Defects in mitochondrial enzymes predispose to severe developmental defects as well as tumorigenesis. Heterozygous germline mutations in the nuclear gene encoding fumarate hydratase (FH), an enzyme catalyzing the hydration of fumarate in the Krebs tricarboxylic acid cycle, cause hereditary
A case of a non-functioning ovarian fibroma with extensive calcification in a young Ugandan female is described. Ovarian fibromas occasionally may be bilateral and associated with benign ascites and pleural effusion called Meigs' syndrome or related to a rare hereditary condition known as Gorlin's
A case of infantile digital fibromatosis was studied by light and electron microscopy histochemistry. Using two different acidic solutions of phosphotungstic acid at varying pHs, the round inclusions characteristic of this tumor were shown to have a high protein content with little or no
The final decade of the century confirms the importance of latest generation progestogens in terms of decreased risks associated with the use of doses of ethinyl estradiol of 50 gamma or more, equally effective in contraception of this type. These new combination very considerably limit the untoward
In human fallopian tubes, secretory cells made up about 70% and ciliated cells most of the remainder of the epithelium. At the light microscopic level, lectin-peroxidase conjugates and other methods demonstrated on secretory cells a surface glycocalyx containing glycoconjugates with fucose residues,
Meigs' syndrome (MS), a rare complication of benign ovarian tumors, is easily misdiagnosed as ovarian cancer (OC). We retrospectively reviewed the clinical laboratory data of patients diagnosed with MS from 2009 to 2018. Serum carbohydrate antigen 125 and HE4 levels were higher in the MS group than
There were carried out substrate- and enzymhistochemical reactions of the typical nasopharyngeal angiofibroma in 6 cases. In the environs of the vessels there were mainly neutral mucopolysaccharides, in the left intercellular substance and in the fibroblasts and most cells acid carbohydrates were
