Besnier's prurigo

Prurigo gestationis (also called "Besnier prurigo", "Early-onset prurigo of pregnancy," "Linear IgM dermatosis of pregnancy," "Papular dermatitis of pregnancy," "Prurigo of pregnancy", and "Spangler's papular dermatitis of pregnancy") is an eruption consisting of pruritic, excoriated papules of the proximal limbs and upper trunk, most often occurring between the 20th and 34th week of gestation.

The exact etiology is unknown, but it is considered likely to be a flareup of atopic dermatitis during pregnancy.

It is sometimes considered to be a term encompassing Besnier prurigo and other conditions.

It is sometimes considered a diagnosis of exclusion.
