[Reticulohistiocytoma. Treatment with pulsed-dye laser].
Reticulohistiocytoma is a rare non-Langerhans-cell histiocytosis. On exposed skin areas it is a cosmetic problem and can cause mechanical irritation due to its prominent nature. We successfully treated a histologically confirmed reticulohistiocytoma on the back of a 60 year old woman with a pulsed dye-laser (wavelength 585 nm, pulse 0.45 msec). The lesion regressed significantly after the first treatment (spot size: 7 mm, fluence 7.8 J/cm(2)). After another laser treatment, the lesion completely disappeared. At 28 month follow-up, no recurrence was seen. Permanent side effects were not observed. In our case report the use of the pumped pulsed dye-laser has proven to be an elegant and low risk treatment option for reticulohistiocytoma. The mechanism of action remains unknown.
