When dealing with isolated conditions or common condition with rare presentation, case reports are practically helpful than any other studies.individual case reports will lead us to precision medicine.
Yes, Monika Pathania , I agree; if the case report covers a relatively rare condition / rare presentation. It may be possible to find other cases also reported singly; this then enables the reader to compare / contrast. But if the case reports were not published, this could not take place. In this way, the scientific community are enabling a larger picture to be shown.

The medical integration of scientific methodology and clinical reasoning, e.g. case reports, concerning the hierarchy of evidence, would require a redefinition of best practices. Medicine is mostly a practical discipline by apprenticeship and lacks scientific methodology. The advancement of clinical reasoning in medical education and practice could help to close this methodical and scientific gap.
Stephen I. Ternyik you rightly pointed out, scientific methodology and CLINICAL REASONING ,is the most important . clinical reasoning is strengthened as one matures as a clinician .
Case studies are valuable tools and provide valuable insight. If they are replicated under various conditions, together they will merit even higher importance and help connect the dots leading to a well established methodology.
The point you bring in reagrd to the rare diseases is valid. We still face disorders or rare presentation in which the only evidnce we can dccount for is a case report. The capcacity to cobine them in case series is not easy retrspectivly , but one should encourage publications of theses and journals should be more acceptingf of well written case reports in the situations you mentioed.
The bias of anecdotal medicine may be present in these situations, yet its may be the best we have in the absnce of any alterantive.
