Synonym(s)
Basal cell carcinoma pigmented; Pigmented basal cell carcinoma
DefinitionThis section has been translated automatically.
Basal cell carcinoma, mainly of the nodular type, with brown-black pigmented areas due to high melanin content
Clinical featuresThis section has been translated automatically.
Irregularly coloured, sharply defined papules or nodules with brown and/or blue-black parts (depending on the localisation of the pigment accumulations) and typically shiny (atrophic) surface. Incident light microscopy reveals marginal atypical "tumor vessels", which have a high diagnostic value.

HistologyThis section has been translated automatically.
Basal cell carcinoma with numerous pigment-loaded melanocytes located between the tumor cells (immunohistologically detectable) and melanophages in the surrounding tumor stroma. Apart from that, pigmented BCC is not based on any histological features.
Differential diagnosisThis section has been translated automatically.
TherapyThis section has been translated automatically.
Corresponding to the basal cell carcinoma. The special feature of the surgical procedure is the good lateral differentiation possibility. Thus a narrow excision margin of 0.1-0.2 cm is acceptable.
