BACKGROUND There has been no definitive consensus regarding the causal relationships between foreign bodies in the breast and carcinogenesis. This report describes the first case of invasive micropapillary carcinomas after augmentation mammoplasty. Multiple tumors located in immediate contact with the siliconomas suggested a causal link between the siliconomas and carcinomas. CASE PRESENTATIO...

We previously reported that polyploid giant cancer cells (PGCGs) induced by CoCl2 could form through endoreduplication or cell fusion. A single PGCC formed tumors in immunodeficient mice. PGCCs are also the key contributors to the cellular atypia and associate with the malignant grade of tumors. PGCCs have the properties of cancer stem cells and produce daughter cells via asymmetric cell divisi...

Mixed squamous cell and glandular papilloma (mixed papilloma) is a rare, benign, pulmonary neoplasm and most commonly found in senile patients with male predilection. There were only 18 cases reported so far in the English literature. We herein present one case of mixed papilloma in a 61-year-old male patient. Contrast-enhanced computed tomography scanning revealed a solitary nodule in the infe...

Micropapillary serous borderline tumor of the ovary is characterized by a more frequent association with extraovarian, especially invasive, implants. The aim of this study was to report the clinicopathological findings of a rare case of micropapillary serous borderline tumor of the ovary since there are less than 100 similar cases in the published literature. Additionally, the successful manage...

Adenomyoepithelioma (AME) is a rare benign tumor composed of myoepithelial cells (MECs) which are located beneath the epithelial cells of exocrine glands, especially in breast and salivary glands. These tumor cells show biphasic proliferation of epithelial and MECs. Malignant AME is characterized by distant metastasis, local recurrence, cytologic atypia, high mitotic activity and infiltrating t...

Invasive micropapillary carcinoma (IMPC) of the breast, urinary bladder, ovary, and colon has been reported. However, few reports have described IMPC of the stomach. In addition, IMPC has been described as a histological indicator for lymphatic invasion and nodal metastasis, resulting in poor prognosis. We report a case of 5-year survival after surgery for IPMC of the stomach. A 69-year-old wom...

Objective: To investigate the correlation between clinico-pathological features and lymph node metastasis of thyroid micropapillary carcinoma (PTMC). Methods: data 142 cases were collected, relationship sex, age, tumor location, multi-focality cervical was analyzed. Results: There a high rate in male patients with PTMC. no significant multifocality metastasis. Conclusion: The histological subty...
