“Deck chair sign” presenting in type 1 lepra reaction

摘要

Deck chair sign (DCS) was first described in papuloerythroderma of Ofuji as the characteristic pattern of sparing of the skin folds which resembles the narrow strips of a deck chair. The sparing of skin folds includes areas such as the inguinal, axillary, sub-mammary, and flexural regions. Although first described in papuloerythroderma of Ofuji, it is also seen in other inflammatory dermatoses. We report a case of borderline leprosy in type 1 reaction who presented with the DCS involving the abdominal folds which to the best of our knowledge is the first of its kind.
