Classification of adrenal cortical tumors: what limits for the pathological approach?
Most adrenocortical tumors are benign; adrenocortical carcinomas are rare but their prognosis is poor and their therapeutics are sparse. In most adrenocortical tumors, the morphological approach in particular by Weiss system, brings sufficient elements to establish the differential diagnosis between a benign and a malignant tumor. But some tumors of Weiss score of 2 or 3 can raise problems: are they benign, malignant or are they of uncertain malignant potential? On the other hand, some Weiss criteria are difficult to evaluate as, for example, sinusoidal invasion. These observations led to the development of other approaches, in particular genetic approaches. These genetics findings already have repercussions for the patients in the development of molecular markers for diagnosis and prognosis and in the future they could help in the development of new morphological approaches, in particular immunohistochemical approaches.
