Renal cell carcinoma is the most common type of renal malignancy and it originates from the renal tubular epithelium. Due to the diversity in the histopathological and molecular characteristics, it is typically subclassified into five different categories. Papillary renal cell carcinoma is one subclassification and it includes two variants: sporadic and hereditary. Although the hereditary form ...

Approximately 15% of renal cell carcinomas metastasize to the head and neck region. Here in, we report a rare case patient who underwent nephrectomy for carcinoma (RCC) ten years ago presented with metastatic on her lower lip. A 65-year-old woman rapidly growing mass Pathology resulted in metastasis. Although is uncommon, metastasis should be considered differential diagnosis vascular lesion ar...

BACKGROUND Acquired cystic kidney disease (ACKD) is a widely known renal cell carcinoma risk factor. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS An ultrasound screening of the native kidneys in all renal transplant patients of a renal outpatient clinic who received a transplant between 1970 and 1998 and presented between 1997 and 2003 (n = 916) was initiated prospectively. A total of 561 ...

Renal transplantation increases the probability of malignant tumors by about 2-4-fold overall with a much higher rate for renal epithelial malignancy. Renal tumors in renal transplant recipients are commonly conventional clear cell or papillary renal cell carcinoma. Clear cell papillary renal cell carcinoma is a recently described unique renal epithelial neoplasm with scant eosinophilic or mode...

Classification The major morphological classifications (WHO/ AFIP; modified Mainz classification, and the Heidelberg classification) discriminate eight sub-types of renal cell tumors related to the basic cell types of the nephron from which they are derived, and in line with the genetic facts as presently understood: 1) metanephric adenoma and metanephric adenofibroma, 2) papillary adenoma, 3) ...

background and objective: cutaneous cytology is the study of scraping or smears obtained from skin lesions. although not commonly employed, cutaneous cytology has been a useful tool for clinicians due to simplified procedures and high sensitivity and specificity of presurgical clinical diagnosis of common types of skin tumors. this investigation was conducted to study usefulness of cutaneous cy...

intraosseous squamous cell carcinoma is a rare type of squamous cell carcinoma that requires accurate and early diagnose which is important due to its invasive feature. this article presents a rare case report on intraosseous carcinoma in a 33-year-old patient. the case was a 33-year-old man who was referred to oral disease department of babol college of dentistry complaining of chin pain. in t...
