BACKGROUND: Divergent differentiation may not be detected in the limited material available in a fine needle aspiration biopsy (FNAB). CASE: A small round cell malignancy showed neural features ultrastructurally on FNAB, in keeping with primitive neu

BACKGROUND: Gastrointestinal stromal tumors are spindle cell tumors with no specific cell lineage occurring in the gastrointestinal tract and cytologically resemble other benign and malignant spindle cell tumors. Distinctive ultrastructural features
