A case of adult congenital laryngeal cleft asymptomatic until hypopharynx cancer treatment

Laryngeal cleft is an anomaly of failed posterior closure of the larynx. Most cases are diagnosed and need treatment early in life due to respiratory and swallowing problems. We report an unusual case of a 66-year-old man with an asymptomatic laryngeal cleft until treatment for hypopharyngeal cancer. During concurrent chemoradiotherapy (CCRT), despite reduced tumor volume, he presented severe dysphagia and dyspnea, followed by severe pneumonia twice. Because CCRT had to be discontinued, a pharyngolaryngectomy was performed for the cancer treatment. The resected specimen showed total removal of the tumor and a total longitudinal cleft of the cricoid cartilage, classified as a type III laryngeal cleft by the Benjamin and Inglis’ classification. A review of computed tomography images indicated that the redundant mucosa from bilateral edges closed the separation of the posterior cricoid cartilage and narrowed the laryngeal airway during CCRT. Adult presentations of laryngeal cleft are quite rare with only ten reported cases in English literature; the present case is of the oldest patient. Undiagnosed cases with laryngeal cleft may exist asymptomatically or without severe symptoms. The awareness of this condition may increase its diagnosis as a cause of diseases such as aspiration and recurrent pneumonia even in adult patients.     

Pulmonary metastasectomy for metachronous metastasis of esophageal cancer after esophagectomy

Background and objective

Pulmonary metastasectomy is a standard therapy for some types of metastatic lesions in the lung. Although the prognosis for esophageal cancer patients with pulmonary metastasis is poor, it has been reported that some post-esophagectomy patients have good prognosis after pulmonary metastasectomy. We investigated the role of resecting pulmonary metastases arising from esophageal cancer at our institution.

Patients and methods

Seven patients with primary squamous cell carcinoma or adenocarcinoma of the thoracic esophagus who underwent resection of metachronous pulmonary metastases at our institution between 2006 and 2012 were identified from a retrospective database. All patients had undergone curative resection of their primary esophageal carcinoma.

Results

Six patients had unilateral and solitary lung metastasis. One patient presented with one metastatic lesion on each side, and he underwent 4 metastasectomy for pulmonary metastasis 3 times. There was no perioperative morbidity or mortality. The disease-free interval after esophagectomy ranged from 191 to 559 days (median, 463 days). Survival after pulmonary metastasectomy ranged from 357 to 3191 days (median, 1803 days). Three patients received systemic chemotherapy before metastasectomy. Currently, 5 patients are alive without evidence of recurrent disease.

Conclusion

Pulmonary metastasectomy may be acceptable as a part of multimodal treatment for solitary metachronous pulmonary metastasis in esophageal carcinoma.
