Skin uptake of Gallium 67 in cutaneous sarcoidosis.

A patient is presented with cutaneous sarcoidosis of the scalp. Ga-67 was intensively taken up by the skin lesions. Systemic involvement of parotid glands and mediastinum was also demonstrated by Ga-67 scintigraphy. Prednisolone therapy reversed promptly the pathologic Ga-67 uptake. Ga-67 scintigraphy should be performed in all patients suffering from cutaneous sarcoidosis as being the most sensitive method to demonstrate systemic involvement.
