Background:  There are several reports of tender, erythematous plantar nodules occurring in pediatric patients. Despite similar morphological features, the histologic findings in these lesions have been quite diverse. A new entity called idiopathic plantar hidradenitis (also termed neutrophilic eccrine hidradenitis in children), which is characterized by tender, red nodules on the feet and unique histopathologic features, was recently described.

Observations:  We describe two children with these unusual cutaneous lesions and histopathologic findings and compare them with patients with idiopathic plantar hidradenitis. Our patients, in contrast to those with idiopathic plantar hidradenitis, had involvement of the palms as well as the soles. Both children had self-limited recurrent lesions; in one child, the lesions were associated with low-grade fever. Biopsy specimen findings in both cases demonstrated dense neutrophilic infiltrates localized to the eccrine units.

Conclusions:  Our patients had clinical and histologic findings similar to those recently reported as idiopathic plantar hidradenitis (neutrophilic eccrine hidradenitis in children). Because palms and soles can be affected and the lesions typically recur, we suggest that this condition be referred to as recurrent palmoplantar hidradenitis.(Arch Dermatol. 1995;131:817-820)
