Abstract
Cutaneous lesions of two cases of lichen planus and three cases of lichenoid drug eruption were studied by electron microscopy with special reference to the so-called colloid bodies. The results are summarized as follows. Colloid bodies are seen separately or in groups in the lower epidermis, dermo-epidermal junction and upper dermis. They are composed of irregulaly in the waven fibrils, 75-85 Å in diameter. Some mitochondria and melanosomes are seen with in the bodies. Infrequently covered with the plasma membrane which has some tonofilament-desmosome complexes in contact with the fibrils.
