Suprarenal Symplastic Leiomyoma of the Inferior Vena Cava

Symplastic Leiomyoma in the Suprarenal Inferior Vena Cava

“…The symplastic leiomyoma with a mitotic index lower than 10 mf/10 is a smooth muscle tumor which is rarely reported in the medical literature (13, 14). Only one case of IVC involvement was reported (15). …”

“…As with other defined vascular leiomyomas, MRI shows signal intensity depending on the histopathological changes and tissue content. This rare variant can easily be confused with leiomyosarcoma (15). Examinations using MRI are quite valuable in the evaluation of extensions and in planning surgery.…”

Symplastic Leiomyoma of Inferior Venacava: Presenting as a Retroperitoneal Mass

“…11,12 Only one case of IVC involvement has been reported. 13 The various growth patterns of the lieomyoma variants mimic that of an aggressive tumou Pleomorphic tumor cells with distinct atypical nuclei and low mitotic rate are important characteristics Smplastic leiomyoma. The pleomorphic cells often have multinucleated or multilobated nucleus, can be present focally, multifocally or diffusely throughout the mass, and generate more than 25% of the tumor in most cases.…”

“…9,11 In this study, we attempted to present a rare histological variant of leiomyoma, the" Symplastic leiomyoma", with its rarer occurrence in inferior venacava. 13 Due to the presence of large atypical bizarre nuclei, one can be tempted to call the tumour as malignanat i.e. leiomyosarcoma, 13 which should be avoided by carefull search for absence of necrosis and a low/absent mitosis.…”
