Histology: In common acquired melanocytic nevi, the melanocytes are arranged symmetrically in a lateral fashion. They are arranged in nests. The nested melanocytes do not have the typical dendritic appearance…
Multiple blue nevi can be seen in the Carney complex, also known as the NAME or LAMB syndrome. This complex of clinical findings includes multiple blue nevi, lentigines, ephelides, myxomas,…
Histology: The cysts are lined with a pseudostratified or stratified columnar epithelium. The epithelium can closely approximate the appearance of transitional urethral cell epithelium. The lining surrounds a central cavity…
Treatment: Most biopsies of a lichenoid keratosis result in complete resolution of the lesion. Even if the entire lesion was not removed with the biopsy specimen, no treatment is necessary….

Syringocystadenoma papilliferum has almost identical central characteristics. Compared with the hidradenoma papilliferum, it has a more dense plasma cell infiltrate and has an attachment to the overlying epidermis, which usually…
Histology: A lone cystic space is seen within the dermis. The cyst is well circumscribed, and the lining of the cyst contains two layers of cells. The cells are cuboidal…
