Carcinoma cuniculatum was first described by Aird . This tumor is a rare, lowgrade variant of squamous cell carcinoma characterized by a local aggressive clinical behavior but a low potential for metastasis. In a sufficiently deep specimen, deeply penetrating epithelial strands composed of a atypical keratinocytes are seen. These strands intertwine, often forming crypts containing keratinous debris, giving the overall appearance of a rabbit warren, hence the name cuniculatum was made. We describe here 2 patients with carcinoma cuniculatum involving the foot and the hand.
