Particulars of the patient
A case report….• Mr. Humayun Kabir, a married man of 35 years old, resides in Mymensingh, has
referred to the Haematology department of this hospital from a private clinic with a diagnostic dilemma ,whose chief complaints were -
• Fever (High grade ; usually at night)
• With Night sweat,
• Productive cough & moderate respiratory distress,
• Pallor & generalized fatigability,
• Sore throat & anorexia,
• Multiple nodular swellings in neck, axilla & groin,
• Mild to moderate Pain in the center of abdomen & feeling of a mass near Left flank
• He has been suffering from all these complaints for last 4 months.
History of present illness
According to the patient’s statement he was apparently well 4months back and able to perform his ordinary physical activity, then he developed high grade fever, usually got worse at night with night sweats & the highest recorded temperature was 103⁰F, . He also complaints of gradual pallor appearance with generalized fatigability, at the beginning weakness and fatigue ness were associated with exertion but now a days he got exhausted even after ordinary physical activity. He has sore throat & has lost appetite and subsequently he has lost weight by apprx. 10 kg by last 4 months. He also found multiple painless nodular swellings in neck, axilla & inguinal regions which are nodular, painless, firm in consistency and a mass near his left flank for the same period. He was transfused >15 units of fresh whole blood by last 4months. He was admitted in a private clinic at first later referred to our hospital. With all these complaints he has got admitted in DMCH for further evaluation and better management.
History of past illness: No significant past medical history
Immunization history: Immunized as per EPI scheduleFamily history: He is the1st issue of his parents. Other
sib are normal & has no history of such type of disease Personal history: Non-smoker and no other bad habitsSocioeconomic condition: He belongs to middle class
familyDrug history: Not allergic to any kind of drug. He took
chemotherapy (ABVD regimen), oral antibiotic and antipyretic for his illness.
Transfusion History: He received >15 units of fresh whole blood by last 4 months.
History of past illness
His circumcision was uneventful. He had no history of skin rash, painful joint swelling or prolonged bleeding after minor trauma before this illness.He was normotensive, non diabetic, non asthmatic. He had no history of tuberculosis, contact with TB patient or no history jaundice & hepatitis.
• He was transfused with several units of fresh whole blood but in vain.
• Initially lymph node (from axillary lymph node) biopsy report infers as Hodgkin’s disease, hence he received 2 cycles of ABVD regimen D1 & D21.
• Later review of the same slide revealed as NHL and he has been given CHOP-14 regimen as treatment protocol because of highly aggressive nature of the tumor.
• So, there is a diagnostic dilemma while hematologist and the pathologist are stick to their diagnosis.
• So immunohistochemistry (CD 3, LCA, CD 20) was sent and reports negative.

Pathogenesis of AIHA
Autoimmune diseases are characterized by loss of tolerance to self antigens and include a broad variety of conditions like autoimmune hemolytic anemia (AIHA), systemic lupus erythematosus, rheumatoid arthritis, Sjogren’s syndrome, inflammatory bowel disease etc. The concurrence of autoimmune diseases with malignancy is well documented. One such association is AIHA occurring with non-Hodgkin’s lymphoma (NHL). The exact pathogenesis of this association is still speculative. AIHA is relatively uncommon disease and most often idiopathic. NHL arising from lymphoid tissue refers to a heterogeneous group of malignancies with varied clinical and biological features.

Treatment of Lymphoma
Diffuse Large B-Cell Lymphoma (DLBCL) Stage I disease Non-bulky disease and no adverse risk factors (elevated LDH, PS <2) should receive 3-4 cycles of R-CHOP followed by involved site radiotherapy (ISRT)Patients with bulky disease should receive 6-8 cycles of R-CHOP. Radiotherapy should be considered for residual mass at the completion of treatment.
Treatment of Lymphoma
Diffuse Large B-Cell Lymphoma (DLBCL) Stage II-IV Disease Following the GELA study and subsequent NICE guidance, patients with CD20 positive DLCBL stage II-IV disease should now be offered 6-8 cycles of R-CHOP as first line treatment
CHOP vs R-CHOP (3.5 vs 8.4 years)
Treatment of Lymphoma
Follicular Lymphoma Criteria for delaying treatment (GELF17)All of the following:
Maximum diameter of disease 7 cmFewer than 3 nodal sitesNo systemic symptomsSpleen 16 cm on CTNo significant effusionsNo risk of local compressive symptomsNo circulating lymphoma cellsNo marrow compromise

Treatment of Lymphoma
Mantle Cell Lymphoma :Distinct subtype of B-cell NHL. The majority of patients are over the age of 60 usually presenting with advanced stage disease. Conventional CHOP chemotherapy offers 75% overall response rate (ORR), 7% complete response (CR) rate but most patients relapse within 2 years.

Burkitt’s Lymphoma/ALL- L3 :Tumour lysis syndrome is a particular risk High risk of CNS disease/relapse and intrathecal treatment.High-intensity chemotherapy regimens have been developed for Burkitt’s lymphoma resulting in a 60-70% long-term survival rate.
