ABSTRACT

BACKGROUND: CCD presents as non-caseating granulomas within the skin at a site distant from the GI tract. CCD is a debilitating extraintestinal sequela of CD that can sometimes precede its GI manifestations. In the absence of GI symptoms, the histopathologic and clinical features of CCD can present as a variety of inflammatory skin conditions that can range from ruptured follicle-associated granulomas to cutaneous ulcerations. While a variety of therapeutic options for patients with CCD and concurrent luminal CD have been described in the literature, there is no standard treatment algorithm for the management of refractory CCD with limited or covert GI involvement. CASE REPORT: The authors discuss the case of a 33-year-old female who presented to the wound care clinic with multiple "knife-edged" cutaneous ulcerations involving the intertriginous spaces, found to be consistent with CCD. Her original cutaneous symptoms and diagnosis manifested with minimal GI involvement and responded to IVIG treatment. CONCLUSIONS: This case supports the inclusion of CCD in the differential diagnosis in patients with knife-edged granulomatous skin lesions in intertriginous locations. This clinical condition may present in the setting of no or limited GI symptoms. The management of CCD and a proposed treatment algorithm are also presented.

ABSTRACT

Calciphylaxis is a rare and devastating condition found almost exclusively in patients with end-stage renal disease. Nonuremic calciphylaxis, an even more rare diagnosis, occurs in patients with preserved kidney function. We present a fatal case of nonuremic calciphylaxis with delayed and unexpected diagnosis despite early biopsy and testing. The patient presented with a 2-month history of painful ulceration to the left leg. Early biopsy was negative for calciphylaxis. Laboratory tests were negative for renal disease and autoimmune disorders. There was elevated parathyroid hormone (96 pg/mL) 3 months after initial presentation and documented cobalamin deficiency. The patient went on to develop wounds to both legs and her thighs. A second biopsy of a left thigh wound by means of the dermatology service revealed calciphylaxis. The purpose of this case report is to raise awareness of calciphylaxis as a differential diagnosis for chronic necrotic skin ulcers, especially in patients with preserved renal function and those on warfarin therapy.

ABSTRACT

Cartilage hypoplasia syndrome is a primary immunodeficiency disease characterized by short stature, hypoplastic hair and a variable degree of immunodeficiency. Noninfectious cutaneous granulomas represent an uncommon yet well-recognized manifestation within the spectrum of primary immunodeficiency diseases. However, cutaneous granulomas as a manifestation of cartilage-hair hypoplasia syndrome, are extremely rare. We present a case of a middle-aged man with cartilage hypoplasia syndrome featuring cutaneous granulomas, manifesting as chronic, extensive and deep cutaneous ulcers. The patient was treated with anti-TNF-alpha adalimumab with partial improvement. Our case underscores the broad spectrum of clinical manifestations associated with cartilage hypoplasia syndrome and adds new evidence to the potential therapeutic efficacy of anti-TNF-alpha drugs in its treatment.

ABSTRACT

BACKGROUND: Marjolin ulcer is a specific type of squamous cell cancer that can benefit from the use of lymphoscintigraphy.The purpose of this study was to evaluate 3 different injection techniques for sentinel node biopsy in patients with Marjolin ulcer. METHODS: Forty-eight patients with Marjolin ulcer (27 male and 21 female) ranging in age from 24 to 85 years were included in our study. Intratumoral (IT), peritumoral (PT) and periscar (PS) tissue injections of radiotracer were done in 9, 10, and 29 patients respectively. Injections were done 2-4 h before surgery. Lymphoscintigraphy was done for mapping the lymphatic drainage. During surgery, lymphatic mapping and sentinel node biopsy was performed using a handheld gamma probe. After harvesting sentinel nodes, regional lymph node dissection was done. RESULT: Sentinel node detection rate was higher in the PS group as compared to the IT and PT groups (89.6% vs. 50% and 22.2%) respectively. False negative rate was 0%. Pathologically involved sentinel nodes were detected in 16% of the included patients of our study which led to management change. None of the patients with pathologically non-involved sentinel nodes developed regional lymph node recurrence. CONCLUSION: Lymphatic mapping and sentinel node biopsy is feasible in Marjolin ulcer with high detection rate and low false negative cases which by detection of regional lymph node involvement can potentially change the management of patients. Injection site may be an important factor influencing the success of the procedure and injection of the mapping material in the peri-scar normal skin proximal to the lesion is the best technique.

