Conjunctival Pediatric Follicular Lymphoma: Case Report and Literature Review.

Follicular lymphoma (FL) is the second most commonly reported B-cell lymphoma and accounts for 6% of all orbital lymphomas. FL presentation in the pediatric population is rare. This study reported an 18-year-old male with a pink elevated lesion in the conjunctiva of the left eye and normal ocular parameters. Following a complete excisional biopsy, the lesion was oval and smooth grossly and showed dense proliferation with a high nuclear-cytoplasmic ratio microscopically. Immunohistochemical studies revealed positive CD20 and bcl-6 while bcl-2 was negative, which is a common feature for pediatric FL in contrast to bcl-2 positivity found by immunohistochemistry in FL occurring in adult patient population. No signs of recurrence were observed over 2 years of follow-up. This study adds a new case to the existing few reports. Interestingly, all reported cases were males including the patient, mean duration of onset was 5 months, and mean duration of follow-up was 18.4 months. The authors emphasize that total surgical excision with close monitoring is reasonable management of such clinical entity.Follicular lymphoma (FL) is a rare entity in pediatric patients. Six cases have been reported with conjunctival FL in the literature (age between 6 and 21 years). Interestingly, all of them were male including the patient.
