Basal cell carcinoma is the most common malignant skin tumor, strongly linked to ultraviolet exposure. It often starts on sun-exposed areas—especially the face—with appearances ranging from pearly, vessel-like nodules to persistent, reddish eczema-like patches. As you move through the guide, you’ll see how major subtypes and dermoscopy findings support diagnosis, how personal sun history shapes risk, and how treatment choices influence outcomes and recurrence.
Key Takeaways
- Basal cell carcinoma typically presents as a pearly nodule with telangiectasia on sun-exposed skin, most commonly on the face (80% of cases).
- Nodular BCC subtype accounts for 60-80% of cases, characterized by rolled borders and central ulceration.
- Superficial BCC appears as erythematous patches resembling eczema, comprising 15-20% of BCCs.
- Basal cell carcinoma (BCC) represents about 80% of all malignant skin tumors in whites, with an estimated 3.6 million cases diagnosed annually in the US.
- The incidence rate of BCC in the US has increased by over 10% per year since 1994, reaching 43.6 cases per 100,000 person-years by 2012.
- In Australia, BCC incidence is the highest globally at 1,015 per 100,000 person-years in men and 624 in women aged 60-69.
- Basal cell carcinoma has a 99% 5-year survival rate when detected early and treated appropriately.
- Local recurrence rate for incompletely excised BCC is 39% at 5 years with no further treatment.
- Metastatic BCC occurs in <0.1% cases, with median survival 8-10 months post-metastasis.
- Ultraviolet radiation exposure is the primary risk factor for basal cell carcinoma, responsible for up to 90% of cases in fair-skinned individuals.
- Fair skin (Fitzpatrick types I-II) increases BCC risk by 2-3 fold compared to darker skin types.
- History of severe sunburns before age 20 doubles the lifetime BCC risk.
- Surgical excision with 4mm margins clears 98% of low-risk BCCs (Mohs preferred for high-risk).
- Mohs micrographic surgery achieves 99% cure rate for primary BCC, 94% for recurrent.
- Topical imiquimod 5% cream cures 82-90% superficial BCCs after 6-12 weeks.
Most basal cell cancers are common on sun exposed face skin, and early treatment is highly curable.
