Background: Basal cell carcinoma usually occurs in sun exposed areas of older male individuals.
Objectives: To emphasize the importance of histological step sections in the pursuit of the correct diagnosis when microscopic findings do not correspond to clinical hypothesis.
Patient: 21-year-old female with a superficial basal cell carcinoma in pubic region diagnosed after histological step sections and treated with topical imiquimod.
Conclusions: Although very rare, basal cell carcinomas do occur in young patients and, at times, on areas of the body where they are not conventionally seen. Step sections are an important tool that dermatopathologists should use on a regular basis to enhance diagnostic accuracy.
