Melanoma is a tumor that develops as a result of the malignant transformation of the melanocytes. There is a worldwide estimate of 132,000 new cases per year. This case study presents a 70-year-old male person with history of Diabetes Mellitus type 2 for 10 years and extensive psoriasis vulgaris for 6 years. The patient developed an ulcerated lesion in the plantar region of the right foot in one-year time period. The histological examination revealed an ulcerated malignant melanoma, Clark level V, 5.6 mm thick (Breslow). The lesion was surgically removed and the sentinel lymph node biopsy was negative. Initial conclusions revealed an advanced state of evolution of the primary tumor (TNM IIC). CAT scan detected gastric metastasis, reclassifying the illness as a TNM IV stage. Malignant melanoma may be difficult to diagnose, as it was possible to observe in this case study, where a foot ulcer was late diagnosed, delaying the diagnosis of a severe neoplasia with high mortality rate.
