Splenic papillary angioendothelioma in a 6-year-old girl.

Papillary angioendothelioma is a rare, low-grade neoplasm of lymphatic channels that usually presents intradermally. We report the case of a 6-year-old girl with isolated splenomegaly and symptoms of early satiety and weight loss, whom was found to have a splenic papillary angioendothelioma. Preoperative abdominal computed tomography scan showed an irregular, heterogeneous mass; a tagged red cell scan ruled out a hemangioma, whereas a positron emission tomography scan showed mildly increased uptake. Subsequent surgery and pathologic assessment revealed a papillary angioendothelioma (Dabska tumor) within lymphatic spaces. The child has no evidence of recurrence or metastases 1 year postoperatively.
