A 28-year-old man presents with a mass in the left neck region.

Intramuscular hemangiomas are relatively unusual benign tumors that occur more often before the age of 30. They are more common in young adults with no gender predilection. Histologically, intramuscular hemangiomas may be capillary, cavernous, or with combined features. Even though these tumors are benign, they may have an infiltrative growth pattern. Because of such infiltrative growth patterns, these tumors often have a tendency to recur.
