Question
All are true about malignant melanoma EXCEPT
Answer
Correct answer: d) Peripheral palisading of tumour cell Nests are seen in microscopic sections Question numbers (vi)-(x) are multiple response type questions. Read the statements & mark the answers appropriately.
This is the exception (FALSE statement). Peripheral palisading of nuclei at the edge of tumour nests is a characteristic feature of basal cell carcinoma, not melanoma. Malignant melanoma genuinely does show a radial (horizontal, intraepidermal) growth phase followed by a vertical (dermal-invasive) growth phase (option a, true), can undergo spontaneous regression of the primary tumour (sometimes leaving only metastases with an unknown primary, option b, true), and metastatic deposits are often black/pigmented due to melanin production by tumour cells (option c, true).
