Discharge Summary

Patient Name: [REDACTED]   MRN: [REDACTED]

Date of Admission: [REDACTED]       Date of Discharge: [REDACTED]

Admitting Diagnosis: Sarcomatoid gastric carcinoma with hepatic, regional and abdominal metastases.

Hospital Course:

The patient is a 50-year-old female with a medical history significant for diabetes mellitus type 2, hypertension, and cardiomyopathy who presented with sharp abdominal pain in the right upper quadrant for 4 weeks and hematemesis with bright red blood and clots.

A computed tomography (CT) of the abdomen/pelvis with contrast showed a partially exophytic lobular mass along the superior wall of the gastric fundus measuring 4.5 × 4.3 × 2.0 cm, seven lesions within the liver with the largest measuring 2.2 × 2.0 × 2.5 cm, and a metastatic lymph node anterior to the GE junction.

EGD showed a large polypoid fundic mass. H&E staining demonstrated characteristics of gastric carcinoma with final pathological findings of a sarcomatoid carcinoma, which was positive for cytokeratin, SMA, desmin, and GATA3. The mammogram was reported as BIRADS-1, with no evidence of any urothelial mass/neoplasm on the earlier CT scans.

The patient was discharged to follow up with an oncologist. However, she presented again with nausea and vomiting, and a repeat CT of the abdomen/pelvis showed an increase in the gastric mass to 8.7 cm with ulceration and invasion of the left lobe of the liver. There was a massive increase in the regional and hepatic metastases with the largest measuring 10 cm, and there was metastasis to the right adrenal gland with associated ascites. The patient was then transferred to a tertiary care hospital but died before starting therapy.
