ABSTRACT

Hemangioma infantil (HI) é o tumor vascular mais comum e a neoplasia benigna mais frequente da infância, com maior incidência no sexo feminino e na população branca. Quase 60% dos casos ocorrem em cabeça e pescoço, sendo o tratamento ativo durante a fase proliferativa mais frequentemente indicado, em decorrência dos possíveis problemas funcionais e do potencial desfigurante. Relatamos um caso de paciente com hemangioma infantil involuído de ponta nasal e lábio superior, tratado de forma expectante durante a infância, submetida à correção da deformidade residual com técnicas de rinoplastia, associado à zetaplastia e lipoenxertia do lábio superior com bom resultado e satisfação do paciente.


Infantile hemangioma (IH) is the most common vascular tumor and the most frequent benign neoplasm in childhood, with the highest incidence in females and the white population. Almost 60% of cases occur in the head and neck, and active treatment during the proliferative phase is the most frequently indicated, due to possible functional problems and disfiguring potential. We report a case of a patient with involute infantile hemangioma of the nasal tip and upper lip, treated expectantly during childhood, submitted to residual deformity correction with rhinoplasty techniques, associated with zetaplasty and upper lip grafting with good results and patient satisfaction.

ABSTRACT

RESUMEN: Las anomalías vasculares de cabeza y cuello son un grupo de lesiones que afectan vasos sanguíneos y linfáticos donde el tratamiento sigue siendo un desafío. La clasificación actualizada de anomalías vasculares de cabeza y cuello es la clasificación de Mulliken modificada, que las subdivide en a) tumores vasculares y, b) malformaciones vasculares. En este reporte, presentamos dos casos clínicos de pacientes de sexo masculino, con diagnóstico de anomalías vasculares que afectan al labio y paladar duro, diagnosticados como malformación arteriovenosa y malformación venosa, respectivamente. Dichas lesiones remitieron completamente mediante tratamientos conservadores (agentes esclerosantes) y/o quirúrgicos (exéresis quirúrgica completa de la lesión) logrando una remisión completa. Consecutivamente, presentamos una revisión de la literatura enfocado a la clasificación actual, enfoques terapéuticos actuales y futuros.


ABSTRACT: Vascular anomalies of the head and neck are a group of lesions that affect blood and lymph vessels where treatment remains a challenge. The updated classification of head and neck vascular anomalies is the modified Mulliken classification, which subdivides them into a) vascular tumors and b) vascular malformations. In this report, we present two clinical cases of male patients, with diagnosis of vascular anomalies affecting the lip and hard palate, diagnosed as arteriovenous malformation and venous malformation, respectively. These lesions were completely treated with conservative (sclerosing agents) and/or surgical (complete surgical exeresis of the lesion) treatments, achieving a complete remission. Consequently, we present a review of the literature focused on the current classification, current and future therapeutic approaches.

ABSTRACT

Resumen Introducción Los leiomiosarcomas de la vena cava inferior son tumores raros, sólo hay 300 casos descritos en la literatura. Su incidencia es mayor en mujeres, suelen aparecer entre los 50-60 años, y presentan una progresión lenta y mal pronóstico. Los síntomas son inespecíficos haciendo que el diagnóstico se realice de forma tardía, éste se realiza mediante pruebas de imagen y biopsia guiada. Caso clínico Se presenta el caso de un varón de 73 años con diagnóstico de leiomiosarcoma de la vena cava inferior, como hallazgo incidental en TC de control, tratado mediante radioterapia neoadyuvante, cirugía y radioterapia intraoperatoria. Discusión El único tratamiento que ha descrito modificaciones en la supervivencia es la cirugía. El papel de la adyuvancia y neoadyuvancia en estos tumores es muy controvertido. La elección de la actitud terapéutica dependerá de la localización del tumor, tamaño, la relación con estructuras adyacentes y la presencia de circulación colateral.


Introduction Leiomyosarcomas of the inferior vena cava are rare tumors, with fewer than 300 cases reported. Its incidence is higher in females, usually appear in the sixth decade and they have a slow-growing and poor prognosis. Symptoms are generally non-specific. Diagnosis is made with imaging studies and guided biopsy. Clinical Case We report a case of a 73-year-old male patient with leimyosarcoma of the inferior vena cava treated by neoadjuvant radiotherapy, surgery and intraoperative radiotherapy. Discussion Surgery is the only treatment that can improve the survival. The role of the adjuvancy and neoadjuvancy is very controversial. Surgical management is determined by the location of the tumour, the relationship with adjacent structures and the presence of collateral veins.

