Non-Hodgkin diffuse large B-cell lymphomas of the mastoid that extend from the nasopharynx are extremely rare in children. Moreover, in lymphoproliferative diseases, the presence of otoneurological signs prior to systemic disease involvement is rare. Here, we present a rare case of non-Hodgkin B-cell lymphoma invading the middle ear and mastoid in a 1-year-old boy that mimicked acute mastoiditi...

The purpose is to report an unusual case of orbital non-Hodgkin lymphoma. A 75-year-old man presented with bilateral chronic epiphora complaint and inferior eyelid tumors, axial proptosis, without previous systemic manifestation. The patient was submitted to bilateral endonasal dacryocystorhinostomy twice and the epiphora complaint persisted. The inferior eyelid and bone marrow biopsy revealed ...

Ocular annexes lymphomas are malignancies which occur in the conjunctiva, eyelids, lacrimal gland and orbit. Ocular annexes lymphoma is primarily a disease of older adults, with a slight female preponderance. Most lymphomas are low-grade B-cell lymphomas, with marginal zone lymphoma being by far the most common type. Marginal zone lymphoma typically involves the ocular annexes primarily, wherea...

Many studies have researched the prognostic factors of Hodgkin disease. Up date, seven most important prognostic factors have been defined. Among them, as an important negative prognostic factor, the dissemination of the disease at the moment of diagnosis stands out. The aim of this study was to determine the influence of the presence of mediastinal mass greater than a third of the chest diamet...

background and objectives: human herpes 6 virus (hhv-6) could remain latent and chronic in the host cells after primary infection. hhv-6 genome encodes certain trans activation proteins which may results in development of malignantlymphoma. the association of human herpes six virus (hhv-6) infection and hodgkin and non-hodgkin lymphomas is strongly supported by epidemiological studies. the aim ...

INTRODUCTION Breast lymphoma, either as a manifestation of primary extranodal disease or as secondary involvement, is a rare malignancy, and its diagnosis, prognosis, and treatment have not been clearly defined. On the other hand, Vacuum-assisted breast biopsy (VABB) is a minimally invasive technique with ever-growing use for the diagnosis of mammographically detected, non-palpable breast lesio...

Abstract Background Malignant lymphoma accounts for nearly 20% of all mediastinal neoplasms in adults and 50% children. Hodgkin’s disease is the most common primary lymphoma. In non-Hodgkin’s lymphoma, two forms are lymphoblastic diffuse large B-cell The aim this study to implement diffusion MRI algorithm diagnosis differentiating Hodgkin's from non-Hodgkin's assessment post therapeutic respons...
