ABSTRACT

Abstract Large defects in plantar surface secondary to acral melanoma excision can be difficult to repair with local flaps, and skin grafts in weight-bearing surfaces often suffer necrosis causing prolonged disability. Acellular dermal matrices represent an easy alternative to cover deep wounds or those with bone or tendon exposure. Despite their high cost and the requirement of two surgical procedures, this alternative may offer excellent functional and aesthetic results in acral defects.

ABSTRACT

Abstract Background: There are conflicting data regarding the prognostic value of the lymphatic basin drainage pattern in melanoma patients and the evidence is scant in the setting of negative sentinel lymph node biopsy. Objective: To investigate whether the pattern of lymphatic basin drainage influences the risk of nodal disease in patients with melanoma of the trunk and negative sentinel lymph node biopsy. Methods: A case series of patients with trunk melanoma and negative sentinel lymph node biopsy was retrospectively evaluated. Clinicopathological features, the pattern of lymphatic drainage and nodal, metastatic, and overall recurrence-free survival were reviewed. Results: Of the 135 patients included, multiple lymphatic basin drainage was identified in 61 (45.2%). Ten of the 74 (13.5%) patients with single drainage developed nodal recurrence, compared with 2 of the 61 (3.6%) patients with multiple drainages (p = 0.04). Nodal recurrence-free survival was significantly longer in the group with multiple drainages than in the group with single drainage (175.6 vs. 138.7 months; p = 0.04). In multivariate analysis, single drainage was associated with a higher risk of nodal recurrence (HR = 4.54; p = 0.05). No significant differences in metastatic and overall recurrence-free survival were found between groups. Study limitations: Retrospective analysis, single-center study, small sample, detailed histopathologic information not always present. Conclusions: In patients with trunk melanoma and negative sentinel lymph node biopsy, multiple lymphatic basin drainage may be an independent risk factor for nodal disease recurrence. This factor may help to identify patients with negative sentinel lymph node biopsy with a higher risk of nodal recurrence.

ABSTRACT

Contexto: O fibrohistiocitoma maligno é um sarcoma de tecidos moles muito agressivo, com rara apresentação limitada à pele e tecido subcutâneo em face. O diagnóstico é anatomopatológico com auxílio da imuno-histoquímica. Descrição do caso: Este artigo relata o caso de um paciente com diagnóstico de fibrohistiocitoma maligno restrito à face com boa resposta terapêutica após exérese cirúrgica. Discussão: Tendo em vista a raridade dessa afecção, dificuldade diagnóstica devido ao quadro inespecífico e com rápida evolução, é importante lembrar desse possível diagnóstico e atuar precocemente. Conclusões: O diagnóstico precoce interfere de forma significativa na evolução do quadro, sendo necessária a manutenção do acompanhamento oncológico e dermatológico com o intuito de detectar precocemente recidivas locais e metástases a distância.

ABSTRACT

Abstract Background: The ear is a region that has a high prevalence of cutaneous carcinomas and several guidelines indicate Mohs micrographic surgery as the first-choice treatment in such cases. Although the technique allows maximum preservation of healthy tissue, many auricular surgical wounds constitute a challenge due to the peculiar local anatomy, with evident curves and reliefs. Auricular reconstruction should prioritize function before aesthetics, but without leaving the latter aside, since postoperative distortions can have a significant psychological impact. Objective: To describe the authors' experience in auricular reconstruction after Mohs surgery and to evaluate the most frequently used repair methods. Methods: Retrospective study of consecutive cases submitted to Mohs surgery and auricular reconstruction, over a period of 3 years. Results: One hundred and one cases were included and the most common repair method was primary closure (n = 35), followed by full-thickness skin graft (n = 30) and flaps (n = 24). In thirty cases, reconstruction methods were associated. Seven patients had complications (partial graft necrosis, postoperative bleeding or infection). Study limitations: Retrospective design and the absence of long-term follow-up of some cases. Conclusions: The dermatologic surgeon should be familiarized with different options for auricular reconstruction. Primary closure and skin grafts were the most frequently used repair methods.

