Idiopathic Palmoplantar Hidradenitis

Abstract

Idiopathic plantar hidradenitis (IPH) is a recently described condition primarily affecting healthy children who develop tender lesions localized to the plantar or lateral aspects of the feet with histologic findings similar to those seen in neutrophilic eccrine hidradenitis (NEH), although with certain notable exceptions including the absence of syringosquamous metaplasia and the presence, in most cases, of neutrophilic abscesses adjacent to eccrine coils. Since its original description, three additional patients have been reported, one with palmoplantar lesions, extending the disease's clinical spectrum to include palmar as well as plantar surfaces. We report on a healthy 8-year-old girl with tender, erythematous nodules on palms and soles and review the literature on this subject.

Generalized idiopathic neutrophilic eccrine hidradenitis in a 7-month-old child

“…In IPH the presence of neutrophilic abscesses adjacent to eccrine coils is more frequent. 4 In our case, the histopathology was similar to that of IPH, except for the involvement of both the ductal and secretory components.…”

Idiopathic palmoplantar eccrine hidradenitis in children

“…Several additional cases (most of them in children) have since been reported under the same name [2,4,7,9].…”

“…Within the last decade, 47 cases of painful erythematous plantar nodules have been reported [1±11], 41 of them in healthy children [1,2,4,6,9,10]. Diagnoses vary because of diverse histological ®ndings.…”

Hot tub folliculitis or hot hand–foot syndrome caused by Pseudomonas aeruginosa

“…[8][9][10][11][12] Idiopathic palmoplantar hidradenitis is characterized by selflimited, tender, erythematous plaques and nodules on the palms or soles of young children, 10,11 with typical neutrophilic infiltrates of the eccrine sweat glands on histopathology. 13 In contrast to ''pseudomonas hot hand or foot syndrome,'' all cases of idiopathic plamoplantar hidradenitis have been sporadic. Searches for infectious organisms have yielded negative results.…”
