RESUMO
Osteoid osteoma is a benign bone tumour; its main symptom is pain, which is sometimes resistant to analgesic or anti-inflammatory medication. The surgical treatment consists of en bloc excision or curettage of the lesion. Several alternative methods have been proposed, among which CT guided-percutaneous radiofrequency ablation. We report on ten patients who were diagnosed clinically and radiologically as presenting an osteoid osteoma and were treated with this technique, with more than two years follow-up. Results were uniformly excellent. The pain was relieved and the rate of post-operative complications was very low. We recommend percutaneous CT-guided radiofrequency ablation for the treatment of this lesion.

OBJECTIVES: To report a new case of bilateral synchronic testicular tumors, and to perform a bibliographic review on the topic, emphasizing the ultrasound characteristics and oddity of these presentation, which accounts for less than 1% of germ cell testicular tumors. METHODS/RESULTS: 29-year-old patient consulting because of an increase of the testicular size over one year. Physical examination and ultrasound revealed a synchronic neoplastic involvement of the testicles, suggesting the radiological diagnosis of bilateral "seminomatous tumor", with "non seminomatous" foci in one of them. Histologically, tumors were in accordance with ultrasound working diagnosis (seminomas, showing one of them anaplastic foci). CONCLUSIONS: Synchronic testicular involvement by neoplasias is an unfrequent fact, scarcely reported in the literature, being most cases germ cell tumors, mainly seminomas, and shows a good correlation between ultrasound and histologic diagnosis.

OBJECTIVES: To report a case of synchronic neoplasia--chromophobe renal cell carcinoma and low grade non Hodgkin lymphoma--in a 38-year-old male patient, because, although association of these two neoplasias is known, the fact of renal neoplasia being a chromophobe carcinoma is rarely referred to in medical bibliography (3 cases described after Med-Line search). METHODS/RESULTS: The diagnostic study included ultrasound and CT scan in a patient presenting with in non specific abdominal symptoms and neck adenopathy; patient underwent left radical nephrectomy and excision of neck adenopathy. Histologic and immuno-histochemical studies revealed the coexistence of chromophobe type renal cell carcinoma and diffuse centrocytic lymphoma. CONCLUSIONS: Column in the association between chromophobe histological type renal cell carcinoma and non Hodgkin lymphoma is very rare. Presence of these two tumors in the same patient may pose problems for clinical staging, prognostic predictions, and treatment. Then, due to the fact that it is not usual and that a local stage renal carcinoma presents with neck adenopathies, when they appear possible coexistence of these tumors should be suspected.

OBJETIVO: Comunicar un caso de diagnóstico neoplásico sincrónico: carcinoma renal de tipo cromófobo y linfoma no Hodgkin de bajo grado, en un paciente varón de 38 años de edad, ya que, aunque la asociación de estas dos neoplasias es conocida, el que la neoplasia renal corresponda a un carcinoma de tipo cromófobo es un hecho escasamente referido en la literatura (3 casos descritos, según búsqueda bibliográfica Med-Line). MÉTODOS/RESULTADOS: El estudio diagnóstico se realizó mediante ecografía y tomografía, en un paciente con clínica abdominal inespecífica y adenopatías cervicales, practicándose posteriormente una nefrectomía radical izquierda y la resección de una adenopatía cervical. El estudio histológico e inmunohistoquímico correspondiente puso de manifiesto la coexistencia de un carcinoma renal de tipo "cromófobo" y un linfoma centrocítico difuso. CONCLUSIONES: La asociación entre el carcinoma renal subtipo histológico cromófobo y el linfoma no Hodgkin es muy infrecuente. La presencia de estos dos tumores en un mismo paciente puede plantear problemas de estadiaje, predicción pronóstica y tratamiento. Por tanto, dado que no es habitual que un carcinoma renal en estadio local presente adenopatías cervicales, en estos casos debería sospecharse esta posible coexistencia (AU)
