ABSTRACT

El tumor pardo, también conocido como osteoclastoma ó como osteítis fibrosa quística, es un tumor lítico, que se presenta en hiperparatiroidismo (primario, secundario y terciario), aunque su presentación habitual es altamente invasiva, no tiene potencial de malignidad. Los tumores pardos en la mano son muy poco frecuentes y existen solo algunos reportes de casos. Presentamos un paciente masculino de 18 años con una tumoración dura, no móvil, adherida a planos profundos en región dorsal de la mano derecha sobre el cuarto metacarpiano, que además limita la flexión y extensión del cuarto dedo sin alterar su función neurovascular. El paciente fue sometido a resección de la tumoración que involucraba por completo al cuarto metacarpiano derecho, además se realizó un abordaje lateral directo en miembro pelvico izquierdo para tomar un injerto autólogo de peroné no vascularizado. Es importante la detección temprana de este tipo de tumores y se debe dar un adecuado seguimiento, ya que, al progresar, generan una destrucción ósea importante y el tratamiento se vuelve de mayor complejidad. En etapas tempranas, el manejo agresivo con resección y aporte óseo puede evitar secuelas funcionales. El uso de injerto no vascularizado de peroné de seis centímetros para la sustitución del cuarto metacarpiano por osteolísis secundaria a un tumor pardo es una alternativa adecuada de tratamiento que permite la preservación estético funcional de la mano.


The brown tumour, also known as osteoclastoma, or as osteitis fibrosa cystica, is a lytic tumour, which occurs in hyperparathyroidism (primary, secondary, and tertiary), although its usual presentation is highly invasive, has no potential for malignancy. Brown tumours of the hand are sporadic, and there are only few case reports. The case is presented of an 18-year-old male patient with a solid, non-mobile tumour, adhered to deep planes, in the dorsal region of the right hand over the fourth metacarpal. This also limited the flexion and extension of the fourth finger, but did not show alterations in the neurovascular function of the finger. The patient underwent a tumour resection that completely involved the right fourth metacarpal. A direct lateral approach was made in the left pelvic limb to perform a non-vascularised autologous fibular graft. Early detection of this type of tumour is important, and an adequate follow-up must be carried out, since when they progress, they generate significant bone destruction and the treatment becomes more complex. In early stages, aggressive management of resection and bone support can prevent functional sequelae.

ABSTRACT

CONTEXT AND OBJECTIVE: Patients with end stage renal disease (ESRD) and secondary hyperparathyroidism (HPT2) are prone to develop heterotopic calcifications and severe bone disease. Determination of the sites most commonly affected would decrease costs and patients' exposure to X-ray radiation. The aim here was to determine which skeletal sites produce most radiographic findings, in order to evaluate hemodialysis patients with HPT2, and to describe the most prevalent radiographic findings. DESIGN AND SETTING: This study was cross-sectional, conducted in one center, the Hospital Universitário Clementino Fraga Filho (HUCFF), in Rio de Janeiro, Brazil. METHODS: Whole-body radiographs were obtained from 73 chronic hemodialysis patients with indications for parathyroidectomy due to severe HPT2. The regions studied were the skull, hands, wrists, clavicles, thoracic and lumbar column, long bones and pelvis. All the radiographs were analyzed by the same two radiologists, with great experience in bone disease interpretation. RESULTS: The most common abnormality was subperiosteal bone resorption, mostly at the phalanges and distal clavicles (94 percent of patients, each). "Rugger jersey spine" sign was found in 27 percent. Pathological fractures and deformities were seen in 27 percent and 33 percent, respectively. Calcifications were presented in 80 percent, mostly at the forearm fistula (42 percent), abdominal aorta and lower limb arteries (35 percent each). Brown tumors were present in 37 percent of the patients, mostly on the face and lower limbs (9 percent each). CONCLUSION: The greatest prevalence of bone findings were found on radiographs of the hands, wrists, lateral view of the thoracic and lumbar columns and femurs. The most prevalent findings were bone resorption and ectopic calcifications.


CONTEXTO E OBJETIVO: Pacientes com hiperparatireoidismo secundário (HPT2) à insuficiência renal crônica são propensos a desenvolver calcificações ectópicas e grave doença óssea. A determinação dos sítios mais revelantes pode diminuir o custo e a exposição do paciente a radiação desnecessária. O objetivo foi determinar quais locais radiológicos apresentam mais achados radiográficos para avaliar o HPT2 em pacientes em hemodiálise, assim como os achados mais prevalentes. TIPO DE ESTUDO E LOCAL: Estudo transversal, realizado no Hospital Universitário Clementino Fraga Filho (HUCFF), no Rio de Janeiro, Brasil. MÉTODOS: Radiografias de corpo inteiro foram obtidas de 73 pacientes em hemodiálise crônica que tiveram indicação de paratireoidectomia devido a HPT2 grave. As regiões estudadas foram crânio, mãos e punhos, clavículas, coluna torácica e lombar, ossos longos e pélvis. Todas as imagens foram analisadas pelos mesmos dois radiologistas, com grande experiência na interpretação de doenças do osso. RESULTADOS: A alteração mais comum foi reabsorção óssea subperiosteal, principalmente nas falanges distais e clavículas (ambos em 94 por cento de pacientes). Sinal de "rugger jersey" foi descoberto em 27 por cento. Fratura patológica e deformidades foram visualizadas em 27 por cento e 33 por cento, respectivamente. As calcificações foram encontradas em 80 por cento dos pacientes, principalmente na fístula de antebraço (42 por cento), aorta abdominal e artérias dos membros inferiores (ambos 35 por cento). Tumores marrons estavam presentes em 37 por cento dos pacientes, principalmente na face e nos membros inferiores (ambos 9 por cento). CONCLUSÃO: As radiografias com achados mais prevalentes foram mãos e punhos, radiografia lateral da coluna torácica e lombar e fêmur. Os achados mais prevalentes foram reabsorção óssea e calcificação ectópica.

