ICD-11 code 2A90.A refers to anaplastic large cell lymphoma that is ALK-positive. This specific type of lymphoma is characterized by the presence of an abnormal fusion protein known as anaplastic lymphoma kinase (ALK). ALK-positive anaplastic large cell lymphoma is a rare subtype of non-Hodgkin lymphoma that primarily affects lymph nodes.
Patients with ALK-positive anaplastic large cell lymphoma often present with enlarged lymph nodes, fever, weight loss, and night sweats. The abnormal ALK protein drives the growth of cancer cells in this type of lymphoma, making it an important factor in the diagnosis and treatment of the disease. Treatment for ALK-positive anaplastic large cell lymphoma may involve a combination of chemotherapy, targeted therapy, and stem cell transplant.

The Centers for Medicare and Medicaid Services (CMS) have not yet set a specific date for the transition to ICD-11.
The situation in Europe varies by country. Some European nations are considering the adoption of ICD-11 or are in various stages of planning and pilot studies. However, as with the U.S., full implementation may take several years due to similar requirements for system updates and training.
🔎 Symptoms
Symptoms of 2A90.A (Anaplastic large cell lymphoma, ALK-positive) typically manifest in the form of enlarged lymph nodes, which may be painless or tender to the touch. This enlargement is often noticeable in the lymph nodes of the neck, armpits, or groin. Furthermore, individuals may experience symptoms such as fatigue, unexplained weight loss, night sweats, and fever.
Additionally, patients with Anaplastic large cell lymphoma, ALK-positive, may develop skin lesions or red, itchy rashes. These skin manifestations can vary in appearance, ranging from papules or nodules to ulcerated lesions. Skin involvement in this type of lymphoma can occur in various areas of the body and may be accompanied by itching or discomfort.
Moreover, individuals affected by 2A90.A may present with systemic symptoms, such as generalized malaise, decreased appetite, and a sense of overall unwellness. These nonspecific symptoms can be indicative of the underlying disease process and warrant further evaluation by healthcare professionals. It is crucial for individuals experiencing such symptoms to seek medical attention promptly for a thorough assessment and appropriate management of Anaplastic large cell lymphoma, ALK-positive.
🩺 Diagnosis
Diagnosis of Anaplastic large cell lymphoma, ALK-positive (2A90.A) typically involves a combination of clinical evaluation, imaging studies, and laboratory tests. A thorough medical history is essential for identifying any potential risk factors or symptoms associated with the disease. Physical examination may reveal enlarged lymph nodes, skin lesions, or other signs of lymphoma.
Imaging studies such as CT scans, PET scans, and MRIs are often used to assess the extent of disease and identify areas of involvement. These scans can help determine the size and location of tumors, as well as detect any spread to other organs or tissues. Additionally, bone marrow biopsy may be performed to assess for the presence of lymphoma cells in the bone marrow.
Laboratory tests play a crucial role in the diagnosis of ALK-positive Anaplastic large cell lymphoma. Blood tests, including complete blood count, liver function tests, and lactate dehydrogenase levels, can provide information about the overall health of the patient and help detect any abnormalities associated with lymphoma. Immunohistochemistry and flow cytometry are used to identify specific markers on lymphoma cells, including the ALK protein, which is characteristic of this subtype of ALCL. Ultimately, a definitive diagnosis of ALK-positive Anaplastic large cell lymphoma is made based on a combination of clinical findings, imaging studies, and laboratory tests.
💊 Treatment & Recovery
Treatment for Anaplastic Large Cell Lymphoma (ALCL) that is ALK-positive typically consists of a combination of chemotherapy and radiation therapy. Chemotherapy drugs such as cyclophosphamide, doxorubicin, vincristine, and prednisone are commonly used to target and destroy cancer cells.
In cases where the cancer has not responded to initial treatment, stem cell transplantation may be considered. This procedure involves replacing the patient’s diseased bone marrow with healthy stem cells, which can help the body produce new, healthy blood cells.
In some instances, targeted therapy drugs may be used to specifically target the ALK protein, which plays a key role in the growth and survival of ALK-positive ALCL cells. These drugs work by inhibiting the action of the ALK protein, thereby slowing down or halting the growth of cancer cells.
🌎 Prevalence & Risk
The prevalence of 2A90.A (Anaplastic large cell lymphoma, ALK-positive) varies across different regions of the world. In the United States, ALK-positive ALCL accounts for approximately 10-15% of all cases of ALCL, making it a relatively rare subtype of the disease. However, this proportion may vary depending on the region and demographic characteristics of the population.
In Europe, the prevalence of ALK-positive ALCL is similar to that of the United States, with approximately 10-15% of ALCL cases being ALK-positive. Like in the United States, the prevalence may differ between countries and populations within Europe. This lymphoma subtype is typically more common in adolescents and young adults, but can also occur in older individuals.
In Asia, the prevalence of ALK-positive ALCL is reported to be slightly higher than in Western countries, with some studies suggesting that up to 20% of ALCL cases are ALK-positive. The reasons for this higher prevalence in Asia are not completely understood, but may be related to genetic or environmental factors. It is important for healthcare providers in Asia to be aware of the relatively higher prevalence of ALK-positive ALCL and consider this subtype in their diagnostic and treatment strategies.
In Australia, the prevalence of ALK-positive ALCL is similar to that of the United States and Europe, with approximately 10-15% of all ALCL cases being ALK-positive. Healthcare providers in Australia should be knowledgeable about the characteristics of ALK-positive ALCL and be prepared to diagnose and manage this subtype of the disease in their patient populations.
