Gross image shows an intramuscular myxoma. This is a circumscribed and lobulated tumor with a white or glistening cut surface. Note the smooth interface with adjacent skeletal muscle.






In this intramuscular myxoma, the lesion abuts skeletal muscle image. The lesion is sparsely cellular; the constituent cells are small and bland and arranged in patternless distributions within the myxoid stroma.
