    My brother had terrible eczema as a child, to the point where we would ask him if he wanted to wear shorts in the summer, and he would say “No, thanks.”' I promised myself that I would one day help kids like him. I am proud to have achieved double board certification in pediatrics and dermatology. I feel like a detective when I see a child with a new skin problem; I like to work with families to solve the mystery and figure out how to make my patient feel better.

    I am married to a wonderful woman, and we have three adopted boys from Colombia, five cats, and a house full of craziness and love. My kids are the hardest and best part of my day, every day, and seeing them grow and mature into young men makes me grateful to be alive. They are my heart and my soul, and I have no words for that kind of blessing. I have always appreciated the laughter and spontaneity of children, their sweetness, their complexity, and their straightforward way of just trying to get the most fun possible out of life. I really enjoy keeping kids smiling and happy. I was recently invited to the 10-year cancer free anniversary party of one of my patients. What joy to see him grow. That helps keep me going. I am also passionate about our bone marrow transplantation program, both for children with cancer and for children with non-oncologic disease. When I was in college, I had a chance to work in a rural Mexico clinic as a translator. I was inspired by the physicians – they worked so hard, with so little, and made a huge difference for people who had no other chance. Today I enjoy helping families who need Spanish to communicate with their physician. Dr. Powell is rated as an Experienced provider by MediFind in the treatment of Histiocytosis.

    I grew up in the New York City area. As a child, I was something of a science geek. I enjoyed applying what I learned to real life situations. As a pediatric cancer specialist, I always focus on helping kids with cancer and brain tumors enjoy the best possible quality of life. I have tremendous respect for the children in my care. Although most are very sick, they handle adversity amazingly well. They don’t complain and just want to be done with treatment so they can go on with their lives. I try to make a difference through hope and healing. The fact that Nemours is so active in cancer research means we have access to experimental treatment options that offer real hope for a cure. Just as important, we do everything we can to make a terrible process less terrible by alleviating any suffering.

    I have always loved science and medicine and knew from an early age that I wanted to be in medicine. It is one of the greatest privileges to care for patients and help their families during their cancer treatment. I have always known that I wanted to work with children. Even when dealing with sickness, children have this uncanny ability to find the humor and positivity in all situations. I am passionate about taking the very best care of children and their families in every single interaction I have with them. I am passionate in continuing to improve the care and outcomes of children with cancer and blood disorders through clinical trials and research. I have a particular interest in treating children with leukemia and want to make improvements in every aspect of their care through clinical trials.I also have an interest in improving patient care and clinical research by finding innovative uses of the electronic health record to collect data about how patients are doing on treatment. I also focus on improving the safe delivery of chemotherapy medications. Dr. Gresh is rated as an Experienced provider by MediFind in the treatment of Histiocytosis.

    I'm a pediatric hematologist and oncologist, and an assistant professor at the Sidney Kimmel Medical College. I primarily treat kids with non-malignant hematologic disorders and serve on various committees advocating for patients with hematologic diseases. I always wanted to work with kids and their families and to be able to provide good medical care to people of various backgrounds. I think working with kids and other pediatricians is one of the more enjoyable parts of life. I want to advocate on my patients and families’ behalf and to give them the best care possible. I'm most passionate about non-malignant hematologic disease. In particular I focus on immunohematology and care for patients with sickle cell disease, and I have a particular interest in reproductive health for patients with sickle cell disease, as well as metalogic disorders. I take care of dysfunctional uterine bleeding due to bleeding disorders such as Willebrand disease. I take care of patients with iron deficiency anemia with immune-mediated thrombocytopenias and other immune mediated cytopenia. Throughout my care, I make a point to be present with each patient and family when I'm with them, to make sure that they are heard and advocated for.

    What is the definition of Histiocytosis?

    Histiocytosis is a general name for a group of disorders or "syndromes" that involve an abnormal increase in the number of specialized white blood cells that are called histiocytes.

    Recently, new knowledge about this family of diseases has led experts to develop a new classification. Five categories have been proposed:

    • L group -- includes Langerhans cell histiocytosis and Erdheim-Chester disease
    • C group -- includes non-Langerhans cell histiocytosis that involves the skin
    • M group -- includes malignant histiocytosis
    • R group -- includes Rosai-Dorfman disease
    • H Group -- includes hemophagocytic lymphohistiocytosis

    This article focuses only on the L group, which includes Langerhans cell histiocytosis and Erdheim-Chester disease.

