Liesegang rings in an apocrine hidrocystoma: a case report and review of literature.
Liesegang rings represent an in vivo chemical precipitation phenomenon representing a potential diagnostic pitfall for misdiagnosis as parasitic infections. These acellular patterns of lamellar concretions are rare in human tissue. The authors report a case of Liesegang rings observed within an intradermal apocrine hidrocystoma and review the literature for reports of these structures, with particular emphasis on mucocutaneous lesions.
