AIMS The mutual relation of lobular carcinoma in situ (LCIS) and ductal carcinoma in situ (DCIS) of the breast, as accepted precursor lesions of invasive breast cancer, is controversial. Because they display genetic heterogeneity, it is not clear how genetically advanced these entities are and what causes the transition to an invasive carcinoma. METHODS Six cases of LCIS, four of them with as...
Lobular carcinoma in situ (LCIS) of the breast may exhibit a spectrum of morphologic growth patterns and may also colonize underl ying benign breast lesions. This diversity in appearance can create diagnostic challenges, especially in core needle biopsy specimens. Some LCIS variants may mimic ductal carcinoma in situ or invas ive carcinoma. Furthermore, some LCIS variants are frequently associa...
BACKGROUND Invasive pleomorphic lobular carcinoma (PLC) is an aggressive subtype of invasive lobular carcinoma of the breast, which has its own histopathological and biological features. The metastatic patterns for PLC are distinct from those of invasive ductal carcinoma. In addition, pancreatic metastasis from PLC is extremely rare. CASE PRESENTATION We report a rare case of a 48-year-old wo...
INTRODUCTION Solitary uterine metastases from extragenital cancers are very rare. Breast cancer is the most frequent primary site of metastasis to the uterine corpus, with invasive lobular carcinoma more likely to spread to gynecologic organs than invasive ductal carcinoma. CASE PRESENTATION A 62-year-old postmenopausal Japanese woman was diagnosed with uterine leiomyomata more than 20 years ...
There is currently much speculation over the precise nature of lobular carcinoma in-situ of the breast and its significance. Histochemical study shows that it is rich in sialomucin. This has a characteristic intracellular distribution which distinghishes lobular carcinoma in-situ from cancerization of lobules. The same histochemical features are seen in the infiltrative phase of the tumour. The...
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 i...
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...
