ABSTRACT

BACKGROUND

Constriction bands around the digits are termed as ainhum; those which mimic ainhum are termed as pseudoainhum. Ainhum and pseudoainhum can cause autoamputation of the digits. Ainhum which is of idiopathic origin is common in Negros, but rare in rest of the world. Many hypotheses were promulgated for the aetiology of pseudoainhum; however, it has been associated with hereditary palmoplantar keratodermas, systemic sclerosis, leprosy, psoriasis, vascular anomalies etc. We report a case of pseudoainhum associated with pityriasis rubra pilaris (PRP), which has not been reported in the literature so far.
