RESUMO
Primary breast cancer is the most common malignancy in women. Metastatic cancer to the breast is very rare. Colorectal cancers usually metastasize to the liver and the lung; other sites of metastasis from colon cancer are uncommon and are usually found in association with extensive liver and/or lung metastases. This is a report of a rare case of aggressive rectal cancer with metastasis to the breast without liver or lung metastases.

Endobronchial stents have been used occasionally to treat benign conditions such as tracheobronchomalacia (TBM). This report describes a unique case of a patient with crescentic TBM in whom Dynamic Y stent was placed on 2 separate occasions to control symptoms and resulted in identical posterior wall stent fractures within a year of stent placement, both times. A silicone Y stent was substituted for the dynamic stent, and it has been effective in controlling symptoms for 9 months without complications. A literature review of cases of fractured Dynamic Y stents is made and factors affecting the choice of stent type for crescentic TBM are explored.
