“…Talar callosity, also known as callosity of crossed-legged sitting, is uncommon in occidental countries, but it is frequently seen in Arabic and Asian cultures, in relation to prayer [3][4][5], meditation [11], and other activities that involve crossed-legged sitting [1], such as yoga or even eating in some countries (e.g., India) [2]. Talar callosity has been previously described in children in relation to crossed-legged or kneeling positions on the floor [12]. The callosity can vary in its location, from the anterolateral aspect to the dorsum of the feet, depending on the adopted posture, and the location is usually away from common shoe contacts.…”

Talar callosity is an uncommon condition characterized by asymptomatic hyperkeratotic plaques located on the dorsum of one or both feet. We have detected an increased number of children presenting with this condition after the COVID-19 lockdown. High-frequency ultrasound was performed in all patients who consulted because of talar callosity. All four cases shared similar ultrasound findings: thickening of the epidermis with effacement of the subepidermal low-echogenic band and diffuse thickening of the dermis and subcutaneous cellular tissue, with a diffuse decrease in echogenicity. The bone cortex was respected in all cases. No increase in vascularization was detected. Although it is a benign condition, it is important to recognize talar callosity to exclude worse conditions and to prevent unnecessary biopsies. To our knowledge, we are the first to describe ultrasonographic findings of talar callosity.
