Selection of Oncogenic Mutant Clones in Normal Human Skin Varies with Body Site.

Skin cancer risk varies substantially across the body, yet how this relates to the mutations found in normal skin is unknown. Here we mapped mutant clones in skin from high- and low-risk sites. The density of mutations varied by location.

A rare cutaneous presentation of metastatic parotid adenocarcinoma.

Primary adenocarcinomas of the parotid gland are rare, accounting for < 5% of all head and neck malignant neoplasms. The biological behaviour of these tumours varies considerably. Low-grade tumours are minimally invasive, whereas high-grade tumours show a high incidence of local recurrence and distant metastases.

Multiple eruptive milia in a 9-year-old boy.

We report a 9-year-old boy with a gradual onset of multilobulated cysts on his nose and cheeks and histology in keeping with milia. His presentation was compatible with a diagnosis of multiple eruptive milia. As far as we are aware, this is only the second patient reported.
