Abstract

INTRODUCTION

Pancreatic schwannomas are very rare neoplasm arising from Schwann cells that present in the nerve sheath. Schwannoma usually occur in the extremities but can also be found in the trunk, head and neck, retroperitoneum, mediastinum, pelvis and rectum.

PRESENTATION OF CASE

We briefly describe a 30-year-old female patient with upper abdominal pain and on examination by ultrasound and Computed tomography of abdomen revealed a solid tumor arising from body of the pancreas. A laparoscopic splenic vessel preserving distal pancreatectomy (kimura) was performed.

DISCUSSION

Approximately only 50 cases reported in the literature and none of these cases were diagnosed as schwannoma preoperatively. CT scan is often useful to establish pancreatic lesion which usually demonstrate hypodense lesion with encapsulation CONCLUSION: Although the incidence of pancreatic schwannoma is low, it must be considered as one possibility in the differential diagnosis of mass lesions in the pancreas and whenever possible especially in large tumors surgical resections should be considered due to increased chance of transformation to malignancy.

摘要

引言

胰腺神经鞘瘤是一种非常罕见的肿瘤,起源于神经鞘中的施万细胞。神经鞘瘤通常发生在四肢,但也可出现在躯干、头颈部、腹膜后、纵隔、骨盆和直肠。

病例介绍

我们简要描述一名30岁女性患者,有上腹部疼痛,经腹部超声和计算机断层扫描检查发现胰腺体部有一个实性肿瘤。实施了保留脾血管的腹腔镜远端胰腺切除术(木村术式)。

讨论

文献中报道的病例约仅50例,且这些病例术前均未诊断为神经鞘瘤。CT扫描通常有助于确定胰腺病变,其通常表现为有包膜的低密度病变。结论:尽管胰腺神经鞘瘤的发病率较低,但在胰腺肿块病变的鉴别诊断中必须将其视为一种可能情况,并且只要有可能,尤其是对于大肿瘤,由于恶变几率增加,应考虑手术切除。
