Renal cell carcinoma presenting as an ominous metachronous scalp metastasis

Renal cell carcinoma (RCC) accounts for 3% all of solid organtumours and is slightly more common in men in the age range of
60 to 70 years. Skin metastases occur in 3% to 6% of RCCs. There
are only approximately 30 cases of scalp metastases secondary to
RCC in the literature. They usually occur late in metastatic disease
and are a bad prognostic marker. A 67-year-old Caucasian male
presented with a metastatic scalp lesion, 10 years post-radical
treatment for RCC. His initial diagnosis was a T3bN0M0 RCC.
He presented with a raised erythematous lesion on his parietal
scalp, the histology of which demonstrated late metastatic recurrence.
Shortly after this, he developed diffuse metastatic disease.
Metastatic RCC can occur many years after initial diagnosis and
present in many forms. Cutaneous metastatic lesions of RCC can
mimic many other dermatologic conditions and carries an ominous
prognosis. It is therefore important not only for the urologist, but
also general practitioners and patients to be vigilant of any new
skin lesion as a portent of impending metastatic disease.
