Solid variant of papillary carcinoma of nipple: An under recognized entity

Papillary lesions of the breast represent a heterogeneous group with differing biological behavior. Solid papillary carcinomas are uncommon tumors composed of circumscribed large cellular nodules separated by bands of fibrosis. Correct diagnosis is crucial but may be difficult, as many other benign and malignant lesions have similar histological appearances. Immunohistochemistry plays a useful role in their differentiation. We describe one such case of a solid variant of papillary carcinoma of the left nipple in a 75-year-old woman, who had no other palpable mass in rest of the breast tissue. The case is documented for the rarity of its occurrence and significance of recognition of this lesion
