Abstract

The aim of this study was to ascertain which histological types of melanoma can clinically and morphologically appear
as polypoid melanomas. In 645 cases of primary cutaneous melanoma we have analyzed criteria for diagnosis of
polypoid cutaneous melanoma and afterwards we have analyzed growth phase in each polypoid melanoma, histological
type of atypical melanocytes, the number of epidermal ridges which are occupied by atypical melanocytes, and distribution
according to age, sex and location, as well as the disease free survival. According to the criteria for polypoid melanomas
we have found 147 (22.8%) polypoid cutaneous melanomas. Analyzing the growth phases, histological types of atypical
melanocytes and the number of affected epidermal ridges in the group of polypoid melanomas we have ascertained 2
(1.4%) ALMs, 4 (2.8%) LMMs, 42 (28.6%) SSMs and 99 (67.2%) NMs. Our conclusion is that polypoid cutaneous melanomas
are morphological forms of various histological melanoma types (ALM, LMM, SSM and NM) and they can all display
polypoid morphological form. Polypoid cutaneous melanomas are most often of nodular histological type.
