背景:Leser-Trelat征是一种罕见的副肿瘤综合征,其主要特征是在身体不同部位出现多发性脂溢性角化病。这种综合征与多种胃肠道恶性肿瘤有关,尤其是胃和结肠腺癌。
方法:我们报告了一名70岁的男性,他到外科诊所就诊,抱怨过去2个月持续的下腹痛。疼痛与体重减轻和身体中多发性脂溢性角化病的逐渐出现有关。病人入院作进一步评估,CT扫描显示肠系膜中段有8.1×5.2cm肿块,实验室显示贫血和粪便潜血阳性。患者被安排进行剖腹探查术。在手术过程中,发现升结肠有大量肿块,并侵入相邻的乙状结肠。肿块被送至病理,并显示异物肉芽肿。除了手术,患者接受内窥镜检查以排除上消化道系统的恶性肿瘤,未发现肿块或病变。
结论:这是报告的首例病例,据我们所知,Leser-Trelat标志中的异物肉芽肿。异物肉芽肿与多种细胞信号有关,这可能是Leser-Trelat标志关联的来源。需要进一步评估以更好地了解Leser-Trelat标志与异物肉芽肿形成之间的关联。
BACKGROUND: Leser-Trelat sign is a rare paraneoplastic syndrome in which one main characteristic presented is an eruption of multiple seborrheic keratoses around different areas of the body. This syndrome has been associated with multiple gastrointestinal malignancies, especially adenocarcinoma of stomach and colon.
METHODS: We report a 70-year-old male who presented to the surgery clinic complaining of a persistent lower abdominal pain for the past 2 months. The pain was associated with weight loss and the gradual appearance of multiple seborrheic keratoses in his body. The patient was admitted to the hospital for further evaluation, a CT scan shows an 8.1 × 5.2 cm mass in the mid mesentery and laboratories shows anemia and positive fecal occult blood. The patient was scheduled for an exploratory laparotomy. During the surgery, a large mass was found arising from the ascending colon with invasion into the adjacent sigmoid colon. The mass was sent to pathology and shows a foreign body granuloma. In addition to the surgery, the patient undergoes an endoscopic evaluation to rule out a malignancy from the upper gastrointestinal system, no masses or lesions were found.
CONCLUSIONS: This is the first case reported, as far as our knowledge, of a foreign body granuloma in the association of Leser-Trelat sign. Foreign body granulomas are associated with multiple cellular signaling and this could be the source of the association of the Leser-Trelat sign. Further evaluation is needed to have a better understanding of the association between the Leser-Trelat sign and the formation of a foreign body granuloma.
