Lichen sclerosus et atrophicus: atypical case simulating lichen planus

Area of Science:

• Dermatology
• Inflammatory Dermatoses

Background:

• Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory skin condition.
• It typically presents with characteristic skin changes on genital and perineal areas.
• LSA commonly affects prepubertal and postmenopausal women.

Observation:

• An unusual case of isolated extragenital LSA was observed.
• The condition was restricted solely to the wrists.
• The presentation mimicked lichen planus.

Findings:

• This case demonstrates a rare presentation of LSA.
• Extragenital LSA without genital involvement is uncommon.
• Wrist LSA can mimic other dermatological conditions like lichen planus.

Implications:

• Highlights the importance of considering LSA in extragenital skin lesions.
• Broadens the differential diagnosis for wrist dermatoses.
• Suggests further investigation into varied LSA presentations is warranted.
