Abstract
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.

Keywords:
Intraocular biopsy
Intraocular tumor
Vitrectomy
Choroidal melanoma
Cytology
Resumen
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 25G. 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.
