Recurrent adult idiopathic neutrophilic eccrine hidradenitis treated with colchicine: A case report

Idiopathic neutrophilic eccrine Hidradenitis is usually observed in healthy children with tender erythematous nodules on the soles or palms. We report a case of a 26-year-old man with a painful erythematous swollen patch on both hands and feet. His symptom recurred once monthly over 2 years; thus, he visited Orthopedics. However, no bony abnormality was identified. We performed a skin biopsy on an erythematous indurated patch on his right sole. Histopathological findings indicated neutrophilic eccrine hidradenitis. After 2 weeks of treatment with oral colchicine, his symptom resolved, and no relapses were observed during follow-up. Only a few case reports describe idiopathic neutrophilic eccrine hidradenitis in adults, which is not associated with malignant hematological disease, solid cancer, and chemotherapy. Conventional treatment comprises bed-rest and the administration of topical steroids. Colchicine can be a good treatment option for adults with severe or recurrent idiopathic neutrophilic eccrine hidradenitis.
