Gastrointestinal stromal tumors (GISTs) are the mesenchymal tumors of the gastrointestinal tract. Extra Gastrointestinal stromal tumors (EGISTs) are rare neoplasms that occur outside the gastrointestinal tract [1]. Miettinen et al. [2] described the first EGIST in 1999. EGIST accounts for 10% of all GISTs [3]. The main distinction between GIST and EGIST is the site of origin of the primary tumor, as GIST occurs throughout the GI tract, from the esophagus to the anus, whereas EGIST is a tumor without any connection with the intestinal wall and are reported in the retroperitoneum, mesentery, and omentum [4]. Hu et al. [5] reported a first case report of EGIST of larynx.We present a second case report of Extra-gastrointestinal stromal tumor of larynx a 47-year-old male reported to ENT Department Command Hospital Central Command Lucknow with complaints of Hoarseness. On examination found to have right vocal cord growth for which he underwent excision of right vocal cord growth. Histopathological examination showed typical of a spindle-cell GIST, showing strong immunoreactivity for CD 117, DOG1, Vimentin and CD 99. 6 months follow up post surgery with no recurrence.
胃肠道间质瘤(GISTs)是胃肠道的间叶性肿瘤。胃肠道外间质瘤(EGISTs)是发生在胃肠道外的罕见肿瘤[1]。1999年,米耶蒂宁等人[2]描述了首例EGIST。EGIST占所有GIST的10%[3]。GIST和EGIST的主要区别在于原发肿瘤的起源部位,因为GIST发生在整个胃肠道,从食管到肛门,而EGIST是一种与肠壁无任何关联的肿瘤,报道见于腹膜后、肠系膜和网膜[4]。胡等人[5]报道了首例喉EGIST病例报告。我们现报告第二例喉胃肠道外间质瘤病例,一名47岁男性因声音嘶哑主诉前往勒克瑙中央司令部指挥医院耳鼻喉科就诊。检查发现右侧声带肿物,遂行右侧声带肿物切除术。组织病理学检查显示为典型的梭形细胞GIST,对CD 117、DOG1、波形蛋白和CD 99呈强免疫反应性。术后6个月随访无复发。
