Case studies are generally a single-case design, but can also be a multiple-case design, where replication instead of sampling is the criterion for inclusion.

In medicine, a case report is a detailed report of the symptoms, signs, diagnosis, treatment, and follow-up of an individual patient. Case reports may contain a demographic profile of the patient, but usually describe an unusual or novel occurrence. Some case reports also contain a literature review of other reported cases.
