RESUMO
Congenital epulis or neonatal granular cell tumor is a tumor whose histogenesis has long been debated. It is dissimilar to other granular cell tumors; the latter having derivation from Schwann cells and hence being S-100 positive. We report a case of congenital granular cell tumor in a newborn female child that was uneventfully operated. The case is reported here because of its rarity.

Granulocytic sarcomas or extramedullary myeloid tumors represent the soft tissue counterpart of acute myeloid leukemia. The term is used for any solid collection of leukemic cells. There have been reports of these tumors occurring before the involvement of blood or bone marrow. Our patient had simultaneous involvement of three sites, which was diagnosed on cytology. Further confirmation was done on peripheral blood and bone marrow evaluation.
