Une cause inhabituelle de retard d’acquisition de la marche : l’hidradénite palmo-plantaire idiopathique

Idiopathic palmoplantar hidradenitis is an uncommon neutrophilic dermatosis, occurring in children and young adults. Its pathogenesis is incompletely understood. It is characterized by spontaneous resolution, but it can relapse in 50% of cases. We describe a case of a child with atypical idiopathic hidradenitis remarkable for its impact on his motor development. A 3-year-old boy was admitted to the pediatric unit for etiological assessment of delayed walking. Medullary MRI and TSH were normal. He was referred to a dermatologic consultation for recurrent and painful palmoplantar lesions, giving an equinus antalgic posture. Examination found erythematous tender plantar nodules. The palms were not affected. The exam was otherwise normal. Diagnosis of idiopathic plantar hidradenitis, pressure urticaria, and plantar erythema nodosum were discussed, leading to a skin biopsy. The histopathologic findings of nodular, neutrophilic infiltrates around the eccrine glands confirmed the diagnosis of idiopathic plantar hidradenitis. Anti-inflammatory treatment was given, followed by complete resolution of the lesions, but persistent equinus posture. Idiopathic palmoplantar hidradenitis is an uncommon neutrophilic dermatosis, distinct from neutrophilic eccrine hidradenitis. It corresponds to neutrophilic infiltrates of the eccrine sweat glands. It is more frequently reported in children and young adults with no medical history. Its pathogenesis is not completely explained. The lesions are usually painful, hindering walking for a few days or even delaying it, as for our patient. These lesions typically involute, but they may recur in more than half of the cases. Through this observation, we highlight the atypical impact of idiopathic hidradenitis and the value of a dermatological examination in case of delayed walking.

Hot-Foot-Syndrom oder palmoplantare Hidradenitis?

Some y ears ago, Canadian authors described the so-called hot foot syndrome, obviously a palmoplantar hidradenitis due to Pseudomonas aeruginosa. There are distinct similarities between this syndrome and the whirlpool dermatitis (a folliculitis due to Pseudomonas aeruginosa). The clinical manifestation of the hot foot syndrome is on the whole the same as that of the idiopathic recurrent palmoplantar hidradenitis, whose pathogenesis is unknown. The authors suggest that at least some of the patients with idiopathic recurrent palmoplantar hidradenitis are indeed cases of hot foot syndrome. Originalarbeit

Pustular idiopathic recurrent palmoplantar hidradenitis: An unusual clinical feature

A 12-year-old boy had painful lesions on both soles. He had had a similar episode several months before that resolved spontaneously. Physical examination showed erythematous, extremely tender nodules on both plantar surfaces and the toes. The second and third left toes had small pustules on top of the nodules. There was no palmar involvement. The clinical features, pathologic findings, and self-limited course suggested recurrent palmoplantar hidradenitis. This distinctive entity of unknown origin appears during childhood and is characterized histologically by a neutrophilic infiltrate affecting the eccrine glands. We report the case of a patient with unusual clinical features. (J Am Acad Dermatol 2002;47:S263-5.)

Recurrent palmoplantar hidradenitis in childhood

We describe five cases of recurrent palmoplantar hidradenitis in children. The pathogenesis of this highly characteristic disease presenting with painful erythematous papules and nodules involving palms of the hands, soles of the feet, or both is not clear at the moment. One possible mechanism is a temporal relationship between exposure to dampness and cold, which also applied in four of these children. The self-limited disease tends to reappear. After thoroughly informing the children and their parents on avoiding provoking factors, all children experienced freedom from the disease during a 12-month follow-up.

Palmoplantar Eccrine Hidradenitis: Three New Cases and Review

Abstract: Palmoplantar eccrine hidradenitis (PEH) is characterized by painful erythematous papules and nodules of abrupt onset on the soles of young individuals. The histologic hallmark is a predominant neutrophilic infiltrate surrounding the eccrine gland apparatus. A total of 28 cases have been published since 1988, with a broad variation in the age of patients, symptomatology, associated diseases, clinical course, and histologic features. These different histologic pictures have resulted in several names for this entity, including idiopathic plantar hidradenitis, neutrophilic eccrine hidradenitis, recurrent palmoplantar hidradenitis in children, and idiopathic palmoplantar hidradenitis. We present three cases of this disorder and review the literature on the varying symptomatology, clinical course, and histology that have led to the myriad of names for this disease.

Idiopathic recurrent palmoplantar hidradenitis in children. Report of 22 cases.

Idiopathic recurrent palmoplantar hidradenitis (IRPH) is characterized by tender erythematous plaques and nodules on the soles and, less often, the palms of young patients. To date, 10 cases of IRPH have been documented in the literature. We describe 22 pediatric patients with characteristic cutaneous and histologic findings of IRPH. Their mean age was 6 years (age range, 1.5-15 years). The onset of the disease clustered in 2 peaks, in autumn and spring. All patients had complete resolution of their lesions within 3 weeks, in 16 cases without any treatment. Ten of the 22 patients experienced more than 1 episode of IRPH. Our study represents the largest number of cases of IRPH collected to date. Based on our data, the clinical picture is so characteristic that a histopathologic examination may not be necessary in every case. We suggest that there is a seasonality in the occurrence of this always benign and limited disease.

Recurrent Palmoplantar Hidradenitis in Children

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. 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. 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.
