non-hodgkin lymphoma (nhl) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. we report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal nhl without central nervous system or systemic involvement. a ...

Primary intraocular lymphoma is almost always a central nervous system B-cell non-Hodgkin lymphoma. Primary intraocular lymphoma is commonly diagnosed by demonstrating lymphoma cells in the vitreous or cerebrospinal fluid. An interleukin (IL) 10 to IL-6 ratio greater than 1.0 in these fluids and the detection of immunoglobulin gene rearrangement are useful adjuncts in the diagnosis of primary i...

Ocular involvement in lymphoma is a relatively rare condition that can result from a primary intraocular lymphoma or an intraocular manifestation of systemic lymphoma. Lymphoma manifestations frequently masquerade as other more benign intraocular conditions including allergic or infectious conjunctivitis, uveitis, multiple evanescent white dot syndrome, acute retinal necrosis, or herpetic retin...

protein losing enteropathy (ple) as an initial finding of lymphoma, is extremely rare in childhood. we describe clinical and pathological features of an unusual case of gastrointestinal lymphoma presented with ple as a sole manifestation. differential diagnosis in children presenting with ple is critical because early diagnosis and treatment are important for survival in patients with lymphoma.

Intraocular involvement of T-cell lymphoma is rare. We report a case presented with inflammatory glaucoma, neurotrophic keratopathy, and choroidal detachment. An 81-year-old man presented with unilateral high intraocular pressure and keratic precipitates. Polymerase chain reaction of the aqueous humor was negative for herpes simplex virus type 1 and 2, varicella zoster virus, and cytomegaloviru...

Non-Hodgkin lymphoma (NHL) is one of the masquerade syndromes of malignant melanoma that can occur with two main patterns of presentations in the eye: metastatic involvement of uveal tract, and primary involvement of retina. We report ophthalmic, imaging and histopathological findings in the first case diagnosed as primary choroidal NHL without central nervous system or systemic involvement. A ...

156 iranian patients with primary malignant tumors of the small intestine were reviewed. malignant lymphoma was the most common tumor type, comprising 128 patients (82%), followed by adenocarcinoma (22 patients, 14.1 %), leiomyosarcoma (4 patients, 2.56%) and carcinoid tumor (2 patients, 1.28%). lymphomas and adenocarcinomas were primarily located in the duodenum or jejunum, whereas leiomyosarc...

postmortem examination of a 5.5-year-old holstein cow with history of sudden death showed a veryhuge spleen (120 × 45 × 10 cm) associated with severe haemoperitoneum. histopathological findingsincluded extensive infiltration of medium to large sized lymphocytic and lymphoblastic cells with smallamounts of cytoplasm, round nuclei with coarsely granular chromatin in the spleen, and limited foci o...

Primary intraocular lymphoma (PIOL) is a subset of primary central nervous system (CNS) lymphoma which initially presents in the eye with or without simultaneous CNS involvement (1). It is considered a variant of extranodal, non-Hodgkin lymphoma that is usually of an aggressive diffuse large B cell type (1–3). Diagnosis of PIOL requires histopathologic evidence of malignant lymphoma cells in br...

IMPORTANCE Intraocular lymphomas represent a diverse group of hematologic malignant neoplasms involving different tissues within the eye. Predominant involvement of the retina and vitreous without uveal infiltration in systemic lymphoma, mimicking a primary vitreoretinal lymphoma, is extremely rare. Our study emphasizes the importance of systemic evaluation in addition to central nervous system...
