¿Cuerpo extraño o tumor ocular? Presentación de un caso.

The case of a 15-year-old female patient is presented, whose main complaint was the sensation of a foreign body and increased volume of dark coloration in the right eyeball. Personal history of trauma not reported. On physical examination, an elongated, dark mass with regular edges and hard on palpation was found below the bulbar conjunctiva. Surgical treatment was performed and a subconjunctival foreign body compatible with the tip of a pencil was removed, encompassed at its distal end by a dark, fibrovascular tissue with metallic luster. Some considerations that could be the explanation for the tissue behavior adjacent to the foreign body are exposed. Due to its unusual nature, the presentation of the case was decided.
