[Granulofilamentous intranuclear bodies detected by ultrastructural studies in lichen planus and psoriasis]

Based on ultrastructural studies and findings reported in the literature occurrence, frequency, morphological and structural pattern of intranuclear inclusions in lichen ruber planus and psoriasis were analyzed and compared with other structures. It was concluded that granulofilamentar bodies in lichen and psoriasis are not specific structures. They develop as an effect of physiologic and pathologic (hyper) activating factors and may be reversible. Granulofilamentar structures seem to represent separate group of intranuclear bodies. To clear up their features further investigations are needed.
