PURPOSE Application of current nodal status classification is complicated in lobular breast carcinoma metastases. The aim of this study was to define the optimal interpretation of the pTNM classification in sentinel node (SN) -positive patients to select patients with limited or with a high risk of non-SN involvement. PATIENTS AND METHODS SN metastases of 392 patients with lobular breast carcinoma were reclassified according to interpretations of the European Working Group for Breast Screening Pathology (EWGBSP) and guidelines by Turner et al, and the predictive power for non-SN involvement was assessed. Results Reclassification according to definitions of EWGBSP and Turner et al resulted in different pN classification in 73 patients (19%). The rate of non-SN involvement in the 40 patients with isolated tumor cells according to Turner et al and with micrometastases according to EWGBSP was 20%, which is comparable to the established rate for micrometastases. The rate of non-SN involvement in the 29 patients with micrometastases according to Turner et al and with macrometastases according to EWGBSP was 48%, which is comparable to the established rate for macrometastases. Therefore, the EWGBSP method to classify SN tumor load better reflected the risk of non-SN involvement than the Turner et al system. CONCLUSION Compared with the guidelines by Turner et al, the EWGBSP definitions better reflect SN metastatic tumor load and allow better differentiation between patients with lobular breast carcinoma who have a limited or a high risk of non-SN metastases. Therefore, we suggest using the EWGBSP definitions in these patients to select high-risk patients who may benefit from additional local and/or systemic therapy.

We present a patient with a history of infiltrating lobular breast carcinoma that metastasized to both the biliary and urinary tract after a ten year disease-free period following mastectomy and chemoradiotherapy. The patient presented with acute cholecystitis; imaging and histopathology revealed infiltrating lobular carcinoma of the gallbladder and urinary bladder. This report emphasizes the importance of long-term follow up in patients with a history of breast cancer and maintaining a high degree of suspicion for diagnosis of metastatic disease.

Gastrointestinal metastases are rare. May occur years after initial diagnosis and its symptoms are nonspecific, delaying its correct diagnosis and aggravating its prognosis. The most common histological subtype is lobular breast carcinoma. We present a 75-year-old woman with history of left mastectomy six years ago by infiltrating lobular carcinoma. She was treated with tamoxifen for five years. At present, there was no evidence of disease. She attended the hospital for intestinal subocclusion, being admitted for study. A barium enema revealed multiple strictures of the large bowel and a colonoscopy revealed an impassable stricture in the rectum-sigma. Due to the severity of symptoms, underwent total colectomy. The suspected diagnosis was Crohn's disease. The surgical specimen showed multiple stenosis of the light, with thickened wall and mucosa with granulations. Microscopic examination showed transmural infiltration of colonic wall by malignant cells CK7 positive and ER positive. Breast infiltrating lobular carcinoma has more special tendency to affect the digestive tract, even many years after the diagnosis of the primary tumor. In front of a patient with history of breast cancer and gastrointestinal symptoms, its mandatory to consider gastrointestinal metastases, making differential diagnosis with inflammatory bowel disease, infections or primary tumors, as the therapeutic actions are different.

Gastrointestinal metastases from invasive lobular breast cancer are uncommon with the stomach and small intestines being the most common metastatic sites. Peritoneal and rectal metastases are very rare and only rarely occur as the first manifestation of disease. We herein report the case of a 47-year-old woman who presented with abdominal carcinomatosis as a first sign of invasive lobular breast carcinoma (ILC). Identifying the most important immunohistochemical markers for ILC: gross cystic disease fluid protein 15, estrogen and progesterone receptors enabled a correct diagnosis. After a six year disease-free period, relapse occurred with severe obstruction due to rectal metastasis from lobular breast carcinoma. Since there was no widespread metastatic disease, surgery with concomitant hormonal therapy was performed.

Gallbladder metastasis of breast cancer are rare, particularly linked to lobular histotype and synchronous just in 1/4 cases. A review of the literature has been performed aimed to evidence the patterns of gallbladder metastases of breast cancer finding 15 cases to whom we added a 48 years old post-menopausal woman. 3 weeks after surgery for mixed ductal-lobular breast carcinoma she showed at the abdominal ultrasound, performed for staging, diffuse thickening of the gallbladder wall , coherent with a chronic cholecystitis and with the mild right-upper-abdominal pain that the patient complained in the last months. After laparoscopic cholecystectomy, the pathology report showed a metastatic lobular carcinoma of the breast. Two years later she presented with SNC metastases and died four months later. Lobular histotype is the most frequent breast neoplasm associated with gallbladder metastases. Usually metachronous, these metastases are sinchronous in 28% of cases. Symptoms are usually linked to coexisting acute or cronic cholecystitis. Rarely massive invasions lead to acute abdomen or jaundice. Imaging is rarely diagnostic for neoplasm. Our experience and data from literature lead to careful evaluate every anomaly observed in breast cancer patients. A careful evaluation of abdominal symptoms and of routine imaging examinations performed for staging and for treatment planning, could consent to detect and radically treat the metastases and appropriately assign the chemotherapy. Such approach can lead to discrete survival even in these unfortunate patients. Surgeons and gastroenterologists should be aware of the risk hidden behind apparently benign, mild diseases in such patients.

