The pathological examination revealed minimal diathermia artifacts of less than 1-mm on the margins of sample cross-sections, but these caused no problem in histology.
There are three thermotherapeutic approaches: diathermia (temperature increase of tissue by 1-3[degrees] C, particularly used in physiotherapy), hyperthermia (temperature increase by 4-8[degrees]C in treated tissue, mostly used in oncology) and ablation (temperature increase by 20-30[degrees]C, used in oncology, urology, cardiology etc.).
Cryotherapy, curettage and electrodessication, radiotherapy, topical application of 5-fluorouracil or imiquimod, electrodessication with curettage, and diathermia are the appropriate treatment options for superficial BCC and Bowen's disease of the thorax and limbs.
