Placental site trophoblastic tumor (PSTT) usually presents with vaginal bleeding or amenorrhea and an enlarged uterus. Metastasis to the skin as the presenting sign, or as a metastatic site, has not been previously reported with PSTT. We report a case of PSTT in which the presenting sign was scalp metastases and the only other disease was a small focus in the uterus. The patient responded to multi-agent chemotherapy and repeated skin resection at the local site. She received 16 alternating cycles of etoposide-methotrexate-actinomycin D and cytoxan-oncovin (EMA/CO) and is currently without evidence of disease. Clinicians caring for reproductive age women should remain aware that gestational trophoblastic disease (GTD) may present in an unusual manner.
