OBJECTIVES To determine the incidence of carcinoma of the uterine cervix and its relationship to schistosomiasis infection. METHODS A retrospective analysis of a 10-year period (1980-1990) at the department of histopathology (cancer registry) of the University of Dar es Salaam using statistical evaluation of the proportional rate of histomorphological(More)
Progressively transformed germinal centers occurred in about 3.5% of cases of chronic nonspecific lymphadenitis. They are larger than germinal centers and are composed of follicular mantle lymphocytes, small clusters of proliferating mainly medium-sized B- and T-cells, as well as an extensive network of follicular dendritic cells. Sixty-six patients with(More)
Intraosseous lipoma is rare and often misdiagnosed. A patient with intraosseous lipoma in the calcaneus is presented with conventional radiography, bone scintigraphy, magnetic resonance imaging and histological findings. The intention of this work is to show the diagnostic procedure of a rare bone tumor. Despite its benign nature, the tumor is often(More)
OBJECTIVES To determine the presence of human papillomaviruses (HPVs) in cervical cancer among patients in Tanzania and to ascertain their prevalence in cases associated with schistosomiasis. METHODS In situ hybridization was applied to 31 carcinomas of the uterine cervix including 10 in which schistosomiasis co-occurred. Twenty-six cases in this series(More)
Using cytochemical, electron microscopic and immunohistochemical techniques in 20 primary malignant lymphomas of the stomach, we found 18 B-cell and 2 T-cell lymphomas. Primary T-cell lymphoma in the stomach has not been previously reported. The T cells in both cases were reminiscent of T immunoblasts with prominent nucleoli and a basophilic cytoplasm. Case(More)
BACKGROUND Since the introduction of mAb, immunohistochemistry has become an important tool in research and in surgical pathology. The most widely used fixative in routine histopathology is formaldehyde, and it has become the gold standard for morphologic tissue preservation. Although the molecular mechanism underlying the tissue fixation is not well(More)
This study aimed to explore the molecular mechanism in tumor invasion and metastasis. The expression of matrix metalloproteinase-2, -9 (MMP-2, MMP-9), tissue inhibitor-1 of matrix metalloproteinase (TIMP-1), cell adhesion molecule 44 variant 6 (CD44v6), HER2/neu and p53 was investigated in 154 patients with head and neck squamous cell carcinoma (SCC) by ABC(More)
