ABSTRACT
Malignant peripheral nerve sheath tumors (MPNST) are rare heterogeneous group of soft tissue neoplasms. In most cases, they originate within the pre-existing neurofibromatosis. The emergence of glandular structures in MPNST is curious and enigmatic. We report a case of recurrent MPNST with glandular differentiation arising in the background of neurofibroma in a 20-year-old lady. By immunohistochemistry, MPNST showed focal positive staining for S100 and negative staining for SOX10 while adjacent neurofibroma showed diffuse positivity for S100 and SOX10. The glandular tumor cells showed positive staining for CDX2, Cam5.2, CK19, and CK7 (focal), while negative for SOX10 and S100. MPNST with glandular differentiation is quite rare which may pose a diagnostic challenge. The glandular differentiation in MPNST should be excluded from the metastasis from second primary with the aid of clinical and radiological correlation.
