Overview
There is no well established classification for basal cell carcinoma, however there are few clinical variants which are nodular, cystic, sclerodermiform, infiltrated, micronodular, superficial, and pigment basal cell carcinoma and fibroepithelioma of Pinkus.
Basal Cell Carcinoma Classification
- There is no well established classification for the basal cell carcinoma of the skin[1][2]
- However based on some evidence there are few clinical variants of basal cell carcinoma, the following table summarizes the classification of the clinical variants of basal cell carcinoma (BCC):
| Clinical Variants | Description |
| Nodular BCC | Comprises about 60-80% of cases; most commonly found on the skin of the head; clinically: elevated, exophytic pearl-shaped nodules with telangiectasias on the surface and periphery; histologically: nest-like infiltration from basaloid cells |
| Cystic BCC | ≥ 1 cystic node with different sizes located peripherally to the centrally placed tumor nests |
| Sclerodermiform (morpheiform) BCC | The tumor cells are surrounded by fibrotic stroma; clinically: infiltrated plaque with a slightly shining surface and not well-defined borders; immunochemistry: expression of smooth muscle alpha-actin |
| Infiltrated BCC | Most common found on the upper part of the trunk or face; clinically: whitish, compact, not well-defined plaque; histologically: thin, nest-like bundles of basaloid cells infiltrating in the dermal collagenous fibers |
| Micronodular BCC | Most commonly found on the skin of the back; clinically: may be flat or elevated; yellow-whitish color when flat, clear outlines and thick at palpation; histologically: small rounded nodules of basaloid cells and minimal palisading |
| Superficial BCC | Comprises about 10-30% of cases; clinically: erythematous squamous plaque with clear borders, pearl-shape edge, superficial erosion, without tendencies for invasive growth; histologically: nests of basaloid cells located subepidermally, connection with the basal layer of the epidermis and no infiltration of tumor cells in the reticular dermis |
| Pigment BCC | The color varies from dark brown to black; clinically: nodular, micronodular, multifocal, superficial; histologically: nests of basaloid cells, melanocytes and melanophages, moderate inflammatory infiltrate |
| Fibroepithelioma of Pinkus | Most commonly on the skin of the back; affects women especially; clinically: elevated pink or erythematous nodules; histologically: trabecular, elongated, and branched thin strands of basaloid cells |