ABSTRACT

Abstract Melanoma in childhood is rare and its diagnosis is more difficult than in adults, as it often presents histologic features overlapping with the Spitz nevus. The authors report the case of a 17-year old boy who was first diagnosed with Spitz nevus, however, the final diagnosis made after the excision of the tumor arising in the scar was changed to melanoma. The case in this present study emphasizes the importance of the differential diagnosis of skin tumors in young patients.

ABSTRACT

Abstract Mohs micrographic surgery is a specialized form of skin cancer surgery that has the highest cure rates for several cutaneous malignancies. Certain skin cancers can have small extensions or "roots" that may be missed if an excised tumor is serially cross-sectioned in a "bread-loaf" fashion, commonly performed on excision specimens. The method of Mohs micrographic surgery is unique in that the dermatologist (Mohs surgeon) acts as both surgeon and pathologist, from the preoperative considerations until the reconstruction. Since Dr. Mohs's initial work in the 1930s, the practice of Mohs micrographic surgery has become increasingly widespread among the dermatologic surgery community worldwide and is considered the treatment of choice for many common and uncommon cutaneous neoplasms. Mohs micrographic surgery spares the maximal amount of normal tissue and is a safe procedure with very few complications, most of them managed by Mohs surgeons in their offices. Mohs micrographic surgery is the standard of care for high risks basal cell carcinomas and cutaneous squamous cell carcinoma and is commonly and increasingly used for melanoma and other rare tumors with superior cure rates. This review better familiarizes the dermatologists with the technique, explains the difference between Mohs micrographic surgery and wide local excision, and discusses its main indications.

ABSTRACT

Abstract External ear melanoma is rare, and early diagnosis and treatment are paramount for the patient's survival. Four clinical cases are reported, emphasizing the importance of the routine clinical examination of the ears in the dermatological consultation. The study included male and female patients, aged 60 to 81 years old, with melanocytic lesions in the outer ear, evaluated with detailed physical and dermoscopic examination, leading to the identification of lesions suggestive of melanoma. The cases were treated surgically with excision of the lesion, and the diagnoses were confirmed by histopathological study. The therapeutic approach was instituted early as most cases were diagnosed at an early stage, which directly impacted global survival.

ABSTRACT

Abstract Background: Non-melanoma skin cancer is the most common type of malignancy in the Western world, and surgical excision is the preferred approach. The approach adopted in the face of incomplete excisions of basal cell carcinoma is still controversial. Objectives: To compare the number of tumor recurrences after treatment for incompletely excised basal cell carcinoma. Methods: Selection and statistical analysis of medical records of patients who had compromised margins after excision of basal cell carcinoma in a tertiary hospital from 2008 to 2013. Results: A total of 120 medical records were analyzed; the mean age was 69.6 years, and 50% of the patients were female. The most prevalent histological type was nodular; the mean size was 1.1 cm, and the tumor location with the highest incidence was the nose. The lateral margin was the most frequently positive. Clinical follow-up was more widely adopted; only 40 patients underwent a second surgery. The total number of patients who had tumor recurrence was 34 (28.3%). Only the malar location significantly influenced the incidence of recurrence (p = 0.02). The mean follow-up time was 29.54 months, with no significant difference between the follow-ups, although 32.9% of the patients followed-up clinically showed recurrence, against only 20% of those who underwent a second surgery. Study limitations: Mean follow-up time of less than five years and sample size. Conclusions: The presence of compromised margins does not necessarily imply recurrence. Location, tumor size, histological subtype, previous epithelial tumors, and clinical conditions of the patient must be considered when choosing the best treatment option.

ABSTRACT

Abstract A 71 year-old male with a history of multiple excisions of an initial Clark's level V melanoma of the breast followed by combined radiation and interferon treatment, as well as a recurrence, 3 years later, of a BRAF-positive tumor of the shoulder, with subsequent therapy with dabrafenib and trametinib, presented again with progressive intracardiac masses causing significant right ventricular outflow obstruction. Additionally, the patient complained of dyspnea and fatigue on exertion, thus he was scheduled for surgical resection.

