(A) Excisional biopsy specimen from the left axillary mass showed a multiple cystic lesion in a background fibrosis and focal mature lymphocytes, with an original magnification ×40. (B) The cysts were lined by atypical glandular cells with focal mucinous cells. The glands showed complexity with focal angulated gland, with an original magnification ×400. (C and D) Immunohistochemical studies showed that the glands/cysts were positive for CK7 (C), and positive for Maspin/VHL in a dual staining (D), with an original magnification ×100.
