dc.description.abstractIntroduction In most homeothermic vertebrates, pigment cells are confined to the skin, since melanoblast is the only neural crest lineage that can migrate dorsolaterally, between the ectoderm into the derm. Silkie fowl, is a naturally occurring chicken mutant from common chicken, in which pigment cells occupy most connective tissues, given them a dramatic blue-black pigmentation. This occurs because melanoblasts continue to migrate, extensively dorsolateral and ventrally, since the natural tissue barriers, which normally restrain melanoblast migration, are not present in the Silkie fowl. Objectives The authors document, using macro and microscopic figures, the normal distribution of the melanic pigment in the Silkie fowl tissues. Material and Methods 2 adult Silkie fowls were necropsied and samples fixed in 10% neutral-buffered formalin and processed for routine histopathological diagnosis. Results and discussion The distribution of the melanin pigment was observed in the periosteum, perichondrium, connective tissues of adventitia and serosae from several internal organs, as well as in the myocardium, perimysium and endomysium. Conclusion The knowledge of the normal distribution of the melanic pigment in the Silkie fowl tissues allow a better understanding of the histopathological conditions affecting this particular breed.pt_PT
