June 2021 | Case of the Month

History

Welcome back to the new look PCDS website, and our first case.

This lady was referred as a 2-week wait with a changing lesion on the right temple.


Examination

Investigations

What are the diagnoses?

Diagnosis

RevealHide the answer

The diagnoses are:

  1. A seborrhoeic keratosis, and
  2. A basal cell carcinoma - dermoscopically we see a gelatinous background, well-focused arborising (branching) vessels and blue-grey clods

There are rare reports of malignant transformation of seborrhoeic keratoses, however, a more likely explanation is perhaps of a collision tumour ie one very common tumour (a seborrhoeic keratosis) arising at the same site as another common tumour (BCC).

This is a case of interest, which should not change your practice - please don't start picking off all seborrhoeic keratosis, unless something is telling you to do otherwise, but do continue to tell patients that seborrhoeic keratoses are harmless and that they don't need to be reviewed even if they grow.
