초록
Sparganosis of the breast is an uncommon disease. Cytological granulomatous inflammation is a common feature of sparganosis. The presence of larval fragments is necessary for a definitive diagnosis of sparganosis in a cytological specimen. However, calcareous corpuscles entrapped in necrotic debris can be very diagnostic for sparganosis in endemic areas. We experienced three cases of mammary sparganosis diagnosed by fine needle aspiration cytology before surgical excision. Two cases showed numerous calcareous corpuscles associated with necrotic debris thought to be degenerated parasitic bodies. The remaining case revealed a few degenerative calcareous corpuscles and parasitic bodies. The presence of calcareous corpuscles and/or degenerative parasitic bodies can be an aid in the differential diagnosis between sparganosis and other forms of granulomatous mastitis, particularly in endemic areas of sparganosis.
Abstract

We experienced three cases of mammary sparganosis diagnosed by fine needle aspiration cytology before surgical excision. Two cases showed numerous calcareous corpuscles associated with necrotic debris thought to be degenerated parasitic bodies. The remaining case revealed a few degenerative calcareous corpuscles and parasitic bodies. The presence of calcareous corpuscles and/or degenerative parasitic bodies can be an aid in the differential diagnosis between sparganosis and other forms of granulomatous mastitis, particularly in endemic areas of sparganosis.
