Tall Cell Variant of Invasive Papillary Breast Carcinoma

Tall cell variant of invasive papillary breast carcinoma is exceedingly rare, with only 30 cases reported in the literature. This report describes a case of a 47-year-old woman who presented to the clinic with bilateral breast masses on a screening mammogram. The patient was lost to follow-up, but she presented again after 4 years when the right breast mass significantly grew in size over several months. Mammography showed a 1.9 cm right breast mass and a 2.3 cm left breast mass. Ultrasound-guided core biopsy revealed right breast triple negative invasive carcinoma of the tall cell papillary variant and left breast fibroadenomatoid nodules. She underwent bilateral lumpectomies with a right sentinel lymph node biopsy and was started on chemotherapy after surgical excision.
