    Description / Table of Contents: Zusammenfassung Maligne Melanome der Haut sind prognostisch unterschiedlich zu beurteilende, histogenetisch und diagnostisch heterogene bösartige Tumoren, die ihren Ausgang von pigmentbildenden Zellen nehmen. Deshalb richtet sich auch das therapeutische Vorgehen nach einer sorgfältig differenzierenden Diagnostik. (1) Klinische Stadien: I = Primärtumor (PT);II = PT mit regionalem Lymphknotenbefall; III = Fernmetastasen. (2) Klinische und histologische Abtrennung von Lentigo-maligna-Melanom (LM), superfiziell spreitendem Melanom (SSM) und primär knotigem Melanom (NM). (3) Histologische Angabe der Invasionstiefe: Intraepidermal, oberhalb der Basalmembran (Niveau I); Durchbruch der Basalmembran ins Str. papillare (Niveau II); Str. papillare bis zur Grenzzone zum Str. reticulare (Niveau III); gesamtes Str. reticulare (Niveau IV); Subkutis (Niveau V). Therapeutisches Vorgehen: Bei diagnostischen Zweifeln Excisionsbiopsie in Vollnarkose mit einem Sicherheitsabstand von 2 cm, Schnellschnittdiagnose. Ansonsten Entfernung des Tumors mit einem 5 cm-Sicherheitsabstand, gemessen von der Tumorperipherie und tiefenwärts bis zur Muskelfascie, anschließend sofortige Deckung mit einem Transplantat von kontralateralen Körperpartien. Im Gesicht, an Händen und Füßen modifiziertes Vorgehen. Bei klinischem Stadium III zusätzlich Immunochemotherapie mit DTIC und BCG, bei rein cutanen Metastasen auch alleinige äußerliche Immunotherapie mit DNCB oder BCG.
    Notes: Summary Malignant cutaneous melanomas are prognostically variable, histogenetically and diagnostically heterogeneous malignant tumors that stem from pigment-producing cells. Therefore, the therapeutic approach depends on exact differentiation at diagnosis, as to (1) clinical stages: I = primary lesion; II = metastases limited to the regional lymph nodes; III = distant metastases, (2) clinical and histological characteristics, which are different for lentigo malignant melanoma (LM), superficial spreading melanoma (SSM), and primary nodular melanoma (NM), (3) histologic depth of tumor-cell invasion: intradermal with intact basement membrane (level I); through basement membrane down to the papillary dermis (level II); papillary dermis down to the reticular dermis (level III); throughout the reticular dermis (level IV); subcutaneous fat (level V). Therapeutic measures: if the diagnosis is doubtful excision biopsy should be performed under a general anesthetic with a margin of 2 cm (1 cm on the face), and immediate diagnosis should be made from frozen sections. Otherwise all tumor material should be removed down to the fascia, with a margin of 5 cm, and this should be followed immediately by plastic surgery to cover the defect with material from contralateral areas. In clinical stage III, immunochemotherapy with DTIC and BCG is indicated, or if only cutaneous metastases are present, external immunotherapy with DNCB or BCG.
