    摘要:Acrodermatitis enteropathica (AcE) is a rare, autosomal recessive inherited disorder caused by mutation of the SLC39A4 gene coding for zinc transport protein (ZIP 4). The disease appears during childhood especially in breastfeeding or post-breastfeeding infant. Eczema herpeticum refers to a disseminated skin infection of herpes simplex virus that usually leads to vesicular eruptions commonly seen on a background of atopic dermatitis (AD). We describe an 11-year-old boy with periorificial erosions in periorbital, perinasal, perioral, perineal, and gluteal areas, accompanied with itchy vesicles, some covered with hemorrhagic crusts. A clinical diagnosis of AcE and eczema herpeticum with AD was supported by typical lesions and acute and chronic eczematous changes found mainly in the flexural aspects of extremities, which is diagnostic of AD. Laboratory findings showed anti HSV1 IgG (23.43) and high levels of IgE (478.9 IU/L). There was no multinucleated giant cell in the Tzanck test. Skin histology was compatible with AcE. Direct immunofluorescent examination showed no deposits of IgG, IgM, IgA, or complement. Complete resolution occurred within 2 weeks of acyclovir and oral zinc supplementation.

    摘要:Cheilitis granulomatosa (CG) is a rare idiopathic condition with painless lip swelling, characterized by non-necrotizing granulomatous inflammation in the absence of other identifiable causes such as Crohn's disease, sarcoidosis, foreign body reaction, or infection. CG may precede the presentation of Crohn's disease after long-term follow-up. Spontaneous remission of CG rarely occurs. To date, given the rarity of CG, there is no gold standard treatment. Recommended treatments are supported by small studies, case reports/series, and expert opinions. Glucocorticoids are the first-line therapy in the acute stages of the disease; however, recurrence commonly occurs. Previously, methotrexate (MTX) showed a beneficial effect on orofacial swelling in a case of CG accompanied by Crohn's disease. We present a patient with CG without Crohn's disease. He was treated with oral MTX in combination with intralesional corticosteroid injection on one side of the lip. The injected side showed improvement, while lip swelling on the noninjected area remained unchanged after 3 months of treatment. Therefore, CG is refractory to treatment with MTX from our experience. Further studies regarding the optimum dosage of MTX is needed.

    摘要:Dermatofibroma (DF) is a benign skin tumor that is well-known among dermatologists. We herein present a rare case of atrophic dermatofibroma presenting linear skin dimpling. The patient was a 25-year-old woman with a history of wild-type recessive dystrophic epidermolysis bullosa who had noticed linear concavity on her right lateral back 1 year before her initial presentation. Anetoderma, atrophic scar, localized morphea, or lupus erythematosus profundus were clinically suspected; however, a biopsy specimen from the dimpling lesion showed the fibrous and histiocytic tumor in the deep dermis. The spindle-to-rhomboid-shaped tumor cells were arranged with irregularly storiform pattern, and immunohistochemistry showed that the tumor cells were positive for factor XIIIa, and negative for CD34 and CD68. Elastica van Gieson staining showed an almost complete loss of elastic fibers, especially at the center of the lesion. The reduction of elastic fibers might have influenced the skin depression in this case. This rare case suggests the need to consider a subtype of DF in the differential diagnosis of dimpling skin lesions.

    摘要:Lymphangioma circumscriptum (LC) is a vascular malformation resulting from a developmental anomaly of the superficial lymphatic system of the skin. It is benign albeit uncommon. LC less frequently occurs on the penis. LC may be either congenital or acquired. Acquired cases appear to develop most frequently after interventions in the area or underlying pathologies. It is often mistaken for genital warts or molluscum contagiosum. We report here about a case of LC misdiagnosed with genital warts for 15 years. A biopsy eventually provided histopathological evidence. Various treatments are available for LC including surgical excision (which is the gold standard), CO2 laser ablation, cryotherapy, flash lamp pulsed dye laser, and electrocoagulation therapy. For our patient, one session of electrocoagulation was performed under local anesthesia. This treatment allowed an almost complete regression of the lesion without recurrence after 3 years of follow-up. Electrocoagulation may be an efficient treatment for LC in locations that may be surgically challenging such as penis.

