RESUMO
STUDY DESIGN: Case report. OBJECTIVE: To report the clinical and imaging findings of a patient with the extremely rare association of aneurysmal bone cyst and osteoblastoma in the cervical spine. To our knowledge, only three cases have been reported in the published literature in children under 16 years of age with this condition in the cervical spine. METHODS: The patient's history, physical examination, imaging findings, and management with a complete 4-year medical history, surgical intervention and radiological follow-up are reported. RESULTS: A 4-year 11-month-old boy was diagnosed with aneurysmal bone cyst in association of osteoblastoma and was treated with CT-guided intralesional injection calcitonin and methylprednisolone. During the course of intralesional therapy, a pathological fracture of C2 was produced. Subsequently, a widened intralesional excision and instrumented fusion from occiput to cervical spine (C0-C4) was performed. CONCLUSION: The association of aneurysmal bone cyst and osteoblastoma in spine is extremely rare. Although both are benign lesions, in the cervical location, complete removal of the tumors is challenging. Wide resection with reconstruction of the segments for stability associated with adjuvant treatment with calcitonin and corticosteroids provides a good option.

Resumen: Introducción: El osteoblastoma es un tumor osteoblástico benigno, agresivo y poco frecuente. Su localización más frecuente es en elementos posteriores de la columna vertebral y el sacro. La presentación en cuboides es excepcional. Caso clínico: Masculino de 50 años que inició padecimiento en 2005, con dolor y aumento de volumen en región dorsolateral del mediopié. En las radiografías se observa injerto óseo y una lesión en cuboides, radiotransparente, heterogénea, multilobulada, con bordes irregulares que sobrepasa la cortical lateral. Se realizó angiotomografía donde se observó la lesión hipervascularizada; en la gammagrafía se observó captación del tecnecio 99 y en la resonancia magnética se reporta una lesión con cambios postquirúrgicos, quística, multilobulada. Se tomó biopsia transquirúrgica con abundante tejido fibroconectivo, osteoblastos, nidos de tejido osteoide e hipervascularidad del estroma, aumento de celularidad sin atipias y escasas células gigantes multinucleadas. Se clasificó Enneking 2. Se inició tratamiento con resección y curetaje del tumor, crioterapia y colocación de injerto tricortical en el defecto óseo. Mostró buena evolución postquirúrgica. A los tres años del procedimiento quirúrgico se encuentra sin datos de actividad tumoral y asintomático. A pesar de que el osteoblastoma no se presenta de forma habitual en cuboides, debe tomarse en cuenta como diagnóstico diferencial. Conclusión: Los tumores óseos, a pesar de tener localizaciones habituales, pueden presentarse en zonas poco frecuentes y por lo tanto, el estudio completo clínico radiográfico e histopatológico en cada paciente es fundamental.
Abstract: Introduction: Osteoblastoma is a benign, aggressive and rare osteoblastic tumor. Its most common location is in later elements of the spine and sacrum. The cuboid presentation is exceptional. Case report: A 50-year-old male who began her condition in 2005, with pain and increased volume in the dorsolateral region of the middle foot. X-rays show bone grafting and a cuboid lesion, radiotransparent, heterogeneous, multilobed, with irregular edges that exceeds the lateral cortical. Angiotomography was performed where hypervascularized injury was observed; bone scan showed uptake of technetium 99, and MRI reported an injury with post-surgical, cystic and multilobed changes. Trans surgical biopsy was taken, increased atypia-free cellularity and few multinucleated giant cells were reported and Enneking 2 qualified. Treatment was initiated with resection of the tumor, cryotherapy, and placement of tricortical graft in the bone defect. He exhibited good post-surgical evolution. At three years of the surgical procedure, he`s without tumor and asymptomatic. Although osteoblastoma does not usually occur in cuboid, it should be taken into account as a differential diagnosis. Conclusion: Bone tumors, despite having common locations, can occur in rare areas and therefore the complete radiographic and histopathological clinical study in each patient is critical.

El osteosarcoma "tipo osteoblastoma", una variante menos agresiva del osteosarcoma, es una enfermedad poco frecuente y representa un desafío diagnóstico tanto clínico como histopatológico. Se han publicado escasos reportes de casos de este tumor. Presentamos a un paciente de 16 años con un osteosarcoma "tipo osteoblastoma" localizado en la columna cervical. La biopsia ósea bajo tomografía reveló una lesión con un patrón de crecimiento permeativo, con sospecha de osteosarcoma "tipo osteoblastoma". Se realizó una espondilectomía total en bloque mediante un doble abordaje. Se describen el caso clínico, la secuencia diagnóstica, la técnica quirúrgica y el seguimiento a 10 años. Nivel de Evidencia: IV
Osteoblastoma-like osteosarcoma, a less aggressive variant of osteosarcoma, is a rare tumor which presents a clinical and histopathological diagnostic challenge. We have found few reports of cases of this tumor in the literature. In this case, we describe an osteoblastoma-like osteosarcoma of the cervical spine in a 16-year-old patient. CT-guided bone biopsy showed a lesion with a permeated growth pattern, which led to the suspicion of an osteoblastoma-like osteosarcoma. A total en bloc spondylectomy was performed through a dual approach. We present the clinical case, the diagnostic sequence, the surgical technique and 10-year follow-up results. Level of Evidence: IV

Se presenta el caso de un paciente de 31 años de edad, en cuya radiografía simple de tórax se observó una radiopacidad en la zona del quinto arco costal izquierdo y con localización posterior. Se realizaron exámenes complementarios hematológicos e imagenológicos para determinar las características morfológicas de dicho hallazgo. Fue intervenido quirúrgicamente y se realizó la exéresis de dicho tumor. Los resultados anatomopatológicos arrojaron la presencia de un osteoblastoma, con afectación de un solo arco costal posterior. Los tumores de la pared costal, y especialmente los benignos, son poco frecuentes, por lo cual se decidió presentar este caso y los aspectos más relevantes y actuales respecto a esta variedad de tumores(AU)
The case of a 31-year-old female patient, with simple chest X-ray in which it was observed a radioopacity in the zone of the left fifth costal arch with posterior localization was presented. Hematological and imaging complementary tests were made to determine the morphological characteristics of this finding. She was operated on and an exeresis was performed. The anatomopathological results showed the presence of an osteoblastoma with affectation of just one posterior costal arch. The tumors of the costal wall and, specially, the benign are uncommon. Therefore, it was decided to present this case and the most important and current aspects on this variety of tumor(AU)

The purpose of this article is to present a case of phalanx osteoblastoma. We will start by saying that osteoblastoma is rare, it accounts for 1% of primary bone tumors; it is most frequent in the posterior spine, and is very unusual in the phalanges. Early diagnosis is desirable due to its similarity, mainly radiologic, with other entities that result in similar bone lesions. Clinical case. We present the case of a 39-year-old male who presented with swelling of the proximal phalanx of the 5th digit of the left hand that began one year before. The histopathologic study of the tumor lesion showed that it was composed of prominent osteoblasts. No mitoses were observed. Enblock surgical resection of the lesion and curettage were performed.
