Background. Breast carcinoma is the most common malignancy in women worldwide. It is most commonly associated with metastases to the liver, lung, bone, and the brain. Invasive lobular carcinoma is a less common pathology with slightly higher metastases to the upper gastrointestinal tract. Invasive lobular carcinoma metastasis to the gallbladder is extremely rare. Method. In this paper we are pr...

INTRODUCTION Invasive lobular carcinomas have an increased propensity for distant metastases, particularly to the peritoneum, ovaries, and uterus. In contrast, distant metastases of nonpalpable lobular carcinomas are extremely rare, and the causes of underlying symptoms of primary carcinomas remain unclear. We report a case of an asymptomatic invasive lobular carcinoma with a primary mammary le...

The differences between invasive lobular and ductal carcinomas affect the diagnostic and therapeutic management for patients with breast cancer. In most cases, this can be accomplished because of distinct histomorphologic features. However, occasionally, this task may become quite difficult, in particular when dealing with the variants of infiltrating lobular carcinoma. Lobular carcinoma has be...

Lobular carcinoma in situ is a form of in situ neoplasia that develops within the terminal lobules of the breast. It is an extremely rare finding in males due to the lack of lobular development in the male breast. The authors herein report an unusual case of incidentally discovered lobular carcinoma in situ in a male patient with recurrent bilateral gynecomastia who was subsequently diagnosed w...

Breast cancer rarely metastasises to the gastrointestinal tract. Lobular carcinoma more commonly metastasises to the uterus and appendages, peritoneum, and gastrointestinal tract than other types of breast cancer, while ductal carcinoma has a propensity to metastasise to the lungs, liver, and brain. We describe the case of a patient with no known history of breast cancer, whose primary presenta...

Lobular carcinoma in situ (LCIS) clinically constitutes a risk factor for the subsequent development of either invasive lobular carcinoma (ILC) or invasive ductal carcinoma (IDC). In order to approach the possibility of this common precursor of both ILC and IDC, we investigated combined lobular and ductal carcinomas. Thirty-two cases of lobular carcinoma were picked up out of 773 cases of opera...

Haematogenous metastases of breast cancer tumors has previously been demonstrated to frequently occur at the sites of the lung, bones, liver and brain, however presence in the uterine remains a rare occurrence. Metastatic carcinoma of the uterus usually originates from other genital sites, most frequently from the ovaries. The current review presents the first reported case of lobular breast ca...

BACKGROUND Colorectal metastasis of lobular carcinoma of the breast is a diagnostic challenge. It may macroscopically simulate primary colon cancer or inflammatory bowel disease. In some cases, the interval between the primary breast cancer and metastatic colorectal lesions is so long that the critical records for diagnosis including history might be lost or missed. CASE PRESENTATION Reported...

The vast majority of invasive breast tumors are ductal and lobular breast carcinomas. Despite the many similarities, some clinical follow-up data and the patterns of metastases suggest that these histological subtypes of breast cancer are biologically distinct. Few papers, however, describe immunohistochemical markers useful for differentiation of these carcinomas. Many investigations suggest t...
