Abstract

Background/Objectives: Basal cell nevus syndrome (BCNS) is an autosomal dominant skin cancer predisposition syndrome associated with abnormal mineral metabolism, a risk factor for urinary stone disease (USD). However, no research investigating the association between BCNS and USD or other manifestations of abnormal mineral metabolism has been conducted. The objective of this study is to investigate the association between BCNS and conditions associated with disordered mineral metabolism including USD, hypothyroidism, and osteoporosis and compare them to prevalence in the general population to elucidate potential unknown manifestations of the condition. Methods: This retrospective study examined medical records of adult and pediatric patients with confirmed BCNS from the Mayo Clinic database from 1 January 1995 to 12 January 2020. Records were surveyed for evidence of USD and other comorbidities potentially related to BCNS. The studied cohort included 100 adult patients and 5 pediatric patients. Results: A total of 105 patients were included in this analysis, 10 of whom experienced confirmed USD, representing a prevalence of 10%. Six adult patients were identified with a diagnosis of osteoporosis, representing a prevalence of 6%. Thirteen adult patients were identified with a diagnosis of hypothyroidism, representing a prevalence of 13%. Conclusions: This study identified a prevalence of USD in BCNS patients comparable to estimates of national prevalence, indicating that known abnormalities in mineral metabolism likely do not increase the incidence of USD in BCNS patients. Additional findings included increased prevalence of hypothyroidism and decreased prevalence of osteoporosis in the BCNS cohort compared to national averages.
