    Philosophy of care | I believe children are a unique population of patients that require a physician dedicated to their well-being. I believe they are vulnerable and often unable to speak up for themselves. I believe that each child and family should be treated as if they are my own relation. | Why I entered medicine | I entered medicine for the satisfaction of being able to help and offer hope to those who are ill. I chose pediatric hematology oncology because these children have a serious illness and their parents are at the lowest point of their lives, and I can provide them with hope and compassion. | Community involvement | I volunteer at Camp Dost, a camp for children with cancer. Since 2003 I have helped there, and love seeing how this experience helps kids who are dealing with cancer enjoy time just being kids. | Personal interests | I enjoy many types of sports, but specifically like basketball, baseball, football, and golf. I also like to go canoeing and doing physical fitness activities. Dr. Troutman is rated as an Experienced provider by MediFind in the treatment of Histiocytosis.

    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 Pennsylvania, 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 Pennsylvania, 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 Pennsylvania, 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 Pennsylvania, 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 Pennsylvania, 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 Pennsylvania, 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 Pennsylvania, 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).
