“…Nine of the 13 angioleiomyomas showed this vascular pattern, a statistically significant result ( P = .029). Sardanelli et al 5 reported that angioleiomyomas on color Doppler sonography showed more regular intranodular vascular flow than that seen in soft tissue hemangiomas. Latifi and Siegel 6 reported the vascular pattern of hemangiomas to show only central flow, with a patchy color Doppler signal, which resembled our vascular pattern type 3, or with branches coursing peripherally and with centrally scattered color flow, as in our type 2.…”

“…Many previous studies reported pain as the most striking clinical feature of angioleiomyomas, the cause of which is thought to be the active contraction of smooth muscles resulting in local ischemia 4 . Sardanelli et al 5 suggested that the diagnosis of an angioleiomyoma should be considered in all patients with a painful palpable nodule in the extremities, particularly female patients. In practice, however, many patients do not have pain.…”

“…In our study, homogeneous hypoechogenicity was a statistically significant feature based on gray‐scale sonography ( P = .001). Previous studies insisted that sonographic findings suggestive of angioleiomyomas include a circumscribed margin, hypervascularity, and a small size (<2 cm) 1 , 5 . Gomez‐Dermit et al 3 reported the mean size of angioleiomyomas as 2 cm, and 9 of their 10 cases had an ovoid shape.…”

Objectives The purpose of this study was to evaluate the sonographic features of angioleiomyomas with priority given to the vascular pattern to help in the differential diagnosis from other hypervascular soft tissue tumors. Methods The inclusion criteria for this retrospective and nonblinded study were fulfilled in 33 patients with circumscribed hypervascular soft tissue tumors based on pathologic identification. Thirteen cases were angioleiomyomas; 9 cases were nonsubungual glomus tumors; and 11 cases were hemangiomas. Two musculoskeletal radiologists interpreted the results by consensus. Sonographic findings, including the shape, size, echogenicity, vascular pattern, and vascular density of the angioleiomyomas, were compared with those of the other hypervascular tumors. Vascular patterns were categorized into 3 vascular types: 1, several linear vessels clustered in the tumor with convergence to one point; 2, diffusely scattered irregular vessels in the tumor, and 3, one or more vessels that were centrally located. The vascularity of the mass was also categorized as rich (covering >50% of the area of the lesion), moderate (between 20% and 50%), and little (<20%). Results All of the angioleiomyomas were hypoechoic (100% [13 of 13]), a statistically significant result (P = .001). The type 1 vascular pattern was observed in 69% of the angioleiomyomas (9 of 13; P = .029), and the statistically significant shape was round (38% [5 of 13]; P = .035). Conclusions Most angioleiomyomas reveal a homogeneously hypoechoic echo texture with a circumscribed margin and show straight and linear vessels in the tumor with convergence to one point on color Doppler sonography. These characteristics may be helpful when differentiating angioleiomyomas from other circumscribed hypervascular soft tissue tumors.

Angioleiomyoma is a benign tumour arising from the vascular smooth muscle (tunica media) and presents commonly between third and fifth decades of life. Although there are sporadic reports about this tumour in the literature, none describes all the information in detail. This review is an attempt to collate all the facts in one concise article. Angioleiomyoma presents as a painful mass in approximately 60% of the cases. One of the distinct clinical feature noted is the increase in size of the swelling with physical activity of the involved part, especially in the hand. It should be considered in the differential diagnosis of painful nodular lesions of the extremity. Pre-operative diagnosis is difficult, but with a high index of suspicion and awareness, it is possible. The use of ultrasound and magnetic resonance imaging should be considered. It causes minimal morbidity and excision is usually curative. Histological examination using smooth muscle Actin stain portraits the smooth muscle bundles clearly.

“…Sardanelli and collaborators reported imaging a case of angioleiomyoma of the leg. 8 On color Doppler, the mass showed a tubular structure, which was a large feeder artery from the anterior tibial artery. Kunimatsu's group reported a case of a rapidly growing renal angioleiomyoma.…”

Giant Angioleiomyoma in Extremity: Report of Two Cases

Angioleiomyomas are smooth muscle tumors that occur most often in the extremities and are usually less than 2 cm in diameter. We present 2 case reports of giant angioleiomyoma. Case 1 was a 51-year-old woman with a 5-year history of a slowly growing mass 12×10 cm in diameter in the right posterior thigh. The tumor was larger than any previously reported. Case 2 was a 72-year-old man with an 8-year history of a slowly growing mass 6×6 cm in diameter in the left palm. The tumor was unique in that it grew to a giant size in the hand of the elderly patient. Magnetic resonance imaging of both cases conˆrmed the tumors' presence in the subcutis. T 1 -weighted images showed homogenous signal isointense to muscle. On T 2 -weighted images, areas of hyperintensity and hypointensity intermingled. Three-dimensional gadolinium-enhanced magnetic resonance angiography showed rapid initial enhancement followed by a gradual increase in enhancement, suggesting that the tumors were rich in vessels. Microscopic examination revealed numerous vascular channels embedded within a huge smooth muscle component.
