Hyperkeratotic and verrucous features of mycosis fungoides.

A patient had unusual verrucous and hyperkeratotic plaques and tumors confined to the right leg for 24 years. The histopathologic examination was diagnostic of the infiltrative or plaque stage of mycosis fungoides. The patient was treated with a megavoltage radiation technique that was specially adapted to ensure a homogeneous dose distribution to all the lesions. This treatment may be applicable in other deeply infiltrative cutaneous lesions.
