Abstract:
UNASSIGNED: Granular cell tumors (GCTs) are uncommon soft tissue tumors, which are difficult to diagnose merely by clinical examination. Fine-needle aspiration cytology (FNAC), being an effective first-line investigation, plays a significant role in the preoperative diagnosis of GCT. However, the tumor can mimic certain other lesions; hence, a cytopathologist needs to be aware of its characteristic morphology. We report here a case of GCT, presented as a subcutaneous nodule in the first finger web. A differential diagnosis of lipoma/neurofibroma was made clinically. FNAC was done and showed characteristic features of granular cell tumor along with intranuclear inclusions and subsequently, it was confirmed on histopathology.
摘要:
■颗粒细胞瘤(GCT)是不常见的软组织肿瘤,仅仅通过临床检查很难诊断。细针穿刺细胞学(FNAC),作为有效的一线调查,对GCT的术前诊断具有重要意义。然而,肿瘤可以模仿某些其他病变;因此,细胞病理学家需要了解其独特的形态。我们在这里报告一例GCT,表现为第一指网的皮下结节。临床诊断为脂肪瘤/神经纤维瘤。FNAC完成并显示颗粒细胞瘤的特征性特征以及核内包涵体,在组织病理学上得到证实。
