Some authors have speculated that certain lymphomas should also be included.3The evidence presented in favor of a unitary view of this group of illnesses usually consists of (1) the common ancestry, in the primitive multipotential mesenchymal cell, of the cell lines involved in the clinical entities listed; (2) the frequent observation of intermediate forms, that is, features characteristic for several of the clinical entities seen in the same patient; (3) the natural evolution of any one of these entities into one another.It is with respect to the last point that
