Benign dermal iridophore aggregates in a crested gecko (Correlophus ciliatus)

摘要

A 1-year-old, female intact crested gecko was evaluated because of skin discoloration on her ventrum. Full-thickness biopsies were taken and evaluated histologically. Multifocally and regularly, there were collections of birefringent, granular material, localized primarily to the most superficial dermis subjacent to the overlying epithelium, throughout the length of examined sections. Polarized illumination revealed birefringent iridophores. This case either represents a benign aggregation of iridophores or simply regions of variable depigmentation, which may be considered as differential diagnoses when geckos are presented with similar clinical signs.
