RESUMO

Los tumores cartilaginosos son un grupo amplio y heterogéneo de neoplasias caracterizadas por la presencia de una matriz condroide que presenta crecimiento lobular y patrones de calcificación en arcos y anillos o en palomitas de maíz. En RM destaca su hiperintensidad en las secuencias potenciadas en T2, y en las imágenes poscontraste, un relace lobulado o septal. En la clasificación de 2020 de la OMS, los tumores de estirpe condral se clasifican en benignos, intermedios o malignos. A pesar de los avances tecnológicos, siguen suponiendo un reto tanto para el radiólogo como para el patólogo, siendo la principal dificultad la diferenciación entre los tumores benignos y malignos, razón por la que requieren un abordaje multidisciplinar. Este trabajo recoge los principales cambios introducidos en la actualización de 2020, describe las características de imagen de los principales tumores cartilaginosos y proporciona las claves radiológicas para diferenciar entre tumores benignos y malignos.(AU)


Cartilaginous tumours are a large and heterogeneous group of neoplasms characterised by the presence of a chondroid matrix, with lobular growth and arcuate, ring-like or popcorn-like calcification patterns. MRI shows hyperintensity in T2-weighted sequences and a lobulated or septal relief in postcontrast images. In the WHO 2020 classification, chondral tumours are classified as benign, intermediate or malignant. Despite technological advances, they continue to pose a challenge for both the radiologist and the pathologist, being the main difficulty the differentiation between benign and malignant tumours, which is why they require a multidisciplinary approach. This paper describes the main changes introduced in the 2020 update, describes the imaging characteristics of the main cartilaginous tumours and provides the radiological keys to differentiate between benign and malignant tumours.(AU)

RESUMO

Se presenta el caso clínico de un varón de 17 años con un osteocondroma antero-lateral en fémur distal derecho de cuatro años de evolución tratado mediante exéresis quirúrgica. Utilizando las 14 necesidades de Virginia Henderson se valoró al sujeto tras la cirugía y se elaboró un plan de cuidados identificando los diagnósticos enfermeros según la taxonomía de la North American Nursing Diagnosis Association (NANDA), los resultados según la Nursing Outcomes Classification (NOC) y las intervenciones enfermeras oportunas, siguiendo la Nursing Intervention Classification (NIC). Tras el alta hospitalaria del paciente se realizó un seguimiento durante tres meses. Se observó una evolución favorable destacando la importancia de efectuar una valoración integral de la persona debido a que se vieron afectadas las dimensiones física, psicológica y social, así como la necesidad de emplear una correcta información referente a su patología, con vocabulario comprensible al tratarse de un adolescente


We present the case report of a male 17-year-old patient with anterolateral osteochondroma in right distal femur with 4-year evolution treated through surgical excision. Using the 14-need theory by Virginia Henderson, the patient was assessed after surgery, and a plan of care was prepared identifying nursing diagnoses according to the taxonomy by the North American Nursing Diagnosis Association (NANDA), outcomes according to the Nursing Outcomes Classification (NOC), and the relevant nursing interventions, following the Nursing Intervention Classification (NIC). After the patient was discharged from hospital, there was 3-month follow-up. A favourable evolution was observed, highlighting the importance of conducting a comprehensive assessment of the person, because there was impact on his physical, psychological and social dimensions, as well as the need for adequate information regarding his condition, with terminology easy to understand by an adolescent

RESUMO

Exostosis or osteochondromas are benign bone tumors frequently.These benign tumors may be symptomatic or be manifested on the occasion of a complication. We report the case of a child boy 1O years, admitted to our training multiple exostosis, with a loca-tion iliopubic left that proved by painful induration left of the base of the penis. Induration the increasing volume, it bothered the child during urination. Conventional radiography and CT were in favor of a pedunculated osteochondroma of the left iliac ramus compressing the urethra. The child underwent surgical tumor resection and pathological examination confirmed the diagnosis of osteochondroma. The evolution was good with disappearance of urinary symptoms down two years without recurrence

