Objective: SHR-1210 is a new and promising anti-PD-1 agent for solid tumors. During the phase I study of SHR-1210, we encountered a novel but prevalent immune-related dermatologic toxicity: reactive capillary hemangiomas(RCHs). Thus we tried to summarize the features of RCHs and estimate their relationship with tumor response.Methods: This prospective observational study systematically enrolled 98 patients with advanced solid tumors from April 27th,2016 to June 8th, 2017 in the context of the phase I clinical study of SHR-1210. This report focused on the skin toxicities. Patients underwent entire skin inspection every two weeks while taking medication. The clinical course of RCHs was recorded and their association with tumor response was estimated. The data cut-off date was November 15th, 2017.Results: After a median follow-up of 242(range, 29–567) days, RCHs were observed in 85.7%(84/98) of patients on cutaneous/mucosal surfaces; 84.5%(71/84) of the RCHs were evaluated as grade 1 adverse events. No grade 3 or 4 RCHs were observed. The time of onset of RCHs was dose dependent and shortest in the 400 mg-dose cohort(P < 0.001). Spontaneous and complete regression of RCHs was observed both during and after treatment. The objective response rate of tumors for patients with RCHs was 28.9%(24/83). However, no responders were observed among the patients without RCHs.Conclusions: RCHs were prevalent but manageable during treatment with SHR-1210. It might add to the expanding literature regarding immune-related dermatologic adverse events. 展开更多

Currently, there are two kinds of inhibitors: Anti-PD-1 antibodies and anti-PD-L1 antibodies. These inhibitors have shown significant implications in improving the outcomes of certain cancer types in recent years.However, along with its effectiveness, adverse events cannot be ignored. As an anti-PD-1 antibody, camrelizumab(SHR-1210) has some side effects in tumor immunotherapy. The most common adverse event is reactive capillary hemangioma. While it is widely reported to occur in the skin, gingival reactive capillary hemangioma is rarely reported.CASE SUMMARY A 54-year-old man complained of gingival overgrowth on the anterior aspect of the maxilla and mandible for more than 6 mo. He had been placed on SHR-1210 for lung cancer for 7 mo. A gingival mass extending from canine to canine was noted on the lingual surfaces of the mandible. Gingival enlargement was noted in the front teeth. A clinical diagnosis of gingival reactive capillary hemangioma and chronic periodontitis was made. The treatment involved a complex local treatment(repeated local applications of an antibiotic paste, scaling and root planning, and surgery). The excised tissue was sent for histopathological examination, which confirmed the diagnosis of capillary hemangioma. After the operation, most of the gingival enlargement was reduced. At the 2-mo follow-up,it was noted that the gingival overgrowth was immediately reduced after the replacement of the anti-PD-1 agent with an anti-PD-L1 agent.CONCLUSION As the prescription for SHR-1210 has increased considerably in recent years, the occurrence of its possible side effects, including gingival reactive capillary hemangioma, has increased. It is recommended that regular oral examinations be performed before and during the treatment of tumors with SHR-1210. 展开更多

BACKGROUND: Lobular capillary hemangioma (LCH) is a benign vascular tumor that is rare in adults and has never been reported in the liver. This vascular lesion usually presents on the skin or mucous membranes, and predominantly affects children. METHODS: LCH as a large asymptomatic hepatic mass was seen in a 35-year-old female. Imaging and pathologic characteristics of the mass are reviewed, and the relevant literature is also reviewed. RESULTS: A large vascular hepatic lesion was observed in an asymptomatic 35-year-old female. Pathologic examination after surgical resection revealed typical features of LCH. CONCLUSIONS: This is the first case of lobular capillary hemangioma seen as a liver lesion in an adult. Large vascular hepatic lesions pose significant difficulties in discerning benign from potentially malignant conditions. In this report we describe the pitfalls and radiological uncertainties with interpreting vascular lesions of the liver. (Hepatobiliary Pancreat Dis Int 2009; 8: 323-325) 展开更多

