RESUMO

Blocking of the growth plate (GP) using plates with screws (tension band plating) is a modern method used to correct deformities and moderate leg length discrepancy in growing children. Determining the duration of temporary bilateral blocking without the occurrence of irreversible changes of GP is of paramount importance important. Methods: Two-month-old Californian breed male rabbits (n=30) were exposed to bilateral blocking of the distal GP of the right femur locking plates with screws for 3, 5, and 7 weeks. The fixators were removed after 5 and 7 weeks in 18 rabbits and 3 weeks after that, animals were sacri!ced. The contralateral limb was used as a control. Histological, histomorphometric, and X-ray analyses were performed. Results: During GP blocking, its height gradually decreased. This decreased was more pronounced after 7 weeks. Destructive changes progressed with an increase in the blocking duration. Three weeks after discontinuation of the bilateral blocking that lasted 5 weeks, the height of the GP signi!cantly increased 1.2 times on the lateral side and 1.9 times on the medial side (p<0.001) compared to the control. When blocking was discontinued after 7 weeks, the structure of the GP was partially restored after 3 weeks, the height of GP signi!cantly increased 1.2 times on the lateral side, and 1.07 times on the medial side (p<0.01) compared to the control. Conclusion: Restoration of the structuralfunctional features of the GP after the removal of the plates depends on the duration of temporary bilateral blocking, which must be taken into account in the clinical setting.

El bloqueo de la placa de crecimiento (PC) utilizando placas con tornillos (banda de tensión) es un método moderno utilizado para corregir deformidades y alteraciones moderadas en la longitud de las piernas en niños en crecimiento. Es de suma importancia determinar cuál debe ser la duración del bloqueo bilateral temporal sin que ocurran cambios irreversibles en la PC. Métodos: Conejos machos de raza californiana de dos meses de edad (n = 30) fueron expuestos al bloqueo bilateral de la PC distal colocando placas del fémur derecho con tornillos durante 3, 5 y 7 semanas. Los fijadores fueron retirados después de 5 y 7 semanas en 18 de los conejos, y 3 semanas después los animales fueron sacrificados. La extremidad contralateral se utilizó como control. Se realizaron análisis histológicos, histomorfométricos y de rayos X. Resultados: Durante el bloqueo de la PC, su altura disminuyó gradualmente. Esta disminución fue más pronunciada después de 7 semanas. Los cambios destructivos se incrementaron a medida aumentaba la duración del bloqueo. Tres semanas después de la interrupción del bloqueo bilateral que duró 5 semanas, la altura de la PC aumentó significativamente 1.2 veces en el lado lateral y 1.9 veces en el lado medial (p <0.001) en comparación con el control. Conclusión: La restauración de las características funcionales estructurales de la PC después de la extracción de las placas depende de la duración del bloqueo bilateral temporal, lo que debería tenerse en cuenta en el tratamiento clínico de estas alteraciones.

RESUMO

Abstract Eccrine porocarcinoma (EPC) is a rare malignant skin tumor. The dermoscopy of invasive EPC reveals focal presence of whitish-pink, structureless areas surrounded by pinkish-white halos. In an eccrine poroma (EP), such areas present diffuse distribution in the "frog- eggs" pattern. We reported an EPC in situ that presents a transitional dermoscopy pattern between EP and invasive EPC. We found a diffuse distribution; whitish-pink, structureless areas surrounded by pinkish-white halos; a central exulceration and a polymorphic vascular pattern.

RESUMO

El propósito del presente estudio fue conocer la distribución de los ramos motores del nervio fibular superficial (NFS) y de sus respectivas penetraciones en los músculos fibulares en relación al ápice de la cabeza de la fíbula, dividiendo el compartimiento lateral de la pierna en tres regiones a fin de hacer posible una visión más segura de sus correlaciones clínicas y quirúrgicas. A través de disección, se estudiaron 60 piernas pareadas de 30 cadáveres adultos, de ambos sexos, Brasileños, con edad promedio de 44,9 años, siendo 8 de sexo femenino y 22 del masculino. Después de la disección se registraron las distancias de los puntos de penetración de los ramos del NFS en los músculos fibular largo (mFL) y corto (mFC), localizándolos en los tercios proximal, medio o distal, según fuere el caso. Se observó que el mayor número de ramos penetraron en el mFL a nivel de la parte distal del tercio proximal de la pierna, mientras que en el mFC lo hicieron en las partes proximal y distal del tercio medio de la pierna. Los ramos motores para el mFL penetraban en el vientre muscular entre 48,06 y 141,56 mm, y los ramos para el mFC lo hicieron entre 163,34 y 209,67 mm del origen del nervio. No hubo diferencias estadísticamente significativas ni entre los lados derecho e izquierdo ni entre genéros. Independiente de las diferencias metodológicas entre los estudios disponibles, el detalle de la distribución nerviosa en este compartimiento, permitirá una mayor precisión en el momento de elegirse un área para colgajo de injerto autólogo y una menor chance de lesiones iatrogénicas durante cirugías de la región.


