It is a rare benign mesenchymal tumour;most commonly occurs in infancy or early childhood. The clinical presentation can mimic malignant tumours of infancy or childhood. Case Presentation: We describe a rare case of multicentric Infantile myofibromatosis in a 6-month-old infant presenting with multiple scalp swellings and associated skeletal abnormalities (adducted thumbs, clinodactyly and bilateral hallux valgus deformity of great toes). The case required surgical excision of all scalp lesions and orthopedic manipulation of skeletal abnormalities. Conclusion: Infantile myofibromatosis presenting as multiple lesions in the scalp associated with skeletal abnormalities, is very rare. To best of our knowledge, the unique combination of the distinct skeletal abnormalities in infantile myofibromatosis has not been reported so far. This report emphasizes the possibility of skeletal abnormalities in infantile myofibromatosis.展开更多
