“…Demonstrated by the case findings, literature reports angioleiomyomas to consistently demonstrate spindle-shaped cells set in bundles with elongated cigar-shaped nuclei and surrounding vascular channels lined by regular endothelial cells [ 4 , 14 , 15 ]. Other reported histological findings include myxomatous or hyaline degeneration [ 4 , 14 , 15 ]. Current literature reports simple excision and primary closure to be the treatment of choice, with rare recurrence rates (approximately 0.36%) and minimal morbidity [ 3 ].…”

Angioleiomyomas are relatively rare benign smooth muscle soft tissue tumors which often occur on the extremities. They are rarely diagnosed preoperatively as clinical and radiological examination is often nonspecific and inconclusive. An 80-year-old male presented with a 10-year history of a progressively growing and symptomatic lesion on his right dorsal foot within the first intermetatarsal space. The preoperative diagnosis was suspected to be a neurogenic schwannoma arising from the deep peroneal nerve. Simple excision and histopathology confirmed a diagnosis of angioleiomyoma with nil recurrence or complications. The size of the angioleiomyoma was the second largest reported in literature to date. Angioleiomyomas are often misdiagnosed, and a degree of suspicion should be maintained in patients presenting with lower extremity growing soft tissue tumors.

Vascular lesions of the hand are common and are distinct from vascular lesions elsewhere because of the terminal vascular network in this region, the frequent hand exposure to trauma and microtrauma, and the superficial location of the lesions. Vascular lesions in the hand may be secondary to local pathology, a proximal source of emboli, or systemic diseases with vascular compromise. In most cases, ischaemic conditions are investigated with Doppler ultrasonography. However, computed tomography angiography (CTA) or dynamic contrast-enhanced magnetic resonance angiography (MRA) is often necessary for treatment planning. MR imaging is frequently performed with MRA to distinguish between vascular malformations, vascular tumours, and perivascular tumours. Some vascular tumours preferentially affect the hand, such as pyogenic granulomas or spindle cell haemangiomas associated with Maffucci syndrome. Glomus tumours are the most frequent perivascular tumours of the hand. The purpose of this article is to describe the state-of-the-art acquisition protocols and illustrate the different patterns of vascular lesions and perivascular tumours of the hand.

“…Kumar et al [27] mentioned that diffuse homogeneous enhancement of the mass lesion with a vessel converging on the superior pole of the mass lesion was shown on postcontrast fat suppressed T1-weighted images. Kang et al [28] described that slightly high signal intensity on T1-weighted image, a heterogeneous and high signal intensity on T2-weighted and STIR images, and heterogeneous enhancement on enhanced T1weighted image were shown. In addition, enhancing structures on one or both ends of the mass on MRI has been reported.…”

Angioleiomyoma (ALM) is a rare benign, vascular smooth muscle tumor originating from the tunica media of the vessel wall. It typically arises in the cutaneous, subcutaneous tissue of the lower extremities in middle-aged women. The author has previously described the solid subtype of ALM as a painful and vascularized subcutaneous tumor and indicated that all painful cutaneous and subcutaneous tumors used as the acronym "ENGLAND" or "LEND an EGG" show vascularized appearances on high-resolution color Doppler ultrasonography (US). Whereas ALMs of the fingers, toes, hands, and fee as acral type, namely acral calcified ALMs are rarely found. Kacerovska et al. mentioned that the lesion was pathologically composed of mature smooth muscle cells and vascular pattern accompanied with the prominent calcifications. In this article, the current knowledges of the acral calcified ALM have been reviewed in detail. Based on the evidence, acral calcified ALM pathologically shows the changes including calcification, sometimes extensive calcification hyalinization, and bleeding. Similar to the ordinary ALM, it is putative that acral calcified ALM also tends to represent painful and pathologically vascularized tumor. In addition to the characteristic manifestation of painful and vascularized tumor on color Doppler US, an acral calcified ALM should be considered as the differential diagnosis if the mass shows the calcification on high-resolution US in acral regions.
