ESTRADA, Bruna Duque; AZEVEDO, Patrícia Mesquita Couto de; TAMLER, Carla and AVELEIRA, João Carlos Regazzi. Comparative dermatology: hyperkeratotic psoriasis. An. Bras. Dermatol. [online]. 2007, vol.82, n.4, pp.369-371. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962007000400013.
Psoriasis is a skin disorder with several clinical expressions. Hyperkeratotic lesions may be observed, and have been named rupioid, elephantine, ostraceous and pseudohorny in the literature. It is worth noting that two of such denominations refer to the similarity they bear with shells found by the study of conchology, namely rupioid and ostraceous. The authors compare the morphological aspects of hyperkeratotic psoriasis variants with the shells of different mollusk species.