RESUMO

Objetivo: 1) Recordar la epidemiología y semiología de los osteocondromas del extremo proximal del húmero (EPH); 2) determinar las indicaciones de su tratamiento y 3) hacer recomendaciones relativas al tratamiento quirúrgico en ese asiento. Material y método: Estudio retrospectivo observacional y longitudinal de 20 osteocondromas solitarios y 12 múltiples del EPH. Se analizaron las características epidemiológicas, clínicas y de imagen de los pacientes de la serie, y los resultados del tratamiento, con un tiempo medio de seguimiento de los casos intervenidos de 45 meses. Resultados: Los osteocondromas solitarios correspondieron a 11 hombres (55%) y 9 mujeres (45%), con una edad media de 21 años. Doce (60%) fueron intervenidos a una edad media de 23 años por ser sintomáticos o, en un caso, por sospecharse malignización. Dos casos solitarios no intervenidos pudieron haber involucionado espontáneamente. Las formas múltiples ocurrieron en 11 hombres (92%) y una mujer (8%) y 3 fueron intervenidos. No hubo complicaciones ni recidivas y el resultado funcional fue excelente en todos los pacientes. Discusión: Los osteocondromas del EPH son relativamente frecuentes, aunque la mayoría de las publicaciones son de casos clínicos aislados o de series cortas. Conclusiones: Los osteocondromas del EPH no difieren de los de otra localización. Los casos sintomáticos y en los que se sospecha malignización serían intervenidos, aquellos mejor con el crecimiento finalizado. El tratamiento quirúrgico se resume en la planificación del abordaje mediante TC o RM, resección en bloque extraperióstica y una eventual reconstrucción ósea, idealmente con homoinjerto


Objective: 1) To recall the epidemiology and signs of osteochondromas of the proximal humerus (OPH); 2) determine treatment indications; 3) and make recommendations for surgical treatment. Methods: Retrospective, observational and longitudinal study of 20 solitary and 12 multiple osteochondromas of the proximal humerus. We analyzed the epidemiological, clinical and imaging characteristics and treatment results with an average time of follow-up of the operated cases of 45 months.Results: Eleven (55%) males and 9(45%) females with an average age of 21 years presented solitary osteochondromas. Twelve (60%) cases were operated on at a mean age of 23 years because they were symptomatic or, in one case, malignancy was suspected. Two solitary osteochondromas could have spontaneously regressed. Multiple osteochondromas were found in 11(92%) males and one (8%) female of whom 3required surgery. There were no complications or recurrences. Functional outcome was excellent in all patients. Discussion: Osteochondromas of the proximal humerus are relatively common, although most publications are case reports or short series. Conclusions: Osteochondromas of the proximal humerus do not differ from those in other locations. Symptomatic cases and those in which malignancy is suspected would be operated, the former preferably at the end of growth. The surgical treatment is summarized in planning the approach, using CT and/or MRI, extraperiosteal en bloc resection, and eventual bone reconstruction, ideally with allograft

RESUMO

Presentamos el caso clínico de un varón de 30 años que presentaba un osteocondroma a nivel del cuello femoral, una localización poco habitual de asentamiento de este tipo de tumores. A pesar de ser un tumor relativamente frecuente, nuestro objetivo es describir las principales características de diferentes lesiones óseas, sean o no de origen tumoral, independientemente de que se descubran de manera casual o a raíz de un síntoma, como el dolor articular en este caso (AU)


We present the case of a 30-year-old male with an osteochondroma at the femoral neck, an unusual location for this type of tumor. In spite of being a relatively frequent tumor, our objective is to describe the main characteristics of different bone lesions, whether they are tumor-derived or not, regardless of whether they are discovered incidentally or due to a symptom, such as joint pain in this case (AU)

RESUMO

El condrosarcoma es un tumor óseo maligno de origen cartilaginoso. Es el tercero en frecuencia de los tumores óseos malignos, solo superado por el mieloma múltiple y el osteosarcoma. El 75% son lesiones primarias y el 25% restante pertenecen a categorías especiales, entre las que se cuentan las variantes anatomopatológicas y las formas secundarias. Un condrosarcoma secundario es aquel que aparece en una lesión cartilaginosa benigna preexistente, entre las que se incluyen el osteocondroma solitario, la osteocondromatosis múltiple, el encondroma, las diferentes encondromatosis y la condromatosis sinovial primaria. La incidencia de la transformación maligna es muy variable en función del tipo de lesión. En este trabajo se discuten e ilustran las diferentes formas de condrosarcomas secundarios, poniendo un especial énfasis en los hallazgos radiológicos que deben alertar y que permiten al radiólogo tener un papel central en el diagnóstico, manejo y seguimiento de estos pacientes (AU)


