Table 3.
Anatomical distribution of BCC subtypes in commonly sun-exposed body sites (n = 643)*
| Histopathologic subtype | Nodular | Sclerodermiform | Superficial | Other | No data available | All |
|---|---|---|---|---|---|---|
| Capillitium | 29 (7.2%) | 15 (10.3%) | 0 | 2 (6.5%) | 4 (11.1%) | 50 (7.8%) |
| Face | 335 (83.1%) | 110 (75.9%) | 9 (32.1%) | 23 (74.2%) | 19 (52.8%) | 496 (77.1%) |
| Lip | 3 (0.7%) | 4 (2.8%) | 1 (3.6%) | 1 (3.2%) | 1 (2.8%) | 10 (1.6%) |
| Neck | 12 (3.0%) | 5 (3.5%) | 1 (3.6%) | 1 (3.2%) | 2 (5.6%) | 21 (3.3%) |
| Back of hand | 2 (0.5%) | 0 | 1 (3.6%) | 0 | 1 (2.8%) | 4 (0.6%) |
| Forearm outside | 3 (0.7%) | 2 (1.4%) | 0 | 0 | 3 (8.3%) | 8 (1.2%) |
| Décolleté | 19 (4.7%) | 9 (6.2%) | 16 (57.1%) | 4 (12.9%) | 6 (16.7%) | 54 (8.4%) |
| Total | 403 (100%) | 145 (100%) | 28 (100%) | 31 (100%) | 36 (100%) | 643 (100%) |
* Pearson’s chi-squared test showed a significant association between body sites classified into head (capillitium/face/lip) versus the remaining body sites and BCC subtypes (nodular, sclerodermiform and superficial), X2 (2) = 75.3651, p < 0.001
