<p>My colleague shared this interesting case with me regarding a lesion on the upper back of a young woman that had become a little itchy but had not otherwise changed. What is the diagnosis, which can be <strong>firmed up</strong> clinically?</p>
<p>Derrmoscopically there is a homogenous pink background, on which are foci of grouped white clods (arrows). </p>
<p>The lesion is a dermatofibroma with areas of sebaceous gland hyperplasia (SGH). While dermoscopically the lesion is not an obvious dermatofibroma, clinically there was a regular <strong>firm</strong> lump under the skin, and the lesion dimpled in the centre when squeezed. </p>
<p>In the literature there are case reports of dermatofibromas with areas of SGH, especially on the upper trunk. This was the first such case I had seen, until two weeks later when along came the second!</p>
