Malignant transformation of abdominal wall endometriosis with lymph node metastasis: Case report and review of literature.

•A simple endometriosis can result in malignancy pathology, as a neoplasia.•Wall-abdominal tumors and soft tissue as a possible differential diagnosis of abdominal wall endometriosis•Preperitoneal node-metastasis as malignancy of endometriosis in previous cesarean scar.

Influence of the in situ component in 389 infiltrating ductal breast carcinomas.

Background: Our aim was to evaluate and compare lymph node involvement, as well as disease-free survival (DFS) and overall survival (OS), between infiltrating ductal carcinoma with (group 1) and without (group 2) intraductal carcinoma component in order to determine the prognostic value of the intraductal component.

Methods: Data from 389 cases of infiltrating ductal carcinoma of the breast were included in the study by means of reviewing medical charts and pathology slides.

Results: There was no statistically significant difference between both groups regarding node status.

[Node status in 454 ductal breast cancers cases according to the association with in situ component].

Background: Studies have shown that breast infiltrating ductal carcinoma develops from precursor lesions or pre-invasive. It is accepted that the risk of invasive ductal carcinoma increased slightly in hyperplasia, but especially in cases of atypical hyperplasia and intraductal carcinoma.

Objectives: To evaluate and compare the nodal status between ductal breast cancer with in situ component (group 1) or without it (group 2).
