Gall bladder cancer with metastasis to the breast is very rare.

Herein we intend to report a case of carcinoma gall bladder with breast metastasis and a short review of the literature.

Methods : This report describes an interesting and unusual case of gall bladder carcinoma presenting with breast metastasis.

Case report : A 38-year lady presented with complaints of right abdominal pain.

Bilateral breast examination showed 2 _ 2 cm palpable lump in the upper outer quadrant of the left breast.

Contrast-enhanced CT of the abdomen and pelvis showed circumferential thickening of gall bladder with the loss of fat plane with the adjacent liver parenchyma.

Biopsy from the breast lump was reported as metastatic adenocarcinoma compatible with primary in the gall bladder.

Whole body PET-CT showed gall bladder mass with abdominal and pelvic nodes with metastasis to liver, left breast, C7 vertebral body and left supra-clavicular node.

She was diagnosed to have disseminated carcinoma gall bladder with liver, breast and supraclavicular nodal metastasis.

She received palliative chemotherapy with gemcitabine and carboplatin and radiotherapy to C7 vertebra.

After receiving 3 cycles of chemotherapy, chemotherapy was changed to the second line with single agent capecitabine.

In spite of two lines of chemotherapy, she succumbed to disease progression and expired.