    摘要:Kaposi's varicelliform eruption (KVE) is a disseminated cutaneous infection usually induced by herpesvirus type 1 or 2, vaccinia virus or Coxsackie A16 virus in a patient with an underlying dermatosis. Risk factors for KVE reported in the literature include erythroderma, systemic sepsis, therapy with immunosuppressants such as methotrexate and systemic steroids, and therapy with systemic retinoids. The occurrence of KVE in psoriasis is rare and it predominantly appears in patients affected by erythrodermic psoriasis during immunosuppressive treatment. We report our experience of a remarkable case of a patient affected by severe erythrodermic psoriasis and KVE that healed after antiviral treatment and after having received secukinumab. After 1 year, psoriasis was cleared and no recurrence of KVE had occurred.
  • 机译 Secukinumab治疗恶性斑块状银屑病
    摘要:Although available data are conflicting, psoriasis seems to be associated with an increased baseline risk of malignancy. In addition, some antipsoriatic systemic treatments have been associated with risk of malignancy. There is not enough data on the association of interleukin (IL)-17 and IL-23 inhibitors with malignancy rate, but there have been no cases reported so far. Secukinumab is a recombinant human monoclonal immunoglobulin G1/κ antibody that selectively targets IL-17A; it was demonstrated to be effective and safe for the treatment of moderate to severe psoriasis that may be appropriate in frail subjects, as patients previously experienced malignancy, as in the case reported.

    摘要:The introduction of biologic drugs for the treatment of moderate-to-severe psoriasis resulted in a significant improvement in patients' health. Moreover, treatment regimens in psoriatic patients should be tailored to meet specific needs based on disease severity, impact on quality of life, response to previous therapies and presence of comorbidities. Combination therapy of biologic agents with conventional systemic drugs has been proposed to optimize psoriasis treatment outcomes in unresponsive or partial responsive severe psoriatic patients. We report the case of a patient with a long-standing recalcitrant plaque psoriasis and psoriatic arthritis who was administered secukinumab combined with methotrexate. The patient had previously been treated with several topical and systemic therapies associated with loss of efficacy or adverse event occurrence. Approximately 24 weeks after starting the combined regimen, significant clearance of psoriasis and reduction of arthritis ensued, with no drug side effects.
  • 机译 Secukinumab治疗肥胖症患者的牛皮癣:Minireview和临床经验
    摘要:Psoriasis (PsO) has been associated with obesity, and its severity increases in obese subjects. The link between psoriatic condition and obesity is based on shared pathophysiological pathways where local and systemic inflammation promote each other; PsO is an inflammatory, immune-mediated disease, and the adipose tissue is the source of proinflammatory adipokines. Moreover, psoriatic arthritis (PsA) is an important comorbidity of PsO that reduces quality of life and makes difficult the patient's management. Treatment of obese subjects with moderate to severe PsO, even more if PsA is present, is challenging because of reduced efficacy of several systemic drugs and increased risk of adverse events. Secukinumab, a monoclonal antibody that selectively binds to and neutralizes interleukin 17A, shows efficacy on PsO in all body weight groups, even in the highest, whose response has a slight downward trend. Clinical features of two obese subjects, affected by PsO and PsA, successfully treated with secukinumab, are described.

    摘要:Upon the association of biologic treatments with reactivation of latent tuberculosis infection (LTBI), screening for Mycobacterium tuberculosisinfection and anti-tuberculosis chemoprophylaxis in positive patients are required prior to biologic drug administration. Nevertheless, the risk of infection relapses associated with biologic drugs seems to be different. No cases of reactivation of LTBI have been observed in secukinumab-treated subjects, in contrast with clinical reports on the risk associated with anti-tumor necrosis factor Α-based therapy. Twelve patients with moderate to severe plaque psoriasis eligible for systemic treatment and found to have LTBI received secukinumab without previous chemoprophylaxis initiation because of clinical contraindication for 10 cases and refusal by 2 patients. None of them had tuberculosis reactivation.

    摘要:Anogenital warts are caused by human papillomavirus types 6 and 11. They are rare in children, and treatment is difficult since conventional treatments are generally painful and require the patient to be anesthetized. Topical diphenylcyclopropenone (DPCP) is a contact immunotherapy used for treatments of recalcitrant warts and alopecia areata. We herein report 3 cases of anogenital warts in children successfully treated with topical DPCP. Our results suggest that topical DPCP may be a valuable option for the treatment of anogenital warts in children who have difficulty with painful destructive therapy.

