Isolated tonsillar sarcoidosis manifested as asymmetric palantine tonsils.
Sarcoidosis is a chronic systemic granulomatous disease of unknown etiology. Isolated sarcoidosis of palatine tonsils in the absence of other systemic localizations is very rare, and only a few cases have been described in literature. We report a case of a 69-year-old woman presenting an asymptomatic unilateral enlargement of palatine tonsils. The pathologic report of the tonsillectomy specimen revealed the presence of noncaseating granulomatous lesions compatible with sarcoidosis. The research of acid-fast bacilli on the biopsy material using the Ziehl-Neelsen stain was negative, and no cultural growth was documented. Further investigations confirmed the diagnosis and excluded other systemic localizations of the disease. In our experience, asymmetric tonsils caused by sarcoid disease should be taken into consideration for the differential diagnosis in tonsillar enlargement. With this report, we underline the possibility of an isolated localization of sarcoidosis in palatine tonsils manifested as asymmetric enlargement, and we point out the value of histopathologic examination after tonsillectomy in selected cases. Once sarcoid lesions are found in tonsillar specimens, further investigations are mandatory to confirm the diagnosis, to detect an eventual multisystemic disease, and to exclude a possible association with malignancy.
