Four cases of thoracic lymphoma mimicking chest wall tumors are presented. As resection is not the treatment of first choice in lymphomas, pretherapeutical evaluation of chest wall tumors should include a thoroughly staging and a biopsy for histopathological diagnosis. Chest wall destruction due to an anterior mediastinal mass, or a chest wall tumor associated with mediastinal lymph node enlarg...

Histopathological changes have been widely used as biomarkers in the evaluation of the health of fish exposed to contaminants, both in the laboratory and field studies. One of the great advantages of using histopathological biomarkers in environmental monitoring is that this category of biomarkers allows examining specific target organ including liver that are responsible for vital functions. A...
