A 57-year-old housewife complaining of choking was admitted to our hospital. Fiberscopic examination revealed a white tumor with a smooth surface and a slight hypervascularity below the vocal cords. A cervical X-ray examination taken from the lateral view revealed that the tumor was located between the area just beneath the vocal cords and the fourth ring of the trachea. Emergent tracheostomy and biopsy of the tumor were performed. Histological diagnosis indicated that the tumor was a small, lymphocytic type B-cell malignant lymphoma (diffuse). No other lesions were detected in the systemic evaluation. After three courses of combined chemotherapy (CHOP), the tumor disappeared. The clinical and pathological characteristics of this case were similar to those of malignant lymphoma of mucosa-associated lymphoid tissue (MALT) which arises in the stomach, salivary glands. lungs. and thyroid.
