this is a case of 硬化性結節症(tuberous sclerosis)
A rhabdomyoma is a benign tumor of striated muscle. Cardiac rhabdomyomas are the most common primary tumor of the heart in infants and children.
It has an association with tuberous sclerosis.[1]
It is most commonly associated with the tongue[2] and heart,[3] but can also occur in other locations.
The malignant form of rhabdomyoma is called rhabdomyosarcoma.
