The term "morphea" includes a wide spectrum of clinical entities, varying from localized plaques of only cosmetic importance to deep lesions resulting in considerable morbidity for the patient. In fact, although survival rates are no different from that of the general population, localized scleroderma may be associated with development of substantial disability, as occurs in deep morphea and in pediatric patients (disabling pansclerotic morphea of children). We report a case of morphea profunda affecting a young man with severe, rapidly progressive, widespread skin involvement and focus on the eventual systemic evolution of such cases. A 40-year-old man was admitted in 2002 for progressive subcutaneous indurations, preferentially involving the right side of the trunk. His health was altogether good, with the exception of a beginning chronic obstructive bronchopneumopathy. There was no family or personal history of dysmetabolic, cardiovascular, neoplastic, or cutaneous disease. Three years earlier, the patient had noted the appearance of two infiltrated, intensely red lesions on the right laterocervical and paraumbilical regions. These had been interpreted as subcutaneous lipomatosis on the basis of an ultrasound scan. The lesions had become progressively larger, while their surface had assumed a scleroatrophic appearance. Thereafter, other lesions had developed on his chest and lower limbs, mostly distributed on the right side of the body. Clinical examination revealed well demarcated, depressed sclerotic plaques with ivory-colored centers and erythematous borders ("lilac ring") localized on the neck, chest, and lower abdomen and limbs (Figure 1). They were bound to the deeper structures and arranged in a band-like linear distribution on the right side of the chest and abdomen where they extended horizontally for more than 10 cm in diameter. These lesions were totally asymptomatic. In addition, arborizing telangiectasias were evident on the neck and upper chest (Figure 2). Laboratory investigations provided normal range of erythrocyte sedimentation rat and C reactive protein levels and other inflammation markers. Antinuclear antibody, antidouble-strand DNA, antimitochondrial, anti-extractable antigens (anti-centromere, anti-Scl-70, anti-U1RNP), and anti-Borrelia burgdorferi antibodies were negative. Circulating immunocomplexes binding C1q were substantially increased. Oesophageal x-rays and lower limb electromyography were within normal limits; ventilatory function testing revealed a mild obstruction consistent with the beginning of chronic obstructive pulmonary disease. Although nailfold capillaroscopy documented nonspecific findings of connective tissue disease (mega-capillaries, segmentary dilatation and destruction), the laser-Doppler flussimetry revealed few signs of microcirculatory abnormalities, in absence of Raynaud's phenomenon. An abdominal wall ultrasonography, performed on a sclerotic plaque, documented thinning of the subcutaneous tissue, with increase of the fibrous component and lower fascia and muscle retraction. The biopsy specimen from the abdominal region included fascia and the subcutaneous tissue (previously obtained from the lower abdomen) with epidermal atrophy, a thickening and homogenization of collagen bundles in the deep dermis and hair reduction. A perivascular lympho-monocytic and plasmacellular infiltration with a dermo-epidermal distribution was present. Moreover, septal fibrosis with a perivascular lymphoplasmacellular inflammatory infiltrate was documented within the abdominal rectus muscle. The diagnosis of morphea profunda was made on the basis of clinical and histopathological findings. A therapeutic regimen based on amino benzoic potassium (Potaba; Glenwood, LLC, Glenwood, NJ), oral prednisone, and topical clobetasol was started. After several months of follow-up, the patient had obtained only moderate improvement of the clinical findings.
“硬斑病”一词涵盖了广泛的临床病症,从仅具有美容意义的局限性斑块到导致患者出现相当大发病率的深部病变不等。事实上,尽管硬斑病患者的生存率与普通人群无异,但局限性硬皮病可能会导致严重残疾,如深部硬斑病和儿科患者(儿童致残性泛发性硬斑病)的情况。我们报告一例深部硬斑病病例,患者为一名青年男性,皮肤出现严重、快速进展且广泛的受累情况,并关注此类病例最终的全身演变。一名40岁男性于2002年因进行性皮下硬结入院,硬结主要累及躯干右侧。除了刚开始出现的慢性阻塞性支气管肺炎外,他的整体健康状况良好。患者无代谢紊乱、心血管、肿瘤或皮肤疾病的家族史或个人史。三年前,患者注意到右颈外侧和脐旁区域出现了两个浸润性、颜色深红的病变。基于超声扫描,这些病变被诊断为皮下脂肪瘤。病变逐渐增大,同时其表面呈现出硬化萎缩的外观。此后,他的胸部和下肢又出现了其他病变,主要分布在身体右侧。临床检查发现,颈部、胸部、下腹部和四肢存在边界清晰、凹陷的硬化斑块,中心呈象牙色,边缘为红斑(“紫丁香环”)(图1)。这些斑块与深部结构相连,在胸部和腹部右侧呈带状线性分布,直径水平延伸超过10厘米。这些病变完全没有症状。此外,颈部和上胸部可见树枝状毛细血管扩张(图2)。实验室检查显示红细胞沉降率和C反应蛋白水平以及其他炎症标志物在正常范围内。抗核抗体、抗双链DNA、抗线粒体、抗可提取抗原(抗着丝点抗体、抗Scl - 70、抗U1RNP)和抗伯氏疏螺旋体抗体均为阴性。结合C1q的循环免疫复合物显著增加。食管X线检查和下肢肌电图检查结果正常;通气功能测试显示存在轻度阻塞,与慢性阻塞性肺疾病初期相符。尽管甲襞毛细血管镜检查记录了结缔组织病的非特异性表现(巨型毛细血管、节段性扩张和破坏),但激光多普勒血流仪检查显示在无雷诺现象时,微循环异常的迹象很少。对一个硬化斑块进行的腹壁超声检查显示皮下组织变薄,纤维成分增加,下腹膜和肌肉回缩。腹部区域的活检标本包括筋膜和皮下组织(先前取自下腹部),伴有表皮萎缩、真皮深层胶原束增厚和均质化以及毛发减少。存在血管周围淋巴细胞和浆细胞浸润,并呈真皮 - 表皮分布。此外,在腹直肌内记录到间隔纤维化,伴有血管周围淋巴细胞浆细胞性炎症浸润。根据临床和组织病理学检查结果诊断为深部硬斑病。开始采用基于对氨基苯甲酸钾(Potaba;Glenwood,LLC,新泽西州格伦伍德)、口服泼尼松和外用氯倍他索的治疗方案。经过数月的随访,患者的临床症状仅得到中度改善。
