Description

Total body mapping (TBM) comprises photographic documentation of the entire body surface. Total body photography (TBP) is followed by digital dermatoscopy (DD) of selected melanocytic lesions. A 2-step approach combining both can facilitate the detection of new lesions or early macroscopic changes in existing lesions. We present 50 years old man with pigmented nodular lesion on his left shoulder, which had started bleeding for a short time. No family history of melanoma, sunburns during adulthood. Patient had multiple polymorphic nevi on his body (>1000). Clinical and dermatoscopic examination showed thick melanoma criteria. Excisional biopsy was performed. Morphology - melanoma pT2aN0M0 IB stage, Breslow 2 mm, Clark III. First TBM session was performed on December 2019, the next two with an interval of 3 months. Lesion on back was excised with result melanoma in situ. The next TBM was performed with an interval of 6 months. High magnification DD was performed for a new lesion on his right hip 1.32 mm x1.28 mm with peripheral globules. Another lesion on his left leg with changes was excised with result spitzoid melanoma Breslow - 0.2 mm. Follow up for the nevus on right hip - no more peripheral globules in 3 months. TBM after 3 months - new nevus on patients abdomen with peripheral rim of globules, additional high magnification DD was performed - peripheral globules symmetric and regular. A 2-step approach combining TBP and DD is currently the best for monitoring patients at high risk for melanoma. This combination significantly improves the management of patients, that would be difficult without these technologies. Diagnosis of melanoma in such cases would be possible when the tumor is in an invasive stage. New lesions with signs of growth at 50 years of age do not always mean malignancy.. .. .. .
