Case of concurrent Riedel's thyroiditis, acute suppurative thyroiditis, and micropapillary carcinoma
Riedel's thyroiditis (RT) is a rare chronic inflammatory disease of the thyroid gland. It is characterized by a fibroinflammatory process that partially destroys the gland and extends into adjacent neck structures. Its clinical manifestation can mask an accompanying thyroid neoplasm and can mimic invasive thyroid carcinoma. Therefore, diagnosis can be difficult prior to surgical removal of the ...
Invasive micropapillary carcinoma of the sigmoid colon: distinct morphology and aggressive behavior.
We report a case of invasive micropapillary carcinoma of the sigmoid colon in a 72-year-old female with anemia and abdominal pain. Grossly, the tumor demonstrated a deeply invasive, ulcerated fungating mass. Microscopically, the carcinoma was predominantly composed of micropapillae with reversed cell polarity, abundant neutrophils, and surrounded by clear spaces. Multifocal lymphovascular invas...
Abstract Background Invasive micropapillary carcinoma (IMPC) is a rare malignant breast tumor and variant form of invasive ductal that an aggressive neoplasm the human canine mammary gland. The importance microenvironment in cancer development has gradually been recognized, but little known about cell types outlining cystic space IMPC. This study aimed to characterize neoplastic cells Results I...
PURPOSE Adenocarcinoma with bronchioloalveolar carcinoma (BAC) features is a subtype of non-small cell lung cancers characterized by an intense inflammatory reaction composed of macrophages and neutrophils and by a distinct natural history with intrapulmonary spread leading to death due to respiratory failure. We hypothesized that neutrophils could promote aerogenous spread of lung adenocarcino...
