introduction hemangiomas are the most common benign tumor of infancy that can occur anywhere in the body. intramuscular hemangiomas (imh) are accounting for approximately 1% of all cases and the muscles of extremities are the most common sites. because of scarcity and variable clinical features of these tumors, we decided to report a case of imh in the upper lip mucosa. case report the patient ...

Intramuscular hemangiomas of the head and neck are rare congenital vascular tumors and are sparsely reported. Hemangiomas account for approximately 7% of benign tumors and usually present as a mass that suddenly enlarges. Hemangiomas are mostly seen on the trunk and extremities, but can also appear on the head and neck region. A10-year-old boy was referred to our clinic for puffiness and swelli...

BACKGROUND Hemangioma is a benign vascular proliferation. Intramuscular hemangiomas are rare, accounting for less than 1% of all hemangiomas, and occur normally in the trunk and extremities. Approximately 10-20% of intramuscular hemangiomas are found in the head and neck region, most often in the masseter muscles. The typical clinical characteristic is a painful soft tissue mass without cutaneo...

Synovial hemangioma (SH) is a very rare soft tissue tumor; in our department, SH represented 0.07% from all soft tissue tumors (one case from 1311 soft tissue tumors), and 0.78% from all excised hemangiomas (one case from 128 hemangiomas) diagnosed over a five-year period. The aim of this paper was to present the clinicopathologic characteristics of hemangiomas and particularities of one SH of ...

INTRODUCTION Skeletal muscle hemangiomas are uncommon soft tissue tumors; more than 90% are misdiagnosed initially. They present as chronic pain and swelling in a muscle with or without a history of trauma. Magnetic resonance imaging is the investigation of choice. Many treatment modalities for the symptomatic hemangiomas are available of which surgical excision is the most preferred. CASE RE...

Hemangiomas represent the most frequent tumors of infancy. However, the pathogenesis of these tumors is still largely unknown, and current treatment of juvenile hemangiomas remains unsatisfactory. Here we present a novel animal model to study proliferating hemangiomas and to evaluate the effect of angiostatic compounds on their growth. Intraperitoneal (i.p.) infection of 4-day-old rats with mur...

Hemangiomas are between the most frequent soft tissue masses and despite the vascular origin, they do not generate metastases and do not have malignant evolution. They are frequent in childhood and female sex is more frequently affected. If deeply located, these tumors are difficult to diagnose and thus an imaging method is often needed, but conventional radiology is not sufficient. If superfic...

Intramuscular hemangiomas are uncommon neoplasm's arising most frequently in the masseter and trapezius muscle. Due to it's location it is often mistaken for a parotid swelling and rarely is an accurate pre-operative diagnosis achieved clinically. The intra masseteric location also poses special problem in terms of proximity to the facial nerve and the post operative flattening following excisi...

Hemangiomas are the most common benign tumor of soft tissue. They are frequently seen on the trunk and extremities. In addition, most of them exist at the skin and subcutaneous layer, but fewer than 1% does in the intramuscular layer. For the diagnostic images of the intramuscular cavernous hemangioma, ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) are used curre...
