abstract primary cardiac tumors are rare in all ages. their reported prevalence ranges from 0.001 to 0.03 percent in autopsy series. 25 percent of primary cardiac tumors are considered to be malignant, the majority of which are sarcomas. on account of the late presentation of symptoms in malignant heart masses, finding locally infiltrative tumors or systemically widespread cases at initial pres...

background: salivary gland tumors are relatively uncommon and they consist of 3-10% of head and neck neoplasms. most of studies have shown geographic variation in the incidence and histopathologic types of salivary gland neoplasms. the aim of this study was to evaluate the salivary gland tumors in isfahan for 10 years duration. materials and methods: in this epidemiological study, 229 medical r...

Nuclear ubiquitous casein and cyclin-dependent kinases substrate (NUCKS) is a chromosomal protein of unknown function. Its amino acid composition and structure of its DNA binding domain resemble those of high mobility group A (HMGA) proteins which are associated with various malignancies. Since changes in expression of HMGA are considered as a marker of tumor progression, it is possible that si...

Adult male rats were irradiated with single, whole-body doses of X-rays (430 or 680 rads) or with neutrons (230 or 320 rads) and maintained in a duration-of-life study. An analysis of the extent of tumorigenesis was made according to the type of tumor, the number of animals with tumors, and the distribution of tumors among organs for each dose group. Greater proportions of the irradiated groups...

Background: Neonatal tumors are usually prenatally diagnosed or within the irst 30 days of life. The true incidence ofneonatal tumors is unknown as a great number of pregnancies with a prenatally diagnosed mass result in stillbirth ormiscarriage. Most solid neonatal tumors are benign whereas less than 50% of neonatal neoplasms are malignant;however, some tumors with malignant ...

The use of dermoscopy has offered a new morphological dimension of skin lesions and has provided an effective diagnostic tool to differentiate melanoma from other benign or malignant skin tumors but also to support the clinical diagnosis in general dermatology. The aim of this article is to provide an overview of the most recent and important advances in the rising world of dermoscopy.

Abstract Cutaneous lesions, especially skin tumors in dogs, are among the most common lesions this animal species. The aim of study was to identify types canine cutaneous determine absolute and relative frequency each type lesion, anatomical locations, mean age, as well gender breed distribution. examination included all samples dogs obtained by surgical biopsy veterinary clinics examined at La...

Merkel cell carcinomas (MCCs) are uncommon, highly malignant skin tumors that develop in sun-exposed areas of the skin. Most of the MCCs are CK 20-positive and CK 7-negative such as our case. About 80% of Merkel cell carcinoma is associated with Merkel cell polyomavirus.

Malignant melanoma is known for its wide range of histologic patterns and its ability to mimic other malignant tumors. Malignant melanoma is generated in the skin and sinus paranasalis by a malignant tumor of melanocytic origin. Malignant melanoma is usually quickly diagnosed by the presence of melanin granules. On the other hand, amelanotic melanoma is without melanin granules and is often dif...

Glomus tumors are usually benign tumors that occur in the skin and soft tissues of the extremities. Visceral locations, such as stomach, intestines or lung, are extremely rare because glomus bodies are rare or absent in these organs. This report describes our experience in a 47-year-old woman diagnosed with a peritoneal malignant glomus tumor. This finding has not been previously reported.