ABSTRACT

Abstract Background: Mohs micrographic surgery is worldwide used for treating skin cancers. After obtaining tumor-free margins, choosing the most appropriate type of closure can be challenging. Objectives: Our aim was to associate type of surgical reconstructions after Mohs micrographic surgery with the characteristics of the tumors as histological subtype, anatomical localization and especially number of surgical stages to achieve complete excision of the tumour. Methods: Transversal, retrospective analyses of medical records. Compilation of data such as gender, age, tumor location, histological subtype, number of stages to achieve clear margins and type of repair used. Results: A total of 975 of facial and extra-facial cases were analyzed. Linear closure was the most common repair by far (39%) and was associated with the smallest number of Mohs micrographic surgery stages. This type of closure was also more common in most histological subtypes and anatomical locations studied. Using Poisson regression model, nose defects presented 39% higher frequency of other closure types than the frequency of primary repairs, when compared to defects in other anatomic sites (p< 0.05). Tumors with two or more stages had a 28.6% higher frequency of other closure types than those operated in a single stage (p< 0.05). Study limitations: Retrospective study with limitations in obtaining information from medical records. The choice of closure type can be a personal choice. Conclusions: Primary closure should not be forgotten especially in surgical defects with fewer stages and in non-aggressive histological subtypes in main anatomic sites where Mohs micrographic surgery is performed.

ABSTRACT

Abstract Background: The treatment of basal cell carcinoma depends on its histological subtype. Therefore, a biopsy should be performed before definitive treatment. However, as the biopsy is only a sample of the tumor, it does not always shows every histological subtype present in the neoplasm. Few studies have compared the histological findings of biopsies with the findings of Mohs micrographic surgery. By evaluating the totality of the peripheral margins, in addition to sampling large tumor areas, this technique provides a more representative amount of tissue than preoperative biopsy. Objectives: a) Determine the agreement between the histological subtype of basal cell carcinoma from punch biopsy and the findings of Mohs surgery; b) To assess, among the discordant cases, the prevalence of non-aggressive tumors in the preoperative biopsy that were reclassified as aggressive by Mohs surgery. Methods: Retrospective analysis of 79 cases of basal cell carcinomas submitted to punch biopsy and subsequent Mohs surgery. Results: The agreement between the classification of the subtypes in the biopsy and in Mohs surgery was 40.5%. Punch biopsy was able to predict the most aggressive basal cell carcinoma growth pattern in 83% of cases. Study limitations: Retrospective nature, sample size, and biopsies performed by different professionals. Conclusions: The agreement between the histopathological subtypes of basal cell carcinoma as seen in preoperative biopsy and Mohs surgery was low. However, preoperative biopsy presented good accuracy (83%) in detecting aggressive histopathological subtypes.

ABSTRACT

Abstract Background: High-risk basal cell carcinoma involves a significant rate of basal cell carcinoma that requires Mohs micrographic surgery for definitive treatment. Staged excision with pathologic margin control is a simple, accessible, and curative procedure suggested for the treatment of high-risk basal cell carcinoma. Objective: To evaluate the results of staged excision of high-risk basal cell carcinoma in the head region. Methods: This interventional study was performed on patients with high-risk basal cell carcinoma, who underwent staged excision until the margins were free of tumor. Results: A total of 122 patients (47 females and 75 males) with mean age of 57.66 ± 9.13 years were recruited in this study. Nasal and nodular types were the most common of both clinical and pathologic forms, respectively. Further, 89.3 % of cases were cured by staged excision after four years of follow-up. There was a significant relationship between treatment outcomes and recurrent lesions, multiplicity of risk factors, long-standing disease, and pathologic type. There was also a significant association between the number of surgical excisions and multiplicity of risk factors, as well as recurrence, location, and size of basal cell carcinoma. Study limitations: Lack of magnetic resonance imaging assessment in cases of suspected perineural invasion. Conclusions: High-risk basal cell carcinoma had a high cure rate by staged excision. Patients with more risk factors and those with nasal and recurrent basal cell carcinoma required more staged excisions. Failure of treatment is more probable in patients with more risk factors, long-standing lesions, and high-risk pathologic and recurrent basal cell carcinomas.

