MENA ESTEVEZ, Hiram Luis et al. Bilateral Conjunctival MALT Lymphoma in an Adolescent. CCM [online]. 2014, vol.18, n.1, pp.141-148. ISSN 1560-4381.

The primary MALT lymphomas of the conjunctiva are uncommon, the conjunctival affection is less frequent, and its bilaterality is uncommon, representing 5% of all extranodal non- Hodgkin lymphomas. Low-grade B lymphomas derived from marginal zone lymphocytes with molecular alterations are those that have blocked its apoptosis. A 12 -year- old patient with primary MALT type lymphoma of the lower tarsal conjunctiva of both eyes was presented in this paper. The patient was healthy and presented redness and discomfort in both eyes in a year of evolution. The physical examination showed discrete ptosis of the left eye of a millimeter. Mass of orange - salmon color in lower conjunctival sac of both eyes, not adhered to deep planes was observed. Orbital X-ray and cranial CT were unaltered. Complete hematology, coagulation tests, and all elemental analytical biochemistry were performed, the results were normal. The pathological study reported: dense and extensive infiltrate lymphoid, composed of small lymphocytes, some without nucleolus plasmacytoid appearance without indentation, these data suggested a malignant lymphoid proliferation. The diagnosis of low-grade B-cell lymphoma of MALT type was confirmed.
