We report a case of primary bilateral mucosa associated lymphoid tissue (MALT) lymphoma of the lacrimal sac. MALT lymphoma is a subtype of Non-Hodgkin’s Lymphoma of the ocular adnexa. When the primary site of the lymphoma is the lacrimal sac, it mimics chronic dacryocystitis. This may delay diagnosis, with potentially lethal results.
Primary bilateral and symmetric MALT lymphoma of the lacrimal sac mimicking chronic dacryocystitis
Evolução comparativa da ceratocone no olho com implante de anel intraestromal em relação ao olho contralateral não operado. Quando o ceratocone do olho não operado evolui e passa a apresentar valores piores que o olho que recebeu o anel, este valor é marcado pela cor vermelha.
