Introduction:
Rhabdomyosarcoma, though rare in the middle ear, necessitates prompt recognition for optimal management. They are malignant mesenchymal neoplasms arising from the embryonic mesenchymal cells of striated skeletal muscles.
Case Presentation:
We present a case of a 5-year-old child with massive right mastoid swelling and bloody ear discharge. Cytological examination via fine needle aspiration biopsy revealed features suggestive of a malignant mesenchymal tumor, confirmed on imaging and subsequent histopathology as embryonal rhabdomyosarcoma (ERMS) FNCLCC grade 2. Characteristic cytological findings included spindle-shaped cells in a myxoid stroma with tigroid background, aiding in early diagnosis. Despite radical mastoidectomy and adjuvant chemotherapy, ERMS in the middle ear remains challenging due to its aggressive nature and potential complications.
Conclusion:
This case underscores the importance of cytological evaluation in identifying rare soft tissue tumors like ERMS, facilitating timely intervention and improved outcomes. Early recognition and multidisciplinary management are crucial in addressing the complexities of ERMS in uncommon sites like the middle ear.
