An unusual case of intracystic papillary carcinoma of breast with invasive component

Abstract

Papillary carcinoma of the breast is a rare malignant tumor, constituting 1–2% of breast neoplasms mostly affecting elderly postmenopausal women. Intracystic (Encysted) papillary carcinoma (IPC) is a rare distinct entity with slow growth rate and overall favourable prognosis regardless of whether it is in situ alone or associated with invasive component. Treatment modalities vary from conservative surgery to radical surgery with or without adjuvant therapy depending upon the associated component (DCIS or invasive) of the tumor.
