==Overview==
Hepatosplenic T cell lymphoma is a rare type of non Hodgkins lymphoma that occurs in states of immunosupression such as post organ transplant and treatment of inflammatory bowel disease. Hepatosplenic T cell lymphoma was discovered by Farcet et al in 1990''.'' It is also known as "gamma-delta" hepatosplenic T-cell lymphoma. The [[lymphoma]] is characterized by malignant [[T-cell proliferation]] in the sinusoids of the liver, sinuses and red pulp of the spleen, and sinuses of the bone marrow. The incidence of hepatosplenic T cell lymphoma is 0.3 per 100000 individuals per year. If left untreated, patients can develop liver failure, pancytopenia or spleen rupture. Biopsy of the tumor is the gold standard diagnostic test for diagnosing hepatosplenic T-cell lymphoma. Chemotherapy including CHOP is the mainstay of the treatment along with [[Bone marrow transplantation|bone marrow transplant]] and radiation therapy.
 
==Historical Perspective==
Hepatosplenic T cell lymphoma was discovered by Farcet et al in 1990''.''
 
==Classification==
There is no established system for the classification of hepatosplenic T cell lymphoma.
 
==Pathophysiology==
* Hepatosplenic T-cell lymphoma is a [[T-cell lymphoma classification|peripheral T-cell lymphoma]], a type of [[Non-Hodgkin lymphoma|non Hodgkin's lymphoma]].<ref name="pmid28516671">{{cite journal| author=Armitage JO| title=The aggressive peripheral T-cell lymphomas: 2017. | journal=Am J Hematol | year= 2017 | volume= 92 | issue= 7 | pages= 706-715 | pmid=28516671 | doi=10.1002/ajh.24791 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=28516671  }} </ref>

* Patients with [[inflammatory bowel disease]] receiving [[immunosuppressants]] and [[Tumor necrosis factor-alpha|anti-tumor necrosis factor-α]] agent are also at risk for developing hepatosplenic T-cell lymphoma.

* Gamma delta T cells represent the first line of defense against [[Bacteria|bacterial]] [[Peptide|peptides]], such as [[Heat shock protein|heat-shock proteins]].
* Gamma delta T cells are [[CD4]] and [[CD8]] negative, but [[CD56]] positive which is [[Natural Killer T cell|NK cell marker]].
* Gamma delta cells respond to a stimulus and are responsible for [[lymphokine]] production and proliferation.
* Gamma delta cells are predominantly located in the [[spleen]], [[liver]] sinusoids and [[Intestine|intestinal]] epithelium.
* 75 % of the cases are of gamma delta phenotype and the rest are apha beta phenotype.
* Chronic antigen stimulation in states of immunosuppression is responsible for the development of the [[lymphoma]].
* [[Isochromosome]] of the long arm of [[chromosome 7]] is a genetic abnormality described in hepatosplenic T cell lymphoma. It could also be in association with [[trisomy]] 8 and a loss of a [[sex chromosome]].
* Mutations in ''[[SETD2]], [[INO80 complex subunit E|INO80]], TET3'' and ''[[STAT5B]]'' occur exclusively in hepatosplenic T cell lymphoma as compared to other T and B cell lymphoma types.
* The lymphoma is characterized by malignant T-cell proliferation in the sinusoids of the liver, sinuses and red pulp of the spleen, and sinuses of the bone marrow.
* Splenic involvement is characterized by diffuse involvement of the [[red pulp]] with small-to-medium-sized [[atypical lymphocytes]].
* The atypical lymphocytes are present within the cords and sinuses of the red pulp.
* There occurs a complete loss of the [[white pulp]].
* The liver also shows sinusoidal infiltration by neoplastic lymphoid cells.
* The bone marrow is characterized by neoplastic cells in the sinusoids.
* Bone marrow infiltration results in [[pancytopenia]].
* The lymphoma cells are typically [[CD2|CD2+]], [[CD3 (immunology)|CD3+]], CD4−, CD5−, CD7+, CD8− CD42+, CD52+, CD76+, CD82+ with either gamma-delta or alpha-beta T-cell phenotypic receptor expression.
* It manifests as [[hepatosplenomegaly]] without peripheral [[lymphadenopathy]].
* [[Pancytopenia]] and abnormal liver functions are the laboratory findings.
* Histology and immunohistochemistry of the tumor biopsy shows portal and sinusoidal infiltration by atypical small-to-medium sized lymphocytes with hyperchromatic nuclei and low mitotic activity.

