ABSTRACT

O Granuloma central de células gigantes é próprio dos ossos gnáticos, sendo um tumor benigno não odontogênico. É uma lesão de crescimento normalmente lento, bem circunscrito e assintomático, geralmente diagnosticado através de algum exame de rotina ou, em casos mais avançados, quando se começa a visualizar alguma alteração estético-anatômica. O tratamento de eleição para este tipo de lesão é a simples curetagem ou a ressecção em bloco. No entanto, em pacientes adultos jovens e em crianças, o efeito mutilante que este tipo de tratamento pode acarretar deve ser levado em consideração, utilizando tratamentos não cirúrgicos, como injeção intralesional de corticosteroides, administração de interferon alpha e calcitonina. Assim, o objetivo deste trabalho é relatar um caso de tratamento com ressecção segmentar de granuloma central de células gigantes. Tumores mais agressivos e recorrentes devem ser submetidos à ressecção e mesmo assim deve se levar em consideração o efeito estético que pode causar na face do paciente, principalmente, se forem crianças e adultos jovens... (AU)


The central granuloma of giant cells is specific to gnathic bones, being a benign non-odontogenic tumor. It's a growth injury usually slow, well circumscribed and asymptomatic, usually diagnosed through some routine examination or, in more advanced cases, when it begins to visualize some aesthetic-an atomical alteration. The treatment of choice for this type of injury is a simple curettage or resection in block. However, in young adult patients and children, the mutilating effect that this type of treatment can bring must be taken in to consideration, using non-surgical treatments, such as intralesional injection of corticosteroids, administration of alpha interferon and calcitonin. Therefore, the objective of this work is to report a case of treatment with resection segment of central granuloma of giant cells. More aggressive and recurrent tumors must be submitted to resection and even then taking into account the aesthetic effect it can have on the patient's face, especially if they are children and young adults...

ABSTRACT

RESUMO: O Tumor de Células Gigantes é uma neoplasia osteolítica benigna, porém agressiva, ricamente vascularizada e com numerosas células gigantes com atividade osteoclástica. Ocorre mais frequentemente nas epífises de ossos longos e raramente acomete as costelas (cerca de 1% dos casos). A apresentação deste tumor em porção anterolateral de arco costal é extremamente rara em comparação com a região posterior. O presente relato descreve o caso de uma paciente que apresentava uma tumoração dolorosa em parede torácica anterolateral esquerda, de crescimento insidioso. Exames de imagem revelaram uma lesão insuflativa em 10º arco costal esquerdo (4,2 x 3,5 cm), com áreas de calcificação interior. A paciente foi submetida a tratamento cirúrgico, com ressecção ampla do tumor, englobando 9º, 10º e 11º arcos costais e uma porção do diafragma. O diagnóstico definitivo de tumor de células gigantes se deu pela imunohistoquímica da peça cirúrgica. Este relato permite fornecer bases para o estudo das possibilidades terapêuticas desta patologia em localizações atípicas, reforçando que a exérese em bloco com margens amplas destes tumores promove uma menor chance de recidiva local. (AU)


ABSTRACT: Giant Cell Tumor is a benign but aggressive osteolytic neoplasm, richly vascularized and with numerous giant cells with osteoclastic activity. It often occurs in long bone epiphyses and rarely affects the ribs (about 1% of cases). The presentation of this tumor in the anterolateral portion of the costal arch is extremely rare compared to the posterior region. The present report describes the case of a patient who had a painful tumor on the left anterolateral chest wall, of insidious growth. Imaging exams revealed an insufflating lesion in the 10th left costal arch (4.2 x 3.5 cm), with areas of interior calcification. The patient underwent surgical treatment, with wide resection of the tumor, comprising 9th, 10th and 11th ribs and a portion of the diaphragm. The definitive diagnosis of giant cell tumor was made by immunohistochemistry of the surgical specimen. This report provides a basis for studying the therapeutic possibilities of this pathology in atypical locations, reinforcing that the block excision with wide margins of these tumors promotes a lower chance of local recurrence.

ABSTRACT

Undifferentiated carcinoma of the pancreas with osteoclast-like giant cells (UCOGCs) is an extremely rare morphologically and clinically distinct variant of pancreatic ductal adenocarcinoma (PDAC), exhibiting a characteristic component of reactive osteoclast-like giant cells admixed with neoplastic mononuclear cells. Sommers and Meissner first described it in 1954 as an "unusual carcinoma of the pancreas". Later it acquired many different names. In 2010, the WHO classified these tumors as a variant of PDAC under the heading of "undifferentiated carcinoma with osteoclast-like giant cells". Here we describe the first case of pancreatic mixed neuroendocrine-non-neuroendocrine neoplasms (MiNEN) composed of UCOGC and pancreatic neuroendocrine tumor (NET), which occurred in a 78-year-old man with biliary colic and pancreatitis. The mass did not respond to the chemotherapy, and he soon developed liver metastasis from the NET component, and unfortunately, the patient passed away 10 months later. Since UCOGC is extremely rare, and its association with NET has not been reported yet, our case expands the knowledge regarding its unusual presentation and poor prognosis.

