RESUMEN
We report the case of a 17-year-old male who presented with intractable nausea and vomiting. Cross-sectional imaging revealed a large retrogastric abdominal mass. Fine needle aspiration done via endoscopic ultrasound (EUS) was nondiagnostic. Exploratory laparotomy revealed a large inflammatory mass densely adherent to the stomach and retroperitoneum. Incisional biopsy frozen section revealed spindle cells, and subsequent resection of the mass with en-bloc subtotal gastrectomy with Roux-en-y gastrojejunostomy reconstruction was performed. Final pathology demonstrated a lymphatic malformation with reactive myofibroblastic proliferation. Inflammatory abdominal lymphatic malformations are especially rare and not well described in the literature. These masses may present diagnostic challenges until the specimen is sent for pathologic analysis.
RESUMEN
The ameloblastoma, particularly the solid/multicystic type, is the most clinically significant odontogentic tumor. The tumor is often locally aggressive and has a significant impact and may have a patient's morbidity and mortality. In this report, we present a case of a large ameloblastoma that presented with the typical radiographic features of variably sized radiolucent loculations. Microscopically the tumor showed a variety of histologic types, with plexiform and follicular predominating. The tumor was treated with a partial resection of the mandible.
