. The chief complaints of these patients were sudden dyspnea, hoarseness, and laryngeal pain. The tumors were removed through direct laryngoscopy under general anesthesia; but in both cases, considerable bleeding occurred during and after surgery. Histological examination showed that the tumor was covered by squamous epithelium and a fibrous capsule. The parenchyma of the tumor was composed of proliferated fibers of smooth muscle, and dilated blood vessels in abundance. The tumor is of benign nature and recurrence is rare. For therapy, therefore, complete extirpation of the tumor is adequate, but the likelihood of profuse bleeding must be considered.
