Anosacral cutaneous amyloidosis: a study of 10 Chinese cases 总被引:1,自引:0,他引:1
BACKGROUND: Primary cutaneous amyloidoses are rare in Western countries, but are relatively common in Taiwan. Anosacral cutaneous amyloidosis is a rare type of primary cutaneous amyloidoses, first reported in Japanese patients. PATIENTS/METHODS: In the present study, we investigated the age of onset, sites of involvement, associated systemic diseases, and histopathological findings in 10 cases of anosacral cutaneous amyloidosis seen during the past 27 years. RESULTS: In previous reports the aetiology of anosacral cutaneous amyloidosis was thought to be a senile change, but half of our patients developed the disease before the age of 60 years. Based on our histopathological findings, apoptosis may be the initial event causing amyloid deposition, although the precise mechanism causing apoptosis needs further investigation. Three patients were found to have diabetes mellitus, but any relationship to anosacral cutaneous amyloidosis is unclear. CONCLUSIONS: No cases of this cutaneous disorder have been reported in the Western literature; there seems to be a racial difference accounting for the disease, although the precise factor is not clarified yet. The disease could easily be misdiagnosed as lichen simplex chronicus, postinflammatory hyperpigmentation or tinea cruris; therefore, a thorough history, a careful physical examination and a skin biopsy is needed to establish a firm diagnosis. 相似文献

原发性皮肤淀粉样变皮损常见于双侧胫前、背部及大腿,也可见于阴茎及面颈部,原发于头皮者少见,诊治具有一定的难度。现报道1例我科诊治原发于头皮的皮肤淀粉样变患者。给予0.1%维A酸外用头皮,治疗2个月,皮损变化不明显,瘙痒缓解,目前进一步随访中。 相似文献

目的:明确原发性皮肤淀粉样变患者发病相关因素。方法:对2018年3月至2019年1月我院52例原发性皮肤淀粉样(PCA)变患者及104名正常对照的资料进行分析。结果:多因素 Logistic回归分析显示原发性皮肤淀粉样变的发病因素中日光暴晒、搔抓、过敏为危险因素,OR值分别为3.044,9.254,4.653,P均<0.05。合并疾病中,湿疹、荨麻疹、过敏性鼻炎发病率在PCA患者与104名健康正常对照间比较,差异有统计学意义(P<0.05)。结论:日光暴晒、搔抓、过敏与原发性皮肤淀粉样变的发病有关,患者易合并湿疹、荨麻疹、过敏性鼻炎。 相似文献

We present long-term follow-up data on patients with nodular localized primary cutaneous amyloidosis (NLPCA) seen at the St John's Institute of Dermatology between 1968 and 1999. This is the largest clinical follow-up study of this type of amyloid to date. Based on these cases we estimate the rate of progression of NLPCA to systemic amyloidosis to be only 7%, much lower than the 50% rate currently quoted in the literature. 相似文献

Extensive nodular cutaneous amyloidosis: an unusual presentation 总被引:2,自引:0,他引:2
PR Criado†‡ CS Silva† C Vasconcellos†‡ NYS Valente† JB Maito† 《Journal of the European Academy of Dermatology and Venereology》2005,19(4):481-483
Amyloidosis is characterized by the deposition of a group of unrelated proteins leading to changes in tissue architecture and function. The nodular variant is the rarest form of the cutaneous amyloidoses. We report a patient with localized nodular amyloidosis without systemic amyloid involvement or paraproteinaemia after 6 years of follow-up. The unusual aspects of our case were a plaque presentation rather than nodular, and the disseminated pattern observed. 相似文献

目的:评价点阵CO2激光治疗原发性皮肤淀粉样变病的疗效。方法:采用点阵CO2激光治疗躯干及四肢原发性皮肤淀粉样变病,60~80 mJ/脉冲,每4周1次,共治疗3次。根据皮损大小、色素沉着及瘙痒对皮损进行评分。结果:共收集2017年12月至2018年12月10例患者,其中苔藓样淀粉样变性4例,斑状淀粉样变性6例。皮损大小、色素沉着及瘙痒由治疗前的36分,35分,38分下降至9分,12分,4分。三次治疗后的总有效率为100%,显效率为90%。未出现严重不良反应。结论:点阵CO2激光治疗原发性皮肤淀粉样变病安全有效。 相似文献
