Insights
Deep soft tissue leiomyomas are rare in children. This case highlights a misdiagnosed leiomyoma in a child
Area of Science:
- Oncology
- Pediatric Oncology
- Soft Tissue Tumors
Background:
- Deep soft tissue leiomyomas are uncommon, typically affecting adults aged 40-60.
- These benign tumors predominantly occur in women, with the uterus being the most frequent site.
Observation:
- A rare case of deep soft tissue leiomyoma in the foot of a 5-year-old male is presented.
- The tumor was initially misdiagnosed as desmoid-type fibromatosis based on imaging and biopsy results.
Findings:
- The leiomyoma's unusual presentation in a young child and its foot location are notable.
- Magnetic resonance imaging and ultrasound-guided needle biopsy failed to accurately diagnose the lesion.
Implications:
- This case underscores the diagnostic challenges posed by rare pediatric soft tissue tumors.
- Emphasizes the need for multidisciplinary evaluation at specialist centers for complex pediatric oncology cases.
Abstract:
Leiomyomas of the deep soft tissue in the extremities of children are very rare. These benign soft tissue tumors occur more frequently in adults between the fourth and sixth decades of age. Women are more commonly affected than men, with the uterus the most common location. We present a rare case of deep soft tissue leiomyoma in the foot of a 5-year-old male. The tumor was misdiagnosed as a desmoid-type fibromatosis from the findings of both magnetic resonance imaging and needle biopsy. The unusual age of presentation, atypical location, and failure of magnetic resonance imaging and ultrasound-guided needle biopsy in diagnosing the lesion make the case interesting. The case also highlights the importance of treating such patients at specialist tertiary centers with a multidisciplinary setting.
