Conventional teaching holds that UV-B radiation from sunlight or tanning beds cannot induce vitamin D toxicity (1).Objective: To support recent information that contradicts this conventional teaching (2).Case Report: A 48-year-old postmenopausal woman developed a spontaneous pubic and bilateral sacrum fracture in December 2012.
