OBJECTIVE Follicular dendritic cells (FDCs) and interdigitating dendritic cells (IDCs) are dendritic cells found in lymphoid follicles, reactive follicles and in lymphomas. The goal of this study was to evaluate the presence and distribution of FDCs and IDCs in oral lymphomas. MATERIAL AND METHODS Immunohistochemistry reactions were applied to 50 oral lymphomas using the antibodies anti-CD21,...

OBJECTIVES Non-Hodgkin lymphomas are malignant neoplastic proliferations of the immune system that can manifest as nodal or extranodal lymphomas. The aim of this study was to retrospectively investigate the site of occurrence of lymphomas in the head and neck area and to analyze the typical symptoms of patients who presented at an oral and maxillofacial surgical department. MATERIAL AND METHO...

Expression of prolactin and of prolactin and estrogen receptors in lymphocytes, bone marrow, and lymphoma cell lines suggests that hormonal modulation may influence lymphoma risk. Prolactin and estrogen promote the proliferation and survival of B cells, factors that may increase non-Hodgkin lymphoma risk, and effects of estrogen may be modified by catechol-O-methyltransferase (COMT), an enzyme ...

INTRODUCTION Oral lesions have been recognised as prominent features of acquired immune deficiency syndrome (AIDS) and human immunodeficiency virus (HIV) infection since the beginning of the epidemic. OBJECTIVE This descriptive study was conducted to study the types of oral lesions among HIV-infected patients in Singapore. MATERIALS AND METHODS Oral examination was done on 81 randomly selec...

lymphomas are solid malignant tumors having a wide spectrum of clinical and pathological features. non-hodgkin’s lymphoma (nhl) is a subtype of lymphoma with two-thirds of the cases presenting as lymph node enlargement. the remaining one third of nhl cases has been reported in the extranodal sites, including the gastro intestinal tract, waldeyer’s ring, bone, skin, and brain. intraoral non-hodg...

Oral plasmablastic lymphoma (PBL) is a rare malignancy, associated with HIV or other immunocompromised conditions. The lesion constituted a new subtype of diffuse large B-cell lymphoma and proposed a distinct entity based on its basic morphology, its clinical behaviour involving predominantly extramedullary sites (particularly oral cavity), and its limited antigenic phenotype data suggesting pl...

Acquired ichthyosis (AI) is a reactive cutaneous manifestation that can be associated with malignant hematological disease, including cutaneous T-cell lymphoma (CTCL). Since it is difficult to distinguish AI from ichthyosiform mycosis fungoides, to select the treatment for CTCL with ichthyosis-like appearance and to evaluate its efficacy is sometimes challenging. In this report, we describe a c...

RATIONALE Plasmablastic lymphoma (PBL) is a rare subtype of human immunodeficiency virus (HIV)-related non-Hodgkin's lymphoma that predominantly manifests in the oral cavity. PATIENT CONCERNS Three cases of HIV-negative PBL were reported. DIAGNOSES HIV-negative PBL INTERVENTIONS:: The patient had undergone chemotherapy. OUTCOMES Clinical outcomes were very poor in Cases 1 and 3; Case 2, w...
