“…Members of the PEComa family that were recognized include AML, CCST, lymphangioleiomyomatosis (LAM), clear cell myomelanocytic tumor (CCMMT) of the falciform ligament/ ligamentum teres and a heterogeneous group of other "unusual clear cell tumors" at various anatomic sites [13]. The latter group includes tumors that have been reported under varying designations, such as abdominopelvic sarcoma of perivascular epithelioid cells [6], primary extrapulmonary sugar tumor (PEST) [38], clear cell myomelanocytic tumors of the skin [7] and thigh [15], and simply PEComa of various anatomic sites [1,9,12,19,24,27,28,31,40,41,45,46]; these, in addition to CCMMT of the falciform ligament [14] will henceforth be referred to as PEComa n ot o therwise s pecified (PEComa NOS). This descriptive designation, as used in this report, excludes the well-established entities LAM, CCST of the lungs and all variants of AML.…”
