title: Perianal pseudoverrucous papules and nodules.
abstract: Perianal pseudoverrucous papules and nodules (PPPN) is a rare entity attributed to chronic irritation. We came across this entity in a case of spina bifida. A 14 year old girl having spina bifida at L3 presented with complaints of multiple asymptomatic whitish lesions on the inner aspect of thighs and labia majora since early childhood. She had incontinence of stool and urine since birth. Cutaneous examination revealed multiple 3-12 mm flat topped moist papules, few verrucous nodules, some of these lesions coalesced to form plaques at the perianal area extending upto the labia majora. On histology marked epidermal hyperplasia and pale keratinocytes in the epidermis was seen. This confirmed the diagnosis of PPPN. This rare condition can be mistaken with sexually transmitted diseases leading to unnecessary investigations and treatment.
