The nurse suspects that an older adult patient has features of basal cell carcinoma appearing in form of a small dome-shaped lesion with a pearly surface on the face.
What is Basal cell carcinoma?
The most prevalent type of skin cancer that is not melanoma is basal cell carcinoma (BCC).
- It is a tumour that causes localized damage and has a variety of clinical and histological characteristics.
- When viewed at low power magnification, a basaloid epithelial tumour emerging from the epidermis is the primary characteristic of basal cell carcinoma.
- Normally, the palisade-like basaloid epithelium forms a fissure from the surrounding tumour stroma.
The nuclei grow congested in the centre, with scattered mitotic figures and visible necrotic bodies.
The presence of a mucinous stroma serves as a helpful distinguishing factor from other basaloid cutaneous tumours. Additionally, some tumours may exhibit foci of regression, which are regions of eosinophilic stroma devoid of basaloid nests.
Hence, the answer is a small dome-shaped lesion with a pearly surface on the face.
