In contrast, a weak immunohistochemical expression of KIT was demonstrated in a single case of a granulosa cell tumor [56], while no KIT expression was identified in a gastrointestinal leiomyosarcoma (n = 1), endometrial adenocarcinoma (n = 1), adrenal cortex carcinoma (n = 1), thyroid gland carcinoma (n = 1) and Non-Hodgkin’s lymphoma (n = 2). This evidence concerns the gene KIT and non-Hodgkin lymphoma.
