Removal of the deep fascia is recommended in therapy for dermatofibrosarcoma protuberans, but its necessity in the context of micrographic surgery is unclear. A retrospective clinicopathological analysis of 48 patients with dermatofibrosarcoma protuberans treated by micrographic surgery was performed, to determine in which tumours fascia preservation was feasible and safe. Histologically, 93% of tumours on the trunk and extremities and 14% of tumours in the head and neck region were fully located above the fascia. Localization on the head and neck was the only significant risk factor for tumour extension beyond the subcutis (p

Electrical impedance spectroscopy is a non-invasive technique that can help clinicians in diagnosing malignant skin tumours. Depending on the cellular irregularity of the lesion, electrical impedance spectroscopy can reveal changes in the structure and form of the cells, using a harmless electrical current applied to the skin. A score between 0 and 10 is generated by the electrical impedance spectrometer, where 0 is considered benign and 10 is malignant. This prospective study was conducted in 101 patients with a total of 200 skin lesions; 62 benign and 138 malignant. There was a significant difference between the electrical impedance of malignant and benign lesions (p
