Pancreatic dermoid cysts are rare, benign, germ cell tumors and part of the differential diagnosis for cystic neoplasms of the pancreas.
A 35-year-old man presented with an incidentally discovered, 2 cm cystic pancreatic neoplasm of the pancreatic tail identified on CT scan. Endoscopic ultrasound (EUS) revealed a complex, honeycomb lesion. Fine needle aspiration (FNA) yielded a sample of whitish, necrotic material containing histiocytes, benign epithelial cells, and lymphocytes. After distal pancreatectomy and splenectomy was performed, histology revealed a cyst lined by stratified squamous epithelium with benign sebaceous units consistent with a pancreatic dermoid cysts.
Although axial imaging reliably detects cystic neoplasms of the pancreas, diagnostic criteria for rare lesions are lacking; therefore alternative modalities such as EUS/FNA can be utilized. This case report highlights the EUS and FNA findings associated with pancreatic dermoid cysts.
胰腺皮样囊肿是一种罕见的良性生殖细胞肿瘤，是胰腺囊性肿瘤鉴别诊断的一部分。
一名35岁男性在CT扫描时偶然发现胰腺尾部有一个2厘米的胰腺囊性肿瘤。内镜超声（EUS）显示为一个复杂的蜂窝状病变。细针穿刺抽吸（FNA）获取了一份含有组织细胞、良性上皮细胞和淋巴细胞的白色坏死物质样本。在进行了胰体尾切除术和脾切除术后，组织学检查显示囊肿内衬分层鳞状上皮，伴有良性皮脂腺单位，符合胰腺皮样囊肿。
尽管轴向成像能够可靠地检测出胰腺囊性肿瘤，但对于罕见病变缺乏诊断标准；因此，可以使用诸如EUS/FNA等替代方法。本病例报告突出了与胰腺皮样囊肿相关的EUS和FNA检查结果。
