Conjunctival CD5+ MALT lymphoma

Conjunctival MALT Lymphoma

A 67-year-old woman was referred for staging of a mucosa-associated lymphoid tumor lymphoma involving the left conjunctiva. CT scan had shown paravertebral and pelvic masses, and a breast nodule. FDG PET/CT demonstrated moderately increased uptake in the left ocular conjunctiva and confirmed the paravertebral and pelvic masses and the breast nodule. Moreover, abnormal FDG uptake was shown in 2 ...

Translocation (5; 11) in a conjunctival MALT lymphoma.

Lymphoma is the most frequent malignant tumor of the ocular adnexa with the most common histologic type being extranodal marginal zone B-cell lymphoma (EMZL) of mucosa-associated lymphoid tissue (MALT lymphoma). Here we report a case of a 28 year-old male who presented with a left conjunctival mass of one year duration. A diagnosis of primary MALT lymphoma of the conjunctiva was made based on m...

CD5- mantle cell lymphoma.

Mantle cell lymphoma (MCL) typically expresses B-cell antigens and CD5 and overexpresses bcl-1 protein. However, unusual cases of bcl-1+ and CD5-MCL have been observed, posing a practical challenge for correct diagnosis and management. We identified 25 cases (48 samples) of bcl-1+ and CD5- lymphoma. CD5 expression was assessed by flow cytometric analysis alone (1 case), immunohistochemical anal...

EUS in MALT lymphoma.

Update: gastric MALT lymphoma.

PURPOSE OF REVIEW Gastric MALT lymphoma is a model malignancy for examination of how neoplasia may arise from chronic inflammation. It is also exemplifies the translation of biologic knowledge of a disease towards improved clinical practice. Several recent publications have furthered the understanding of gastric MALT lymphoma pathogenesis, clinical behavior, and treatment. RECENT FINDINGS A s...