Chondrosarcomas are malignant bone tumors originating in cartilage. Chondrosarcoma is the third most common malignant bone tumor after multiple myeloma and osteosarcoma. About 75% of chondrosarcomas are primary lesions. The remaining 25% belong to special categories such as histologic variants and secondary forms. A secondary chondrosarcoma is one that appears in a pre-existing benign chondral lesion; the different types of secondary chondrosarcomas include solitary osteochondroma, multiple osteochondromatosis, enchondroma, the different types of enchondromatosis, and primary synovial chondromatosis. The incidence of this malignant transformation varies widely in function of the type of lesion. In this article, we discuss and illustrate the different types of secondary chondrosarcomas, placing special emphasis on the imaging findings that should alert to these lesions and give radiologists a key role in the diagnosis, management, and follow-up of these patients (AU)

RESUMO

PURPUSE: Chondrosarcoma is a malignant bone tumor with poor prognosis. Surgical treatment is the first choice for chondrosarcomas. Chondrosarcoma is not sensitive to chemotherapy and radiotherapy. Identification of biological markers is important for the early diagnosis and targeted treatment of chondrosarcoma. This study investigated the protein expression and clinicopathological significance of ROR2 and FRAT1 in 59 chondrosarcomas and 33 osteochondromas. METHODS: ROR2 and FRAT1 protein expression in tissues was measured by immunohistochemistry. RESULTS: The percentage of positive ROR2 and FRAT1 expression was significantly higher in patients with chondrosarcoma than in patients with osteochondroma (P < 0.01). The percentage of positive ROR2 and FRAT1 expression was significantly lower in patients with histological grade I, AJCC stage I/II stage, Enneking stage I, non-metastatic and invasive chondrosarcoma than patients with histological grade III, AJCC stage III/IV, Enneking stage II + III, metastatic and invasive chondrosarcoma (P < 0.05 or P < 0.01). ROR2 expression was positively correlated with FRAT1 expression in chondrosarcoma. Kaplan-Meier survival analysis demonstrated that histological grade, AJCC stage, Enneking stage, metastasis, invasion, and ROR2 and FRAT1 expression significantly correlated with a short mean survival time of patients with chondrosarcoma (P < 0.05 or P < 0.01). Cox multivariate analysis showed that positive ROR2 and FRAT1 expression was an independent prognostic factor that negatively correlated with postoperative survival and positively correlated with mortality. CONCLUSIONS: Positive ROR2 and FRAT1 expression is associated with the progression and poor prognosis of chondrosarcoma

RESUMO

El osteocondroma es uno de los tumores óseos más frecuentes, representando el 40 % de los tumores de hueso. En la mano supone el 20 % de los tumores óseos, a pesar de que sólo el 1 % de los osteocondromas se ubica a este nivel. Existen dos teorías respecto a su origen: una que indica que se debe a un defecto del crecimiento fisario y otra que defiende su naturaleza tumoral. Algunos autores recomiendan no tratarlo; sin embargo, se debe extirpar cuando produce sintomatología. Presentamos un caso clínico de osteocondroma gigante en la segunda falange del segundo dedo de la mano derecha de una paciente de 2 años de edad, con deformidad severa y alteraciones funcionales. Realizamos escisión mediante escoplo y curetaje medular con cucharilla y reconstrucción con material osteoconductor, con resultado satisfactorio (AU)


The osteochondroma is one of the most common bone tumours, raising a 40 % of them. It reaches a 20 % of bone hand tumours, although only 1 % of osteochondromas appear at the hand. There are two theories that try to explain its origin; one explaining that it consists on a physis growing defect, and other one defending a tumoral nature. Some authors recommend not treating them; however, when appear sintomatology should be removed. We present a clinical case of a giant ostechondroma at the second phalanx of the second finger of the right hand in a 2 years old patient, with deformity and functional alteration. We made tumoral excision by chisel and medullar curettage with satisfactory result (AU)
