Introduction: Neuroblastoma-like schwannoma is a rare morphologic variant of schwannoma with formation of large rosettes.
Case Report: A 29-year-old woman presented with a longstanding left chest wall soft tissue mass. Histology showed small monomorphic tumor cells radially arranged around a fibrocollagenous core forming large rosettes. No evidence of mitotic activity or necrosis was identified. Diffuse S100 reactivity by immunohistochemistry helped confirm the diagnosis as neuroblastoma-like schwannoma.
Conclusion: Awareness of this unusual variant of schwannoma will avoid misinterpretation and confusion with other benign and malignant rosette forming tumors.
Keywords: Neuroblastoma, Rosette, Schwannoma