ABSTRACT

Cavernous hemangiomas are benign neoplasms of endothelial cells. Although this neoplasm has the potential to develop in all parts of the body, it rarely develops in the axilla; in fact, there are only two case reports of axillary cavernous hemangiomas in the literature. Here, we describe a third case, which occurred in a 30-year-old Korean woman. The patient presented with a palpable mass in the left axilla that was initially thought to be either a phyllodes tumor or a lymphoma based on imaging studies. However, the results of an excisional biopsy led to a diagnosis of cavernous hemangioma. Although uncommon, a cavernous hemangioma can be encountered unexpectedly, presenting as a mass in axilla. Although usually curative, surgery may be challenging not only because of the rarity of the condition, but also because of inconsistent preoperative findings and the involvement of large vessels.

ABSTRACT

Pyogenic granuloma is one of the benign vascular neoplasm. The nomenclature is misnomer because pyogenic granuloma is not related to infection and granuloma. It represent histopathologically lobular capillary hemangioma. It is most commonly occurred on skin followed by oral cavity such as gingiva, lip, tongue and buccal mucosa. Herein, we report a extremely rare case of pyogenic granuloma which was developed on larynx of a 81 year-old male with review of literature.

ABSTRACT

Kaposiform hemangioendothelioma (KHE) is a very rare, locally aggressive vascular neoplasm. It occurs mostly in children and is rarely observed in adults. It typically originates on the skin, later affecting the deep soft tissue of the extremities, head or neck, and retroperitoneum by infiltrative growth. It is locally aggressive, does not regress spontaneously, and tends to metastasize locally as well as to the regional lymph nodes. In this article, we report a case of adult-onset KHE with neurofibromatosis type 1. The patient presented to our department with a 2-month history of a painful ulceration in her left popliteal area. Since KHE had not previously been reported in patients with neurofibromatosis, the diagnosis was difficult due to the similarity of the skin manifestation to neurofibromatosis-associated lesions. We share our experience of diagnosing and treating this rare case of adult-onset KHE.

ABSTRACT

Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a primary headache syndrome with an unclear pathogenesis. However, there is increasing evidence in the literature for secondary SUNCT being attributable to certain known lesions. We explored the possible neurobiological mechanism underlying SUNCT based on all reported cases of secondary SUNCT for which detailed information is available. Here we report a case of neuromyelitis optica spectrum disorders that had typical symptoms of SUNCT that might have been attributable to involvement of the spinal nucleus of the trigeminal nerve. We also review cases of secondary SUNCT reported in the English-language literature and analyze them for demographic characteristics, clinical features, response to treatment, and imaging findings. The literature review shows that secondary SUNCT can derive from a neoplasm, vascular disease, trauma, infection, inflammation, or congenital malformation. The pons with involvement of the trigeminal root entry zone was the most commonly affected region for inducing secondary SUNCT. In conclusion, the neurobiology of secondary SUNCT includes structures such as the nucleus and the trigeminal nerve with its branches, suggesting that some cases of primary SUNCT have underlying mechanisms that are related to existing focal damage that cannot be visualized.

ABSTRACT

Microvenular hemangioma (MVH) is a rare acquired benign vascular neoplasm, which presents commonly as a solitary purple-to-red nodule or plaque measuring approximately 10 mm in diameter. MVH occurs primarily on the extremities or the trunk. Most lesions are solitary, and multiple lesions are rare. Histopathological features of MVH include numerous, scattered, thin and irregularly branching small vessels in the dermis and endothelial cells without atypia. Owing to similarities in clinical morphology and histopathological features, MVH may often be indistinguishable from the early patch stage of Kaposi sarcoma. Immunohistochemical (IHC) analysis helps differentiate between the 2 diseases. The results of IHC tests in patients with MVH show positive staining for CD31 and smooth muscle actin and typically, negative staining for the human herpes virus 8 antigen. We report a rare case of multiple MVH clinically mimicking the early patch stage of Kaposi sarcoma in a 63-year-old woman who presented with a 3-year history of slowly growing, compressible, soft, bluish-purple macules and plaques on the trunk and right arm.