ABSTRACT

Antimelanoma differentiation-associated protein 5 positive dermatomyositis (MDA5 DM) is a rare subtype of idiopathic inflammatory myopathy. There are limited data available regarding the cutaneous manifestations of MDA5 DM in the African American population. We presented the case of a male patient in his early 20s who presented with debilitating cutaneous ulceration and myopathy. Workup revealed interstitial lung disease (ILD) and positive MDA5 serology consistent with MDA5 DM. He made a remarkable recovery in terms of myopathy and cutaneous ulcerations with a multipronged regimen of prednisone, intravenous immunoglobulin and mycophenolate mofetil. However, there was a progression of ILD on this regimen which warranted use of rituximab.

ABSTRACT

Las úlceras cutáneas son un serio problema de salud, el cual tiene repercusiones socioeconómicas y laborales muy importantes con una elevada tendencia a la cronicidad y recidiva, estimándose que hasta el 50% de ellas permanecerán activas entre 6 meses y un año. Objetivo: Estudio del papel de los medicamentos en la etiología de las úlceras cutáneas. Material y método: Estudio de todas las notificaciones espontáneas relativas a úlceras cutáneas que constan en la base de datos del Sistema Español de Farmacovigilancia de medicamentos de uso humano.Resultados: Se identificaron 292 notificaciones en las que constaban sospechas de reacción adversa a medicamentos (RAM) del tipo lesión ulcerosa relacionadas con el consumo de medicamentos. Estaban implicados 369 medicamentos que suponen 427 principios activos. Las úlceras fundamentalmente aparecían en mujeres con una media de edad de 56,6 años. Los medicamentos sospechosos más frecuentemente notificados fueron los iSGLT-2, vacunas frente al COVID-19, metotrexato, hidroxicarbamida, trimetropim-sulfametoxazol, foscarnet trisódico hexahidrato, ribavirina, docetaxel, acenocumarol e imiquimod y asociación de lidocaína Hcl-pentosano polisulfato sodio-triamcinolona acetónido. Discusión: Numerosos medicamentos tienen como reacción adversa la aparición de úlceras. No debería descartarse esta posibilidad ante la aparición de una lesión cutánea nueva tras la administración de un nuevo medicamento dado que el 25% de las RAM eran desconocidas en el momento de su notificación, como eran los casos de úlceras asociadas a los i-SGLT2 y a las vacunas contra el COVID al inicio de su comercialización; sin embargo, gracias al hecho de seguir notificando las sospechas de RAM, se crearon alertas sanitarias advirtiendo de este hecho y es por ello que aconsejamos seguir notificando cualquier sospecha de RAM a los sistemas regionales de farmacovigilancia.(AU)


Skin ulcers are a serious health problem with significant socioeconomic and labour repercussions and a high tendency to chronicity and recurrence; approximately, up to 50% remain active between six months to one year. Aim: To study the role of drugs in the aetiology of skin ulcers. Material and method: A comprehensive study of all spontaneous reports related to skin ulcers that appear in the Spanish Pharmacovigilance System of Medicines for Human Use database. Results: A total of 292 reports were identified containing suspected adverse drug reactions (ADRs) of ulcer lesion type. Three hundred sixty-nine medications with 427 active ingredients were identified. The ulcers appeared mainly in women with a mean age of 56.6 years. The most frequently reported suspected drugs were SGLT-2, vaccines against COVID-19, methotrexate, hydroxycarbamide, trimethoprim-sulfamethoxazole, foscarnet trisodium hexahydrate, ribavirin, docetaxel, acenocumarol and imiquimod, and the combination of lidocaine Hcl-pentosan polysulfate sodium-triamcinolone acetonide. Discussion: Numerous medications may cause ulcers as an adverse reaction. This possibility should not be ruled out when a new skin lesion appears after the administration of new drugs since 25% of the ADRs were unknown at the time of their notification, as were the cases of ulcers associated with i-SGLT2 and vaccines against COVID at the beginning of their commercialization. However, informative health alerts can be generated by continuously notifying suspected ADRs, so we strongly advise reporting any suspected ADRs to the regional pharmacovigilance system.(AU)

