Choriocarcinoma presenting as an isolated bone marrow metastasis-a case report

Gestational trophoblastic diseases (GTD) are a heterogenous group of disorders that arise from trophoblastic epithelium. They can follow molar pregnancy (50%), abortions (25%), normal pregnancy (22.5%), and ectopic pregnancy (2.5%) [Robert JK, Lora HE, Brigitte MR (ed) Blaustein Pathology of the Female Genital Tract 6th edn (Springer) pp. 1101-7]. Occurrence of choriocarcinoma following normal delivery presenting as an isolated bone marrow metastasis is extremely rare, and no case has been cited in the literature, to the best of our knowledge. We are reporting a case of choriocarcinoma that presented with isolated bone marrow metastasis only.
