“…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 ]. AML is defined histologically as a benign pleomorphic mesenchymal tumor consisting of three histologic components: mature adipocytes, interlacing fascicles of smooth muscle cells, and abnormal tortuous convoluted thick-walled blood vessels without an elastic layer [ 3 6 7 8 9 ]. This classical triad is necessary for a definitive diagnosis [ 7 ].…”

This classical triad is necessary for a definitive diagnosis [ 7 ]. Depending on the frequency of occurring site, angiomyolipoma can be further categorized into renal AML and extrarenal AML-majority of AML's are renal AML (99.7% of all AMLs, 1% of all renal tumors [ 9 ]; 0.1%–0.3% incidence [ 10 11 ]) while very few comprise the extrarenal AML (0.3% of all AMLs) [ 12 ].…”

“…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 ].…”

“…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 ]. Moreover, in contrast to the renal AML which may be invasive and may recur [ 7 ], and display HMB-45 positivity in 95% of the patients [ 14 15 ], extrarenal AML has no recurrences and lack positivity to HMB-45 [ 16 ]. Demographically, sex and age separate these two entities: the renal AML has a female predominance, while the extrarenal AML has a male (male:female=12:2) predominance [ 4 12 14 19 ].…”

“…Among the extrarenal AMLs, the liver is by far the most common site [ 7 12 ] followed by the retroperitoneal region [ 20 ]. AMLs' occurring as hepatic lesions may present in association with TSC and may behave as an exception from the extrarenal AMLs [ 12 ].…”

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.
