{Reference Type}: Case Reports {Title}: Anastomosing hemangioma with extensive fatty stroma in the retroperitoneum. {Author}: Jayaram A;Manipadam MT;Jacob PM; {Journal}: Indian J Pathol Microbiol {Volume}: 61 {Issue}: 1 {Year}: Jan-Mar 2018 {Factor}: 0.773 {DOI}: 10.4103/IJPM.IJPM_259_16 {Abstract}: Anastomosing hemangiomas are a recently recognized benign vascular neoplasm, first described by Montgomery and Epstein in 2009. A few cases have been described in the genitourinary tract, especially in the renal hilum. These are fairly well-demarcated lesions with lobules of sinusoidal-like capillaries lined by hobnail endothelial cells containing eosinophilic hyaline globules in the cytoplasm. Extramedullary hematopoiesis has been described in a few cases, along with large feeding vessels. A predominant adipocytic component has been described in only one case.[9] We describe a case of a retroperitoneal anastomosing hemangioma occurring in an extrarenal site in a 53-year-old female, followed by a review of the current literature.
