■表皮样囊肿,很少是恶性的,是常见的皮肤囊肿。巨大的表皮样囊肿是直径>5cm的表皮样囊肿。
■这项研究的目的是描述临床表现,手术,一名69岁男子的术后病理组织,腹部巨大表皮样囊肿,部分囊壁鳞状上皮异型增生。患者经历的唯一症状是局部压痛。质量是坚硬而固定的,它的边界是明确的。通过进行超声引导下的穿刺活检,腹腔甲状腺肿穿刺液的细胞病理学结果显示右侧有异型增生的鳞状上皮细胞。右侧穿刺组织活检的免疫组织化学检查结果为鳞状细胞癌。2020-3-23,在全身麻醉下对右腹壁甲状腺肿进行无张力修复。患者在术后第五天出院。术后病理检查提示:(I)部分囊壁可见钙化高分化鳞状细胞癌;(II)横纹肌内侧纤维组织被高分化鳞状上皮覆盖;(III)部分囊壁破裂伴组织细胞增多和异物巨细胞反应,可见散见性角化病;(IV)鳞状上皮的某些区域为异质增殖癌,表现出高分化的浸润性鳞状细胞癌。
■作为外科医生,至关重要的是保持警惕,进行低阈值切除以及对标本进行彻底的组织学检查,以进行早期诊断和干预,这可以显著改善患者的预后。
UNASSIGNED: Epidermoid cysts, which are rarely malignant, are common skin cysts. A giant epidermoid cyst is an epidermoid cyst with a diameter of >5 cm.
UNASSIGNED: The purpose of this study was to describe the clinical presentation, surgery, and postoperative pathological tissue of a 69-year-old man who presented with a giant epidermoid cyst in the abdomen with heterogeneous hyperplasia of squamous epithelium in part of the cyst wall. The only symptom experienced by the patient was local tenderness. The mass was hard and fixed, and its boundary was clear. By performing ultrasound-guided puncture biopsy, the cytopathological results of the abdominal goitre puncture fluid showed that there were heterogeneous proliferating squamous epithelial cells on the right side. The immunohistochemical examination results of the puncture tissue biopsy on the right side showed a squamous cell carcinoma. On 2020-3-23, a tension-free repair of the right abdominal wall goitre was performed under general anaesthesia. The patient was discharged on the fifth postoperative day. The postoperative pathological examination indicated the following: (I) calcified highly differentiated squamous cell carcinoma was observed in part of the cystic wall; (II) the medial fibrous tissue of the striated muscle was covered with well-differentiated squamous epithelium; (III) part of the cyst wall was broken with histiocytosis and foreign body giant cell reaction, with visible scattered keratosis; and (IV) some areas of squamous epithelium were heterogeneously proliferating carcinoma, exhibiting well-differentiated invasive squamous cell carcinoma.
UNASSIGNED: As surgeons, it is crucial to remain vigilant and have a low threshold resection as well as thorough histological examination of specimens for early diagnosis and intervention, which can significantly improve patient outcomes.
