EOSINOPHILIC PUSTULAR FOLLICULITIS

Abstract

ABSTRACT Pustulosis pulmaris et plantaris‐like lesions occurring often concurrently were studied clinically and histologically with the following results. The incidence of P.P.‐like lesions occurring concurrently with eosinophilic pustular folliculitis is high. It increases and decreases almost in parallel with cutaneous lesions in other regions. It can be differentiated clinically from pustulosis pulmaris et plantaris. Cutaneous lesions are often seen on the elbow and knee in P.P. while it is often found in the face and back in eosinophilic pustular folliculitis. Unlike P.P. and eczema, they have a histology specific to this disease. They have a similarity to histology of the hair‐root sheath. On the basis of the findings above, we think P.P. ‐like lesions are partial symptoms of this disease. Since the palm and sole have no hair follicles, we think it is better to call this disease Eosinophilic pustular dermatosis.
