Carcinoma renal metastásico de localización atípica. Revisión de la literatura

Abstract

Renal cell carcinoma represents about 3% of all adult malignancy neoplasms. Its metastatic sites, in order of frequency, are lung, bone and liver, whether synchronic or methacronic. Its location, clinical features, onset, evolution and prognosis is very variable. Individualized diagnostic and therapeutic approach, according to prognostic factors. The knowledge of this atypical sites in patients with renal cell carcinoma in the past can lead us to an earlier diagnosis and treatment which could change the evolution of the illness.

Maxillofacial metastasis of genitourinary origin. A report of 3 cases and review of the literature

“…As in our patients, these other cases all appeared synchronically or metachronically with the primary tumour and, depending on the case, with great clinical variation (2,3,7). High vascularisation of the tumour is associated with a high risk of bleeding, either spontaneously or when taking the biopsy.…”

“…Head and neck metastasis of CCRC has been described in the brain, hypophysis, orbit, nasal fossa, ethmoids, oral cavity (gingival), larynx, thyroids and scalp (2,3,5,6). As in our patients, these other cases all appeared synchronically or metachronically with the primary tumour and, depending on the case, with great clinical variation (2,3,7).…”

“…CCRC is considered one of the most surprising tumours, due to its highly vascularised explosive growth, with few or no regional symptoms, and which can be associated with synchronic metastasis as the initial manifestation of the disease in distant organs, as occurs in one third of all cases, or metachronic metastasis that can appear many years after nephrectomy for a primary tumour. In order of frequency, this can occur in tumours of the lung, bone, liver, suprarenal gland and brain (2,3). …”

Metástasis en la mama de carcinoma renal. Reporte de caso

“…Ante la presencia de una lesión con las características descritas, se sugiere la correlación entre ecografía, mamografía y tomografía siempre que sea posible 9 . En pacientes con neoplasias conocidas se debe considerar la presencia de metástasis mamarias incluso cuando se imponen hallazgos clínicos y radiológicos benignos 10 , por lo que el abordaje diagnóstico terapéutico debe ser siempre individualizado 11 .…”
