“…3 With 23 previously reported cases, 39% (9/23) of which occurred in areas around the ear, the lesions are mostly solitary, asymptomatic, noninvasive, and nonrecurring. 4,5 The lesion is found mostly in adults, with patients' ages ranging from 16 to 77 years. 4 However, according to Ammanagi et al, 2 there was a recent case of angiomyolipoma found in a 3-year-old.…”

In this article, we will examine a case of cutaneous angiomyolipoma in the right nasal alar base area of a 36-year-old man. Generally, angiomyolipoma occurs in the kidney and, histologically, has features that are similar to cutaneous angiomyolipoma: smooth muscle cells, mature adipose cells, and a convoluted thick-walled blood vessel. Clinically, renal angiomyolipoma is related to tuberous sclerosis, but cutaneous angiomyolipomas occur very rarely, with a total of only 23 cases documented in the literature, with 39% (9/23) of those cases occurring in the ear or surrounding areas. In particular, the abundance of blood vessels inside a cutaneous angiomyolipoma produces good enhancement on computed tomographic image, making it easy for the tumor to be mistaken for a vascular tumor. In this particular case, we will report about a previously unheard case of cutaneous angiomyolipoma occurring in the nasal alar base that was mistaken for a vascular tumor.

“…Angiomyolipoma often arises from the kidney, but has also been described in extrarenal locations, such as the liver (1), uterus (2), and other infrequent sites (3)(4)(5). Angiomyolipomas arising from the skeleton are extremely rare and have been previously reported in the thoracic (6) and cervical spine (7), as well as the tibia (8).…”

Abstract. Angiomyolipoma is a benign mesenchymal tumor, most commonly arising from the kidney. With the exception of the liver, extrarenal angiomyolipoma is an infrequent entity that may be misdiagnosed as other tumors. Angiomyolipoma occurring in the skeleton is an extremely rare occurrence and often difficult to differentiate from other bone diseases. We herein present a case of angiomyolipoma in the rib of a 44-year-old male patient, a highly unusual location for this type of tumor. Angiomyolipoma of the skeleton usually exhibits an infiltrative tendency. Although this clinical entity is rare, angiomyolipoma should be considered in the differential diagnosis of skeletal lesions, particularly in patients presenting with imaging findings of fat within the lesions.