The purpose of the present study was to know the distribution of the motor branches of the superficial fibular nerve (SFN) and their respective motor points in the fibular muscles in relation to the apex of the head of the fibula, dividing the lateral compartment of the leg in three regions in order to make possible a safer view of your clinical and surgical correlations. Through dissection, 60 paired legs of 30 adult cadavers, of both sexes, Brazilians, with an average age of 44.9 years, 8 being female and 22 male, were studied. After the dissection, the distances of the motor points of the NFS branches in the fibularis longus (FLm) and brevis (FBm) muscles were recorded, locating them in the proximal, middle or distal thirds. It was observed that the largest number of branches penetrated the FLm at the level of the distal part of the proximal third of the leg, while in the FBm they did so in the proximal and distal parts of the middle third of the leg. The motor branches for the FLm penetrated into the muscular belly between 48.06 and 141.56 mm, and the branches for the FBm did between 163.34 and 209.67 mm of the origin of the nerve. There were no statistically significant differences between the right and left sides or between genres. Regardless of the methodological differences between the available studies, the detail of the nervous distribution in this compartment will allow a greater precision at the time of choosing an area for autologous graft flap and a lower chance of iatrogenic injuries during surgeries of the region.

RESUMO

Introdução: As perdas de substância no terço inferior da perna costumam exigir elaboradas estratégias cirúrgicas para sua reconstrução. Dentre as opções existentes, o uso do retalho sural reverso de pedículo fasciossubcutâneo ou adipofascial reverso, citado na literatura como interessante alternativa, é pouco relatado, se comparado às outras técnicas mais utilizadas. O objetivo deste estudo é apresentar o resultado do tratamento de uma lesão exposta do tendão de Aquiles, realizado com retalho sural reverso de pedículo fasciossubcutâneo, associado à enxertia de pele total no mesmo tempo cirúrgico, discutindo as alternativas técnicas e as vantagens do procedimento. Relato de caso: A.D., 28 anos, portador de lesão complexa em terço distal da perna, decorrente de evolução desfavorável de procedimento ortopédico de reconstrução do tendão de Aquiles rompido em acidente automobilístico, ocorrido há mais de 30 dias, foi submetido à reconstrução da ferida por meio do retalho sural reverso de pedículo fasciossubcutâneo. A evolução pós-operatória foi favorável, não havendo complicações ou intercorrências. Conclusão: A técnica relatada apresentou uma boa opção com resultado satisfatório para a cobertura de lesão de terço inferior da perna com exposição do tendão de Aquiles.


Introduction: Loss of substance in the lower third of the leg usually requires complex surgical procedures for tissue reconstruction. Among the existing options for tissue reconstruction, reverse sural flap of the fasciosubcutaneous pedicle or reverse adipofascial flap, described in the literature as a viable option, has been little studied compared with other techniques. The objectives of this study were to present the results of surgical treatment of a complex injury due to Achilles tendon rupture using the reverse sural flap of the fasciosubcutaneous pedicle concomitantly with total skin grafting and to discuss the advantages of the procedure as well as other surgical alternatives. Case report: A.D., a 28-year-old male patient, presented with a complex injury in the lower third of the leg because of a poor outcome of surgical repair of Achilles tendon rupture that had occurred during an automobile accident more than 30 days previously. The patient underwent injury reconstruction with the reverse sural flap of the fasciosubcutaneous pedicle. The postoperative result was favorable, without complications. Conclusion: The surgical technique described here is satisfactory for treating lesions in the lower third of the leg due to Achilles tendon rupture.

RESUMO

Abstract: Clear cell acanthoma is an uncommon type of benign epithelial tumor. Typically, it is a solitary lesion found on the lower limbs. It presents as a nodule or small plaque with slow and well-defined growth. Diagnosis used to be clinical and histopathological, but the advent of dermoscopy has led to an increase in diagnostic accuracy. We describe a case in which dermoscopy proved highly useful for diagnosis of the lesion.

