Histological types of malignancy

Histological types of malignancy

A malignant tumour showing features of epithelial di ff erentia - tion, and typically arising in an epithelial layer, is a carcinoma. Other important types of malignancy include malignant mela - noma (melanocytes) ( Figure 11.13b ), lymphoma (lymphoid cells) and sarcoma (mesenchymal cells). Further subclassification is often appropriate and necessary . F or example , categories of carcinoma include squamous cell carcinoma (with evidence of keratinisation) ( Figure 11.15 ), adenocarcinoma (with evidence of glandular di ff erentiation and/or mucin production) ( Figure 11.16 ) or neuroendocrine carcinoma ( Figure 11.13a ) (usually requiring immunohistochemical confirmation of neuroendo - crine di ff erentiation). Some carcinomas have a pattern that raises a certain di ff erential diagnosis, e.g. clear cell carcinoma ( Figure 11.17 ). There are many other morphological types of carcinoma.
