We report a case of a tumoral calcinosis mimicking the appearance of recurrent osteosarcoma of the left femur and tibia in a 29-year-old woman with a history of osteosarcoma and chronic renal failure. Both processes can appear radiographically and histologically similar. Due to loosening of the orthopedic hardware, our patient underwent surgical revision and biopsy. We review the imaging appear...

INTRODUCTION Tumoral calcinosis is a rare syndrome characterized by massive subcutaneous soft tissues deposits of calcium phosphate near the large joints. The condition has been reported in patients ranging from age 5 months to 83 years (Bostrom et al, 1981; Aprin et al 1986), it usually becomes manifest in the second decade of life (Aprin et al, 1986). Men and non-whites are affected more comm...

The authors describe normal imaging of the meninges and meningeal spaces and MR (magnetic resonance) imaging findings in tumoral and nontumoral diseases. Dural or/and pial enhancement may be related to tumoral, infectious or granulomatous diseases.

BACKGROUND Colocalization analysis of confocal fluorescence and electron microscopy (EM) are important tools to detect the expression of multiple anterior pituitary hormones within the same cell. Heterozygous (Men1+/-) mice developed pituitary tumors, mostly reported somatolactotrophinomas and ACTH secreting pituitary adenomas but also nonfunctioning tumors. The aim of the study was to run immu...

BACKGROUND This study determines the expression of P53 protein and the intensity of immunoreactivity in basal cell carcinoma in comparison with the adjacent nontumoral epidermis in sun-exposed areas of the head and neck regions. The mean age of immunoreactivity in tumoral and adjacent nontumoral epidermis is also determined. METHODS This descriptive-analytical study was performed retrospectiv...

the purpose of the present study was to provide empirical support for the construct of the involvement load hypothesis (ilh ) in an efl context. to fulfill the purpose of the study, 4 intact groups consisting of 126 intermediate-level students participated in this experiment. in order to ensure that the participants were at the same level of english language proficiency, the nelson test was adm...

Levels of mtDNA(4977) deletions (DeltamtDNA(4977)) have been found to be lower in tumors than in adjacent non-tumoral tissues. In 87 cancer patients, DeltamtDNA(4977) was detected by multiplex polymerase chain reaction (PCR) amplification in 43 (49%) of the tumors and in 74 (85%) of the samples of non-tumoral tissues that were adjacent to the tumors. DeltamtDNA(4977) deletions were detected in ...

INTRODUCTION Tumoral calcinosis is an uncommon disorder characterised by the deposition of calcium phosphate in periarticular tissues. The deposits are usually around large joints; but rarely can be found around small joints of hand and feet. CASE REPORT We present the case of 13 year old female with three years history of spontaneous, progressively increasing, painful swellings along right m...
