Jejunal Leiomyosarcoma in a Young Adult: Distinguishing from Gastrointestinal Stromal Tumor through Radiographic, Histologic, and Epidemiologic Analysis - A Case Report.

INTRODUCTION

Primary small intestinal malignancies are rare with an incidence of less than 5% of all gastrointestinal malignancies and are more common in the middle-aged and elderly population. They are comprised either an adenocarcinoma, neuroendocrine tumor, gastrointestinal stromal tumor (GIST), lymphoma, and/or sarcoma.

CASE PRESENTATION: Here we exhibit the case of a 23-year-old who presented with progressive nausea, weight loss, abdominal pain, and iron deficiency anemia and was diagnosed with leiomyosarcoma of the jejunum.

CONCLUSION

We distinguish a GIST from leiomyosarcoma based on radiographic, histologic, and epidemiologic evidence and review the significance of prompt, accurate diagnosis as related to treatment.