ABSTRACT

Se describe el caso clínico de un anciano de 72 años de edad, quien presentaba un tumor cutáneo dorsal maligno, por lo cual fue atendido de forma multidisciplinaria en 2 hospitales de la provincia de Santiago de Cuba. Dado el diagnóstico preoperatorio de epitelioma basocelular de piel se procedió a la extirpación del tumor de forma ambulatoria. El resultado del estudio anatomopatológico no confirmó dicho diagnóstico, pero sí corroboró que se trataba de un fibroxantoma atípico. Con los márgenes quirúrgicos de seguridad amplios se logró la curación del paciente.


The case report of a 72 years old man who presented a dorsal cutaneous neoplasm is described, reason why he was assisted in a multidisciplinary way in 2 hospitals from Santiago de Cuba. Given the preoperative diagnosis of skin basal cell epithelioma the tumor was removed in an ambulatory way. The result of the pathologic study didn't confirm this diagnosis, but it corroborated that it was an atypical fibroxanthoma. With the wide surgical margins of security the patient's cure was achieved.

ABSTRACT

Abstract Secondary osteoma cutis is a phenomenon that may occur in several conditions. When it occurs in a melanocytic nevus it is named osteonevus of Nanta, an event considered uncommon and characterized by the presence of bone formation adjacent or interposed with melanocytic cells. There are reports of its occurrence in various melanocytic lesions, being more frequently associated with intradermal nevus. We report a case of osteonevus of Nanta in combined nevus, possibly the first description of this association.

ABSTRACT

Resumen: Introducción: El tumor de Bednar es un sarcoma de bajo grado, infrecuente, considerado como la variante pigmen tada del dermatofibrosarcoma protuberans (DFSP). Objetivo: describir las características clínicas, histopatológicas, el tratamiento y la evolución de un caso pediátrico de esta infrecuente neoplasia. Caso Clínico: escolar de 9 años que consultó por una pápula indurada asintomática, de dos años de evolución en el dorso del cuarto dedo del pie izquierdo. La biopsia incisional de la lesión fue com patibles con un DFSP pigmentado. El estudio inmunohistoquímico mostró positividad intensa para CD34 en toda la lesión, con factor XIIIa negativo. Se complementó el estudio de la pieza histológica con citogenética molecular FISH para el gen PDGFB (22q13.1) el cual reflejó un patrón anómalo en las células tumorales, no así en los melanocitos ni en la piel peritumoral. Se realizó cirugía micrográfica de Mohs diferida con cobertura mediante sustituto dérmico, sin recidiva ni recurrencia tumoral a los 5 años de seguimiento. Conclusiones: El DFSP pigmentado es un sarcoma de bajo grado, que muy infrecuentemente se presenta en pacientes pediátricos. Las variantes clásica y pigmentada deben ser sospechadas ante una lesión papulonodular única, de crecimiento lento y progresivo, con presencia de células fusiformes con patrón estoriforme en la biopsia y con estudio inmunohistoquímico positi vo para CD34. Es una entidad con buen pronóstico, con escaso riesgo de recurrencia y metástasis, si se logra la realización de una extirpación completa.


Abstract: Introduction: Bednar tumor is a rare low-grade sarcoma considered the pigmented variant of dermatofibrosarco ma protuberans (DFSP). Objective: To describe the clinical and histopathological characteristics, treatment and evolution of this rare neoplasm. Clinical Case: A 9-year old female presented with a 2-year history of an indurated, asymptomatic papule on the back of her fourth left toe. The incisio nal biopsy was compatible with pigmented DFSP. The immunohistochemical study showed intense positivity for CD34 throughout the lesion, with negative factor XIIIa. We complemented the study with molecular cytogenetics (FISH) for PDGFB gene (22q13.1) which showed an abnormal pattern in tumor cells, but not in the melanocytes or the peritumoral skin. Delayed Mohs surgery and skin substitute dressing were performed without neoplastic recurrence at 5 years of follow up. Conclu sion: Pigmented DFSP is a low-grade sarcoma that is very rare in pediatric patients. The classical and pigmented variants should be suspected in the presence of a single papulonodular lesion of slow and progressive growth, with presence of spindle cells with storiform pattern in the biopsy and positive immunohistochemical study for CD34. It is an entity with good prognosis, with little risk of recurren ce and metastasis, if complete excision is achieved.

