Bilateral Breast Metastasis of Atypical Pulmonal Carcinoid |Biomedgrid

The breast is an uncommon site of metastasis. We report a case of bilateral metastasis of atypical pulmonal carcinoid in the breast. Review of the literature has demonstrated only a few cases of carcinoid metastatis in a single breast, but not bilateral. In spite of the rarity of this finding, the differential diagnosis between primary and metastatic carcinoid or malignant tumor of the breast at all, should be considered in view of the different management of these two settings. Immunohistology has proved a very helpful method in this field. Accurate diagnosis of breast metastasis is important to avoid unnecessary treatment.
