Diffuse infiltrating retinoblastoma.

Clinical Presentation and Genetic Paradigm of Diffuse Infiltrating Retinoblastoma: A Review.

Retinoblastoma is the most common childhood cancer. Thanks to modern technology and good medical access, mortality in Europe has decreased to about 5%. Diffuse infiltrating retinoblastoma is a very rare subtype of this neoplasm and is characterized by its atypical growth pattern. Diffuse infiltrating retinoblastoma may mimic other more innocuous diseases and may therefore be misdiagnosed. The p...

Sonographic, CT, and MR imaging findings in diffuse infiltrative retinoblastoma: report of two cases with histologic comparison.

SUMMARY Diffuse infiltrating retinoblastoma is a rare form of retinoblastoma. We report two cases of this disease in which sonographic, CT, and MR imaging findings were compared with histologic studies obtained after enucleation. Although nonspecific, MR imaging provides valuable morphologic data for the diagnosis of diffuse infiltrating retinoblastoma and may help in decisions regarding enucle...

Diffuse infiltrating retinoblastoma invading subarachnoid space

We report herein an unusual case of diffuse infiltrating retinoblastoma involving the brain, which caused a patient's death 27 months after enucleation. An eight-year-old boy complained of blurred vision in his right eye (OD) in October 2006. Funduscopic examination showed optic disc swelling, dense whitish vitreous opacity, and an orange-colored subretinal elevated lesion adjacent to the optic...

Immunohistochemical evaluation of lymphocyte types infiltrate into the canine seminomas

BACKGROUNDS: Seminoma is frequently observed in human and canine testes especially in cryptorchids. Canine and human seminomas are typically associated with leukocytic infiltration. OBJECTIVES: We aimed to identify the type of lymphocytes that infiltrate to seminomas. METHODS: Tumor infiltrating lymphocytes were evaluated by immunohistological techniques in 5 dogs with diffuse seminoma. Routine...