ABSTRACT

El tumor pardo es una forma localizada de osteítis fibrosa quística, parte del compromiso óseo por hiperparatiroidismo. Como primera expresión de hiperparatiroidismo es infrecuente, debido a que actualmente éste se diagnostica en estadios asintomáticos o mínimamente sintomáticos. Presentamos el caso de una paciente con un tumor pardo localizado en el maxilar superior izquierdo, como primera manifestación de hiperparatiroidismo primario causado por un adenoma paratiroideo. Posterior a la realización de una paratiroidectomía el tumor evolucionó con franca regresión, sin necesidad de ningún otro procedimiento quirúrgico local.


Brown tumor is a localized form of osteitis fibrosa cystica, being part of the hyperparathyroid bone disease. It rarely is the first manifestation of hyperparathyroidism, since nowadays, the diagnosis is made at an asymptomatic or minimally symptomatic stage. We present a case of a left superior maxillar brown tumor as the first manifestation of primary hyperparathyroidism due to a parathyroid adenoma. A parathyroidectomy was performed, and there was a regression of the bone lesion, without the need of performing other local surgical procedures.

ABSTRACT

Adenomas of the parathyroid gland, the majority of which are of the solitary chief cell type, are the most frequent cause of primary hyperparathyroidism (pHPT). Parathyroid adenomas composed predominantly or exclusively of oxyphil cells are rare and most oxyphil cell adenomas of this organ remain clinically silent. We present here a case of hyperfunctioning oxyphil cell adenoma of the parathyroid gland resulting in pHPT, osteitis fibrosa cystica and simultaneous bilateral fractures upper shafts of femora.

ABSTRACT

Brown tumor (BT) is an uncommon condition that represents the terminal stage of the cystic osteitis fibrosa and have been increasingly reported in hyperparathyroidism secondary to renal failure, due to the increase of survival in patient with hemodialysis. The fine needle aspiration diagnosis is of great importance in the recognition of the BT, although it can be difficult to distinguish it of lesions as the aneurysmal bone cyst and giant-cell tumor. We describe the case of 20-year-old female with chronic renal failure undergoing hemodialysis during six years. Both x-rays and computer tomography revealed a tumor in head of right humerus and lytic images in scapula of the same side, clavicles and ribs. The patient was subjected to a fine needle aspiration biopsy of the tumor of humerus head and the sample was processed with the habitual technique of inclusion in paraffin and stained with hematoxilina and eosina. Histological preparations showed several multinucleate giant cells and spindly or fibrillary cells, feature that was pointed out as compatible, in a context of secondary hyperparathyroidism to chronic renal failure, with a BT. We consider that the radiological and tomographyc finds, besides the history of chronic renal failure with a long history of hemodialysis, were enough to link, with great approach, the histopathology with the diagnosis of BT.


El tumor pardo (TP) es una condición infrecuente que representa la fase terminal de la osteítis fibrosa quistica, habiéndose incrementado los reportes de tumores pardos en hiperparatiroidismos secundarios a falla renal. debido al aumento de supervivencia en pacientes dializados. El diagnóstico por aspiración con aguja fina es de gran importancia en el reconocimiento del TP. aunque puede ser dificil distinguirlo de lesiones como el quiste óseo aneurismático y el tumor de células gigantes. Presentamos el caso de una mujer de 20 años con insuficiencia renal crónica dializada durante seis años. que mostraba, con la tomografia computada y radiografia, un tumor en cabeza de húmero derecho e imágenes osteolíticas en homóplato homolateral, clavícula y costillas. Se realizó una biopsia por punción de la tumor ación de cabeza de húmero y la muestra fue procesada con la técnica habitual de inclusión en parafina y tinción con hematoxilina y eosina. Los preparados histológicos mostraron tejido constituido por abundantes células fusiformes y numerosas células gigantes multinucleadas, cuadro histopatológico que se señaló como compatible, en un contexto de hiperparatiroidismo secundario a insuficiencia renal crónica, con un TP.

ABSTRACT

El hiperparatiroidismo primario actualmente es diagnostico en etapa más precoz predominando la presentación asintomática. Las formas sintomáticas son variadas destacando entre ellas el compromiso renal y óseo. Este último puede abarcar desde alteraciones radiológicas mínimas, hasta el grado máximo de compromiso representado por la osteitis fibroquística. Esta es actualmente una manifestación poco frecuente del hiperparatiroidismo primario, pudiendo en raras ocasiones complicarse con fracturas patológicas. Debido a la rareza de este cuadro se presentan dos casos de pacientes con fracturas patológicas debidas a hiperparatiroidismo primario y se discuten algunos aspectos de esta rara e interesante enfermedad

ABSTRACT

Presentamos dos pacientes con hiperparatiroidismo primario, en quienes un diagnóstico tardío por falta de apreciación clínica y paraclínica de sus antecedentes, los hace evolucionar a una manifestación ósea severa. Probablemente por la misma lesión ósea tan avanzada encontramos hiperparatiroidismo primario con normacalcemia prolongada
