Figure 18.31 A mixture of occult and verrucose sarcoids
Verrucose sarcoids (Figure 18.32)
Verrucose sarcoids resemble the occult type, but the skin is more thickened and irregular.
Sometimes they form dry, wart-like lesions on the skin. They may develop from the occult
sarcoids, so their distribution pattern is similar. If knocked or abraded, they may ulcerate and
develop into a more aggressive, fibroblastic form.
