Resumo: To describe the clinical-pathological and treatment data of an 86-years-old, non-smoker, Caucasian female with a solitary, asymptomatic, slowly enlarging, and cylindrical growth on the lower lip with more than 10 years of evolution. She denied sunlight chronic exposure, trauma, spontaneous bleeding, or ulceration. A clinical diagnosis of undetermined nature CH was achieved, and an excisional biopsy was performed. The histopathological examination depicted a hyperkeratotic conical growth. At the base of the lesion, the stratified squamous epithelium exhibited hyperkeratosis, spongiosis, acanthosis and mild‑to‑moderate epithelial dysplasia. The definitive diagnosis was CH associated with actinic keratosis. No clinical relapses were detected after four years. Less than 25 similar cases have been published, demonstrating that CH is a relatively unusual lesion, affecting mostly the sun exposed areas of mid-aged Caucasian without gender predilection. Excision should be the treatment of choice to enable diagnosis of the underlying lesion since most were associated with pre-malignant/malignant diseases.
