Bilateral hand dactylitis: An unusual presentation of the great imitator: Tuberculosis.

The incidence of tuberculosis in developed countries has decreased over the years due to the use of effective tuberculosis drugs and improvements in socio-economic conditions. However, with the ease of global transport and increased travel to countries with high tuberculosis prevalence, the reduction in extrapulmonary tuberculosis cases has been less significant compared with the overall decrease in tuberculosis cases. Extrapulmonary tuberculosis can manifest in a variety of ways. Tuberculous dactylitis, a rare form of tuberculous osteomyelitis, was first described by Rankin in 1886. It mainly affects the short tubular bones in the hands and feet of children and is sometimes called 'spina ventosa'. A 42-year-old male patient initially presented to an external centre reporting swelling and pain in the hand joints of one year's duration. Despite one year of treatment with leflunomide and methylprednisolone (16 mg) and a history of methotrexate use during this period, he experienced no improvement. The patient's condition worsened after the start of sulfasalazine. Dermatological examination was performed due to the presence of haemorrhagic crusted papules and plaques on the ventral surface of both hands. A wound culture was taken, but no bacterial growth was observed. One week after the initial evaluation, the patient complained of persistent foul-smelling nasal discharge, which led to an evaluation by the infectious disease department. At this time, the Quantiferon test was positive. Mycobacterial culture on Days 1 and 3 showed growth of the Mycobacterium tuberculosis complex.
