LATE METASTASES OF CUTANEOUS MELANOMA - CASE-REPORT AND LITERATURE-REVIEW

The development of delayed metastases, although rare, is well documented in patients with invasive cutaneous melanoma. Only 24 cases, including ours, are clearly documented in the literature. We describe a 56-year-old woman who had an acral lentiginous melanoma of the right hand (thickness 1.2 mm). Thirteen years after excision and postoperative irradiation, a subcutaneous metastasis developed in the right arm. One year later the patient died with disseminated bone metastases. This case, as with most of those with delayed metastases, has typical features: female sex; location at a site other than the back, arm, neck, or scalp; and primary tumor thickness between 1.2 and 2.5 mm.
