Immunocompromised areas of the skin, caused by chronic lymphoedema, paraplegia, infections or traumas, represent a site of regional neuroimmunocutaneous destabilization, termed the immunocompromised cutaneous district (ICD), in which malignancies and other opportunistic disorders are more likely to occur. We report the case of a metastatic porocarcinoma (PC) occurring on a lymphoedematous limb in a 72-year-old man. We reviewed the literature to better understand the potential pathogenetic mechanisms behind this condition. It has been reported that removal of the leg vein destroys the medial group of the superficial lymphatic vessels and alters the normal lymph drainage of the leg, predisposing to recurrent cellulitis. Our observations suggest that saphenous venectomy can induce development of an ICD. We suggest that PC, a rare cutaneous tumour, should be included in the growing list of tumours arising in the ICD.