ABSTRACT

Abstract Multinucleate cell angiohistiocytoma is a rare, benign vascular proliferation of unknown etiology. It occurs mainly in middle-aged women and usually affects the acral regions; the lesions appear as discrete, grouped, and asymptomatic violaceous papules. Histopathology shows proliferation and dilated small vessels in the papillary dermis, fibrous stroma with thickened collagen bundles, and multinucleated giant cells. To date, there are approximately 140 cases described in the indexed literature. This report presents the case of a 62-year-old woman with a typical clinical condition, who chose not undergo treatment, considering the benign character of her illness. The clinical and immunohistological aspects of this unusual dermatological entity are emphasized.

ABSTRACT

La enfermedad de Erdheim-Chester (EEC) es una histiocitosis de células no Langerhans de presentación proteiforme y escaso conocimiento. Se presenta una serie de 19 casos de 4 centros, registrados de junio de 2012 a junio de 2019. Se incluyeron aquellos pacientes con clínica, anatomía patológica e inmunohistoquímica característica de la enfermedad. Se excluyeron pacientes con hallazgos indefinidos. Resultados: al igual que en la literatura, el compromiso más frecuente fue el óseo por imagenología, la mitad de estos sintomático. Nuestra serie presenta mayor incidencia de mujeres (casi 70%). Siete pacientes presentaron nódulo mamario como forma de presentación. La mayoría recibieron dosis media de esteroides asociado a otra droga inmunosupresora. La mortalidad fue del 16%. Conclusión: comunicamos una serie de pacientes con la EEC mencionando las características más destacables. Es llamativo el número de pacientes con afectación mamaria, por lo cual proponemos téngase en cuenta en el diagnóstico diferencial de la patología tumoral mamaria.


Erdheim-Chester disease (ECD) is a non-Langerhans histiocytosis, protein manifestations at start and little known. We included 19 patients from June 2012 to June of 2019. Inclusion criteria: clinical features, histopathology and immunostaining compatible with ECD. We excluded patients with undefined features. Results: Bones were the most frequent affected, half of them were asymptomatic. Seventy per cent of the patients were women, and 7 of them developed a nodule breast as first manifestation of ECD. The patients were treated with corticosteroids associated or not with immunosuppressants. The mortality rate was 16%. Conclusion: We reported a series of patients with ECD, enhancing the most frequent features. It is striking the number of patients with breast involvement; we propose to include the Erdheim-Chester disease in differential diagnosis of breast tumor.

ABSTRACT

Giant cell reparative granuloma (GCRG) was first described in the 1950s. It is an uncommon and benign reactive tumor that is believed to occur after trauma or inflammation. It most commonly occurs in the maxilla and mandible and rarely affects the nasal cavity. It is often seen in children and during the second to third decades of life, predominantly seen among females. Histopathologically, GCRG shows many osteoclast-like multinucleated giant cells scattered in a background of mononuclear stromal cells and spindle-shaped fibroblasts also associated with areas of hemorrhage. The distinction between GCRG and giant cell tumors (GCT)is crucial since both have a similar clinical and histological presentation, but both have different management. GCTs have malignant potential, may metastasize, and have a high rate of recurrence. Surgical excision is the mainstay therapy of GCRG to ensure a low rate of recurrence. Here we discuss two cases GCRG, both presenting as nasal mass.

ABSTRACT

Caso de litiasis renal por oxalato de calcio asociado a enfermedad de Crohn de reciente debut en paciente masculino 43 años proveniente del Canton las Piñas, Provincia El Oro en Ecuador, sin antecedentes patológicos en relación a su enfermedad. En enero 2020 acude a consulta particular con dolor en fosa iliaca derecha, fiebre, fatiga, hiporexia, pérdida de peso, tenesmo y diarrea. Gastroenterólogo observó colon derecho con úlceras, áreas de mucosa infiltrada, y el estudio anatomopatológico identifica ulceraciones en subserosa, abscesos, infiltrado inflamatorio mixto, granulomas epitelioides con células gigantes multinucleadas. Previo consentimiento se realiza ecosonografía, detectándose un cálculo renal derecho de 5 mm de tamaño y otro de 4 mm en el izquierdo. El análisis de orina reporta aciduria, cristales oxalato de calcio y la radiografía simple demostró sombra de los cálculos. El estudio metabólico la 1,25 dihidroxivitamina D y la hormona paratiroidea resultó negativo. La evolución fue favorable y continua en control periódico que de ameritar se ordenaría tomografía helicoidal sin contraste o urograma excretorio.