ABSTRACT

El dermatofibrosarcoma protuberans (DFSP) es un tumor cutáneo, de baja frecuencia, fibrohistiocítico, infiltrante, de lento crecimiento, de agresividad local, de malignidad intermedia; con escasas probabilidades de metástasis pero con alto índice de recurrencia local. El diagnóstico debe sospecharse y confirmarse con histología e inmunohistoquímica. El tratamiento de elección es con cirugía convencional y/o cirugía micrográfica de Mohs, con márgenes de 2-4 cm. Se considera que la prevalencia del DFSP en la edad pediátrica es baja, debido al escaso índice de sospecha. En el presente trabajo compartimos cinco casos de DFSP en la edad pediátrica, estudiados en el Hospital General de Niños Pedro de Elizalde. (AU)


Dermatofibrosarcoma protuberans (DFSP) is a cutaneous, low frequency, fibrohistiocytic, infiltrating, slow growing, local aggressiveness, intermediate malignancy tumor; with little chance of metastasis but with a high rate of local recurrence. The diagnosis should be suspected and confirmed with histology and immunohistochemistry. The treatment of choice is with conventional surgery and / or Mohs micrographic surgery, with margins of 2-4 cm. The prevalence of DFSP in pediatric age is considered to be low, due to the low index of suspicion. In this paper we share five cases of DFSP in the pediatric age, studied at the Pedro de Elizalde Children's General Hospital. (AU)

ABSTRACT

Introdução: O couro cabeludo é uma área de difícil reconstrução devido à sua pouca elasticidade e por sobrepor-se a uma estrutura rígida e convexa. Existem diferentes técnicas cirúrgicas para reparação dos defeitos, que podem ser produto de diversas etiologias, como: traumas, deformidades e consequência de doenças, principalmente oncológicas, como é o caso do paciente apresentada neste trabalho. O angiossarcoma cutâneo é um tumor vascular maligno raro e extremamente agressivo, que afeta principalmente idosos. É caracterizado clinicamente pelo aparecimento de placas eritêmato-violáceas e de rápida evolução. O tratamento depende da extensão da doença. A maioria dos casos são tratados com ampla ressecção cirúrgica e reconstrução. O objetivo é relatar um caso de reconstrução de grande defeito do couro cabeludo depois de uma dissecção oncológica, realizado no Hospital Central do Exército (HCE) - RJ. Métodos: O caso foi tratado com enxerto autólogo e uso de matriz dérmica, em 2 tempos cirúrgicos, até a total cobertura da área lesionada. Resultados: Obteve-se resultado satisfatório após as cirurgias de enxertia de pele na área ressecada. Conclusão: O enxerto autólogo, juntamente a matriz dérmica mostrou-se uma opção viável na reconstrução do couro cabeludo.


Introduction: It is difficult to reconstruct the scalp due to its poor elasticity and presence of layers over a rigid convex structure. Different surgical techniques are used to repair defects that may develop due to several etiologies, such as trauma, deformities, and disease sequelae, especially cancer, as noted in the present case. Cutaneous angiosarcoma, a rare and extremely aggressive malignant vascular tumor that mainly develops in elderly individuals, is clinically characterized by the onset of rapidly evolving erythematous purple plaques. The treatment depends on disease extent. Most patients are treated with wide surgical resection and reconstruction. The objective is to report a case of reconstruction of a major scalp defect after an oncologic dissection performed at the Hospital Central do Exército in Rio de Janeiro. Methods: An autologous graft and dermal matrices were applied during two surgical periods till the damaged area was fully covered. Results: Satisfactory results were obtained after performing skin grafting surgery in the resected area. Conclusion: The autologous graft and dermal matrix proved to be a viable option for scalp reconstruction.
