Pregnancy-associated anaplastic large-cell lymphoma of the breast: a rare mimic of ductal carcinoma.
Anaplastic large-cell lymphoma (ALCL) is a rare T-cell lymphoma typically seen in children and young adults. It has been described in numerous sites; however, the breast is one of the least common locations. We herein report a case of ALCL arising in the breast of a 36-yr-old pregnant woman. To our knowledge this is the second such case in the English literature. We would like to highlight the cytologic and histologic features of ALCL, as this case was initially misdiagnosed as a ductal carcinoma. Differential diagnosis with other tumors is also discussed. This case serves to emphasize the importance of the triple test, and the need for correlation of fine-needle aspiration findings with core biopsy findings in breast tumor management.
