A rare case of bilateral primary malignant lymphoma of breast in a 76 year old woman is presented. The lesion was examined by electron microscopy and immunochemistry. The diagnosis of primary malignant lymphoma remains a diagnosis by exclusion and requires extensive work-up to exclude widespread malignant process. The behaviour of this malignancy tends to be an aggressive one and the prognosis ...
A large series of cases of malignant choroidal melanoma has been reviewed. Certain risk factors have been related to prognosis by means of actuarial life tables. With information from these tables to calculate mortality rates graphs were drawn for various risk factors to demonstrate the differing pattern in tumours of varying size, degree of pigment, position of anterior border, etc. Further, a...
Comparison of Choroidal Thickness in Psoriasis and Control Groups Using Optical Coherence Tomography
Background and Objective: One of the most common extracutaneous complications in psoriasis patients is ocular complications, which is controversial concerning its effect on choroidal thickness. This study aimed to compare the psoriasis patients with healthy individuals in terms of the thickness of the choroidal layer using the optical coherence tomography technique. Materials and Methods: In t...
A patient with S#{233}zary syndrome presented with disease limited to the skin and circulating abnormal lymphocytes but subsequently developed a diffuse undifferentiated lymphoma. Malignant cells from a lymph node effaced with the morphologically undifferentiated lymphoma were characterized as being of thymus-derived (T cell) origin. We have previously shown that circulating malignant lymphocyt...
BACKGROUND Immune suppressant medications such as thiopurines and anti-tumor necrosis factor agents are important for maintaining disease control in most patients with inflammatory bowel diseases (IBDs); however, their use has been associated with the development of malignant lymphoma. The purpose of this Dutch nationwide study was to estimate the relative risk of malignant lymphoma in IBD pati...
Introduction: Malignant lymphoma is divided into two subgroups of Hodgkin's and non-Hodgkin's, and 40% of them occur in areas other than the lymph node, the most common being the digestive tract. According to studies, in recent years the prevalence of non-Hodgkin's lymphomas has increased over the past. Therefore, in this study, we investigated the gastrointestinal lymphoma and the survival rat...
This is the first report of an amelanotic melanoma arising in the unpigmented choroid of a tyrosinase-positive oculocutaneous albino (TPOCA). Melanosomes within the tumour showed a maturation arrest in the unpigmented type II (premelanosome) phase. Other neural crest derived melanocytes in iris and choroid showed similar limited melanogenesis. The neuroectodermally derived melanocytes of the ir...
Thyroid lymphoproliferative disorder is known to be associated with Hashimoto thyroiditis. The major histological types of thyroid disorders are malignant lymphoma, such as diffuse large B cell extranodal marginal zone lymphoma mucosa-associated lymphoid tissue (MALT), and follicular lymphoma. All these lymphomas; however, T represent only a minority cases. Since rarely develops heterogeneous e...
Computed tomography (CT) is currently the most commonly used means for staging malignant lymphoma. 18F-fluoro-2-deoxyglucose positron emission tomography (FDG-PET), FDG-PET/CT fusion, and whole-body magnetic resonance imaging (WB-MRI) are potential alternatives. The purpose of this study was to systematically review published data on the diagnostic performance of CT, FDG-PET, FDG-PET/CT fusion,...