Overview

Hepatosplenic T cell lymphoma is a rare type of non Hodgkins lymphoma that occurs in states of immunosupression such as post organ transplant and treatment of inflammatory bowel disease. Hepatosplenic T cell lymphoma was discovered by Farcet et al in 1990. It is also known as "gamma-delta" hepatosplenic T-cell lymphoma. The lymphoma is characterized by malignant T-cell proliferation in the sinusoids of the liver, sinuses and red pulp of the spleen, and sinuses of the bone marrow. The incidence of hepatosplenic T cell lymphoma is 0.3 per 100000 individuals per year. If left untreated, patients can develop liver failure, pancytopenia or spleen rupture. Biopsy of the tumor is the gold standard diagnostic test for diagnosing hepatosplenic T-cell lymphoma. Chemotherapy including CHOP is the mainstay of the treatment along with bone marrow transplant and radiation therapy.

Historical Perspective

Hepatosplenic T cell lymphoma was discovered by Farcet et al in 1990.

Classification

There is no established system for the classification of hepatosplenic T cell lymphoma.

Pathophysiology

  • Hepatosplenic T-cell lymphoma is a peripheral T-cell lymphoma, a type of non Hodgkin's lymphoma.[1]
  • It is also known as "gamma-delta hepatosplenic T-cell lymphoma".[2]
  • It usually occurs in young men with history of immunosuppression including solid organ transplantation.[3]
  • Patients with inflammatory bowel disease receiving immunosuppressants and anti-tumor necrosis factor-α agent are also at risk for developing hepatosplenic T-cell lymphoma.
  • The T-cell receptor consists of either a gamma delta or alpha-beta entity on their cell surface which are a part of the innate immune system.[4][5]
  • Gamma delta T cells represent the first line of defense against bacterial peptides, such as heat-shock proteins.
  • Gamma delta T cells are CD4 and CD8 negative, but CD56 positive which is NK cell marker.
  • Gamma delta cells respond to a stimulus and are responsible for lymphokine production and proliferation.
  • Gamma delta cells are predominantly located in the spleen, liver sinusoids and intestinal epithelium.
  • 75 % of the cases are of gamma delta phenotype and the rest are apha beta phenotype.
  • Chronic antigen stimulation in states of immunosuppression is responsible for the development of the lymphoma.
  • Isochromosome of the long arm of chromosome 7 is a genetic abnormality described in hepatosplenic T cell lymphoma. It could also be in association with trisomy 8 and a loss of a sex chromosome.
  • Mutations in SETD2, INO80, TET3 and STAT5B occur exclusively in hepatosplenic T cell lymphoma as compared to other T and B cell lymphoma types.
  • The lymphoma is characterized by malignant T-cell proliferation in the sinusoids of the liver, sinuses and red pulp of the spleen, and sinuses of the bone marrow.
  • Splenic involvement is characterized by diffuse involvement of the red pulp with small-to-medium-sized atypical lymphocytes.
  • The atypical lymphocytes are present within the cords and sinuses of the red pulp.
  • There occurs a complete loss of the white pulp.
  • The liver also shows sinusoidal infiltration by neoplastic lymphoid cells.
  • The bone marrow is characterized by neoplastic cells in the sinusoids.
  • Bone marrow infiltration results in pancytopenia.
  • The lymphoma cells are typically CD2+, CD3+, CD4−, CD5−, CD7+, CD8− CD42+, CD52+, CD76+, CD82+ with either gamma-delta or alpha-beta T-cell phenotypic receptor expression.
  • It manifests as hepatosplenomegaly without peripheral lymphadenopathy.
  • Pancytopenia and abnormal liver functions are the laboratory findings.
  • Histology and immunohistochemistry of the tumor biopsy shows portal and sinusoidal infiltration by atypical small-to-medium sized lymphocytes with hyperchromatic nuclei and low mitotic activity.

