The adenocarcinoma of the larynx: in aim of a clinic case. Histologic, immuno-histochemistry and electron microscope studies.
Adenocarcinoma "not otherwise specified" of the larynx appears to be extremely rare. We report a case of adenocarcinoma "NOS" arising in the larynx of a 72 year-old white man. The neoplasia was ALCIAN and PAS negative. Immuno-histochemical studies revealed negative immunoreactivity from NSE, chromogranins and S100; cytokeratin was positive. Electron microscopy revealed electrodense granules of varying sizes, but with no obvious central core surrounded by a limiting membrane. The patient underwent a total laryngectomy and functional neck dissection, with mandibular extension. And he is free of tumor after 4 years postoperatively.
