Case Number : Case 2038 - 28 March 2018 Posted By: Uma Sundram

Glandular structures and a fibromuscular band in linear disposition. Omphalomesenteric duct remnant or urachal remnant. Urachal remnant can show transitional, squamous or gut epithelium.

Like Anil’s comment, but my impression is of an apocrine glandular epithelium, as sebaceous structure..like a hidradenitis or something similar or an odd neuroductal/neurofollicular hamartoma...

The last figure appears to show smooth muscles in the dermis. Supernumerary nipple?

Yeahh Anh!  That’s the more appropriate thought. A ductal epithelium with apocrine metaplasia...

There are dilated ducts with scattered bundles of nerve and smooth muscle consistent with accessory Nipple !

Nailed it anh and LR123!

accessory nipple.

This was so characteristic I had to post it! This one has some nice apocrine glands, deeply placed, like the axilla or breast. A good thing to look out for. Also, some nice nerve bundles high in the reticular dermis which would be unusual in totally normal skin. I find the ddx of 'normal skin' most challenging so like to post these things ....

Beautiful!