RESUMO

A claudicação intermitente é uma queixa geralmente relacionada com oclusão arterial secundária a doença aterosclerótica. Entretanto, em pacientes jovens com queixa de claudicação, outras causas devem ser pesquisadas, como a síndrome do aprisionamento da artéria poplítea, síndrome compartimental crônica, compressões ósseas e arterites. Os autores relatam o caso de um paciente com claudicação intermitente devido à compressão extrínseca da artéria tibial anterior pela membrana interóssea, diagnosticada através de angiorressonância durante manobras de dorsiflexão do pé. A paciente foi tratada com sucesso através da liberação do fator compressivo, evoluindo com melhora dos sintomas.


Lower extremity intermittent claudication is usually related to atherosclerotic disease. The most common non-atherosclerotic causes are arterites, chronic compartmental syndrome, bone compression, and popliteal entrapment syndrome. The authors report a case of a patient with intermittent claudication related to anterior tibial artery entrapment caused by the interosseous membrane. Magnetic resonance angiography showed compression of the anterior tibial artery during dynamic maneuvers and the patient was managed by releasing the cause of compression, resulting in relief from claudication.

RESUMO

Abstract: Angiosarcoma is a rare and aggressive tumor with high rates of metastasis and relapse. It shows a particular predilection for the skin and superficial soft tissues. We report three distinct and typical cases of angiosarcoma that were diagnosed in a single dermatology clinic over the course of less than a year: i) Angiosarcoma in lower limb affected by chronic lymphedema, featuring Stewart-Treves syndrome; ii) a case of the most common type of angiosarcoma loated in the scalp and face of elderly man and; iii) a skin Angiosarcoma in previously irradiated breast. All lesions presented characteristic histopathological findings: irregular vascular proliferation that dissects the collagen bundles with atypical endothelial nuclei projection toward the lumen.

RESUMO

We present the case of a left medial gastrocnemius and plantar muscle agenesis in a 58-years old male cadaveric specimen from the Anatomy Laboratory at the Universidad Industrial de Santander (Bucaramanga-Colombia). These unusual muscle absences and associated functional alterations, enrich anatomical knowledge and become important by the time the affected individual may need a reconstructive procedure.

RESUMO

ABSTRACT Objective: to evaluate the efficacy of Bacterial Cellulose (BC) membrane dressings in the treatment of lower limb venous ulcers. Methods: we carried out a prospective, randomized, controlled study of 25 patients with chronic venous ulcer disease in the lower limbs from the Angiology and Vascular Surgery Service of the Federal University of Pernambuco Hospital and from the Salgado Polyclinic of the County Health Department, Caruaru, Pernambuco. We randomly assigned patients to two groups: control group, receiving dressings with triglyceride oil (11 patients) and experimental group, treated with BC membrane (14 patients). We followed the patients for a period of 120 days. Results: There was a reduction in the wound area in both groups. There were no infections or reactions to the product in any of the groups. Patients in the BC group showed decreased pain and earlier discontinuation of analgesic use. Conclusion: BC membrane can be used as a dressing for the treatment of varicose ulcers of the lower limbs.

RESUMO

Heart failure is characterized by the inability of the cardiovascular system to maintain oxygen (O2) delivery (i.e., muscle blood flow in non-hypoxemic patients) to meet O2 demands. The resulting increase in fractional O2 extraction can be non-invasively tracked by deoxygenated hemoglobin concentration (deoxi-Hb) as measured by near-infrared spectroscopy (NIRS). We aimed to establish a simplified approach to extract deoxi-Hb-based indices of impaired muscle O2 delivery during rapidly-incrementing exercise in heart failure. We continuously probed the right vastus lateralis muscle with continuous-wave NIRS during a ramp-incremental cardiopulmonary exercise test in 10 patients (left ventricular ejection fraction <35%) and 10 age-matched healthy males. Deoxi-Hb is reported as % of total response (onset to peak exercise) in relation to work rate. Patients showed lower maximum exercise capacity and O2 uptake-work rate than controls (P<0.05). The deoxi-Hb response profile as a function of work rate was S-shaped in all subjects, i.e., it presented three distinct phases. Increased muscle deoxygenation in patients compared to controls was demonstrated by: i) a steeper mid-exercise deoxi-Hb-work rate slope (2.2±1.3 vs 1.0±0.3% peak/W, respectively; P<0.05), and ii) late-exercise increase in deoxi-Hb, which contrasted with stable or decreasing deoxi-Hb in all controls. Steeper deoxi-Hb-work rate slope was associated with lower peak work rate in patients (r=-0.73; P=0.01). This simplified approach to deoxi-Hb interpretation might prove useful in clinical settings to quantify impairments in O2 delivery by NIRS during ramp-incremental exercise in individual heart failure patients.

