    Original Images:
    This article type is intended to provide readers with novel and clinically relevant images of unusual or striking examples of clinical entities, laboratory/radiological studies, or therapeutic procedures with brief explanatory text. The figure can be a single image or no more than 2 related images (eg, a composite showing Figure 1A and 1B). Each image should be of high quality in terms of features such as exposure, focus, color, and contrast. The figure should have a simple descriptive title and a brief legend that includes relevant technical details and explains all labeled structures. Additional explanatory text, which is not part of the legend and ideally should not duplicate the legend, should be limited to 300 words or less and should present relevant clinical information succinctly, such as a short, deidentified description of a patient and/or the patient’s history, relevant physical and laboratory findings, clinical course, response to treatment (if any), and/or condition at last follow-up. Please check Table 1 for the limitations for articles.

    Invited Commentary:
    An invited commentary is a short article that describes an author’s personal experience of a specific topic. Unlike a review article, the author gives his own opinions and perspectives. It typically addresses a current, hot and often controversial subject. It may take two formats, namely, provide an expert author’s personal views of and insight into a current hot topic, or add balance to another paper being commented upon, with addition of the author’s own perspective.

    What is Your Diagnosis?:
    These articles are related with diseases that are seen rarely and show differences in diagnosis and treatment, and they are prepared as questions-answers.
    Content: - Titles related with subject - References (between 3 and 5)

    Medical Book Reviews:
    Reviews and comments on current national and international medical books.

    Questions and Answers:
    Scientific educational questions and answers on medical topics.
