Summary
Acral lentiginous melanoma (ALM) is an uncommon melanoma type among Caucasions. ALM bears an unfavorable prognosis because of late presentation or common misdiagnosis. Amelanotic variants, albeit rare, may pose an additional clinical challenge and may further delay the diagnosis and treatment. Thus, the threshold for biopsying even marginally suspicious lesions should be low. We present two cases of Caucasian patients with amelanotic subungual ALM, stage 2a and 2c respectively, successfully treated with a functional amputation.
Zusammenfassung
Das akolentiginöse Melanom (ALM) ist unter Kaukasiern eher selten. ALM ist mit einer ungünstigen Prognose verknüpft infolge verzögerter Diagnose und von Fehldiagnosen. Seine amelanotische Variante ist selten, führt jedoch häufiger zu weiterer diagnostischer Verzögerung. Deshalb sollten verdächtige Läsionen frühzeitig bioptiert werden. Wir stellen 2 Patienten mit amelanotischem ALM, Stadium 2a und 2c, vor, die mittels funktioneller Amputation erfolgreich behandelt wurden.
