PURPOSE Natural killer (NK) cell neoplasm is a rare disease that follows an acute course and has a poor prognosis. It usually emerges from the nose and appears in the ocular tissue as a metastasis. Herein, we describe a case of NK-cell neoplasm in which the eye was considered to be the primary organ. CASE A 50-year-old female displayed bilateral anterior chamber cells, vitreous opacity, bullo...

primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of b-cell origin. the association of anaplastic lymphoma kinase (alk) negative anaplastic large cell lymphoma (alcl), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...

A case of primary malignant non-Hodgkin's lymphoma of the breast is reported. This is the first well-documented case of breast lymphoma in our institution and also in Iran. The diagnosis of primary breast lymphoma requires the presence of lymphomatous infiltration in close ass, tissue in patients with neither previous lymphoma nor concurrent lymphoma in another site. There is no definite cl...

Purpose To report a rare case of secondary intraocular lymphoma treated with intravitreal rituximab, following pars plana vitrectomy. Observations A 74-year-old female with history of parotid gland large B-cell lymphoma presented bilateral intraocular recurrence 10 years after the onset of the primary malignancy. Systemic work-up including PET/CT Scan, bone marrow biopsy, brain MRI and CSF an...

  Primary Hepatic Lymphoma (PHL) is rare and possibly associated with viral hepatitis and autoimmune diseases. Scleroderma could exceptionally be complicated by lymphoma. We describe PHL occurring in a 52-year-old female suffering scleroderma for eight years, with no history of cytotoxic or high-dose glucocorticoid therapy. CT scan, performed to work-up abdominal discomfort, constipation, and ...

We report a case of intraocular lymphoma in a 65-year-old man, 15 months after cardiac transplantation. On Magnetic Resonance (MR) images, the iris and the anterior chamber of the right eye were found to be involved with an enhancing soft-tissue lesion. To our knowledge, this is the first case of post-transplantation intraocular lymphoma evaluated with MR imaging.

abstract background: primary cardiac lymphoma is extremely rare. case report: in this care report, we present the case of a 46-year-old man with primary cardiac lymphoma involving left atrium and interatrial septum, presenting as dyspnea palpitation and irregular heart beat. the diagnosis was obtained by transthoracic echocardiography and surgical biopsy with subxiphoid approach which revealed ...

Primary central nervous system lymphoma (PCNSL) is an extranodal non-Hodgkin lymphoma involving brain, intraocular structures and spinal cord, without evidence of systemic disease. The majority of PCNSLs are diffuse large B-cell type. We encountered a rare case of primary dural marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) with extension into the brain in a 59-year-old man....

primary adrenal lymphoma is extremely rare. we report a case with primary bilateral adrenal lym-phoma in a young male patient. he presented with abdominal pain and weight loss. pathologic study revealed malignant lymphoma, diffuse large cell type (t- cell origin). patient recieved combination chemotherapy and radiation therapy but 22 months after diagnosis died because of progression of dis ease
