Acta Derm Venereol 96 © 2016 The Authors. doi: 10.2340/00015555-2396 Journal Compilation © 2016 Acta Dermato-Venereologica. ISSN 0001-5555 A 33-year-old man with a medical history of tenosynovitis of the third finger of his left hand, which had been treated successfully with a local infiltration of glucocorticoids approximately one year previously, was admitted for evaluation of a cutaneous nodule on the same hand. The nodule first appeared 2 months prior to presentation; it had developed rapidly after the patient had injured his palm while travelling through Morocco and cleaned the wound in a river. Physical examination revealed a well-defined, reddish, painful nodule, 2×2 cm, on the palm of his left hand (Fig. 1). No other cutaneous lesions, regional lymphadenopathies or accompanying systemic symptoms were observed.