ABSTRACT

Hemangioendothelioma is a rare vascular tumor with involvement of the liver, brain, long bones, and lung. Among the 6 histological subtypes, epithelioid hemangioendothelioma (EHE) is the most aggressive. Its occurrence in the mediastinum is quite rare, and very few cases have been documented. The reported cases in the literature have described difficulties in the preoperative diagnosis due to the unusual histological appearance of the tumor. Immunohistochemistry remains the mainstay for a definitive diagnosis. Due to its low incidence, there is no standard treatment for mediastinal EHE, but curative resection is the preferred treatment option where possible, with chemotherapy used as an adjuvant treatment or in cases of widespread inoperable disease. The present case study describes an aggressive EHE occurring in an 18-year-old woman in the anterior mediastinum.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the risk factors of vascular invasion in patients with early gastric cancer (EGC), and to investigate the influence of vascular invasion on the prognosis of EGC patients.</p><p><b>METHODS</b>From January 2014 to December 2015, 449 EGC patients underwent curative gastrectomy at the First Affiliated Hospital of Anhui Medical University, of whom 27 cases (6.0%) developed vascular invasion. Clinicopathological and follow-up data of EGC cases were analyzed retrospectively. The association between clinicopathological features and vascular invasion was analyzed by using the Chi-square test or Fisher exact test, and the independent risk factors influencing vascular invasion were identified with logistic regression. The influence of vascular invasion on overall survival was investigated with Kaplan-Meier curve. This study was approved by Ethics Committee of The First Affiliated Hospital of Anhui Medical University (No. 2018-03-12).</p><p><b>RESULTS</b>Of 449 EGC patients, 325 were males and 124 were females (ratio 2.6:1.0) with the mean age of (60.8±10.5) (27 to 87) years; 228 were diagnosed as T1a stage and 221 were diagnosed as T1b. Univariate analysis showed that incidence of vascular invasion in EGC patients with ulceration or scar was 8.4%(18/225), which was higher than 3.8%(9/234) in those without ulceration, and the difference was statistically significant (χ²=4.061, P=0.044). The incidence of vascular invasion in patients with low differentiated tumor was 8.8% (20/226), which was significantly higher than 3.1%(7/223) in those with middle-high differentiated tumor(χ²= 8.363, P=0.012). The incidence of vascular invasion in patients staging T1b was 10.9% (24/221), which was significantly higher than 1.3% (3/228) in those staging T1a (P=0.000); The incidence of vascular invasion in patients with lymph node metastasis was 27.3% (15/55), which was significantly higher than 3.0%(12/394) in those without lymph node metastasis (χ²=50.122, P=0.000). However, there were no significant associations of vascular invasion with gender, age, surgical type, multiple tumor, tumor deposit, tumor location and tumor size (all P > 0.05). Multivariate analysis showed that T1b stage (RR=4.653, 95%CI:1.293-16.747, P=0.019) and lymph node metastasis(RR=7.302, 95%CI: 3.063-17.408, P=0.000) were independent risk factors for vascular invasion in EGC patients. Among 449 EGC patients, 444 received complete follow-up(98.9%), including 26 cases with vascular invasion and 418 cases without vascular invasion. The overall survival in vascular invasion group was significantly lower than that in non-vascular invasion group (χ²=60.463, P=0.000). Besides, 198 EGC patients gained follow-up for 3 years, and the 3-year survival rates of 11 vascular invasion cases and 187 non-vascular invasion cases were 54.5% and 96.8% respectively.</p><p><b>CONCLUSIONS</b>The risk of vascular invasion is higher in EGC patients with lymph node metastasis and tumor infiltrating the submucosa. The prognosis of EGC patients with vascular invasion is poor.</p>

ABSTRACT

ABSTRACT Background: Pancreatic adenocarcinoma remains one of the worst digestive cancers. Surgical resection is the main target when treating a patient with curative intent. Aim: To assess angiolymphatic invasion as a prognostic factor in resected pN0 pancreatic cancer. Methods: Thirty-eight patients were submitted to pancreatoduodenectomy due to head pancreatic cancer. Tumor size, margins, lymph nodes, pTNM staging, angiolymphatic and perineural invasion were described in the pathologists' reports. Results: Most patients were female. Overall median survival was 13 months. Gemcitabine was the regimen of choice for chemotherapy in selected patients; however, it did not improve overall survival. pR0 resection had better survival compared with pR1. Within the pN0 group, survival was significantly better in patients without angiolymphatic invasion. Conclusion: Angiolymphatic invasion in N0 pancreatoduodenectomy can be demonstrated by the Hematoxylin-Eosin stain and may predict a poor prognosis factor for those patients.


