for approximately 3% of primary malignant bone tumors and for 5% of extranodal lymphoma (1). In the majority of cases, the tumor involves the extremities and less frequently the axial skeleton. Disseminated malignant lymphoma is extremely rare, representing 0.8% of malignant non-Hodgkin’s lymphoma(NHL) (2). Here, we encountered primary NHL of bone involving the skull, spine, both upper and lowe...

We observed a young woman who showed growth of a choroidal melanoma over the course of 2 pregnancies, with subsequent enucleation of the eye. This is the first such documented case. In addition 4 other women with uveal malignant melanomas presented during pregnancy. This observed number of pregnancies (5) was greater than the expected number (2.1) among women of childbearing age who underwent e...

The case of a 40-year-old female patient with choroidal melanoma with secondary glaucoma presenting as a painful blind right eye is reported. Liver metastasis was detected by ultrasonography. The choroidal tumor measured 2 x 2.1 x 1.5 cm; histopathology showed that it was of the spindle cell (spindle A) variety. Such tumors are rare in non-white races and secondary glaucoma is an uncommon prese...

Cold agglutinin disease (CAD) is a well-recognized complication of lymphoproliferative disorders. It has been previously recognized that cases of primary CAD frequently exhibit underlying malignant lymphoma in the bone marrow. Lymphoplasmacytic lymphoma is the most common subtype of malignant lymphoma; however, diffuse large B-cell lymphoma (DLBCL) has also been documented, albeit extremely rar...

Lymphomas are a heterogenous group of malignant diseases. 30-50% of patients, even before chemo- and radiotherapy are begun have anemia. The pathogenesis of this anemia is multifactorial and still not completely clear. Newer investigations refer to a causality between the anemia in patients with lymphoma and the inappropriate erythropoietin production for the degree of anemia. Based on this fin...

purpose : choroidal melanoma is the most common primary ocular malignancy among the adult population. authors investigated the clinical findings, histopathologic features, types of retinal detachment and the precise anatomic origin of enucleated eyes for primary ocular malignant melanoma in shiraz university of medical sciences (sums) hospitals between 1990 and 2005. methods : this was a cross ...

BACKGROUND Yersinia pseudotuberculosis generally infects the gastrointestinal tract and causes enteropathy symptoms suggesting infection. Y. pseudotuberculosis infections are often complicated with intraceliac lymphoadenopathy mimicking malignant lymphoma. This is a first case of Yersinia pseudotuberculosis enteropathy mimicking enteropathic γδ T-cell lymphoma. This case highlighted the γδ T-ce...

Non-Hodgkin lymphoma (NHL) represents the third most common group of malignant lesions of the oral cavity, following squamous cell carcinomas and salivary gland neoplasms. It accounts for 3-5% of all malignant lesions of the oral cavity [1]. Further, only 1% of all lymphomas are primary oral cavity lymphoma. Non-Hodgkin’s lymphoma of the tongue is extremely rare. It can arise from Waldeyer’s ri...

C ataracts normally occur in the later decades of life, which is also at a time when there is higher incidence of ocular tumors. Before a patient undergoes cataract surgery, it is important that surgeons perform a complete eye examination that includes careful funduscopy. The surgeon must be able to distinguish ocular tumors from other lesions and, should a lesion be identified, send patients f...
