Gastrointestinal metastases from breast cancer: a case report. (Case Report).
Breast cancer is the most frequently encountered cancer in women and the second leading cause of cancer death. Distant metastases are present in about 60% of the patients at the time of diagnosis. (1) The lymph nodes, lung, bone, liver, peritoneal cavity, and brain are the usual sites for metastases of breast carcinoma, while gastrointestinal (GI) involvement is rare. (2) Upper GI tract metastases are more frequent than lower GI tract metastases. We herein report a case of upper and lower GI tract metastases occurring many years after the diagnosis of breast carcinoma.
GI metastasis is an underdiagnosed complication of breast cancer. Breast cancer is among the most common primary malignancies metastasizing to the GI tract, along with melanoma, ovary, and bladder. (3,4) Gastric lesions seem to be slightly more frequent (6-18% versus 8-12%) than colorectal ones in postmortem examinations. (5) Median interval between breast cancer and the diagnosis of GI metastasis may vary from a few months to many years (>12 yr). (6-8) Besides gastric and colorectal metastases, reported cases of metastatic breast cancer also present as cholecystitis Cholecystitis Definition
Cholecystitis refers to a painful inflammation of the gallbladder's wall. The disorder can occur a single time (acute), or can recur multiple times (chronic). (9) or as an unusual cause of biliary obstruction due to pancreatic metastasis. (10) Presenting symptoms are sparse, nonspecific nonspecific /non·spe·cif·ic/ (non?spi-sif´ik)

Many studies showed a mainly diffuse linitis plasticalike infiltration: (12) diffuse thickening of the gastric and colorectal wall causing rigidity of the involved segment. Pathologic criteria include infiltration of the serosal, muscular, and submucosal submucosal /sub·mu·co·sal/ (-mu-ko´sal)

containing vacuoles. cytoplasm typically arrayed in chords, named "Indian files." This pattern of infiltration provokes an intense fibrous reaction from the tissues, macroscopically evident as linitis plastica, which occurs both in the stomach and in the rectum. (13) In addition, the "signet ring" morphology of lobular carcinoma may mimic other primary tumors (ie, gastric carcinoma). Correct interpretation of "signet ring" cells as metastatic, most likely from the breast or stomach, is helpful in diagnosis and management. (14) The lack of dysplasia or atypia of the rectal epithelium and the glands surrounding the malignant cells is often helpful in the differential diagnosis between a primary and a metastatic le sion. (11) Immunohistochemistry is the most useful tool to reach the correct diagnosis. Metastatic breast carcinomas are usually positive for gross cystic disease fluid protein-15 (GCDFP-15), cytokeratin 7, carcinoembryonic antigen, estrogen receptor, and progesterone receptors, and negative for cytokeratin 20.

Systemic treatment (chemotherapy and/or hormonal therapy) is usually used. (18) Surgery is indicated mainly in cases of stenosis or complete obstruction. Results are variable. Taal Taal 1

Our patient had a relapse of her breast cancer 14 years after the initial diagnosis. She consulted for constipation and was found to have colonic stenotic lesion and a second ulcerating lesion. Although she was at increased risk for a second primary breast cancer, colonic metastasis from her breast cancer was suspected. She underwent surgery after she developed intestinal occlusion. This is a rare and unusual case of GI relapse many years after the first presentation for a breast adenocarcinoma.