ABSTRACT

ABSTRACT: The comprehensive management of a patient with chronic graft-versus-host disease skin ulcers after hematopoietic stem cell transplantation is challenging. This report describes the case of a 53-year-old woman who presented with ulcers on her right leg 140 weeks after a bone marrow transplant. The patient received wound assessment and management based on the Triangle of Wound Assessment and Wound Bed Preparation 2021, respectively. Hydrogel and antibacterial protease dressings were applied along with systemic oral administration of moxifloxacin hydrochloride (two capsules, two times daily) and JiXueGanPian tablets (classic Chinese herbal formula; two capsules, two times daily), hospital-community-home continuous care, and patient-centered education. Finally, after 133 days of nursing, the patient's wound was completely healed without complications or other skin issues. The use of hydrogel combined with the antibacterial protease dressing was a promising technique for handling this type of wound, enhanced by multidisciplinary collaboration. Of course, providing patients with education that focuses on prevention is necessary.

ABSTRACT

OBJECTIVE: . Aim: The purpose of the study was to identify the features of apoptotic and proliferative processes in experimental Staphylococcus aureus-infected radiation skin ulcer under conditions of photodynamic therapy and the use of platelet-rich plasma. PATIENTS AND METHODS: Materials and Methods: An experimental study was conducted on 95 six-month-old male rats of the WAG population, which were divided into three groups. Group 1 included 25 animals that were simulated a radiation ulcer of the skin in the thigh area with subsequent application to its surface on the 7th day after irradiation with 0.2 ml of a suspension of the Staphylococcus aureus (ATCC 25923) reference strain (0.5 million microbial cells/cm2). Group 2 included 25 animals with Staphylococcus aureus-infected radiation skin ulcer, which were subjected to photodynamic therapy a day after infection. Group 3 included 45 animals with Staphylococcus aureus-infected radiation skin ulcers, which, 1 day after infection, received photodynamic therapy in the first half of the day, and in the second half of the day the periphery of the wound defect was injected with platelet-rich plasma. The material for the study was skin with underlying soft tissues from the area of radiation exposure. Histological, immunohistochemical, morphometric and statistical methods were used. RESULTS: Results: In cases of simultaneous use of photodynamic therapy and platelet-rich plasma, compared with photodynamic therapy alone, the processes ofapoptosis and proliferation were more balanced, active, with a shift in the proliferative-apoptotic ratio towards proliferation processes and met the needs of the regenerative process. From the 10th to the 22nd day of the experiment these processes increased, which indicated active healing processes, that, during survey microscopy on the 22nd day, were manifested by the complete filling of the wound cavity with granulation and connective tissues with the presence of an epithelial layer on the surface of the regenerate. From the 22nd to the 45th day of the experiment, a decrease in the rate of regeneration was recorded, as evidenced by a decrease in the intensity of apoptotic and proliferative processes. The intensity of the latter was sufficient, which led to the healing of Staphylococcus aureus-infected radiation skin ulcer on the 45th day with complete restoration of the original structure of the skin. CONCLUSION: Conclusions: Photodynamic therapy in combination with the use of platelet-rich plasma balancedly activates apoptotic and proliferative processes with a predominance of the latter in granulation and connective tissues filling the lumen of Staphylococcus aureus-infected radiation skin ulcer, which on the 45th day of the experiment leads to wound healing with complete restoration of the original structure of the skin.

ABSTRACT

BACKGROUND: Cutaneous melanoma is characterized by a high risk of metastasis to distant organs and a substantial mortality rate. For planning treatment and assessing outcomes, the Breslow micrometric measurement is critical. The tumor macroscopic dimension is not considered a prognostic parameter in cutaneous melanoma, although there are studies showing that tumor size is an independent prognostic factor for melanoma-specific survival. Therefore, this study aimed to evaluate the macroscopic dimension of melanoma and other known prognostic factors (i.e., Breslow index, mitoses, regression, and ulceration) as predictors of sentinel lymph node outcome and survival outcome. METHODS: We performed a retrospective cross-sectional study of 227 melanoma lesions subjected to sentinel lymph node biopsy at two Brazilian referral centers. RESULTS: On univariate analysis, there was a statistically significant correlation between the largest macroscopic tumor dimension and the sentinel lymph node result (P = 0.001); however, on multivariate analysis considering all evaluated parameters, there was no significant difference between the sentinel lymph node result and the tumor macroscopic dimension (P = 0.2689). Regarding melanoma-specific survival, the macroscopic dimension showed no significant correlation (P = 0.4632) in contrast to Breslow's dimension (P < 0.0001). CONCLUSION: The Breslow thickness was the only significant factor related to both the sentinel lymph node outcome and melanoma specific survival among the evaluated variables.

