| Right Answer | RightAnswer::A |
| Explanation | [[Explanation::The patient in this scenario is most likely diagnosed with a Krukenberg tumor. A Krukenberg tumor is characterized by the presence of an epithelial and stromal mass, with an epithelial component containing mucin-laden signet ring cells, which have hyperchromatic nuclei and eosinophilic granular cytoplasm. A Krukenberg tumor usually appears as bilateral with signs of lymphatic obstruction. Krukenberg tumors are often diagnosed in patients who are in their 50s. The most common primary site of malignancy is the stomach, warranting radiographic and endoscopic evaluation of the digestive system following diagnosis. Educational Objective: The stomach is the most common primary site of Krukenberg tumors. Work-up to rule out GI involvement is indicated upon diagnosis. |
