INTRODUCTION: Core needle biopsy has become the preferred method of diagnosing @entity0 prior to definitive surgery. The possibility of displacing @entity5 cells into the needle track is a concern. PRESENTATION OF CASE: A 38 year old @entity1 was diagnosed with @entity0 in situ (DCIS) with microinvasion by core needle biopsy. Bilateral skin sparing mastectomies with immediate autologous reconstruction were performed. One and a half years later the @entity1 noted erythema and a scaling crust on the skin of the right breast that progressed over several months. Punch biopsy revealed @entity4261 restricted to the epidermis. Subsequent comparison to initial clinical photographs confirmed the @entity5 was associated with the skin puncture site of the needle biopsy. The @entity1 underwent complete excision with skin grafting and remains free of disease three years later. DISCUSSION: Only 13 cases of needle track recurrences have been reported. The majority presented as invasive @entity189 forming a subcutaneous mass. In the current case, detection was delayed due to not initially noting that a @entity272 was at the puncture site of the original needle biopsy. This is the only case of recurrence as @entity5 limited to the epidermis. CONCLUSION: Although recurrence in a needle track occurs very infrequently, clinicians should be aware of this phenomenon and investigate any changes, particularly when occurring at a needle biopsy site. Recording the skin puncture site can aid in early detection of recurrences. Recognition of a recurrence is important for prompt treatment and optimal prognosis.
