RESUMEN
Mucosa-associated lymphoid tissue (MALT) lymphoma has specific clinical and pathologic features. The most common site MALT lymphomas is the stomach; however, it can also occur in other organs, such as the salivary glands. MALT lymphoma is rare, but its prognosis is good. A 32-year-old man visited Konyang university hospital with parotid mass. Superficial partial parotidectomy was performed to exclude lymphoid neoplasms. IgH gene rearrangement analysis of the surgical specimen led to the diagnosis of MALT lymphoma. The patient underwent esophagogastroduodenoscopy, positron emission tomography-computed tomography, and whole-body bone scan. Regional or distant metastasis was not observed on staging workup. The patient underwent postoperative radiation therapy, there has been no recurrence of MALT lymphoma to date. Here, we report this rare case of parotid MALT lymphoma that was treated with surgery and postoperative radiation therapy.

OBJECTIVES: A saccular cyst is defined as a dilated saccule of the larynx, filled with mucus, and is located between the false vocal cords and the thyroid cartilage. Although this uncommon laryngeal condition is benign in nature, it could lead to dyspnea, stridor, and airway obstruction, depending on its size and location. Furthermore, some saccular cysts have been associated with laryngeal carcinoma. This study aimed to characterize this rather uncommon laryngeal condition to aid in determining the proper management of this pathology. METHODS: Medical records were retrospectively reviewed of all patients with saccular cysts diagnosed and treated between 2006 and 2017 at a tertiary otolaryngologic care center. RESULTS: Seven patients with saccular cysts were identified (male:female=2:5; mean age, 34.1 years); two were pediatric patients. Surgical intervention was performed in all patients by laryngo-microsurgery using CO2 laser. There was no recurrence after the initial surgical treatment. CONCLUSION: Saccular cysts can be managed endoscopically using CO2 laser, without requiring an external approach. Therefore, an endoscopic approach should be actively considered for an optimal treatment outcome.
