Resumo
An inedited case in the Brazilian literature of conjunctival fibrous histiocytoma
discovered during a wide scale community project accomplished by the team
of the Center of Reference in Ophthalmology of the Hospital das Clínicas da
Universidade Federal de Goiás in the Amazon region is reported. A 38 year-old
caucasian woman presented with a vascularized lesion on the medial portion
of the bulbar conjunctiva and caruncular region of the right eye with extension
for the limbus and invading about 2 mm of the medial cornea resembling a
pterygium. Pathologic findings revealed that the lesion was constituted by
spindle-shaped cells, with storiform arrangement, and large histocytelike cells.
The immunohistochemistry revealed strong positivity for vimentin and the
neoplastic cells were negative for AE1/AE3, HMB 45, S 100 protein. The histopathologic
diagnosis was fibrous histiocytoma. The evolution demonstrated the
tumoral growth and the possibility of a malignant lesion.
