Syringomatous adenoma of the nipple: report of a case

Syringomatous adenoma of the nipple is a rarely encountered neoplasm of the breast with histological features similar to eccrine syringoma of the skin. This tumour which is locally invasive with high potential for recurrence if incompletely excised is considered benign and a complete excision is sufficient. Hence it deserves recognition by pathologists and surgeons for appropriate management. We report a case of syringomatous adenoma of the nipple in a postmenopausal diabetic woman who was incidentally found to have a subareolar mass in her right breast. Clinical examination and mammographic findings indicated malignancy. Histopathological examination showed features of syringomatous adenoma of the nipple. A clinicopathological study and histological differential diagnosis of this unusual tumour is described.
