Langerhans cell histiocytosis historically was thought of as a cancer-like condition, but more recently researchers have begun to consider it an autoimmune phenomenon in which immune cells begin to overproduce and attack the body instead of fighting infection. What treatment options are available for patients with Langerhans cell histiocytosis? The prognosis is more closely related to the disease burden rather than histological features, although frankly malignant features (Langerhans cell sarcoma) do also have an impact on survival 3,4: The Langerhans cell was discovered within the epidermis by German physician Paul Langerhans (1847-1888) in 1865 when he was a medical student and working under famed Professor Rudolf Virchow 9.

Langerhans cell histiocytosis (LCH) is a group of idiopathic disorders characterized by the presence of cells with characteristics similar to bone marrow–derived Langerhans cells juxtaposed against a backdrop of hematopoietic cells, including T-cells, macrophages, and eosinophils. The appearance of new nodules later in the disease (when cystic change is established) indicates disease progression but is a rare finding 3. Langerhans cell histiocytosis (LCH) is the most common of the histiocytic disorders and occurs when the body accumulates too many immature Langerhans cells, a subset of the larger family of cells known as histiocytes.

Langerhans cell histiocytosis historically was thought of as a cancer-like condition, but more recently researchers have begun to consider it an autoimmune phenomenon in which immune cells begin to overproduce and attack the body instead of fighting infection. What treatment options are available for patients with Langerhans cell histiocytosis? The prognosis is more closely related to the disease burden rather than histological features, although frankly malignant features (Langerhans cell sarcoma) do also have an impact on survival 3,4: The Langerhans cell was discovered within the epidermis by German physician Paul Langerhans (1847-1888) in 1865 when he was a medical student and working under famed Professor Rudolf Virchow 9.

Langerhans cell histiocytosis (LCH) is a group of idiopathic disorders characterized by the presence of cells with characteristics similar to bone marrow–derived Langerhans cells juxtaposed against a backdrop of hematopoietic cells, including T-cells, macrophages, and eosinophils. The appearance of new nodules later in the disease (when cystic change is established) indicates disease progression but is a rare finding 3. Langerhans cell histiocytosis (LCH) is the most common of the histiocytic disorders and occurs when the body accumulates too many immature Langerhans cells, a subset of the larger family of cells known as histiocytes.

Langerhans cell histiocytosis historically was thought of as a cancer-like condition, but more recently researchers have begun to consider it an autoimmune phenomenon in which immune cells begin to overproduce and attack the body instead of fighting infection. What treatment options are available for patients with Langerhans cell histiocytosis? The prognosis is more closely related to the disease burden rather than histological features, although frankly malignant features (Langerhans cell sarcoma) do also have an impact on survival 3,4: The Langerhans cell was discovered within the epidermis by German physician Paul Langerhans (1847-1888) in 1865 when he was a medical student and working under famed Professor Rudolf Virchow 9.

Langerhans cell histiocytosis (LCH) is a group of idiopathic disorders characterized by the presence of cells with characteristics similar to bone marrow–derived Langerhans cells juxtaposed against a backdrop of hematopoietic cells, including T-cells, macrophages, and eosinophils. The appearance of new nodules later in the disease (when cystic change is established) indicates disease progression but is a rare finding 3. Langerhans cell histiocytosis (LCH) is the most common of the histiocytic disorders and occurs when the body accumulates too many immature Langerhans cells, a subset of the larger family of cells known as histiocytes. Hann IM, Smith OP. Langerhans cell histiocytosis. 27 (6): 1272-85.

What treatment options are available for patients with Langerhans cell histiocytosis? The prognosis is more closely related to the disease burden rather than histological features, although frankly malignant features (Langerhans cell sarcoma) do also have an impact on survival 3,4: The Langerhans cell was discovered within the epidermis by German physician Paul Langerhans (1847-1888) in 1865 when he was a medical student and working under famed Professor Rudolf Virchow 9.
