This app is intended to help you interpret the dermoscopic patterns seen with your dermatoscope. You will be asked a series of questions that will lead you to the most probable diagnosis. This app also contains over 80 photos and charts to help you in your diagnosis. No internet connection needed to view the full app. It is all ready for super quick image and information retrieval. There are also 50 interactive cases to solve. Each case starts with a clinical and dermoscopic image and ends with a labelled dermoscopic image pointing out critical structures. This app is based on the 2 step algorithm with the first step involving the determination of whether the lesion is a melanocytic. Melanocytic lesions will be divided into nevi or lesions with varying levels of suspicion for melanoma based on melanoma specific patterns and common nevi patterns. Non-melanocytic lesions will be analyzed to determine if they are suspicious for basal cell carcinoma or squamous cell carcinoma. Common benign lesions such as dermatofibroma, seborrheic keratoses and hemangiomas will be positively identified to avoid unnecessary biopsies. This app will increase your ability to detect skin cancers with greater accuracy thereby decreasing unnecessary biopsies and missing less early melanomas and nonmelanoma skin cancers.

MedPearl is where medical knowledge meets patient data at the point of care. By empowering clinicians, MedPearl provides what clinicians need to make more accurate and appropriate treatment plans, orders, and referrals – all digestible and specialized knowledge, personalized to their patient’s EMR data. Powered by artificial intelligence, MedPearl speaks to common and difficult clinician treatment decisions within a 2-minute time budget across +650 topics and as we hope to be at 1,000 by the end of the year. Medical knowledge does not live in electronic medical records (EMR) and existing clinical decision resources provide excess amount of information that is neither digestible nor actionable within a patient visit. All clinicians are experiencing medical knowledge overload, negatively impact all parties - Primary Care, Urgent Care, other Specialists, and our Patients. MedPearl provides clinicians with its extensively researched and peer reviewed (by team of specialists, primary care, and urgent care physicians) guides and algorithms, exposing only the information a clinician needs to make right decision for the patient at hand. MedPearl integrates with any EMR. The patient data surfaced in the EMR is never stored in MedPearl. “With the demand for specialty consultation greatly exceeding the supply of specialists widening for the foreseeable future, MedPearl improves access when it has never been more vital” - Medical Group Chief Executive Officer “MedPearl is a gift to our providers, especially those working solo.” – Medical Group Chief Clinical Officer
