Some authors have suggested that an early diagnosis can influence the prognosis and that a dermatological examination should be part of the follow-up assessment of cancer patients.…”

“…Cutaneous metastases are uncommon, accounting for only 2% of all skin cancers and less than 10% of all distant metastatic lesions [1][2][3][4][5]. There is a correlation between the frequency of cutaneous metastasis and the type and prevalence of primary cancer, according to age and sex, with breast and lung cancers being the most common, in women and men, respectively [3,6].…”

An Atypical Cutaneous Metastasis in a Case of Clear Cell Renal Carcinoma

“…Frequent clinical manifestations of cutaneous metastasis include painless red nodules and plaques [4]. Ulcers, and pink papules, among several other presentations, including inflammatory, cicatricial, and bullous lesions, have been reported but are not as frequent [4,5]. Blue-colored presenting lesions have been described as a unique presentation of renal cancer, liver cancer, and neuroblastomas [4].…”