    When should I see a Histiocytosis doctor in Delaware, US?

    There are various reasons why you may want to see a specialist, such as: 

    • Your primary care provider recommends it. 
    • Your condition requires expert knowledge and specialized care. 
    • Your symptoms persist or worsen despite treatment. 
    • You need specialized testing or procedures. 
    • You want a second opinion.  

    What should I consider when choosing a Histiocytosis doctor in Delaware, US?

    It’s important to see a provider with expertise in your specific condition. Each provider profile in MediFind’s doctor database includes information on which conditions they treat, years of experience, research contributions, languages spoken, insurance plans accepted, and more.  

    How does MediFind rank Histiocytosis doctors in Delaware, US?

    MediFind’s rankings are based on a variety of data sources, such as the number of articles a doctor has published in medical journals, participation in clinical trials and industry conferences, as well as the number of patients that provider sees for a given condition. Note that MediFind’s provider database is not based on user reviews, and providers do not pay to be included in the database. 

    What types of insurance are accepted by Histiocytosis doctors in Delaware, US?

    Most profiles in MediFind’s doctor database include a list of insurance plans accepted by that provider. However, it’s a good idea to contact the provider’s office to make sure they still accept your insurance, then doublecheck by contacting your insurance plan to confirm they’re in network. 

    How can I book an appointment online with a Histiocytosis doctor in Delaware, US?

    MediFind offers direct scheduling for certain providers using the “Request Appointment” button on that provider’s profile. If the schedule option is not available for a provider, tap the red “Show Phone Number” button on their profile to get their contact information. If you prefer to find providers who offer online scheduling, select “Schedules online” under the “Availability” category of the filter feature on the left side of the Histiocytosis doctor search results page. 

    Why is it important to get a second opinion from a different Histiocytosis doctor?

    Second opinions are an opportunity to confirm a diagnosis and its root cause, learn about alternative treatment options, or simply gain peace of mind. Many people, especially those with serious diagnoses, get second opinions so they can understand all their options and make informed decisions, so don’t hesitate to get one if you have any doubts or need more information or clarification regarding your care. Note that some insurance plans require second opinions, while others don’t cover second opinions, so be sure to confirm with your insurance provider first.   

    How can I prepare for my appointment with a Histiocytosis doctor in Delaware, US?

    Prepare for your appointment by gathering the following items: 

    • Copies of medical records (dating back at least one year) 
    • Your medical history, including illnesses, medical conditions, surgeries, and other doctors you see 
    • Family history of disease 
    • List of current prescription drugs, over-the-counter medicines, vitamins, and herbal remedies or supplements including names and doses 
    • Allergies to medications, food, latex, insects, etc.  
    • List of questions and concerns 
    • Your insurance card 

    You might also contact the provider’s office to see if they offer transportation or childcare services or if you’re allowed to bring a loved one for support or to take notes during your visit. 

    What questions should I ask my Histiocytosis doctor?

    Here are some sample questions: 

    • Can you explain in simple terms what this condition is and how it’s treated? 
    • What symptoms or side effects should I watch for? 
    • What tests will be involved, and when can I expect results? 
    • Are there other specialists I need to see? 
    • What’s the best way to reach you if I have follow-up questions? 

    How can I learn about the latest clinical trials and research advances my Histiocytosis doctor may know about?

    MediFind’s Clinical Trials tool asks you a series of questions to help you narrow down your search by health condition, age, gender, location, how far you’re willing to travel, and more. Each question you answer filters down the number of trials until you find the ones that are most relevant to you. 

    MediFind’s Latest Advances tool features summaries of recent articles published in medical journals. We use cutting-edge technology to scour medical publication databases for the latest research advancements on any given condition, then we simplify this information in a way that’s useful and easy to understand. 

    Can I filter my search to show male or female Histiocytosis doctors in Delaware, US?

    Look for the filter feature on the left side of the Histiocytosis doctor search results page. Select “Female” or “Male” under the “Gender” category to search for female or male providers exclusively. If the “Any” option is selected, it will pull results for both male and female providers. 

    Can I filter my search to find a Histiocytosis doctor that offers video calls?

    Look for the filter feature on the left-side of the Histiocytosis doctor search results page. Select “Offers telehealth visits” under the Availability category to search for providers who offer virtual appointments (video calls).