ABSTRACT

Chronic skin wounds represent a prominent etiological factor in the occurrence of non-traumatic foot amputations on a global scale and pose a substantial threat to the patient's well-being and mortality in the absence of effective treatment strategies. There exists a subset of patients that exhibit an insufficient response to different treatment options, comprising antibiotics, dressings, gauze bandages, debridement, rehabilitation, collagen patch, and vacuum-assisted closure. In this patient group, distinct treatment strategies emerge before surgery and amputation. Ozone therapy is one of them. Ozone exhibits a wide variety of effects such as antimicrobial, anti-inflammatory, antioxidant, and trophic. Its trophic effect is mediated by disinfection, stimulation of granulation tissue, acceleration of the angiogenesis process, and detoxification mechanisms. In this article, we presented the beneficial effect of ozone therapy in a case of chronic skin ulcer associated with livedoid vasculopathy. In this context, we aimed to discuss the role of ozone therapy in the management of chronic skin ulcers. Finally, we focused on ozone therapy as a promising method in inflammatory rheumatic diseases.

ABSTRACT

Digital ulcers (DU) are a common, severe vascular manifestation of systemic sclerosis (SSc) with few effective treatment options. Using data from the Australian Scleroderma Cohort Study (ASCS), we sought to evaluate the effect of calcium channel blockers (CCB) on the treatment and prevention of DU.Using data from 1953 participants, with a median of 4.34 years of follow-up, we used generalised estimating equations to evaluate the clinical characteristics associated with CCB use and ascertain the risk factors for the presence of DU at subsequent study visits. A time-dependent Cox-proportional hazard model was applied to evaluate the risk of future occurrence of DU with CCB use.Sixty-six percent of participants received CCB and patients with a history of DU were more likely to be prescribed a CCB (76.76% vs 53.70%, p < 0.01). CCB use was more frequent in patients with severe complications of DU including chronic DU (OR 1.47, p = 0.02), need for hospitalisation for iloprost (OR 1.30, p = 0.01) or antibiotics (OR 1.36, p = 0.04) and digital amputation (OR 1.48, p < 0.01). Use of CCB was more likely in patients who experienced DU at subsequent study visits (OR 1.32, p < 0.01) and was not associated with a decreased risk of the development of a first DU (HR 0.94, p = 0.65).CCB are frequently used in the management of SSc in the ASCS and their use is associated with severe peripheral vascular manifestations of SSc. However, our results suggest that CCB may not be effective in the healing or prevention of DU.

ABSTRACT

This report presents the case of an 11-year-old girl with juvenile dermatomyositis (JDM), anti-MDA5 antibodies and multiple skin ulcers. Treatment with traditional immunomodulators and tofacitinib resulted in healing of the skin ulcers and normalization of muscle enzyme markers. This case highlights the significance of recognizing the association between anti-MDA5 antibodies and cutaneous ulceration in JDM and supports the use of Janus kinase inhibitors as a management option.

ABSTRACT

At present, there are no standardized guidelines for determining patient eligibility for pyoderma gangrenosum (PG) clinical trials. Thus, we aim to determine which clinical features, histopathological features, or laboratory features should be included in active ulcerative PG clinical trial eligibility criteria for treatment-naïve patients and patients already treated with immunomodulating medications (treatment-exposed patients). This study employed 4 rounds of the Delphi technique. Electronic surveys were administered to 21 international board-certified dermatologists and plastic surgeon PG experts (June 2022-December 2022). Our results demonstrated that for a patient to be eligible for a PG trial, they must meet the following criteria: (i) presence of ulcer(s) with erythematous/violaceous undermining wound borders, (ii) presence of a painful or tender ulcer, (iii) history/presence of rapidly progressing disease, (iv) exclusion of infection and other causes of cutaneous ulceration, (v) biopsy for H&E staining, and (vi) a presence/history of pathergy. These criteria vary in importance for treatment-naïve versus treatment-exposed patients. Given the international cohort, we were unable to facilitate live discussions between rounds. This Delphi consensus study provides a set of specific, standardized eligibility criteria for PG clinical trials, thus addressing one of the main issues hampering progress toward Food and Drug Administration approval of medications for PG.