RESUMO Racional: Adenocarcinoma pancreático continua sendo um dos piores cânceres do aparelho digestivo. A ressecção cirúrgica é o principal objetivo quando se trata de intenção curativa. Objetivo: Avaliar a invasão angiolinfática como um fator prognóstico no câncer da cabeça do pâncreas ressecado pN0. Método: Trinta e oito pacientes foram submetidos a duodenopancreatectomia por câncer da cabeça do pâncreas. Tamanho do tumor, margens, linfonodos, estadiamento pTNM, invasão angiolinfática e perineural foram descritos nos laudos anatomopatológicos. Resultados: A maioria foi de mulheres. A sobrevida mediana global foi de 13 meses. Gencitabina foi a droga de escolha para quimioterapia nos pacientes selecionados, entretanto não aumentou a sobrevida global. Pacientes com ressecção pR0 tiveram sobrevida global superior quando comparados com ressecção pR1. Dentro do grupo de pacientes com pN0, a sobrevida foi significativamente melhor no grupo de pacientes que não apresentavam invasão angiolinfática. Conclusão: A invasão angiolinfática da duodenopancreatectomia N0 pode ser demonstrada utilizando apenas a hematoxilina-eosina e pode predizer prognóstico ruim para estes pacientes.

ABSTRACT

Kaposi's sarcoma (KS) is a vascular neoplasm originating from vascular and lymphatic endothelial cells. Iatrogenic KS mainly develops in organ transplant patients or after receiving immunosuppressive therapy. An 81-year-old man presented with multiple dark-purplish nodules, plaques, and patches on the right leg for 3 weeks. Previously, the patient was treated with prednisolone 10∼30 mg/day for chronic obstructive pulmonary disease for 3 months, and percutaneous transluminal angioplasty was performed 1 month previously for the treatment of peripheral arterial occlusive disease. A biopsy specimen of the nodule showed closely packed spindle cells forming slit-like vascular structures, which were consistent with KS. Despite the dosage reduction of prednisolone for treatment, the skin lesions progressed aggressively throughout the entire body, and the patient died after 5 months. We report a case of iatrogenic prednisolone-associated KS rapidly progressing to the entire body shortly thereafter.

ABSTRACT

Glomanigiopericytoma is a rare vascular neoplasm with a perivascular myoid phenotype. It is rarely found in the neck but most commonly in the nose and paranasal sinuses. We experienced a case of 72-year-old man who presented a 5-year history of a right neck mass. The pathologic diagnosis was glomangiopericytoma. We removed the mass transcervically and the patient showed no postoperative problem. We report this case with a review of literature.

ABSTRACT

Hemangiosarcoma (HSA) is a malignant neoplasm originating from the vascular endothelium, with high metastatic power and commonly described in the spleen, liver, and right atrium. Thus, the objective of the present study is to report the occurrence of HSA at the base of the left atrium of a male, elderly, Lhasa Apso dog, treated with cyanosis, orthopedic position, cough. In the physical examination, the presence of crackling was observed in pulmonary lobes, murmur in focus of mitral and tricuspid grade IV\VI. The recommended emergency therapy was performed until the clinical improvement of the animal. After echocardiography, mitral and tricuspid valvular degeneration was confirmed, as well as the presence of an irregular, mixed echocardiogram, extra-cardiac, immobile at the base of the left atrium, measuring 2.9 x 1.44 cm in diameter. The clinical therapy established stabilized the clinical picture for 128 days, with recurrence of pulmonary edema and severe hemorrhagic pleural effusion, with the owners opting for euthanasia of the animal and necropsy confirming the definitive diagnosis of extrahepatic SAH at the base of the left atrium.(AU)


O hemangiossarcoma (HSA) é uma neoplasia maligna originada no endotélio vascular, com alto poder metastático e comumente descrito no baço, fígado e átrio direito. Assim, o objetivo deste trabalho é relatar a ocorrência do HSA na base do átrio esquerdo de um cão, macho, idoso, da raça Lhasa Apso, atendido apresentando cianose, posição ortopneica e tosse. No exame físico foi observado presença de crepitação em lobos pulmonares e sopro em foco de mitral e tricúspide grau IV\VI. Foi realizada terapia emergencial preconizada até a melhora clínica do animal, e após a ecocardiografia confirmou-se a degeneração valvular mitral e tricúspide, bem como a presença de uma imagem irregular, de ecogenicidade mista, extracardíaca e imóvel na base do átrio esquerdo, medindo 2,9 x 1,44 cm de diâmetro. A terapia clínica instituída estabilizou o quadro clínico por 128 dias, havendo recidiva do edema pulmonar e efusão pleural hemorrágica grave, com os proprietários optando pela eutanásia do animal e a necropsia, confirmando o diagnóstico definitivo do HSA extracardíaco na base do átrio esquerdo.(AU)
