Freeman and & Laymon (1941) provide a detailed classic description of the disease:<ref name="freeman" /> BXO is usually distinguished by a ring of hardened tissue with a whitish color at the tip of the [[foreskin]]. The hardening of the tissue prevents [[retraction of the foreskin]].<ref name="shankar" /> Immunophenotyping may be useful in differential diagnosis.<ref>Hinchliffe SA, Ciftci AO, Khine MM, ''et al.''

If the biopsy rules out BXO as a cause of non-retractile foreskin, then conservative treatment is most likely possible. If, on the other hand, a biopsy confirms the presence of BXO, the choice of treatment modality is more difficult.
