BACKGROUND Skin adnexal tumors (SAT) encompass wide spectrum of benign and malignant tumors that differentiate toward one or more adnexal structures found in normal skin. Overall incidence of SATs is low yet they can be challenging to diagnose. AIMS The aim of this study is to study the spectrum and microscopic features of SATs. MATERIALS AND METHODS It was a retrospective cross-sectional, ...

From March 1980 to March 1989 a total number of 2254 (7.6%) new malignant cases from Kerman province were diagnosed by examination of surgical specimens, blood films and bone marrow smears. The crude relative frequency of cancers was studied and compared with other areas of Iran. Gastric (11.36%) and urinary bladder (7.01 %) carcinomas were significantly more common in Kerman province than...

objective: the aim of the present study was to estimate crude and age-standardized incidence rates for oral and pharyngeal nonsquamous cell malignant tumors in kerman province over a period of 11 years. materials and methods: the data used in this retrospective population-based study were extracted from the records registered in all pathology centers of kerman province from 1991 to 2001. all co...

introduction: different imaging modalities are used to evaluate salivary gland diseases, including tumors. ultrasonography (us) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. the aim of this study was to evaluate the role of us in differentiating malignant from benign parotid tumors, in the context of previous controversy...

Malignant phyllodes tumor is a rare tumor of the breast occurring in females usually between the ages of 35 and 55 years. It is often difficult to distinguish benign from malignant phyllodes tumors from other benign entities such as fibroadenomas. This case presentation demonstrates a woman with malignant phyllodes tumor treated with mastectomy with abdominal skin flap reconstruction.

Patients with inflammatory rheumatisms, such as rheumatoid arthritis, are more prone to develop skin cancers than the general population, with an additional increased incidence when receiving TNF blockers. There is therefore a need that physicians treating patients affected with inflammatory rheumatisms with TNF blockers recognize malignant skin lesions, requiring an urgent referral to the derm...

Many types of cancers develop in the oral and maxillofacial region. Squamous cell carcinoma is the most common cancer and constitutes over 90 percent of these tumors. Malignant transformation is a genetic process, which later makes a phenotyping change at the cellular level. Some cancers such as oral squamous cell carcinomas (OSCCs) develop from pre-malignant lesions and conditions. Despite adv...

Primary sacral tumors are rare, accounting for approximately 5–7% of all spinal tumors [1]. Metastases are the most common malignant tumors of the sacrum and can be derived from lung, breast, kidney, prostate, head and neck, gastrointestinal, or skin (melanoma) cancers [2, 3, 62]. Primary benign and malignant tumors of the sacrum may arise from bone or neural elements or the bone marrow in case...

Background: Malignant melanoma is the most aggressive form of skin cancer. In contrast to other tumors, the role of estrogen in the initiation and progression of melanoma remains unclear. The aim of this study was to evaluate estrogen receptor beta protein expression in human melanoma tissues and in the benign melanocytic lesions. Method: Twenty-one patients, 11 with cutaneous melanoma and 10 w...

this study aimed to investigate the frequency of varicella zoster virus (vzv) in benign and malignant breast tumors. a total of 24 carcinomas and 24 fibroadenomas paraffin embedded tumoral tissue samples were obtained from the pathology sections of toos and firoozgar hospitals in tehran, iran. all samples were collected from patients from june 2011 to february 2012. dna was extracted from all s...
