ABSTRACT
Caso clínico: Ninguna técnica de biopsia intraocular es inocua y todas tienen posibilidad de falsos negativos por la dificultad para obtener una muestra suficiente. Paciente con sospecha de melanoma tras biopsia negativa con vitrectomía 25 G. Se realiza biopsia coriorretiniana modificada en la que además de extraerse un fragmento mediante cirugía bimanual, se obtiene material de la lesión con vitreotomo para realizar citología, confirmando el diagnóstico de sospecha de melanoma de coroides. Discusión: La asociación de una citología obtenida con vitreotomo de una lesión coroidea asociada a la escisión de un fragmento de la lesión puede mejorar la eficacia de la biopsia intraocular (AU)
Clinical case: No intraocular biopsy technique is free of risk and all have the possibility of giving false negatives due to the difficulty in obtaining a sufficient sample. A modified chorioretinal biopsy was performed on a patient with suspected choroidal melanoma after negative biopsy with 25G vitrectomy. In addition to removing a solid fragment of tumor material using bimanual surgery, material from the lesion was obtained with the vitreotome to perform cytology, which confirmed the diagnosis of melanoma. Discussion: Cytology obtained through the vitreotome in association with removing a solid sample of the choroidal lesion may improve the efficiency of intraocular biopsy (AU)

To our knowledge the case which is reported is the seventh glomus tumor described so far. The mass was located in the ethmoidal cavity and a spreading to the nasal cavity and choana. Firstly, the patient was supposed to have a polyposis naso-sinusal due to the symptom. After being operated (maxillo-ethmoidectomy trans-sinusal technique) the light and electron microscopic descriptions of the mass which was excised, showed the real diagnosis "glomus tumor". The patient stopped coming to the controls one month after the first operation. He did not consult us until eight months later. It was found by TC a recurrence of the tumor. The patient did not complain of any symptoms. He was operated again (external ethmoidectomy technique) and the mass was completely removed. Eventually, the think that it is very important to distinguish the "glomus tumor" (the one which has just been described) from the non-chromaffin paraganglioma or chemodectoma.
