An Unusual Manifestation of ORF

The pseudotumoral presentation of Orf is very rare with few cases reported in the literature. It is usually characterized by a single papule which rapidly evolves taking up a nodular appearance. The diagnosis is usually established clinically based on patient history and the characteristics of the nodule. However pseudotumoral forms of this disease requires a skin biopsy in order to eliminate the main its differential diagnoses which are the squamous cell carcinoma and achromic melanoma. Orf is known to generally evolve favorably with a spontaneous regression of lesions. We report the clinical and dermatoscopic aspects of an interesting case involving a giant skin tumor.
