Abstract

The objective of this study is to describe a clinical case of melanoacanthoma, as a rare variant of seborrheic keratosis, which hides the ability to mimic melanoma and determine the diagnostic algorithm for patient management, further doctor’s tactics, based on clinical-dermatoscopy-pathomorphological features. Materials and methods. Visual assessment of the neoplasm using the ABCDE algorithm, dermatoscopic examination to determine characteristic patterns and the use of a scale of 11 criteria according to S. Menzies, pathomorphological and immunohistochemical studies. Results. A 32-year-old woman has a neoplasia suspicious for melanoma on the basis of a comprehensive visual and dermatoscopy examination. As a result of excisional removal and pathomorphological conclusion, it is legitimate to formulate the final diagnosis in the context of variation of seborrheic keratosis. Conclusions. Melanoacanthoma is a rare variant of seborrheic keratosis that clinically resembles melanoma and requires an individualized diagnostic algorithm.