RESUMO

Introducción: El síndrome compartimental de la pierna es una complicación grave, de baja incidencia y en muchos casos ocasionado por un traumatismo de alta energía. El síndrome compartimental es una situación en la cual el incremento de la presión dentro de un espacio cerrado, por encima de la presión de perfusión puede generar un daño irreversible en los tejidos. Una vez diagnosticado el síndrome compartimental, la realización de una fasciotomia es esencial para la recuperación de la perfusión de los tejidos y así evitar las complicaciones. Objetivos: Evaluar los reparos anatómicos de los compartimientos de la pierna para la correcta realización de las fasciotomias. Material y Método: En un primer tiempo se realizaron jornadas demostraron cadavérica. En un segundo tiempo clase teórica, practica en preparaciones cadavéricas frescas. En esta instancia práctica, el docente participa solo con el rol de supervisor. Se analizo el desempeño de 10 residentes de cirugía general en el Hospital Aeronáutico Central y en la III Cátedra de Anatomía de la Facultad de Medicina de la Universidad de Buenos Aires, en el período de Agosto 2016 -Junio de 2017. Se realizaron encuestas anónimas, comparando el conocimiento previo de la región y el posterior. Resultados: 20 encuestas fueron analizadas, en cada una de ellas se tomó en cuenta el contenido de las mismas dividiéndolas en preguntas de categorización y preguntas teóricas. Se analizaran cuantitativamente las respuestas teóricas. En la primera serie de encuestas, denominadas pretest, de los 10 (100%) encuestados, 2 (20 %) contestaron correctamente las 8 preguntas de la encuesta, 3 (30%) contestaron 6 preguntas, 4 (40 %) contestaron 5 preguntas, 1(10%) contestó correctamente sólo dos. En la segunda serie de encuestas, al final de la actividad práctica, denominada postest, se puede apreciar una gran mejoría ya que en ese momento, de los 10 (100%) encuestados, 5 (50 %) contestaron correctamente las 8 preguntas de la encuesta, 4 (40%) contestaron 6 preguntas, 1 (10 %) respondió 5 preguntas. Conclusión: El conocimiento anatómico de las diferentes regiones del cuerpo humano aplicado a la cirugía y al desarrollo de las diferentes patologías resulta vital en el proceso de formación de los cirujanos novatos. Ya que toma un rol fundamental en la toma de decisión. La enseñanza de la anatomía quirúrgica en los programas de formación ha sido y continúa siendo un desafío. La incorporación de diferentes estrategias de enseñanza desde recursos audiovisuales hasta simulación sobre modelos cadavéricos es una herramienta sumamente varios para el cumplimiento del objetivo principal, el cual es mejorar la calidad asistencial y la capacidad resolutiva en situaciones de emergencia.


Introduction: Compartmental leg syndrome is a serious complication, low incidence and in many cases caused by high energy trauma. The compartment syndrome is a situation in which the increase of the pressure within a closed space, above the perfusion pressure can generate irreversible tissue damage. Once the compartment syndrome has been diagnosed, the realization of a fasciotomy is essential for the recovery of perfusion of the tissues and thus avoid complications. Objectives: To evaluate the anatomical repairs of the compartments of the leg for the correct realization of the fasciotomies. Material and method: In a first time, days of cadaverous showed were performed. In a second time theoretical class was realized (with audiovisual resources) and practice (with the performance of the maneuver) by a qualified teacher where the surgical approaches of the leg were made in fresh cadaveric preparations. In this practical instance, the teacher participates only with the role of supervisor. We analyzed the performance of 10 residents of general surgery at the Hospital Aeronautico Central and the Tercera Catedra de Anatomia of the Universidad de Buenos Aires, during the period of August 2016-June 2017. Anonymous surveys were carried out, comparing prior knowledge of the region and the later. Results: 20 surveys were analyzed. In the first series of surveys, called pretest, of the 10 (100%) respondents, 2 (20%) answered answered correctly the 8 questions of the survey, 3 (30%) answered 6 questions, 4 (40%) answered 5 questions , 1 (10%) correctly answered only two. In the second series of surveys, at the end of the practical activity, called posttest, you can see a great improvement since at that time, of the 10 (100%) respondents, 5 (50%) answered correctly the 8 questions of the survey, 4 (40%) answered 6 questions, 1 (10%) answered 5 questions. Conclusions: The anatomical knowledge of the different regions of the human body applied to surgery and the development of different pathologies is vital in the training process of novice surgeons. Since it takes a fundamental role in the decision making. The teaching of surgical anatomy in training programs has been and continues to be a challenge. The incorporation of different teaching strategies from audiovisual resources to simulation on cadaveric models is a very different tool for the fulfillment of the main objective, which is to improve the quality of care and the resolutive capacity in emergency situations.

