Frantz's tumor as incidental finding during Heller myotomy for achalasia: case report and review of literature.

INTRODUCTION

Solid pseudopapillary tumor is a low-grade malignancy of the pancreas and predominantly affects young women. This neoplasm is a rare pancreatic entity with vague clinical presentation. Diagnosis is often incidental through imaging or even during surgical approach for another condition.

CASE PRESENTATION

A 22-year-old Brazilian female with gastrointestinal symptoms was diagnosed with achalasia and underwent Heller myotomy. Intraoperatory findings included an enlarging mass in the distal pancreas. During follow-up for the surgical approach of achalasia, a hypothesis of Frantz's tumor was stated, and spleen-preserving distal pancreatectomy was performed.

DISCUSSION

The pathological pathways of Frantz's tumor is still unclear, and its connection with chromosomal abnormalities is under investigation. Although the tumor has been reclassified over the years to solid pseudopapillary tumor, surgical resection remains the standard treatment.

CONCLUSION

Despite a surgical challenge, surgery presents a great prognosis in these patients and long-term survival. High suspicion and proper investigation are fundamental to diagnosis and early treatment.
