A Rare Case of Lichen Planus-Like Atopic Dermatitis Involving the Hands

Area of Science:

• Dermatology
• Pathology

Background:

• Lichen planus-like atopic dermatitis (LPLAD) clinically resembles lichen planus, creating diagnostic difficulties.
• LPLAD can present as intensely pruritic papules and plaques, particularly on the hands.

Observation:

• A 55-year-old African American woman presented with intensely itchy papules and plaques on both hands.
• The clinical presentation mimicked lichen planus.

Findings:

• Histopathological examination revealed acute spongiotic dermatitis.
• Significant lymphocyte exocytosis into the epidermis was observed.

Implications:

• This case demonstrates that LPLAD can manifest on the hands.
• Accurate diagnosis requires correlating clinical presentation with histopathological findings.
• This correlation is crucial for effective patient management.
