Primary cutaneous alveolar rhabdomyosarcoma in a pediatric patient

Area of Science:

• Pediatric Oncology
• Dermatopathology
• Surgical Pathology

Background:

• Rhabdomyosarcoma is the most frequent soft tissue malignancy in children, accounting for over half of all pediatric soft tissue tumors.
• While rhabdomyosarcoma can occur anywhere, primary cutaneous involvement is exceptionally rare, posing diagnostic difficulties.
• Soft tissue tumors constitute 6% of all pediatric neoplasms.

Observation:

• A case report details a child presenting with a painful facial nodule.
• Histopathological and immunohistochemical analyses were crucial for confirming the diagnosis.
• The patient was managed by a multidisciplinary team.

Findings:

• The facial nodule was diagnosed as rhabdomyosarcoma.
• The rarity of cutaneous rhabdomyosarcoma underscores the need for thorough diagnostic evaluation.
• Clinical presentation lacks specific features to distinguish it from other skin pathologies.

Implications:

• This case emphasizes the importance of considering rare diagnoses in pediatric dermatology.
• Early and accurate diagnosis of cutaneous rhabdomyosarcoma is vital for timely intervention and improved outcomes.
• Multidisciplinary collaboration is essential for managing complex pediatric cancer cases.