RESUMO

OBJECTIVES: This study compared radiofrequency ablation versus conventional surgery in patients who had not undergone previous treatment for bilateral great saphenous vein insufficiency, with each patient serving as his own control. METHOD: This was a randomized controlled trial that included 18 patients and was carried out between November 2013 and May 2015. Each of the lower limbs of each patient was randomly assigned to undergo either radiofrequency ablation or conventional surgery. Clinical features (hyperpigmentation, hematoma, aesthetics, pain, skin burn, nerve injury, and thrombophlebitis) were evaluated at one week, one month, and six months postoperatively. Hemodynamic assessments (presence of resection or occlusion of the great saphenous vein and recurrent reflux in the sapheno-femoral junction and in the great saphenous vein) were performed at one month, six months, and 12 months postoperatively. The independent observer (a physician not involved in the original operation), patient, and duplex ultrasonographer were not made aware of the treatment done in each case. Clinicaltrials.gov: NCT02588911. RESULTS: Among the clinical variables analyzed, only the aesthetic evaluation by the physicians was significant, with radiofrequency ablation being considered better than conventional surgery (average, 0.91 points higher: standard deviation: 0.31; 95% confidence interval: -1.51, -0.30; p=0.003). However, in our study, we observed primary success rates of 80% for radiofrequency ablation and 100% for conventional surgery. CONCLUSIONS: If the physician is not required to inform the patient as to the technique being performed, the patient will not be able to identify the technique based on the signs and symptoms. Our study revealed that both techniques led to high levels of patient satisfaction, but our results favor the choice of conventional surgery over radiofrequency ablation, as patients who underwent conventional surgery had better hemodynamic assessments.

RESUMO

Abstract: Rosai-Dorfman disease is a benign histiocytic proliferative disorder of unknown etiology. The disease mainly affects lymph node tissue, although it is rarely confined to the skin. Here, we describe a 53-year-old woman with purely cutaneous Rosai-Dorfman disease. The patient presented with a large pigmented plaque on her left leg, and sparse erythematous papules on her face and arms. A complete clinical response was achieved with thalidomide, followed by recurrence at the initial site one year later. The histological examination displayed the typical features of Rosai-Dorfman disease in the recent lesions but not in the older lesions. In the setting of no lymphadenopathy, the histopathological features of Rosai-Dorfman disease are commonly misinterpreted. Therefore, awareness of the histological aspects present at different stages, not always featuring the hallmark microscopic signs of Rosai-Dorfman disease, is particularly important for a correct diagnosis of this rare disorder.

RESUMO

OBJECTIVES: Anterior cruciate ligament injury leads to adaptive responses to maintain postural control. However, there is no consensus regarding whether leg dominance also affects postural control in athletes with anterior cruciate ligament injury. The purpose of this study was to evaluate dynamic and static postural control among athletes with and without anterior cruciate ligament injury to the dominant leg. METHODS: Twenty-eight athletes, twenty-one males and seven females aged 15-45 years, were allocated to one of two groups: the anterior cruciate ligament injury group (26±3 years) or the control group without anterior cruciate ligament injury (25±6.5 years). All subjects performed one legged stance tests under eyes open and eyes closed conditions and squat and kick movement tests using a postural control protocol (AccuSwayPlus force platform, Massachusetts). The center of pressure displacement and speed were measured by the force platform. In addition, the distance traveled on the single-leg hop test was assessed as an objective measure of function. RESULTS: Significantly greater mediolateral sway was found under the eyes closed condition (p=0.04) and during squat movement (p=0.01) in the anterior cruciate ligament injury group than in the control group. Analysis of the single-leg hop test results showed no difference between the groups (p=0.73). CONCLUSION: Athletes with anterior cruciate ligament injury had greater mediolateral displacement of the center of pressure toward the dominant leg under the eyes closed condition and during squat movement compared to control athletes.

