Backgrounds/aims: The authors describe the case of a 79-year-old Caucasian woman who presented an ocular adnexal lesion as the first clinical manifestation of a systemic follicular lymphoma, highlighting the clinicopathological features of this rare entity and its potential to be misdiagnosed as marginal zone lymphoma of the mucosa-associated lymphoid tissue.
Methods: Conjunctival impression cytology was performed for a rapid initial diagnosis of lymphoma, and subsequent histopathological and immunohistochemical studies were carried out for its confirmation and to identify the best therapeutic regimen.
Results: After the initial presentation and diagnosis, she was submitted to complete clinical evaluation; confluent retroperitoneal lymphadenopathy was detected through abdominal computed tomography, characterizing clinical stage III.
Purpose: This study was designed to evaluate the use of human amniotic membrane for ocular surface reconstruction after conjunctival squamous cell carcinoma resection.
Methods: Amniotic membrane was obtained at the time of cesarean section and was preserved at -80 masculineC in glycerol and cornea culture media at a ratio of 1:1. The inclusion criteria were patients presenting proliferating lesions suggestive of squamous cell carcinoma (flat or elevated white lesions resembling "fish meat") that involve the conjunctiva, limbus and cornea.
Purpose: To evaluate the surgical outcome of preserved amniotic membrane transplantation (AMT) for ocular surface reconstruction in chemical burn with limbal stem cell deficiency.
Design: Prospective, noncomparative, interventional case series.
Participants: Twenty eyes of 20 consecutive patients with limbal stem cell deficiency secondary to ocular chemical injury.
