Abstract:
The association between penile lichen sclerosus and striking accumulation of elastic fibers in deep dermis has been described in rare reports, mostly in vulvar lesions. We describe one case of severe balanopreputial adhesions related to lichen sclerosus and this form of elastosis, with no concomitant neoplasia. Aggregates of elastic fibers were seen in deep dermis and in blood vessels. The lesion mirrors nevus elasticus and nevus elasticus vascularis - a well described cutaneous lesion with no known association with lichen sclerosus.

Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