We present a case of kidney stones due to calcium oxalate stones associated with Crohn's disease of recent debut in a 43-year-old male patient from the Piñas canton-El Oro Province-Ecuador with no personal and family pathological history in relation to his disease and that in January 2020 he went to a private medical consultation for presenting colic-type abdominal pain located in the right iliac fossa, fever, fatigue, hyporexia, weight loss, tenesmus and sometimes diarrhea. The gastroenterologist observed: right colon with ulcers and infiltrated mucosa areas; samples are taken for histopathological study. Anatomopathology It was identified ulcerations in subserosa, abscesses, mixed inflammatory infiltrate, epithelioid granulomas with multinucleated giant cells diagnosed with Crohn's disease. With the patient's consent, an echo-sonographic study was made, detecting a right kidney stone 5 mm in size and 4 mm in the left. Urinalysis showed aciduria, calcium oxalate crystals, and plain abdominal radiography showed shadow of the stones. In the metabolic study the 1,25 dihydroxyvitamin D and parathyroid hormone was negative. The evolution was favorable and he continuous in periodic control that, if it's required, would be ordered a helical computed tomography without contrast or excretory urogram.

ABSTRACT

Giant cell myocarditis (GCM) is a rare and rapidly fatal cardiovascular condition most often seen in young adults. It is characterized microscopically by myocardial necrosis with multinucleated giant cells in the absence of well-defined granulomas. This disorder has typically been attributed to manifest as heart failure, but in some individuals, GCM may present as sudden cardiac death. Herein, we present a fatal case of GCM in a 36-year-old male with a history of autoimmune disorders. The decedent presented to the emergency room due to vomiting and was treated for nausea due to suspected dehydration. He was discharged that night and found dead on his bathroom floor the following day. Postmortem examination revealed psoriasis and granulomatous lesions in the lungs consistent with sarcoidosis, further supporting circumstantial evidence existing between GCM and autoimmune disorders. Additionally, this case provides an opportunity to distinguish GCM from the distinct clinical entity of cardiac sarcoidosis (CS), especially in the setting of systemic sarcoidosis. We hope to raise awareness of this rare disease process and its potential to cause sudden cardiac death so that it may be considered in a differential diagnosis as immunosuppression and early cardiac transplantation largely determine the prognosis.

ABSTRACT

Giant cell hepatitis with autoimmune hemolytic anemia (AHA) is a rare disease of infancy characterized by the presence of both Coombs-positive hemolytic anemia and progressive liver disease with giant cell transformation of hepatocytes. Here, we report a case involving a seven-month-old male infant who presented with AHA followed by cholestatic hepatitis. The clinical features included jaundice, pallor, and red urine. Physical examination showed generalized icterus and splenomegaly. The laboratory findings suggested warm-type AHA with cholestatic hepatitis. Liver biopsy revealed giant cell transformation of hepatocytes and moderate lobular inflammation. The patient was successfully treated with four doses of rituximab. Early relapse of hemolytic anemia and hepatitis was observed, which prompted the use of an additional salvage dose of rituximab. He is currently in clinical remission.

ABSTRACT

Abstract Introduction Reactive hyperplastic lesions develop in response to a chronic injury simulating an exuberant tissue repair response. They represent some of the most common oral lesions including inflammatory fibrous hyperplasia, oral pyogenic granuloma, giant cell fibroma, peripheral ossifying fibroma, and peripheral giant cell lesions. Objective The incidence of those lesions was investigated in an oral pathology service, and the clinical characteristics, associated etiological factors, concordance between the clinical and histopathological diagnostic was determined. Methods A total of 2400 patient records were screened from 2006 to 2016. Clinical features were recorded from biopsy reports and patients' files. Results A total of 534 cases of reactive hyperplastic lesions were retrieved and retrospectively studied, representing 22.25% of all diagnoses. The most frequent lesion was inflammatory fibrous hyperplasia (72.09%), followed by oral pyogenic granuloma (11.79%), giant cell fibroma (7.30%), peripheral ossifying fibroma (5.24%), and peripheral giant cell lesions (3.55%). Females were predominantly affected (74.19%), the gingiva and alveolar ridge were the predominant anatomical site (32.89%), and chronic traumatism was presented as the main etiological factor. The age widely ranges from the 1st decade of life to the 7th. Clinically, the reactive hyperplastic lesions consisted of small lesions (0.5-2 cm) and shared a strong likeness in color to the oral mucosa. The concordance between the clinical and histopathological diagnostic was high (82.5%). Conclusion Reactive hyperplastic lesions had a high incidence among oral pathologies. The understanding of their clinical features helps to achieve a clearer clinical and etiological diagnosis, and the knowledge of factors related to their development. This may contribute to adequate treatment and positive prognosis.


