[Two further cases of rare laryngeal tumors. Lipoma and chemodectoma (author's transl)].

The cases of laryngeal tumors requiring surgical excision are presented. The first case was that of patient with a laryngeal lipoma of atypical appearance, histological findings suggesting a hamartoma. The second patient had a chemodectoma, diagnosis being difficult but facilitated by super-selective arteriography, requiring delicate excision which was almost bloodless as a result of previous embolization. Clinical and pathological features of these tumors reviewed, and problems related to their treatment discussed. The authors have previously reported 4 other rare types of laryngeal tumor.