We report a case of capillary hemangiomsa that involved the entire middle ear space,external auditory canal(EAC) and tympanic antrum.Symptoms in the case included ear fullness,hearing loss,otalgia and otorrhea.The case was misdiagnosed as recurrent chronic otitis media with granulation preoperatively.A diagnosis of capillary hemangioma was established by postoperative histological examination.The management of capillary hemangioma of the middle ear and external auditory canal is discussed,with a review of the literature.Because of its variable and sometimes misleading clinical presentation,hemangioma can initially be misdiagnosed as other lesions.Therefore,a high index of suspicion is necessary for early and accurate diagnosis. 展开更多

It commonly affects the face, eyelids, lips and skin. Adult capillary hemangioma involving the nasal cavity is rare and may be misdiagnosed as polyps or another tumor. This case report illustrated a middle-age adult patient in Malaysia who presents with unilateral nasal obstruction and intermittent epistaxis who later confirmed capillary hemangioma involving the right nasal septum. Endoscopic surgery excision of the hemangioma was successfully performed. There were no known risk factors present in him. A treating doctor in the outpatient clinic seeing symptoms such as unilateral nasal obstruction must consider alternative diagnosis such as hemangioma besides usual diagnosis of polyps. 展开更多

Recently, the development of endoscopic procedures has increased the availability of minimally invasive treatments; however, there have been few case reports of duodenal hemangioma treated by endoscopic mucosal resection. The present report describes a case of duodenal hemangioma that showed various endoscopic changes over time and was treated by endoscopic mucosal resection. An 80-year-old woman presented with tarry stools and a loss of appetite. An examination of her blood revealed severe anemia, and her hemoglobin level was 4.2 g/dL. An emergency upper gastrointestinal endoscopy was performed. A red, protrusive, semipedunculated tumor (approximately 20 mm in diameter) with spontaneous bleeding on its surface was found in the superior duodenal angle. Given the semipedunculated appearance of the tumor, it was suspected to be an epithelial tumor with a differential diagnosis of hyperplastic polyp. The biopsy results suggested a telangiectatic hemangioma. Because this lesion was considered to be responsible for her anemia, endoscopic mucosal resection was performed for diagnostic and treatment purposes after informed consent was obtained. A histopathological examination of the resected specimen revealed dilated and proliferated capillary lumens of various sizes, which confirmed the final diagnosis of duodenal hemangioma. Neither anemia nor tumor recurrence has been observed since the endoscopic mucosal resection (approximately 1 year). Duodenal hemangiomas can be treated endoscopically provided that sufficient consideration is given to all of the possible treatment strategies. Interestingly, duodenal hemangiomas show morphological changes that are influenced by various factors, such as mechanical stimuli. 展开更多

BACKGROUND Hemangioma is a vascular benign tumour of endothelial origin.It appears commonly in the first decade of life with increases incidence in females.Hemangioma is not common to happen in the oral cavity and it is extremely rare to appear in the labial vestibule.CASE SUMMARY We present a case of an 11-year-old girl who complained of a painful,slowly growing mass which was consistent with the capillary hemangioma in the left mandibular vestibule.Vascular tumor such as hemangioma in the mandibular vestibule is extremely rare;hence,the clinical definitive diagnosis is very challenging.Therefore,radiographic imaging and histopathologic analysis are crucial to reach to the final diagnosis for proper management.CONCLUSION Comprehensive clinical evaluation,proper diagnostic imaging and microscopic analysis of the mass establish a precise diagnosis of the hemangioma for better management. 展开更多

目的:探讨细胞外基质成份在毛细血管瘤病理演变中的作用。方法:采用免疫组织化学方法,观察层粘蛋白(LM)单克隆抗体在不同分期毛细血管瘤组织中的表达变化。结果:增殖期表达阳性率明显高于退化期及退化完成期,有非常显著差异(... 目的:探讨细胞外基质成份在毛细血管瘤病理演变中的作用。方法:采用免疫组织化学方法,观察层粘蛋白(LM)单克隆抗体在不同分期毛细血管瘤组织中的表达变化。结果:增殖期表达阳性率明显高于退化期及退化完成期,有非常显著差异(P<0.01),但后两者间则无差异(P<0.05)。增殖期多呈强阳性连续线状表达,而退化期及退化完成期则为(弱)阳性断续状。结论:LM的过量表达或含量增多可能有利于新生血管形成及维持内皮细胞的增殖状态。 展开更多
