Summary Background : Although subclinical enthesopathy is a well‐established diagnostic criterion for psoriatic arthritis (PsA), it is frequently overlooked, as many patients are asymptomatic. The possibility of finding a clinical clue predicting enthesopathy would help clinicians establish an early diagnosis of PsA. Material and methods : A prospective single‐center study of a total of 90 patients with psoriasis was conducted to assess the presence of entheseal abnormalities as detected by ultrasound, and to determine any correlation with nail involvement. Results : Entheseal abnormalities were found in 23 patients (25.5 %), 19 (82.6 %) of whom showed nail involvement, whereas four (17.4 %) individuals did not. Enthesopathy was present in 31.1 % (19/61) of patients with onychopathy compared to 13.8 % (4/29) of those without nail involvement (p = 0.07). There was a significant correlation between target NAPSI score and evidence of enthesopathy. In addition, the number of nails affected also showed a significant correlation with the presence of enthesopathy (p = 0.035). Conclusions : Clinical evidence of onychopathy may be the clue to an early diagnosis of enthesopathy in psoriasis patients.