Tumor to tumor metastasis is a rare phenomenon, in which one, benign or malignant, tumor is involved by metastatic deposits from another. Most documented tumor to tumor metastases have been located intracranially, in which, in the majority of cases, either a breast or a lung carcinoma metastasized to a meningioma. Only 7 cases of metastases to schwannoma have so far been reported in the English literature, in 6 cases to an intracranial acoustic schwannoma and in a single case to a subcutaneous schwannoma. We present a case of dermal/subcutaneous plexiform schwannoma containing metastatic deposits of an occult lobular breast carcinoma, creating a unique schwannoma with epithelioid cells. Differential diagnosis of schwannoma with epithelioid cells includes malignant transformation of schwannoma and metastasis of a carcinoma or melanoma to schwannoma, epithelioid schwannoma, and schwannoma with glandular or pseudo glandular elements.

Invasive ductal and lobular breast carcinomas often have different preferred metastasis sites and distinct histomorphologic characteristics. Their metastatic cytomorphologic cell features in body cavity fluids are generally readily recognized, but the single-cell/mesothelial-like pattern and its relationship to the primary tumor type have not been well studied, nor whether metastases have a propensity for certain body cavity sites on the basis of the primary tumor type. To further assess the tumor type and single-cell pattern of breast carcinoma metastases in pleural and peritoneal effusions, we retrospectively studied 853 pleural and peritoneal effusions and correlated the findings with the primary tumor type. When necessary, the single- cell/mesothelial-like pattern was documented immunohistochemically. Metastatic breast carcinomas represented 249 (50.8%) of 490 pleural and 51 (14.0%) of 363 peritoneal effusions. Most metastases in pleural and peritoneal effusions were ductal carcinomas (92.4% and 62.7%, respectively). Lobular carcinoma accounted for only 2 (0.8%) of 249 pleural and 11 (21.6%) of 51 peritoneal effusions. The single-cell/mesothelial-like cell pattern was found in all lobular carcinomas but also in 11 (6.0%) of 184 reviewed ductal carcinomas (nine pleural and two peritoneal). Awareness of these findings and the use of immunohistochemical analyses are necessary for accurately diagnosing metastatic breast carcinoma, especially lobular type.

The breast carcinoma metastases preferentially in the axillary lymph nodes, bones, lungs, liver and soft tissues. Gastrointestinal or bladder dissemination is very rare. We report the case of a 63-year-old female with a clinical presentation of acute cholecystitis, who underwent laparoscopic cholecystectomy in emergency. The gallbladder showed a nodule at the infundibulum, which was responsible for the gallbladder hydrops with macroscopic features of a cholangiocarcinoma. Histological examination disclosed a metastasis from a lobular breast carcinoma with positive hormone receptors, but no overexpression of the Neu oncogene. Immunohistochemistry showed positive staining for cytokeratin7 suggesting a lesion of breast origin. The absence of E-cadherin was consistent with lobular carcinoma while negative CA 19.9 excluded cholangiocarcinoma. The patient had received 15 years previously a right mastectomy with axillary dissection followed by chemotherapy and radiotherapy for breast carcinoma of ductal type labeled SBR stage III, pT3N1 M0, showing hormone receptors but absent Neu oncogene. Proofreading of the mastectomy histological slide concluded that it was a lobular rather than a ductal type carcinoma, confirming the finding of a gallbladder metastasis 15 years after the mastectomy. The patient showed no local recurrence or contralateral lesions on magnetic resonance imaging (MRI). The bone scan showed metastases in the skull, scapula, right rib cage, thoracolumbar spine and pelvis, also confirmed by MRI. A treatment with exemestane and zoledronic acid was introduced. The follow-up at 6 months showed regression of the bone lesions and absence of parenchymal new locations.

Introduction. Breast cancer is the most common nondermatologic cancer in women. Common metastatic sites include lymph nodes, lung, liver, and bone. Metastases to the bladder are extremely rare, with all reported cases presenting with urinary symptoms. Case Report. Herein, we report the first case of completely asymptomatic bladder metastasis from breast cancer, occasionally revealed, 98 months after the initial diagnosis of lobular breast carcinoma, by a follow-up computed tomography scanning showing thickening of left bladder wall and grade II left hydronephrosis. A positive staining for estrogen and progesterone receptors was confirmed by immunohistochemistry. Discussion. The reported case confirms that bladder metastases from breast cancer tend to occur late after the diagnosis of the primary tumor and, for the first time, points out they can be asymptomatic. Conclusion. Such data support the need for careful follow-up and early intervention whenever such clinical situation is suspected.
