A 58-year-old woman from Mumbai presents with a 6-month history of spontaneous bloody nipple discharge from the left breast. Physical examination reveals a palpable mass beneath the areola. Mammography and ultrasound show a 1.2 cm mass in the subareolar region with dilated ducts. Ductography reveals a filling defect in the major duct. Excisional biopsy of the mass and involved duct is performed. Histopathology shows a papillary lesion with a fibrovascular core lined by epithelial cells without atypia, and intact myoepithelial layer. What is the diagnosis?
