RESUMEN
Chronic ulceration can be complicated by development of a malignancy. The most frequent associated malignances are squamous cell carcinoma and basal cell carcinoma, although melanoma, leiomyosarcoma and adenocarcinoma are less commonly seen. Chronic lymphoedema may also predispose to development of some malignancies, including lymphangiosarcoma, squamous cell carcinoma and Kaposi's sarcoma. Here, we report the case of a 77-year-old man with primary lymphoedema, who developed melanoma in a chronic foot ulcer of 60 years' duration. The patient underwent wide excision for the melanoma, and remains free from metastases at 1-year follow up.

Eruptive disseminated Spitz naevi is a rarely reported condition. Although the dermatoscopic features of nondisseminated, solitary forms of Spitz naevi are well known, there are no reports describing the dermatoscopic features of eruptive disseminated variant. We report an additional case and describe the dermatoscopic features. Two patterns were observed. In all pink lesions, the vascular pattern was seen, composed of dotted, linear or comma-like vessels located at the centre of the meshes of the reticular depigmentation. In all brown lesions, we observed only the reticular pattern, which is quite interesting as the reticular pattern is a rare feature of Spitz naevi. This observation may be a special feature particularly seen in the eruptive disseminated variant. A superficial black network also accompanied reticular pattern in some lesions. In dichromatic lesions, both patterns were observed in different areas of the body.
