[Pulmonary non-Hodgkin's lymphoma that arose in mucosa-associated lymphoid tissue of the salivary gland and was diagnosed at autopsy].
A 70-year-old woman complained of a dry mouth and swelling in the area of the left parotid gland for 6 years, and was admitted for evaluation of an abnormal shadow on chest X-ray film. She underwent a lip biopsy and a 99mTcO4- scintigram of the salivary gland, and Sjögren's syndrome was diagnosed. Histopathological examination of the percutaneous lung biopsy specimen showed pseudolymphoma, and examination of a specimen of the left parotid gland tumor showed myoepithelial sialadenitis. The patient died of respiratory failure due to a right pleural effusion 4 years later. Autopsy revealed pulmonary non-Hodgkin's lymphoma (diffuse, large, B cell, IgG) with monotonous infiltration of centrocyte-like cells. A retrospectively resected specimen of the left parotid gland tumor showed non-Hodgkin's lymphoma similar to that found in the autopsied lung. This patient probably had pulmonary non-Hodgkin's lymphoma that arose in mucosa-associated lymphoid tissue of the salivary gland and was associated with Sjögren's syndrome.
