“…10 Pain is the most common presenting symptom in patients with angioleiomyoma, reported in 58% of patients from a series by Hachisuga et al 7 The pain is thought to be related to local ischemia resulting from smooth muscle contraction. 4 There are 3 categories of vasculature patterns in an angioleiomyoma: type 1, several clustered linear vessels that converge to a single point; type 2, scattered distribution of irregular vessels; and type 3, vessels (1 or more) that are centrally located. 2 Vasculature is further classified as little (covering less than 20% of the mass), moderate (20%-50%), and rich (N 50%) vasculature.…”

Objective: The purpose of this case study is to describe the role of sonographic examination in the initial evaluation of an angioleiomyoma and to discuss the characteristic findings associated with this soft tissue mass. Clinical Features: A 52-year-old woman presented with a large, tender, erythematous mass on the anterolateral aspect of her right knee. Sonographic examination revealed a highly vascular mass within the subcutaneous tissues. Differential considerations included benign soft tissues masses such as angioleiomyoma and hemangioma. Intervention and Outcomes: Surgical consultation was recommended. Excisional biopsy was performed. Histopathological examination confirmed the diagnosis of angioleiomyoma. Conclusion: Although ultrasonographic findings of a superficial soft tissue mass may be nonspecific, when a highly vascular, well-defined, slow-growing mass is present, angioleiomyoma should be included in the differential diagnosis.

“…Yoo et al 11 suggested that the presence of tortuous vascular channels surrounded by smooth muscle bundles and areas of myxoid change could explain the heterogenicity of signal intensity of the tumor on T2-weighted images. Matsuyama et al 12 reported that some flow void is suggestive of vessels along and/or within the tumor and can help in the diagnosis of angioleiomyoma.…”

Angioleiomyoma represents a benign stromal tumor, which usually occurs in the subcutaneous tissue of the extremities. The angioleiomyoma in the finger is rare. We report 2 rare cases of an angioleiomyoma in finger. Case one, was a 72-year-old man with a mass on the radial side of distal phalanx of the left third finger. Case two, was a 70-year-old man with a mass on the ulnar side of interphalangeal joint of the left thumb. Both cases showed isointense to hypointense mass lesion on both T1 and T2-weighted images and were pathologically diagnosed with an angioleiomyoma. Heterogeneously isointense to hypointense on T2-weighted MR image showed two components: smooth muscle tissue punctuated with thick-walled vessles and/or hyalization on pathological finding. When much hyalization is included, it will not be enhanced on gadolinium-enhanced fat suppressed T1-weighted magnetic resonance (MR) image. Both T2-weighted and gadolinium-enhanced fat suppressed T1-weighted MR image findings should considered to predict tumor composition.

“…CT features consist of homogenous soft tissue mass with homogenous contrast enhancement. Regarding MRI, these tumors are most commonly isointense on T1-wighted images, heterogenous high signal intense on T2-weighted images, and have a homogenous strong enhancement [10].…”

Introduction: Laryngeal angioleiomyoma is a rare benign tumor of larynx with vascular origin. We report a case of laryngeal angioleiomyoma in a 52-year-old female. Case Presentation: A 52-year-old Caucasian female was referred to our institute with a chief compliant of severe midnight snoring. Her symptoms were progressive and began from two years ago. There was no history of hoarseness and laryngeal pain. The patient underwent a laryngoscopic examination and a large mass was seen on the left aryepiglotic fold. Surface of lesion was smooth and covered by laryngeal mucosa with no ulcer. There was a rapid enhancing mass on left aryepiglotic fold with bulging into the left piriformis sinus in contrast-enhanced computed tomography. The tumor was complicated by profuse bleeding after biopsy which was not controlled by conventional approaches. The patient was then administered a general anesthesia and the tumor was completely removed via laryngosurgery accompanied by left superior thyroid artery ligation. The specimen was histopathologically compatible with laryngeal angioleiomyoma. Conclusion: Angioleiomyoma of larynx is of benign nature and rarely recurs. However, it can be complicated by profuse bleeding on biopsy and contrast-medium imaging should be considered before surgical intervention to diagnose the tumor properly and prevent life-threatening complications.
