Associated conditions
Dactylitis can occur in seronegative arthropathies, such as psoriatic arthritis and ankylosing spondylitis, and in sickle-cell disease as result of a vasoocclusive crisis with bone infarcts, and in infectious conditions including tuberculosis, syphilis, and leprosy. In reactive arthritis, sausage fingers occur due to synovitis.Robbins, Stanley Leonard; Kumar, Vinay; Abbas, Abdul K.; Cotran, Ramzi S.; Fausto, Nelson (2010). "Robbins and Cotran pathologic basis of disease". In Vinay Kumar, Abul K. Abbas, Nelson Fausto. Robbins Pathology Series (Elsevier). p. 205. {{ISBN|978-1-4160-3121-5}}. Dactylitis may also be seen with sarcoidosis.
In sickle-cell disease it typically occurs after 6 months of age (as in infants protective fetal hemoglobin, HbF, is replaced with adult hemoglobin and the disease manifests) and is often the first clinical presentation of the disorder.{{cite journal |last1=Buchanan |first1=Ivy |title=DACTYLITIS |journal=Nursing Clinics of North America |date=1 March 1983 |volume=18 |issue=1 |page=141 |doi=10.1016/S0029-6465(22)01712-1 |url=https://www.sciencedirect.com/science/article/pii/S0029646522017121 |issn=0029-6465}}
