Can basal cell carcinoma develop on the site of a healed gumma?

Syphilitic gummas have become exceedingly rare in present practice. Approxi mately one-third of untreated cases of syphilis result in tertiary syphilis which can be subdivided into benign syphilis (gumma), cardiovascular syphi lis or neurosyphilis. Gumma represents an inflammatory process and heals wi th scarring. It can heal spontaneously but recurrence in untreated or inade quately treated cases can occur in the same or another site. Resolution is prompt under treatment, although recurrence is not inevitable. We report an interesting case of basal cell carcinoma (BCC) that developed at the site of a previous gumma and discuss the possibility of a causal association bet ween both conditions.
