Oral intramuscular hemangioma: Report of three cases

Abstract

Intramuscular hemangioma (IMH) represents less than 1% of all hemangiomas. In the head and neck region, it occurs mostly in the masseter, temporalis and sternocleidomastoid muscles. Despite its infiltrative growth pattern and several worrisome histological features, such as increased mitotic activity, plumpness of the nuclei, intraluminal papillary projections or perineural infiltration, the lesion is benign, and complete surgical excision is the preferred treatment for such oral lesions.Herein, we report three rare cases of IMH in the tongue and lip, discuss the clinical and histological aspects, and review the literature regarding this lesion.

Intramuscular hemangioma in the zygomaticus minor muscle: a case report and literature review

“…Hemangiomas and vascular malformations are benign neoplasms of blood vessels [ 1 , 4 ]. IMH is a special type of hemangioma involving the skeletal muscle that comprises only 0.8% of all hemangiomas [ 2 ]. Clinically, IMH presents as a localized swelling with smooth surface and incompressible borders.…”

“…MRI seems to be a better imaging modality to evaluate IMH than computed tomography [ 4 ]. IMH presents a well-demarcated, bright lesion that has higher signal intensity in T2-weighted images because of the stagnant blood in the vessels [ 2 ]. Angiography may be useful for preoperative embolization if a large feeding artery is adjacent to the mass, but is not routinely performed for the diagnosis of IMH [ 3 ].…”

“…Intramuscular hemangioma (IMH) is a vascular benign proliferation that can occur within any muscle, particularly in the trunk and extremities [ 1 , 2 ]. IMH is an uncommon lesion, accounting for fewer than 1% of all hemangiomas [ 3 ].…”

“…IMH is an uncommon lesion, accounting for fewer than 1% of all hemangiomas [ 3 ]. Head and neck IMH most commonly involves the masseter muscle, followed by the periorbital and sternocleidomastoid muscles [ 2 ]. Clinically, IMH presents as a mass with slow growth, intermittent pain, and no spontaneous decrease in size.…”

Intramuscular hemangioma of masseter muscle: Case report of rare clinical entity

“…[ 1 ] They constitute about <1% of all hemangiomas, only 10%–20% of cases have been found to arise in the head-and-neck (H and N) region, and 36% of cases involving masseter muscle. [ 2 3 ] IMHs usually present as gradually enlarging soft-tissue mass with or without pain. They are located deep within the muscle, hence seldom exhibit clinical signs or symptoms such as bruits, thrills, pulsation which are suggestive of vascular origin.…”