Resumo Introdução As lesões hiperplásicas reativas se desenvolvem em resposta a uma lesão crônica que estimula uma resposta acentuada de reparo tecidual. Elas representam uma das lesões orais mais comuns, inclusive hiperplasia fibrosa inflamatória, granuloma piogênico oral, fibroma de células gigantes, fibroma periférico ossificante e lesão periférica de células gigantes. Objetivo A incidência dessas lesões foi investigada em um serviço de patologia bucal e as características clínicas, os fatores etiológicos associados e a concordância entre os diagnósticos clínico e histopatológico foram determinados. Método Foram selecionados 2.400 registros de pacientes entre 2006 e 2016. As características clínicas foram registradas a partir de laudos de biópsia e dos prontuários dos pacientes. Resultados Um total de 534 casos de lesões hiperplásicas reativas foram recuperados e retrospectivamente estudados, representando 22,25% de todos os diagnósticos. A lesão mais frequente foi hiperplasia fibrosa inflamatória (72,09%), seguida por granuloma piogênico oral (11,79%), fibroma de células gigantes, (7,30%), fibroma periférico ossificante (5,24%) e lesão periférica de células gigantes (3,55%). O sexo feminino foi predominante (74,19%), a gengiva e a crista alveolar foram o local anatômico predominante (32,89%) e o traumatismo crônico foi demonstrado como o principal fator etiológico. A idade variou desde a 1ª década de vida até a 7ª. Clinicamente, as LHR consistiram em pequenas lesões (0,5 a 2 cm) que apresentaram uma forte semelhança de cor com a mucosa oral. A concordância entre o diagnóstico clínico e histopatológico foi alta (82,5%). Conclusão As lesões hiperplásicas reativas apresentaram alta incidência entre as patologias bucais. A compreensão das características clínicas ajuda na realização de um diagnóstico clínico e etiológico mais claro, bem como determinar os fatores relacionados ao seu desenvolvimento. Dessa forma contribui para um tratamento adequado e um prognóstico positivo.

ABSTRACT

Background: Chronic inflammatory and reactive lesions are tumor­like hyperplasia that are produced in association with chronic local irritation or trauma. These proliferations are painless pedunculated or sessile masses in different colors, from light pink to red. The surface appearance is variable from nonulcerated smooth to ulcerated growth, and they from a few millimeters to several centimeters in size. Common examples in the oral cavity include pyogenic granuloma (PG), epulis, traditional clinical name for gingival reactive proliferations, Irritation fibroma, epulis fissuratum, and giant cell granulomas which could either be of peripheral or central origin.Objective: To describe the pattern of inflammatory and reactive lesions of orofacial region. Materials and Methods: A retrospective study of patients attending the oral and maxillofacial clinic between January 2006 and December 2014 was undertaken. Results: One hundred and twelve patients, comprising 61 (54.5%) males and 51 (45.5%) females were seen over the period of study. Their age ranged from 1 to 80 years with a median age of 26.5 years. PG was the most frequently reported lesion accounting for 32 (28.6%). This was followed by nonspecific chronic inflammation (n = 23; 20.5%), epulis/peripheral giant cell granuloma (n = 13; 11.6%), granulation tissue (n = 10; 8.9%), and central giant cell granuloma, (n = 8; 7.1%). Conclusion: The results of the study show that inflammatory and reactive lesions are common in the study population

ABSTRACT

Giant cell reparative granuloma (GCRG) is a type of non-neoplastic lesion that can be rarely found in clinical practices. Due to the lack of specificity in symptoms, signs and auxiliary examinations, it is likely to be misdiagnosed, and thereby affecting the treatment and prognosis. In July 2018, a GCRG patient who was described with "4 years of hearing loss in the left ear, accompanied by 2 months of preauricular swelling" as the first symptom was admitted in our hospital. Both the HRCT and MRI scans for the temporal bone suggested the presence of tumor at the left lateral skull base, but the nature still needed further examination. Intraoperatively, the tumor was completely removed and repaired locally. Pathological examination confirmed the symptoms as GCRG. Immunohistochemistry showed the expression of CD68 and CD163 in the tumor cells. Postoperatively, the patient recovered well without complications, and had the stitches removed before being discharged on schedule.

