RESUMEN
Chondroblastoma is a rare, benign neoplasm usually located in the epiphyses and apophyses of the long bones in the immature skeleton. Radiologically, these tumors have a classic appearance of a lytic lesion with chondroid matrix surrounded by a thin sclerotic rim. Here, we describe the case of a 5-year-old male who presented with a chondroblastoma unusually located exclusively in the metaphyseal region, which led to an elusive diagnosis. The presence of tumors outlying the traditional location or epidemiological spectrum, along with the potential for histopathological misdiagnosis, can pose a diagnostic and therapeutic challenge for the treating team.
RESUMEN
Se presenta un caso clínico poco frecuente de un quiste óseo aneurismático localizado en el cuboides de un niño de 13 años. Se llegó al diagnóstico mediante la tríada de síntomas, estudios por imágenes (radiografía, resonancia magnética) y anatomía patológica. El tratamiento consistió en el abordaje y curetaje minuciosos dentro de la lesión, el fresado de alta velocidad, la electrocauterización y el relleno con aloinjerto óseo liofilizado con chips cortico-esponjosos. Pese al diagnóstico tardío, la evolución clínica fue favorable con remisión completa de los síntomas y retorno a las actividades deportivas, sin recidiva local. Nivel de Evidencia: IV
A rare clinical case of an aneurysmal bone cyst located at the level of the cuboid in a 13-year-old boy is presented. The diagnosis was reached through clinical evaluation, imaging studies (radiograph-MRI), and a pathological anatomy analysis. Its treatment consisted of thorough intralesional curettage, high speed burring, electrocautery, and filling with lyophilized bone allograft with cortical/cancellous chips. Despite the late diagnosis, we would like to highlight the favorable clinical evolution of the patient, with ad integrum remission of the symptoms and return to his sport activities, without elements of local recurrence. Level of Evidence: IV

Myositis ossificans (MO) is a benign disorder where bone forms within muscles or other soft tissues. This condition usually follows trauma and is rare in pediatric patients. Here we present the case of a 2-year-old male who developed MO of his right elbow without obvious trauma to the area. Imaging of MO in the initial phase is highly unspecific and obtaining tissue samples through a biopsy can render misleading reports. In most cases MO is a self-limited process with complete resolution, however, some cases may present a diagnostic and therapeutic challenge.
RESUMEN
Resumen: Introducción: la displasia fibrosa poliostótica es una patología de muy baja prevalencia, por lo que su diagnóstico pasa desapercibido en la mayoría de los casos. Cuando se asocia a endocrinopatías o a lesiones cutáneas hiperpigmentadas corresponde al síndrome de McCune-Albright. Caso clínico: escolar de 8 años, sexo femenino, que presentó una fractura patológica de fémur izquierdo traumática, en la cual se diagnosticó una displasia fibrosa poliostótica. Por presentarse acompañada de pubertad precoz periférica configura el denominado síndrome de McCune-Albright. El control y tratamiento fue multidisciplinario. El equipo de traumatología realizó osteosíntesis con placa y tornillos de la lesión ósea con evolución a la consolidación en plazos habituales (tres meses). A los seis meses de seguimiento la niña se encuentra sin dolor y sin repercusiones funcionales para la vida diaria. Del punto de vista endocrinológico se realizó tratamiento de su pubertad precoz con inhibidores de la aromatasa con el fin de mejorar su talla final y evitar repercusiones psicológicas y emocionales. En este estudio se analizan características de esta patología y su pronóstico vital y funcional.
Summary: Introduction: polyostotic fibrous dysplasia is a low prevalence disease, and for this reason, it often goes undetected. When associated to endocrinopathies and/or hyperpigmented skin lesions we speak about McCune Albright syndrome. Clinical case: eight-year old school girl who presented pathological fracture of the left femur, which was diagnosed as polyostotic fibrous dysplasia. As it was accompanied by peripheral precocious puberty it constituted an indicative clinical picture of the so-called McCune Albright. Control and treatment were multidisciplinary. The traumatology team performed osteosynthesis with plaques and nails to fix the bone lesion, and evolution consolidated in a regular time frame (3 months). Upon six months follow-up, the girl has no pain and presents no functional repercussion in daily life. From the endocrinological perspective, the girl received precocious puberty treatment with aromatase inhibitors with the purpose of improving her final size and avoid psychological and emotional implications. The study presents the characteristics of this condition, as well as its vital and functional prognosis.
Resumo: Introdução: a displasia fibrosa poliostótica é uma doença de prevalência muito baixa, por isso seu diagnóstico passa despercebido na maioria dos casos. Quando associada a endocrinopatias e / ou lesões cutâneas hiperpigmentadas, corresponde à síndrome de McCune Albright. Caso clínico: estudante do sexo feminino, 8 anos, com quadro de fratura patológica traumática do fêmur esquerdo, com diagnóstico de displasia fibrosa poliostótica. Por estar acompanhada de puberdade precoce periférica, configura a chamada síndrome de McCune Albright. O controle e o tratamento foram multidisciplinares. A equipe de trauma realizou osteossíntese de placa e parafuso da lesão óssea com progressão à consolidação nos prazos usuais (3 meses). Aos 6 meses de seguimento, a paciente não apresenta dor e tampouco repercussões funcionais no dia a dia. Do ponto de vista endocrinológico, sua puberdade precoce foi tratada com inibidores da aromatase para melhorar sua altura final e evitar repercussões psicológicas e emocionais. Este estudo analisa as características desta patologia, seu prognóstico vital e funcional.