    摘要:Acquired hemophilia A (AHA) is a rare autoimmune disorder with high morbidity and mortality. It results from the development of circulating autoantibodies against factor VIII. AHA can be seen in association with autoimmune vesiculobullous diseases, autoimmune diseases, malignancy, pregnancy, and medications. We report a 68-year-old Thai woman diagnosed and treated for bullous pemphigoid (BP) for 11 months who recently presented with a 3-day history of extensive hemorrhagic bullae and large intra-oral buccal hematoma. Laboratory investigations confirmed a prolonged activated partial thromboplastin time, a low factor VIII level, a high factor VIII inhibitor level, and elevated anti-BPAG180 and anti-BPAG230 titers, confirming the diagnosis of BP associated with AHA. Immunosuppressive therapy with systemic corticosteroids and cyclophosphamide combined with bypassing agents for bleeding control resulted in significant clinical improvement and subsequent negative antibody levels. There was no recurrence after a 7-month follow-up period. Due to life-threatening bleeding in severe AHA cases, early diagnosis and effective treatment in this condition are essential.
  • 机译 自体脂肪注入颞区引起的脱发:病例报告及文献复习
    摘要:Alopecia secondary to facial filler injections is a highly unusual sequela. Only 2 cases of hyaluronic acid-induced alopecia have been reported to date. Accumulating evidence suggests vascular compromise as its etiology, which can be accidental intravascular injection or external compression by overfilled materials. We hereby present, to the best of our knowledge, the first case of localized nonscarring and scarring alopecia secondary to autologous fat grafting and review the literature regarding filler-induced alopecia.

    摘要:Linear and annular lupus panniculitis of the scalp (LALPS) is a unique subset of lupus panniculitis, which results in non-scarring alopecia along the Blaschko line of the scalp in an otherwise healthy young patient. Numerous cases have been reported around the world, but data on their trichoscopic findings and correlations with the underlying pathology is sparse. We hereby present a case of 23-year-old male with LALPS and further describe his trichoscopic findings as well as their correlations with histopathological features.
  • 机译 大剂量全身类固醇疗法用于自身免疫性疾病逐渐减少期间的严重皮肤不良反应:对非HIV免疫重建炎症综合症的影响
    摘要:We present 2 cases of severe cutaneous adverse reactions (SCARs) during the tapering of corticosteroids, following several courses of high-dose pulse therapy for Vogt-Koyanagi-Harada disease. Their general symptoms and mucous membrane lesions, including those of the eye, were milder than those usually seen in Stevens-Johnson syndrome/toxic epidermal necrolysis. Based on their initial presentation, these cases were not initially identified as SCARs, but continued to progress over the course of a few days. The mechanism underlying the paradoxical response to steroid administration seen in these patients can be interpreted as immune reconstitution inflammatory syndrome in human immunodeficiency virus-negative patients.
  • 机译 一例东南亚男孩松动的毛发生长综合征
    摘要:Loose anagen hair syndrome is an uncommon hair disorder, particularly in non-Caucasian children. We report the case of a 13-year-old Thai boy who presented with a single patch of hair thinning on the frontal scalp with excessive shedding, and the hairs did not grow long. Microscopic examination showed naked anagen bulbs with ruffling of the cuticle, which is compatible with loose anagen hair syndrome. To our knowledge, there is no reported case in Southeast Asian children.
  • 机译 修复消色差激光纹身去除疤痕的原始方法
    摘要:Laser tattoo removal is expensive, painful, and time-consuming. Even with the use of the right laser equipment, it is often impossible to eliminate all pigments. Incomplete tattoo removal, one of the undesired effects of laser treatment, is widely disseminated in the media and accepted by most patients. However, few patients know that laser tattoo removal can cause permanent scars. Some patients who develop achromic scars can feel disappointed with the results of laser tattoo removal and take legal action against the physician responsible for the treatment. This paper describes our experience with a drug delivery treatment called MMP® (“Microinfusão de Medicamentos na Pele,” Portuguese acronym for “Microinfusion of Drugs in the Skin”) that repigments and improves the final esthetic results of achromic laser tattoo removal scars.
  • 机译 环状基底细胞癌自发消退:一例报告
    摘要:We herein present a case of annular basal cell carcinoma (BCC) with spontaneous regression on the right temporal region of a 56-year-old Japanese male. Histopathological examination revealed that the central section had no tumor cells. The sweat glands, follicles, and other cutaneous appendages were also absent. This pattern of spontaneous regression is quite uncommon, and understanding the histopathology may be important for future approaches to BCC.
  • 机译 Cogan综合征患者的指甲扁平苔藓:病例报告和讨论
    摘要:Cogan syndrome and lichen planus represent two autoimmune disorders. Cogan syndrome is a very rare type of ANCA-negative vasculitis affecting the eyes and vestibulocochlear system. It has been associated with other autoimmune disorders, none of them showing any lichenoid inflammation. We herein report the first case of a patient that suffered from Cogan disease and developed isolated lichen planus on all nails a few years after the first diagnosis. The combination of two autoimmune disorders is not unusual and raises the question of common immunogenetic pathomechanisms.
