Abstract

MATUTE, Gustavo; RAIGOZA, Oscar  and  BERTEL, Daniela. Clear cell renal carcinoma metastatic to the breast. rev. colomb. cir. [online]. 2018, vol.33, n.3, pp.311-317. ISSN 2011-7582.  http://dx.doi.org/10.30944/20117582.77.

Introduction:

The presence of breast metastasis from a neoplasm of extramammary origin is an infrequent entity, representing 0.2 to 1.3 % of the non-hematological malignant tumors in breast reported in series of cases; 88.2 % are patients with history of a previously treated primary tumor, and 11.8 % are cases with a hidden primary tumor. The main primary origins of these metastases are cutaneous melanoma, and carcinomas of pulmonary and gynecological origin.

Clinical case:

We present the clinical case of a 59-year-old woman with a history of clear cell carcinoma of the kidney undergoing left radical nephrectomy in 2008, with a palpable breast lesion in the right breast, evidencing a hypoechoic nodule measuring 6.8 x 3.5 mm in the external upper quadrant, whose histopathological study showed a metastatic lesion of primary renal origin.

Discussion:

Approximately 25 cases of metastasis of clear cell carcinoma of the kidney to the breast have been described in the literature, constituting ours an exceptional case, and a diagnostic challenge for the pathologist and the treating team.

Keywords : kidney neoplasms; carcinoma, renal cell; breast neoplasms; neoplasm metastasis.
