MRI appearance of multiple eccrine spiradenoma.

Multiple eccrine spiradenoma is one of the rarest tumours of the sweat gland. We report a case of multiple eccrine spiradenoma that was distributed in several parts of the body. On MRI the lesions presented with multiple dispersive foci with clear circumferences in the cutis and the subcutaneous tissue. The lesions showed low signal intensity on T1 weighted images, and high signal intensity on short tau inversion recovery images. Although the signal intensities of the lesions were not characteristic in this patient, multiple eccrine spiradenoma should be included in the differential diagnosis of the lesions in the cutis and the subcutaneous tissue.
