Case ReportCongenital embryonal rhabdomyosarcoma; multiple lesions

- We report a neonate patient with congenital rhabdomyosarcoma that had multiple lesions.
- This rare condition should be considered in the differential diagnosis of neurofibroma and lymphoma in neonates.
- The rapid diagnosis of congenital rhabdomyosarcoma can prevent disease progression by appropriate chemotherapy regimen.
- It was very interesting that lesions were multiple and affected different parts of the body.
- Although bone marrow involvement by embryonal rhabdomyosarcoma is very rare, it should be considered even in early manifestation in a neonate.

IntroductionCongenital or neonatal rhabdomyosarcoma (RMS) is a rare soft tissue tumor with the most common sites of origin in genitourinary tract, head, and neck regions and extremities are less commonly involved.Presentation of caseIn this paper, a case of embryonal RMS with skin lesions, lymph nodes metastasis, and bone marrow metastasis is reported for a 1-month old female patient.DiscussionThis study presents how within 8-months of chemotherapy, the lesions got subsided and the patient became disease free.ConclusionMultiple congenital rhabdomyosarcoma of neonate is a rare finding that should be considered as differential diagnosis of lymphoma and neurofibroma.
