Cutaneous Angiomyolipoma-A Distinct Entity That Should Be Separated From Classic Angiomyolipoma: Complete Review of Existing Cases and Defining Fundamental Features

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.

[Serous micropapillary invasive carcinoma. Case report on both ovaries]

A subject that has been very controvertial in the last few years in the field of the surgical pathology has been the terminology and the concept of borderline serous tumor of ovary (TSL). Recently the term of micropapillary serous carcinoma was introduced (CSMP) to define a subtype of serous tumors that are characterized for a micropapillary grow pattern and that clinically associated with a more aggressive behavior than the classic TSL since they have an increased risk of invasion, recurrence and extraovarian tumor implantation. The majority of these cases are included within the serous bordering tumors of ovary, being the truly invasive tumors even more infrequent and with more aggressive clinical course. We reported the case of a 52 years old woman with bilateral invasive micropapillary serous carcinoma of ovary.
