A prevalent form of classic Hodgkin's lymphoma, MCHL is most commonly seen in children who have previously had an Epstein-Barr virus infection or in adults who are HIV positive. Its outlook is typically positive.
Differential cellularity One kind of cancer that begins in the lymphatic system is called Hodgkin's lymphoma (MCHL). About 4 out of 10 instances of classic Hodgkin's lymphoma are of this kind, which is the second most frequent.
Hodgkin's lymphoma typically begins in B lymphocytes, which are immune system cells that help defend the body against bacteria and viruses by producing antibodies. The lymph nodes, also known as lymph glands, are little lumps of tissue that are home to these B lymphocytes.
The lymph nodes of MCHL are named as such because they harbour a mixture of aberrant cells and very big cells known as Reed-Sternberg (RS) cells.
An overview of MCHL, including its aetiology, risk factors, symptoms, diagnosis, course of treatment, and prognosis, will be given in this article.

What are the symptoms of mixed cellularity Hodgkin’s lymphoma?
Later stages of the cancer are associated with a higher frequency of MCHL symptoms. They could consist of:
- unexplained weight loss
- high fever
- night sweats
- Upper body lymph nodes, especially those in the armpit and neck, are swollen
How do doctors diagnose mixed cellularity Hodgkin’s lymphoma?
MCHL is often diagnosed by a lymph node biopsy. This entails taking a tiny sample of tissue out of the lymph node, ideally by excision but also, if required, with a fine needle. The tissue sample can then be examined under a microscope by a pathologist working in a lab.
Blood tests might also be prescribed by a physician to aid in the diagnosis or exclusion of other illnesses. These could consist of:
- complete blood count
- complete metabolic panel
- erythrocyte sedimentation rate test
- testing for the human immunodeficiency virus (HIV), hepatitis B, and hepatitis C infections
Your doctor can ascertain the cancer's stage and whether it has spread to other areas of the body with the use of imaging tests such as a PET, X-ray, or CT scan.
What is the treatment for mixed cellularity Hodgkin’s lymphoma?
Your general health, the cancer's stage, and other variables all affect how you will be treated for MCHL. Curing the illness is the aim of treatment, which may involve one or more rounds of radiation therapy or chemotherapy.
High-dosage chemotherapy followed by an autologous stem cell transplant or immunotherapy may be used as a treatment if chemotherapy and radiation prove ineffective or if the cancer relapses (resurfaces after treatment).
What is the outlook for people with mixed cellularity Hodgkin’s lymphoma?
For those who have Hodgkin's lymphoma, the prognosis is usually good. Its 5-year relative survival rate is 89%, and its cure rate is 80%. One of the cancers that is currently most treatable is Hodgkin's lymphoma, according to the Leukaemia & Lymphoma Society.
The National Cancer Institute (NCI) states that MCHL has a highly curable prognosis with treatment, similar to that of nodular sclerosis and Hodgkin's lymphoma.
Following treatment, remission is common in MCHL patients. Nevertheless, following an initial remission, up to 30% of patients with Hodgkin's lymphoma will experience a relapse.
What causes mixed cellularity in Hodgkin’s lymphoma?
Although the exact origin of MCHL is unknown, various risk factors, such as HIV and Epstein-Barr virus infections, have been found by researchers (EBV).
According to some experts, these infections may alter B lymphocyte DNA, resulting in the development of Reed-Sternberg cells.
Furthermore, evidence points to a possible hereditary component of Hodgkin's lymphoma development.
Who is at risk of mixed cellularity Hodgkin’s lymphoma?
The majority of MCHL cases are seen in HIV-positive individuals. Additionally, children with a history of EBV infection are more likely to have it.
MCHL risk factors include:
- adults age 55 to 74 years
- children under the age of 10 years
- males
- HIV infection
- EBV infection
Resources for support
Organisations like the Leukaemia & Lymphoma Society and the Lymphoma Research Foundation can provide patient resources, education, emotional support, and help with treatment and rehabilitation if you have been diagnosed with MCHL.
FAQ
What is Hodgkin's lymphoma with mixed cellularity?
Differential cellularity Classic Hodgkin/Reed-Sternberg (HRS) cells on a diffuse mixed inflammatory backdrop characterise classic Hodgkin lymphoma (MCCHL), a subtype of classic Hodgkin lymphoma (CHL). Although capsular fibrosis is typically absent, fibrous brands are absent, and fine interstitial fibrosis may be present.
What are the 4 types of Hodgkin's lymphoma?
The four kinds of classical Hodgkin lymphoma are lymphocyte abundant, lymphocyte deficient, mixed cellularity, and nodular sclerosing. The fifth form, known as nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL), is a distinct entity that requires a different treatment approach in addition to having specific clinical features.
Which type of Hodgkin’s lymphoma has the best prognosis?
The most prevalent kind of classical Hodgkin's lymphoma (CHL), nodular sclerosis, has a good prognosis, particularly when detected and treated early. Compared to other forms of CHL, its survival rate is typically higher.
Takeaway
The second most prevalent subtype of Hodgkin's lymphoma is called MCHL. People with an active HIV infection or a history of EBV infection are most commonly affected by MCHL.
An excellent overall prognosis is associated with MCHL when diagnosed and treated early.