ABSTRACT

Peripheral giant cell granuloma (PGCG) is an benign non-neoplastic lesion most commonly occurring in oral cavity but extraoral PGCG is extremely rare. Recently, we experienced a case of an isolated PGCG in the parotid gland in 59-year-old man. FNAB findings and radiologic findings including CT and US were suggestive of Warthin's tumor. Partial parotidectomy was performed. Pathologic findings showed fibrillar connective tissue stroma with spindled, ovoid, and round histiocytes-like cells mixed with uneven multinuclear giant cells, small capillaries, hemorrhage, hemosiderin-laden macrophages, and necrosis which were consistent with giant cell granuloma. We report a case of an PGCG in parotid with a review of literature.

ABSTRACT

Most of temporal arteritis occurs in the older patient over 50 years old, and the histopathologic finding shows a granulomatous inflammation, so this called giant cell arteritis. However, the young patients also present with a nodular lesion in their temple, and juvenile temporal arteritis (JTA) should be considered as one of the differential diagnosis, although it is very rare. For both diagnosis and treatment of JTA, excisional biopsy is essential. The pathologic finding of the temporal artery shows panarteritis with lymphoeosinophilic infiltrates, but no giant cell or granulomatous lesion. JTA is a localized disease with low level of systemic inflammatory marker, so the symptom is usually relieved by excision of affected lesion. Peripheral blood eosinophilia present in some cases of JTA, but its relation with clinical course and prognosis is not yet been known. Herein, we report the case of a 24-year-old man diagnosed with concurrent JTA and hypereosinophilic syndrome. We also reviewed the literature of JTA focusing on the impact of combined peripheral eosinophilia on the course of the disease. Combined peripheral eosinophilia may increase the risk of recurrence of JTA after local treatment such as excision only.

ABSTRACT

Giant cell reparative granuloma (GCRG) is a rare benign bone disease of unknown causes. Trauma is a suspected cause or contributor to the onset of GCRG, of which only a few cases have been reported worldwide. We report a case of temporal bone GCRG in a 4-month-old male newborn, who was born at full term via spontaneous vaginal delivery with recent presentation of right facial palsy. He had a right temporo-occipital craniectomy due to GCRG 1 month earlier. There had been no history of trauma. During the workup of the facial palsy complaint, we identified a lobulated mass in the right temporal bone by computed tomography and magnetic resonance imaging. The mass was mainly in the petrous portion of the temporal bone with extracranial extension through the occipital bone. This was consistent with a GCRG recurrence. The mass was removed via the transcrusal approach, and the final histopathology report confirmed it as recurrent GCRG.

ABSTRACT

BACKGROUND: Juvenile xanthogranuloma is a benign, self-limited disorder that usually occurs in infants and young children. Xanthogranuloma is rare in adults, and therefore studies reporting adult xanthogranuloma are limited. OBJECTIVE: We investigated the clinical, histopathological, and immunohistochemical characteristics of adult xanthogranuloma. METHODS: In this study, we evaluated 20 lesions in 19 patients with adult xanthogranuloma. RESULTS: A male predominance was observed (male : female ratio 1.4 : 1), and the mean age of patients was 35.1±16.3 years (range 15∼66 years), with the peak incidence observed in patients in their 20s. Notably, 65.0% of the lesions developed on the head and neck. The nodular form was more common than the papular form of this condition. Histopathological examination revealed dense monomorphic histiocytic infiltration without lipidization and scattered eosinophils without multinuclear giant cells in 5 lesions (25.0%), foamy histiocytic infiltration with variations of completely developed Touton giant cells in 10 lesions (50.0%), and fibrohistiocytic proliferation in 3 lesions (15.0%). On immunohistochemical examination, histiocytes including giant cells showed positive test results with Factor XIIIa (90.9%), vimentin (100%), and CD68 (100%) and negative test results with CD1a, smooth muscle actin, and S-100 protein stains. Tumor excision was the treatment for choice. CONCLUSION: Adult xanthogranuloma most commonly manifested as the nodular form of the disease on the head and neck of men in their late 20s. Histopathologically, the classic Touton cell-rich stage was most commonly observed, followed by the stage of early predominantly mononuclear infiltration. This was a single-center, small-sized retrospective study; however, we expect the results of this study to contribute to a better understanding of adult xanthogranuloma.
