| Popis: | Over the years, keratoacanthomas have been described as some of the most common skin lesions with the potential for malignant transformation, thus constituting an important risk factor for the development of squamous cell carcinoma. The quantification of the risk of malignant transformation is conditioned by the clinical–morphological and etiopathogenic variability of these lesions, with a negative impact on diagnostic and therapeutic management. In this sense, the main objective of this research is to characterize from an ultrastructural perspective the specific tumour microenvironment, by using a technique with a higher resolution power than photon microscopy. Keratoacanthoma lesions from 25 patients were excised from healthy tissue and then processed by classical electron microscopy and examined with the Philips CM100 microscope. The electron microscopic study revealed structural details suggestive of malignant transformation, capturing changes at both cytoplasmic and membranous levels. The identification and description of the ultrastructural morphological substrate favouring the evolution and progression of the studied lesions correlates directly with the improvement of the prognosis and quality of life of these patients. |
