Papillary adenoma of
the nipple: analysis of fifteen new cases.
J Am Acad Dermatol. 1985 Apr; 12(4):707-15.
Fifteen cases of
papillary adenoma (florid papillomatosis, erosive adenomatosis) of the
nipple were compared with forty examples of syringadenoma papilliferum,
twenty-four of hidradenoma papilliferum, and one hundred of breast
carcinoma metastatic to skin. Clinically, papillary adenoma of the
nipple typically occurred in a female patient as an erosion,
ulceration, or mass that was sometimes accompanied by serous or bloody
discharge from the nipple and was frequently misdiagnosed as Paget's
disease. Histologically, there was usually a papillary and adenomatous
growth in the corium that connected with the surface and showed a
lining of apocrine type secretory epithelium, a sometimes plasmacytic
stroma, and horn cysts in the upper corium. Papillary adenoma of the
nipple is often histologically misinterpreted as syringadenoma
papilliferum, hidradenoma papilliferum, or low-grade adenocarcinoma,
but it has received almost no attention in the dermatology literature.
