“…Angiomyolipoma (AML), also referred to as angiolipoleiomyoma (ALLM) [ 4 ], is classified as a hamartoma that belongs to a family of tumors arising from perivascular epithelioid cells (PEComas) [ 5 ]. Hamartoma is a focal malformation that resembles a benign neoplasm in that it is composed of tissue elements normally found in that tissue but grows in a disorderly fashion [ 3 ].…”

“…Once identified, renal AML is pathognomonic finding of TSC [ 12 ]. Renal AML can be identified in association not only with TSC (although most commonly) but also with other kidney diseases such as adult polycystic kidney disease, neurofibromatosis type 1, or von Hippel Lindau disease [ 4 ]. Among those who are diagnosed with TSC, 80% will have renal lesions [ 13 ].…”

“…Roughly one third (33%) of TSC patients will have renal AML [ 8 ]. Inversely, approximately 40% of patients with AML and TSC show stigmas or signs of adenoma sebaceum, ash-leaf macule, shagreen patches, or café au-lait macules [ 4 ]. Other signs of typical TSC include epilepsy (convulsive crises), mental retardation, oligophrenia, and renal AML [ 9 15 ].…”

“…The extrarenal AML has several synonyms that include mucocutaneous AML (MCAML) (proposed by Watanabe and Suzuki, 1999) [ 18 ], Cutaneous AML, and Cutaneous angiolipoleiomyoma (CALLM) [ 7 14 ]. Cutaneous AMLs are usually painless solitary lesions located in the acral area [ 4 ].…”

“…These different characteristics can be summarized as follows. First of all, renal AML has small to medium sized with thickened blood vessels with epithelioid components, while extrarenal AML has large blood vessels often without epithelioid components [ 4 ]. In addition, renal AML shows signs of TSC up to 30% while in the extrarenal AML, except for the liver, patients are not afflicted with TSC and have excellent prognosis [ 8 14 ].…”

Angiomyolipomas are hamartomatous lesions consisting of smooth muscle bundles, thick-walled blood vessels, and mature adipocytes. They are usually found in the kidneys of tuberous sclerosis patients and more rarely in other organs, such as the liver, the oral cavity, the sinonasal tract, the heart, the large intestines, the lungs, and the skin. Cutaneous angiomyolipoma has shown to be very rare and generally occurs at the ends of the digits, the elbows, the ears, and the nose. Herein, we report the first documented case of angiomyolipoma of the glabellar region.

BACKGROUND Angiomyolipomas (AMLs), belonging to the family of mesenchymal tumors, are considered benign lesions that occur mostly in the kidney or as a part of tuberous sclerosis. Epithelioid AML (EAML) is a rare type of AML that appears to have malignant potential. Extrarenal AMLs usually occur in the liver according to the retrieved literature reports. There have been only two previous reports of monofocal primary AML of the pancreas; however, no cases of primary monotypic EAML of the pancreas have been reported. CASE SUMMARY An asymptomatic 59-year-old woman incidentally revealed a tumor during abdominal ultrasound examination. Routine blood tests and physical examination were within normal limits. Abdominal ultrasound revealed a 1.9-cm hypoechogenic mass in the tail of the pancreas, clearly visualized by endoscopic ultrasound. However, contrast-enhanced abdominal computed tomography scans did not demonstrate the lesion. A subsequent gadolinium-enhanced magnetic resonance imaging scan showed that the lesion had some characteristic manifestations. The lesion was initially thought to be a neuroendocrine tumor (asymptomatic PanNET). After surgical resection, histopathology and immunohistochemistry confirmed the diagnosis of EAML. At the 6-mo follow-up, no recurrence, spread, or metastasis was identified on computed tomography or magnetic resonance imaging. CONCLUSION The preoperative diagnosis of pancreatic AML is extremely difficult. Imaging techniques are essential for providing valuable morphological features for differential diagnosis.

Cutaneous angiomyolipoma is a rare mesenchymal tumor that is demographically, clinically, and immunohistochemically distinct from its renal and extrarenal counterparts. We present a case of cutaneous angiomyolipoma in the right retroauricular area of a 35-year-old male patient and provide a broad systematic review of the literature and the largest compilation of cutaneous angiomyolipomas reported to date. According to the findings presented in this review, we conclude that cutaneous angiomyolipoma should be completely separated from renal and extrarenal angiomyolipomas and therefore be considered a distinct entity in the classification of skin tumors.
