RESUMO

Corpos riziformes são estruturas que podem ser encontradas no líquido sinovial ou aderidas à sinóvia, que se assemelham macroscopicamente a grãos de arroz. São frequentes em pacientes com artrite reumatoide e decorrem de resposta inflamatória crônica. São encontrados em 25% dos procedimentos de aspiração ou cirurgias das articulações. Porém, ainda não existem publicações relatando sua presença no subcutâneo. Relatamos, pela primeira vez, a ocorrência de corpos riziformes no subcutâneo da região palmar em paciente com artrite reumatoide, confirmados por exames ultrassonográfico e anatomopatológico, tratados com sucesso com drenagem cirúrgica, sem recidivas após dois anos de seguimento


Riziform bodies are structures in the synovial fluid or attached to the synovium, which macroscopically resemble rice grains. They are common in patients with rheumatoid arthritis and result from a chronic inflammation. They are found in 25% of aspiration procedures or joint surgery. However, there are still no publications reporting its presence in the subcutaneous tissue. We report for the first time the occurrence of riziform bodies in the subcutaneous plane of the palmar region in a patient with rheumatoid arthritis, confirmed by sonographic and anatomopathological examination, successfully treated with surgical drainage, without recurrences after two years of follow-up.

RESUMO

A tatuagem é uma prática antiga e muito popular atualmente. Os pigmentos utilizados mudaram com o tempo, mas continuam apresentando composições variadas e pouco regulamentadas. Há inúmeros casos descritos de efeitos adversos pós-tatuagem, em sua maioria infecciosos, e reações de hipersensibilidade. Relatamos o caso de uma mulher de 64 anos, hígida, com pápulas nas sobrancelhas um mês após realizar micropigmentação. A biópsia excisional fez o diagnóstico de molusco contagioso, e o tratamento foi realizado com curetagem das lesões. Na literatura, existem poucos relatos de disseminação de molusco contagioso causada por tatuagem.


Tattooing is an ancient practice and very popular nowadays. The pigments used have changed over time but still present varied and poorly regulated compositions. There are many described cases of adverse effects after tattooing, mainly infectious and hypersensitivity reactions. We report the case of a 64-yearold woman, healthy, with papules on her eyebrows one month after performing micropigmentation. The excisional biopsy diagnosed molluscum contagiosum, and the lesions were curetted. There are few reports in the literature of the spread of molluscum contagiosum caused by tattooing

RESUMO

Neurofibromatose tipo I (NF1) é uma doença autossômica dominante, com incidência de 1/2.500-3.000 nascimentos e prevalência de aproximadamente 1/4.000-5.000 indivíduos; é causada por mutações genéticas no gene NF1, que afetam tecidos neurais e cutâneos. Tumor glômico é uma neoplasia benigna originada do glomo, uma estrutura neuromioatrial da pele presente nas pontas dos dedos e envolvida na termorregulação. São considerados historicamente tumores isolados esporádicos, porém existem estudos que comprovam sua relação com a neurofibromatose tipo I. Pacientes com neurofibromatose tipo 1 devem ser investigados. O relato de caso fornece suporte adicional à noção de que NF1 tem um risco associado a múltiplos tumores glômicos.


Neurofibromatosis type I (NF1) is an autosomal dominant disease, with an incidence of 1/2,500-3,000 births and a prevalence of approximately 1/4,000-5,000 individuals. Genetic mutations in the NF1 gene cause it, affecting neural and skin tissues. Glomus tumor is a benign neoplasm originating from the glomus, a neuromyoatrial structure of the skin present at the fingertips and involved in thermoregulation. The literature historically considered these tumors isolated and sporadic, but some studies have proved a relationship with neurofibromatosis type I. Thus, patients with neurofibromatosis type 1 should be investigated. The case report provides additional support for the notion that NF1 has a risk associated with multiple glomus tumors.

RESUMO

Abstract Porokeratosis is a skin disorder clinically characterized by annular plaques with keratotic borders resembling the Great Wall of China and histopathologically by cornoid lamellae. The disease has several clinical variants. Porokeratosis ptychotropica, which has recently become part of these variants, is quite rare and little known. The entity is characterized by verrucous plaques – which may resemble a psoriasis plaque – that affect the regions of the buttocks, most commonly the gluteal cleft, with or without extremity involvement. Itching is often present. We report a rare case of porokeratosis ptychotropica and highlight its unusual manifestation (single plaque), the first case reported in the Brazilian literature.

RESUMO

Abstract Plasmoacanthoma is an extremely rare verrucous tumor located on periorificial regions characterized by dense dermal plasmacytic infiltrates. Some authors classify it as a form of reactive plasma cell proliferation which represents a heterogeneous spectrum of mucocutaneous disorders. These plasma cell proliferations have been considered to be a benign immunologic inflammatory reaction to known or unknown stimuli. However, the etiology of plasmoacanthoma remains highly speculative. We report the case of a 40-year-old woman who presented with a lobulated warty lesion affecting the lower lip. Biopsy from the lesion was compatible with plasmoacanthoma, which remains an underreported disease in the dermatology literature.

