Pathology: Molecular pathology is the study of anomalies of biomolecules, as nucleic acids, proteins, lipids and carbohydrates. Morphological anomalies are microscopical lesions (cellular lesions and tissular lesions) or macroscopical lesions grouped in lesional syndromes. A lesional syndrome can be observed in several diseases. The several thousands of diseases described in humans can be classified according to their causes (etiology and etiological agents) as: genetic diseases (chromosomal diseases and monogenic diseases), infectious diseases, environnemental diseases (toxic diseases, drug-induced diseases), nutritional diseases, dysimmune diseases, senescence-associated diseases, tumors.

Diseases can progress through several physiopathological pathways: malformative, dysimmune, inflammatory, metabolic, toxic (biotoxic), vascular or tumoral.
