The patient, who had a 20-year remote history of sarcoidosis (treatment naive), developed a clinically symptomatic exacerbation of sarcoidosis one month following initiation of atezolizumab along with increased hilar nodules on imaging, skin nodules, arthritis and uveitis. Biopsy of a lymph node revealed non-necrotising granulomas, and biopsy of the skin showed panniculitis. The patient also developed colitis, speculated to be an immune-related adverse event.
