The skin can host metastatic tumors originating from different organs. We report a case of metastatic renal cell carcinoma to the scalp in a 73-year-old man with features very similar to those of thyroid papillary carcinoma. The histogenesis in relation to its structure is discussed.
INTRODUCTION The kidney is the third primary infraclavicular localization of malignant neoplasms metastasizing to the head and neck. The objective of this paper is to analyze the clinical presentation, diagnostic difficulties, management and outcome of metastatic renal cell carcinoma to the head and neck. MATERIAL AND METHODS Retrospective review of four patients with renal cell carcinoma who...
Granulocyte colony-stimulating factor is a well-known cytokine to stimulate inflammatory cells. We sought to investigate the prognostic value of its expression in patients with non-metastatic clear cell renal cell carcinoma. Enrolled in this study were 228 eligible patients treated with curative nephrectomy for clear cell renal cell carcinoma during 2008. Granulocyte colony-stimulating factor e...
Thyroid carcinoma is an uncommon form of human cancer, with an outstanding overall cure rate. This excellent prognosis is based on the fact that well over 99% of thyroid cancers are primary tumors. Metastatic cancer to the thyroid remains very rare. We report a case of clear cell renal carcinoma metastatic to the thyroid gland 23 years after nephrectomy.
Two cases of renal cell carcinoma, both of which underwent extensive spontaneous regression, are reported. The first occurred in a 56 year old man, forming a well circumscribed renal cortical nodule which contained only very occasional foci of viable renal cell carcinoma with areas of hyalinisation and calcification, and with metaplastic ossification. The second lesion was removed from an 82 ye...
The spontaneous regression of metastatic lesions from renal cell carcinoma (RCC) is extremely rare, but may be encountered following cytoreductive treatments. We report a case of a recurrent RCC with multiple metastatic lesions which spontaneously regressed after undergoing radiofrequency ablation of the renal tumor.
A 75-year-old male patient with non-avid radioiodine Hurthle cell carcinoma was evaluated by 99m Tc- octreotide scintigraphy, in order to find possible metastatic lesions. A bony metastatic lesion was detected by this procedure which was confirmed by histopathology.99mTc-octreotide scintigraphy is a precise and cost-effective imaging modality for detection of non-iodine av...
Meaningful progress has been realized in the treatment of metastatic renal cell carcinoma with the recent approval of a number of new agents; more new agents are on the horizon. Despite the recent completion of many clinical trials that have changed or will change practice, many questions remain. In this manuscript, we highlight the most noteworthy developments in the first- and second-line tre...
Choline is a new PET tracer, which uptake may occur via a choline-specific transporter protein and be accelerated during the proliferation of tumor cells. We report a 61-year-old woman with a metastatic pancreatic tumor from renal cell carcinoma, measuring 35×40 mm. PET scans demonstrated accumulation of 11C-choline in the metastatic pancreatic tumor, but no accumulation of 18F-FDG. Choline PET/...
Renal-cell carcinoma is the most lethal of all urologic malignancies, with a high metastatic potential. Approximately 25% of patients present with stage IV disease, and up to 40% of patients have disease recurrence after nephrectomy. Computed tomography (CT) is an important imaging modality for initial diagnosis and restaging of this patient population. Although extremely rare, clear-cell renal...
