Abstract: Photoonycholysis may be seen as a part of Segal's triad, photosensitivity followed by discoloration of the nails and onycholysis. But the latter may also appear, independently, in the absence of photosensitive reaction elsewhere.Photoonycholysis may result from drug intake, porphyria cutanea tarda, erythropoietic porphyria, erythropoietic protoporphyria, variegate porphyria and pseudoporphyria. Rarely, spontaneous photoonycholysis may be observed.Four distinct subtypes have been recorded without relationship between the responsible drugs and the different clinical varieties of photoonycholysis. Primary photohemorrhage can occur; it can also be associated with polydactylous photoonycholysis type III.The inability to reproduce photoonycholysis experimentally should be emphasized.
