Auricular angioleiomyoma: a case report

Abstract

Angioleiomyoma (vascular leiomyoma or angiomyoma) is a rare, benign smooth muscle tumor that originates in the tunica media of blood vessels. These tumors may be found anywhere in the body. They usually occur in the lower extremity. Auricular angioleiomyoma is very rare, and only a few cases have been reported. We describe here a 38-year-old male patient with angioleiomyoma on the left auricular helix.

Preauricular Angioleiomyoma

“…The tumors usually present as small, solitary, round, firm masses that are skin-colored and enclosed in a capsule 4,8,12). There was no specific clinical presentation of angioleiomyoma.…”

Two Cases of Angioleiomyoma of the Auricle

“…Typically, the inner layers of the smooth muscles of vessels are arranged in an orderly circumferential fashion, and the outer layers spin or swirl away from the vessel and merge with the less well-ordered peripheral muscle fibers [4] . It is difficult to classify the vessels in these tumors as veins or arteries.…”

“…There are several reports of auricular angioleiomyoma in literature [1][2][3][4][5][6] . The common clinical presentation of this tumor is a skin-colored, round, and firm solitary nodule that is smaller than 1.5 cm in most cases.…”

“…As this tumor does not have any specific clinical symptoms or diagnostic characteristics, it is not easy to suspect this tumor unless it is found in the predilection sites [5] . Several reports of angioleiomyoma in the auricle have been published in literature [1][2][3][4][5][6] . The authors present two cases of auricular angioleiomyoma along with a review of literature.…”

“…Most commonly, this tumor appears as a painful solitary lesion on a lower extremity. However, it is painless when it occurs in the head and neck region [1][2][3][4] . As this tumor does not have any specific clinical symptoms or diagnostic characteristics, it is not easy to suspect this tumor unless it is found in the predilection sites [5] .…”
