Talus tuberculosis is a rare disease, even in an endemic tuberculosis area. In reviews of the worldwide literature, only 18 cases of talus tuberculosis have been reported. Recently, we experienced a case of a 70-year-old polycythemia vera patient with right metatarsopharyngeal joint pain for 2 months duration who was diagnosed with talus tuberculosis with prostate involvement. Tuberculosis should be considered as one of the causes of monoarticulitis, especially in countries, where the disease is endemic. Additionally, we highly recommend taking a biopsy of the site of suspected infection because an early diagnosis is the key to successful treatment.
