Recurrence of breast carcinoma as paget's disease of the skin along the core needle biopsy tract after skin-sparing mastectomy

Abstract

We report a case of recurrence as Paget's disease at the core needle biopsy (CNB) entry site in a patient with microinvasive ductal carcinoma who underwent nipple-areola-skin sparing mastectomy (NASSM) and autologous reconstruction. Clinically diagnosed recurrences associated with previous needle procedures for malignant breast lesions are rare and usually occur in patients who have not received radiation therapy. The present case involved local recurrence at the skin puncture site of a patient diagnosed based on CNB findings who underwent NASSM without receiving radiation therapy. Although the removal of the CNB tract with resected breast tissue is not always emphasized, the skin puncture site should be recorded to detect abnormal skin changes after surgery for the timely detection and management of complications.
