[Mucous lesions associated with hematologic diseases]

Mucosal lesions are a frequent finding in patients with hematologic malignancies. Early diagnosis and institution of adequate therapeutic modalities can significantly reduce the morbidity and even mortality in these patients. Primary lesions are the consequence of infiltration of the oral tissues by malignant cells. Secondary lesions result from the condition of bone marrow suppression induced by replacement of the blood forming tissue by malignant cells. Lesions caused by the oncologic treatment, directly or indirectly, are called tertiary lesions. This article describes and illustrates the different types of lesions.
