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.

“…The author has reported a subcutaneous NF representing compressed fascia using both highresolution ultrasonography (US) and magnetic resonance imaging (MRI) appearances [4] and a rare case of intradermal type showing the primarily in the dermis accompanied by the dilatation and proliferation of the vessels using high-resolution color Doppler ultrasound [5], it is known that high-resolution US can clearly represent the location of the dermis and subcutaneous, association of the fascia, and the presence of dilation and proliferation of the vessels. The author usually performs US studies for dermatologic fields with a high-resolution, broad-band (5MHz-18MHz) linear transducer and described several studies [4,5,[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29].…”

Even though nodular fasciitis (NF) is benign and self-limited nature, the presentations of clinical, ultrasonographic, and pathological features have been described as mimicking sarcoma. Erickson-Johnson et al. suggested that ubiquitin-specific protease 6 (USP6) transcriptional upregulation may be the driving force behind the high proliferative activity and growth of NF. When the lesion showed the proliferative findings of the margin on both ultrasonography (US) and pathology, accompanied by clinically rapid growth, self-limited and/or regress course, NF could be strongly suggested as previously described. In this article, the author reviews the current knowledge of NF as USP6-associated neoplasia and also describes the therapeutic strategy in NF. In addition to the presentations of clinical, ulrtrasonographic, and pathological appearances of NF, the evaluation of percentage of USP6 break-apart FISH signals reflecting lifetime and mitotic counts in NF may be a potential procedure for accurate diagnosis in particularly young NF. It is putative that the inhibition of USP6-related genes might be the potential therapeutic strategies for the extremely rare malignant nodular fasciitis.

“…Enhancement pattern was heterogeneous [35]. As it is also important to differentiate between ALM and giant cell tumor of the tendon sheath (GCTTS), the author previously mentioned the characteristic appearances of GCTTS on US and MRI [20,36]. It is suggested that US study shows hypoechoic nodule with vascularity and low signal intensity on T1 and T2 weighted MR images due to the hemosiderin were observed in GCTTS [20,37].…”

ALM is a rare tumor that arises from the tunica media of small arteries and veins [1]. ALM typically occurs in the cutaneous, subcutaneous tissue of the lower extremities in middle-aged women. Histological appearances show a proliferation of smooth muscle cells and vascular channels and the classification into three histological subtypes such as solid (or capillary), cavernous, and venous types has been defined [1]. The author has previously described the solid (or capillary) subtype of ALM as a painful and vascularized subcutaneous tumor, probably in close to the dermis [2] and indicated that all painful cutaneous and subcutaneous tumors including ALM used as the acronym "ENGLAND" or "LEND an EGG"[3], especially, angioleiomyoma, eccrine spiradenoma, schwannoma, and glomus tumor show vascularlized appearances on high-resolution color Doppler US [4]. Recently, US findings of ALM based on pathologic subtypes have been described [5] and Kang et al. [6] have reported ALM findings on US and MRI. In this article, the current knowledge of the characteristic vascular status of subtype of subcutaneous ALM on color and power Doppler US along with MRI appearances will be reviewed.
