The incidence of tuberculosis in the Netherlands has dropped dramatically over the past 50 years. With declining experience of tuberculosis, misdiagnosis can easily happen. Laryngeal tuberculosis often presents as a tumorous mass that may initially be mistaken for cancer. As laryngeal tuberculosis is usually highly infectious, this poses a risk to the patient as well as his/her contacts including healthcare providers. We describe three patients with (suspected) laryngeal tuberculosis and discuss potential pitfalls. Pivotal for a correct diagnosis are thorough history-taking, physical examination and relatively simple radiological and laboratory tests. Risk groups have been identified for tuberculosis and this can provide a clue. Differentiation between tuberculosis and cancer can be difficult, and the two diseases may concur. Even in low-incidence settings for tuberculosis, knowledge of the disease remains necessary as it is curable and further spread can be prevented with simple measures.