RESUMO

ABSTRACT: Objective: It was to identify trends of traumatic and non-traumatic causes of lower limb amputations, as well as the role played by population aging, traffic violence increase, public health policy of diabetes control program and drivers anti-alcohol laws on these amputations. Method: Hospitalization data recorded in the discharge forms of 32 hospitals located in the region of Ribeirão Preto, Brazil, from 1985 to 2008 were analyzed. Result: A total of 3,274 lower-limb amputations were analyzed, of which 95.2% were related to non-traumatic causes, mainly infectious and ischemic complications of diabetes mellitus. Cancer (2.8%) and congenital (1.3%) causes were included in this group. Only 4.8% were related to traumatic causes. Traumatic amputation average rate was 1.5 amputations in 100,000 habitants with a slight tendency of increase in the last 5 years. Non-traumatic causes showed an average rate of 30.0 amputations for 100,000 habitants and remained relatively constant during the whole period. Non-traumatic were much more predominant in patients older than 60 years and traumatic amputations occurred more frequently in patients younger than 39 years. Conclusion: The overall rates of amputation and the rates of traumatic and non-traumatic amputations remained nearly constant during the study period. The impact of diabetes control policies and the introduction of traffic safety laws could not be identified on the amputation rates.


RESUMO: Objetivo: Identificar as tendências temporais de causas traumáticas e não traumáticas de amputações de membros inferiores, e os efeitos do envelhecimento da população, do aumento de violência no trânsito, da política de saúde pública do programa de controle de diabetes e das leis de controle do uso de álcool em motoristas sobre as taxas de amputações. Método: Foram analisados os dados das folhas de alta de pacientes submetidos a amputações de todos os 32 hospitais localizados na região de Ribeirão Preto, Brasil, de 1985 a 2008. Resultado: De 3.274 amputações de membros inferiores, 95,2% estavam relacionadas a causas não traumáticas, principalmente complicações do diabetes mellitus. Câncer (2,8%) e causas congênitas (1,3%) foram incluídos neste grupo. Apenas 4,8% estavam relacionados às causas traumáticas. A taxa média de amputação traumática foi de 1,5 amputações por 100.000 habitantes, com uma ligeira tendência de aumento nos últimos 5 anos. As causas não traumáticas mostraram uma taxa média de 30 amputações por 100.000 habitantes e mantiveram-se relativamente constantes durante todo o período. As causas não traumáticas foram predominantes em pacientes com mais de 60 anos, e as amputações traumáticas ocorreram mais frequentemente em pacientes com menos de 39 anos. Conclusão: A taxa total de amputações e as taxas de amputações traumáticas e não traumáticas permaneceram praticamente constantes durante o período de estudo. O impacto das políticas de controle do diabetes e da introdução de leis de repressão do uso de álcool no trânsito não pode ser identificado nas taxas de amputação.

RESUMO

Abstract Plexiform neurofibromas are benign tumors originating from peripheral nerve sheaths, generally associated with Neurofibromatosis Type 1 (NF1). They are diffuse, painful and sometimes locally invasive, generating cosmetic problems. This report discusses an adolescent patient who presented with an isolated, giant plexiform neurofibroma on her leg that was confused with a vascular lesion due to its clinical aspects. Once the diagnosis was confirmed by surgical biopsy, excision of the lesion was performed with improvement of the symptoms.

RESUMO

Abstract Sweet's syndrome is a neutrophilic dermatosis with worldwide distribution that has been associated with inflammatory autoimmune diseases, infections, malignancies, drugs, and pregnancy. The disease is idiopathic in up to 50% of patients. A 64-year-old woman, diagnosed with right limb cellulitis (4 days of evolution), was seen at our department, due to persistent cellulitis and progressive appearance of painful nodules and plaques in both shins and the right forearm (2 days of evolution). Taken together, clinical, laboratory and pathological data suggested the diagnosis of Sweet's syndrome, probably secondary to cellulitis of the right inferior limb. We suggest that cellulitis may be associated with Sweet's syndrome, a rare association in the literature.
