ICD11: -
Keloid basal cell carcinoma, fibrosing basal cell carcinoma, morpheaant basal cell carcinoma, morpheiform basal cell carcinoma, sclerosing basal cell carcinoma.
Clinically "scarring" aspect, with a more pronounced therapeutic approach usually recommended.
Particularly the nose, forehead or cheeks.
A connective tissue, fibromatous reaction surrounds the tumour cell clusters. Unlike other forms of BCC, the typical palisading is mostly absent.

Experimental therapies
- Imiquimod cream 5% daily 5x/week for a total of 6 weeks.
- Useful in superficial and in Gorlin syndrome.
- Laser therapy
- Photodynamic therapy
- Cryotherapy
- Especially infiltrative growing and sclerodermiform basal cell carcinomas should be surgically excised.
- In the case of incomplete resection, re-excision should be performed except in well justified cases.
- Cure rate depends on tumour diameter, histological type and safety margin.
