Summary
Rhabdomyosarcoma, a rare cancer, can present as skin nodules on the face in children and adults. Early biopsy is crucial for timely diagnosis of this soft tissue sarcoma.
Area of Science:
- Oncology
- Dermatology
- Pediatric Oncology
Background:
- Rhabdomyosarcoma is a malignant soft tissue tumor originating from mesenchymal cells.
- Dermal presentations of rhabdomyosarcoma are uncommon, often leading to diagnostic challenges.
Observation:
- Two patients, a 12-month-old and a 19-year-old female, exhibited facial dermal nodules.
- The nodules progressively enlarged over months, initially appearing as small papules or masses.
Findings:
- Biopsies confirmed rhabdomyosarcoma with extension from soft tissue into the dermis in both cases.
- The clinical presentation of asymptomatic dermal papules lacked distinctive features, potentially delaying diagnosis.
Implications:
- Recognizing rhabdomyosarcoma as a rare cause of facial dermal nodules is critical for prompt diagnosis.
- Histopathological examination via biopsy is essential for differentiating these lesions from benign conditions and ensuring appropriate treatment.