Causes

Common causes of hepatosplenic T cell lymphoma are: [6][7]

Differentiating hepatosplenic T cell lymphoma from Other Diseases

Differential diagnosis for the lymphoma is based on the below table:

Epidemiology and Demographics

  • The incidence of hepatosplenic t cell lymphoma is 0.3 per 100000 individuals per year.
  • It occurs in younger group of patients, most cases falling in 20-40 years of age group.
  • Men are more affected than the females.

Risk Factors

Common risk factors include:

Screening

There is insufficient evidence to recommend routine screening for hepatosplenic T cell lymphoma.

Natural History, Complications, and Prognosis

Natural history

  • Patients have a history of immunosupression such as inflammatory bowel disease under treatment or organ transplant.[103]
  • The mean age group is 35 years and most of the patients are males.
  • Initial symptoms are fever, weight loss, night sweats and then progress to more severe symptoms depending on the organ involvement but there is no lymphadenopathy.
  • Patients also present with symptoms of liver, spleen and bone marrow dysfunction.
  • If left untreated, patients can develop liver failure, pancytopenia, or spleen rupture.

Complications

Prognosis

  • The prognosis is very poor, with patients dying within 2-3 years of diagnosis even after recieving treatment[104].

Diagnosis

Diagnostic Study of Choice

  • Biopsy of the tumor is the gold standard diagnostic test for diagnosing hepatosplenic T cell lymphoma[105].
  • CT scan and PET scan are used to assess the spread of the lymphoma.

Symptoms

The most common symtoms are[106]:

  • Fever
  • Weight loss
  • Night sweats
  • Pain abdomen
  • Jaundice
  • Fatigue
  • Recurrent infections
  • Bleeding

Physical Examination

Temperature

Skin

Thorax

Abdomen

Extremities

Laboratory Findings

  • Biopsy of the tumor:
    • Histology - small-to intermediate sized T lymphocytes infiltrate the sinusoids of the liver and the splenic red pulp.
    • Flow cytometry and immunophenotyping - The lymphoma cells are typically CD2+, CD3+, CD4−, CD5−, CD7+, CD8− CD42+, CD52+, CD76+, CD82+ with either gamma-delta or alpha-beta T-cell phenotypic receptor expression[107].
    • Karyotyping - Isochromosome of the long arm of chromosome 7 is a genetic abnormality described in hepatosplenic t cell lymphoma. It could also be in association with trisomy 8 and a loss of a sex chromosome[108].
  • Bone marrow biopsy; The bone marrow is characterized by neoplastic cells in the sinusoids.
  • Complete blood count; Pancytopenia
  • Liver function tests: Deranged LFT

Electrocardiogram

There are no ECG findings associated with hepatosplenic T cell lymphoma.

X-ray

There are no x-ray findings associated with hepatosplenic T cell lymphoma but pleural effusion might be present.

Echocardiography or Ultrasound

  • There are no echocardiography findings associated with hepatosplenic T cell lymphoma.
  • On ultrasound of abdomen:

CT scan

Tumor mass can be seen in liver or spleen or both.

MRI

Tumor mass can be seen in liver or spleen or both.

Other Imaging Findings

PET scan: On PET scan, tumor mass can be seen in liver or spleen or if it has metastasized to any other organ.

Treatment

Medical Therapy

Surgery

Surgical intervention is not recommended for the management of hepaosplenic T cell lymphoma.

Primary Prevention

There are no established measures for the primary prevention of hepatosplenic T cell lymphoma.

Secondary Prevention

There are no established measures for the secondary prevention of hepatosplenic T cell lymphoma.
