Penile Lichen Sclerosus and "Nevus Elasticus"

Area of Science:

• Dermatology
• Pathology

Background:

• Penile lichen sclerosus is a chronic inflammatory skin condition.
• Rare reports link lichen sclerosus to elastic fiber accumulation, primarily in vulvar lesions.
• Elastosis in deep dermis and blood vessels is uncommon in penile lichen sclerosus.

Observation:

• A case of severe balanopreputial adhesions linked to lichen sclerosus was observed.
• The condition presented with striking elastosis in the deep dermis and blood vessels.

Findings:

• The penile lichen sclerosus case demonstrated significant elastic fiber deposition.
• Histological examination revealed aggregates of elastic fibers in the deep dermis and within blood vessels.
• No evidence of concomitant neoplasia was found in the affected tissue.

Implications:

• This case expands the understanding of penile lichen sclerosus manifestations.
• The findings suggest a potential link between lichen sclerosus and specific forms of cutaneous elastosis.
• Further research may clarify the pathogenesis and clinical significance of this association.
