BACKGROUND: @entity5123 ( @entity5123 ) is the most common @entity5 of the @entity3359 , while basal cell adenoma (BCA) is an uncommon @entity5 . Blood and lymphatic vessels are crucial for @entity5 metabolism. The aim of this study was to compare the blood and lymphatic vascular density and vascular and endothelial growth factor ( @entity7 ) expression in @entity5123 and BCA @entity5 . In addition, cell proliferation was evaluated in these @entity5 . METHODS: Blood and lymphatic vessel content, @entity7 expression, and cell proliferation were analyzed in 30 cases of @entity5123 and 13 cases of BCA by immu-nohistochemistry using antibodies for @entity2280 , CD105, D2-40, @entity7 , and @entity9965 . RESULTS: Regarding @entity2280 and CD105 expression, @entity5123 demonstrated a high vascularity and a low number of positive vessels, respectively. D2-40-positive lymphatic vessels were mainly located in the @entity5 capsules, with small intratumoral lymphatic vessels observed occasionally. @entity7 expression revealed a remarkably heterogeneous immunoreactivity, alternating from weak or negative to positive or intense. BCA presented significantly higher @entity2280 , @entity2280 , CD105, D2-40, and @entity7 expression compared to @entity5123 . No significant difference was found in cell proliferation between the @entity5 . CONCLUSION: Although @entity5123 and BCA are considered part of the same spectrum of differentiation, this study showed that the blood and lymphatic vascularization of these @entity5 is different.
