Summary
This study reports the first case of a vulvar encapsulated solid papillary carcinoma with neuroendocrine differentiation. Early diagnosis is crucial due to its unique biological behavior.
Area of Science:
- Gynecologic Pathology
- Surgical Oncology
- Neuroendocrine Tumors
Background:
- Vulvar masses require accurate histopathological diagnosis.
- Neuroendocrine differentiation in vulvar neoplasms is rare.
Observation:
- A 40-year-old woman presented with a painless vulvar mass.
- Histopathology revealed an encapsulated solid papillary neoplasm with moderate nuclear atypia.
- Immunohistochemistry showed positivity for GCDFP-15, synaptophysin, and chromogranin, and negativity for myoepithelial markers.
Findings:
- The tumor was diagnosed as an encapsulated solid papillary carcinoma with neuroendocrine differentiation.
- The absence of myoepithelial cells and presence of neuroendocrine markers were key diagnostic features.
- The patient remained disease-free for 4 years post-excision.
Implications:
- This case highlights a rare vulvar tumor with distinct characteristics.
- Accurate diagnosis is essential for appropriate management and prognosis.
- Further research into the behavior of such tumors is warranted.
