Clinical data 31 patients in this group, 26 males and 5 females. The age of onset was 25 to 83 years old, with an average age of 55 years. Among them, 7 cases of definite predisposing factors resulted in the formation of unstable scars after burns, and ulcerations due to scratching and lying in the joints, etc., caused ulceration and ulceration, and eventually resolved to canceration. There were no obvious incentives in 24 patients. None of the 31 patients had family history. The disease duration ranged from 10 months to 7 years. Most of the elderly patients were treated by local hospitals for recurrence. Those with short duration were soon to be diagnosed in our hospital. Lesions: 7 limbs, 7 trunks, 17 head and face. The lesions ranged from 1.5 cm×1.5 cm to 10 cm×9 cm. Three patients had regional lymphadenopathy. Two patients underwent lymphadenectomy. The pathological diagnosis was chronic inflammation. No distant organ metastasis was found in 31 cases, including 24 cases of squamous cell carcinoma, 5 cases of basal cell carcinoma, 1 case of verrucous carcinoma, and 1 case of malignant fibrous histiocytic carcinoma.
