Abstract :
Background: Solid papillary carcinoma (SPC) is considered a rare malignant breast tumor. This tumour can be either in situ or invasive .Both usually show excellent prognosis. Solid papillary carcinoma often shows neuroendocrine differentiation.
Presentation: 74-year-old lady an ulcerative retroareolar mass in the right breast. CECT Thorax revealed a large lobulated fungating ulceroproliferative mass lesion in the right breast with pectoral muscle involvement.without neuroendocrine differentiation.
Conclusion: SPC with invasion is an uncommon variant of papillary carcinoma with frequent mucinous differentiation. Neuroendocrine differentiation although supports the diagnosis of solid papillary carcinoma may or may not be present.