RESUMO

Abstract Lupus tumidus is considered a rare subtype of chronic cutaneous lupus erythematosus, characterized by erythema and bright urticarial erythematous-violaceous lesions that leave no scars after regression. Histopathology reveals perivascular and periannexal lymphohistiocytic infiltrates in the papillary and reticular dermis and interstitial mucin deposition. Treatment is based on photoprotection, topical corticosteroids and antimalarials. We report two cases of lupus tumidus, which deserve attention for their low frequency in the literature, in addition to their relevance as a differential diagnosis among dermatologic disorders.

RESUMO

Cutaneous metastasis is a rare manifestation of visceral malignancies that indicates primarily advanced disease. Due to its low incidence and similarity to other cutaneous lesions, it is not uncommon to have a delayed diagnosis and a shortened prognosis. We describe the case of a patient who presented with a cutaneous nodule in the sternal region as a first sign of malignancy.

RESUMO

Glomus tumors originate from modified perivascular muscle cells. The most common form is the solitary one. The multiple form may be associated with dominant genetic inheritance. We report a case of a patient with hemangiomatous lesions on the calcaneus and wrist since birth. In 6 years, there was progression of lesions throughout the body. Multiple glomangiomas are asymptomatic and more common in childhood. They can be confused with other vascular malformations. Histopathological diagnosis is essential. The case shows a type 2 segmental manifestation that can be explained by genetic mutation leading to the loss of heterozygosity. As the child grows, the lesions may disseminate due to mutation in distant parts of the skin. Literature shows few reports. The treatment is conservative.

RESUMO

Tumor of the follicular infundibulum is a rare benign cutaneous adnexal neoplasm with variable clinical presentation. In most cases the diagnosis is made with the help of histopathology, due to lack of a characteristic clinical presentation. The most common form is a solitary lesion, but it can be multiple or eruptive, then called infundibulomatose. This case report illustrates a patient with multiple lesions of tumor of the follicular infundibulum with bizarre aspect and atypical location.

RESUMO

Sarcoidosis is a multisystem granulomatous disease of unknown cause. The osteoarticular involvement in sarcoidosis is rare and is often associated with cutaneous and long-standing chronic multisystem disease. More common in black women, osseous sarcoidosis is difficult to diagnose, with an incidence of 3 to 13%. The most characteristic radiological clinical picture evidences rounded, well-defined cysts, with no periosteal reaction and without peripheral sclerosis. The small bones of hands and feet are the most frequently involved sites. This report aims to demonstrate a rare case of osteoarticular sarcoidosis with characteristic clinical presentation, and highlight the importance of detecting osteoarticular involvement in this pathology.

RESUMO

Ewing sarcoma is a primitive neuroectodermal tumor rarely occurs in the skin and sobcutaneous tissues. Generally Ewing's sarcoma is a primary bone tumor, but when present in soft tissues it characterizes an extremely uncommon clinical picture. It usually involves the deep subcutaneous tissue or muscles, and more rarely occurs like a primary skin cancer. Most patients are white, women, and in the second decade of life. The clinical features are a superficial mass, in average measuring 2-3 cm, of soft consistency, freely mobile and sometimes painful. The more affected locations are upper and lower extremities, trunk, head, neck or multiple lesions. The presence of metastases is very rare.

RESUMO

Os neuromas encapsulados em paliçada são tumores neurais solitários da pele caracterizados pela presença de feixes compactos e paralelos de fascículos de células de Schwann. Apresenta-se um caso desse tumor, confirmado por exame anatomopatológico, em paciente do sexo feminino, de 55 anos, que relatou mácula hipocrômica de crescimento que evoluiu para pápula de superfície lisa e em domo, com telangiectasias, simulando carcinoma basocelular. Ter conhecimento dessa entidade é importante para a realização de diagnósticos diferenciais com outras lesões, em especial com o CBC, tumores de apêndice cutâneo, nevos e cistos epidérmicos.


Palisaded encapsulated neuromas are solitary neural skin tumors characterized by the presence of compact and parallel bundles of Schwann cell fascicles. The present article reports a case of this type of tumor, which was confirmed by anatomic pathological examination of a 55-year-old female patient who reported hypochromic macula growth, which had evolved into a smooth domed superficial papule with telangiectasias, simulating a basal cell carcinoma. Having knowledge of this entity is crucial in order to carry out differential diagnoses-comparing it to other lesions-especially basal cell carcinomas, skin appendage tumors, nevi, and epidermal cysts.