ABSTRACT

Marjolin's ulcer is described as malignant lesions developed in the injured skin, which can cause several kinds of malignancies. Our results showed that no HER2 but p53 was detected in Majorlin's ulcer samples. Meanwhile, by statistical analysis, we found that the positive rate of p53 in Majorlin's ulcer samples was associated with the pathological type of ulcer canceration and degree of tumor differentiation. The positive expression rate of vascular endothelial growth factor (VEGF) was 62.5% in poorly differentiated squamous cell carcinoma (SCC), 39.4% in moderately differentiated SCC, and 66.7% in well-differentiated SCC, respectively. Furthermore, some cases of Majorlin's ulcer with positive P53 were negative for VEGF, while some cases with positive VEGF were negative for P53. Image superposition showed that VEGF expression was absent or minimal in p53-positive cases. However, P53 was not expressed or rarely expressed in VEGF-positive cases. Our results of this study will suggest that P53 can be used as the mark of Marjolin's ulcer differentiation, and there may be some interaction between P53 and VEGF in Marjolin's ulcer. The regulation of microenvironment in the oncogenesis, progression, and differentiation of Marjolin's ulcer is complex and needs further study.

ABSTRACT

Purpose: The efficacy of adjunctive ambrisentan treatment in patients with systemic sclerosis (SSc) suffering from digital ulcers (DUs) was investigated.Material and methods: Patients (4 males, 7 females) diagnosed with SSc at our hospital between 2017 and 2022 were enrolled. Ten of them had diffuse SSc, while one had limited SSc. These patients received daily 5 mg doses of ambrisentan in addition to their regular SSc treatment for 16 weeks. Parameters including the total number and size of existing and new DUs, Visual Analog Score (VAS), frequency of Raynaud's phenomenon (RP) attacks, and any adverse effects were assessed.Results: At baseline, the median number and size of DUs was 3.0 (interquartile range (IQR): 2.0-4.0 cm) and 0.4 cm (IQR: 0.3-0.5 cm), respectively. Following the intervention, seven patients with a median of 2.0 DUs and a size of 0.35 cm (IQR: 0.15-0.45 cm) at baseline achieved complete healing. Significant improvements were also observed in other patients. VAS scores decreased from a baseline median of 5.0-0.0 (IQR: 0.0-1.0), and both the frequency and duration of RP attacks notably reduced.Conclusion: Adjunctive ambrisentan therapy proved effective in promoting DU healing and preventing new DUs in SSc patients.

ABSTRACT

INTRODUCTION: The healing of recurrent and refractory skin ulcers requires a long time, during which there is risk of infection, and hospital admission is occasionally required for surgical or daily conservative treatment. Therefore, the development of promising treatments that promote faster, uneventful healing is a must. Composed of cryoprecipitate and thrombin, fibrin glue has a history of surgical use for preventing bleeding and spinal fluid leakage. Moreover, in-house cryoprecipitates contain higher concentrations of coagulation factors and cytokines that may enhance wound healing than commercially available products. However, the efficacy of completely autologous fibrin glue (AFG) in tissue repair has not yet been fully demonstrated. PATIENT CONCERNS: This study aimed to evaluate the efficacy of AFG in the treatment of refractory skin ulcers in comparison with the conventional treatment. DIAGNOSIS: Two patients with skin ulcer on their lower extremities due to trauma or scleroderma who showed resistance to conventional treatment were included in the study. Both study participants were diagnosed with refractory skin ulcer and were ineligible for autologous skin transplantation. INTERVENTIONS: AFG was prepared following autologous blood donation using a Cryoseal® system. Subsequently, AFG was administered to 50% of the area of each ulcer and observed for 4 weeks in comparison with recombinant basic fibroblast growth factor with bucladesine sodium treatment that was administered to the rest of the ulcer. OUTCOMES: The skin ulcer after trauma in participant 1 showed better improvement in the AFG-treated area. Although AFG did not show superiority regarding the ulcer area of a patient with scleroderma, it guarded the continuous exudation from the edge of the swollen skin surrounding the ulcer. CONCLUSION: AFG showed effective and beneficial results for wound healing of refractory skin ulcer and prevented exudation without any severe adverse events.
