Metastatic Melanoma



Metastatic Melanoma


Esther Oliva, MD










Metastatic malignant melanoma has a vague nodular appearance and may show a strikingly black cut surface due to the presence of melanin pigment.






Metastatic melanoma most often grows in sheets, and the cells have abundant eosinophilic cytoplasm, marked nuclear pleomorphism, and mitoses. Notice intracytoplasmic melanin pigment image.
