Subcutaneous sarcoidosis associated with vitiligo, pernicious anaemia and autoimmune thyroiditis

We report a patient with pernicious anaemia, primary autoimmune hypothyroidism and vitiligo, who presented with subcutaneous nodules. Histopathology of the nodules revealed noncaseating granulomas, consistent with a diagnosis of sarcoidosis. Mild pulmonary sarcoid was also detected. Although an association between sarcoidosis and other autoimmune diseases is well-recognized, the presence of the particular autoimmune diseases in our patient and the involvement of subcutaneous fat in the sarcoidal inflammation, appears to represent a most unusual clinicopathological combination.
