ABSTRACT
Indeterminate cell histiocytosis is a rare disorder involving altered homing mechanisms of the cutaneous histiocytic/dendritic system. It has been described predominantly in adults, with less than a dozen cases in children. A 13-year-old adolescent girl presented with a 4-year history of asymptomatic erythematous nodules and plaques, measuring from 1 to 5 cm in diameter, that were located mainly on the trunk and proximal portions of her limbs. A skin biopsy showed dermal diffuse infiltration of histiocytic cells. Most of the histiocytic cells were strongly positive for S100 protein. No Birbeck granules were found. Treatment with topical steroid was ineffective. After 6 months of pure coal tar and 5% 5-fluorouracil cream, an almost total clearing of lesions was observed. An accurate diagnosis of this condition is mandatory in order to avoid unnecessary treatments. Conservative management is also discussed.
