Zusammenfassung:Pachydermoperiostosis is a rare genetic disorder characterized by skin thickening, digital clubbing and periostitis. The pathogenesis is incompletely understood and there are no proven treatments for its manifestations. Although arthritis has been reported in 20-40% cases, most are non-inflammatory in nature and usually treated symptomatically with steroids or NSAIDs. We report two cases of pachydermoperiostosis with inflammatory variant of arthritis and raised inflammatory markers who were treated with tapering dose of prednisolone for 6 weeks and maintained on long-term low dose methotrexate like rheumatoid arthritis and followed for 2 years. In both cases, methotrexate was well tolerated and helped in maintaining symptomatic improvement and slowed the disease progression with significant steroid and NSAID sparing effect. We concluded that there exists an inflammatory subtype of disease where methotrexate can be beneficial.
