Lack of cellular differentiation with neoplastic-like proliferation in the limbs of the newt Cynops pyrrhogaster.
We report a case of a neoplastic-like proliferation of epidermal cells in the limbs of an adult newt. The undifferentiated cell mass infiltrated the mesodermal tissues. Possible effects of this event on limb regeneration are discussed.
