Primary adenocarcinoma of the arytenoid: an ultrastructural study

Intestinal-type adenocarcinoma of the larynx: Report of a rare aggressive phenotype and discussion of histogenesis

BACKGROUND

Primary laryngeal adenocarcinomas are uncommon and typically of salivary or seromucinous glands origin. Similarly, metastatic adenocarcinoma, including intestinal origin to the larynx, is a rare occurrence.

METHODS

We present a case of a 63-year-old woman with odynophagia and an epiglottic mass of 2 months' duration. Physical examination revealed a large mass involving the entire epiglottis with extension to the preepiglottic space anteriorly and to the right lateral wall of the oropharyngeal/hypopharyngeal junction.

RESULTS

Induction chemotherapy was initiated, and, after 4 cycles with no noticeable response, the patient underwent total laryngectomy and bilateral levels II to IV neck dissection. The final pathology diagnosis was primary intestinal-type adenocarcinoma of the larynx.

CONCLUSION

We present a primary high-stage intestinal-type adenocarcinoma of the larynx and discuss its putative origin and the clinicopathologic characteristics.

Primary mucinous adenocarcinoma of the larynx in female patient: a rare entity

Laryngeal malignant tumors are mainly composed of squamous cell carcinomas. Glandular carcinomas of the larynx are rare tumors that constitute less than 1% of all laryngeal malignancies where "adenocarcinoma not otherwise specified" is the most common histologic subtype. Here we report a case of a 70-year-old female patient with primary laryngeal mucinous adenocarcinoma. The rarity of the tumor type and the differential diagnosis of this tumor before reporting it as a primary adenocarcinoma of the larynx are discussed here with literature findings.
