Bone marrow involvement by Hodgkin lymphoma is rare with an average incidence of 10%. However, the incidence of bone marrow involvement has been shown to be less than 1% in patients with clinical stage IA or IIA disease. The involvement of the marrow in a patient with Hodgkin lymphoma represents stage IV disease. We report our experience wherein three cases of marrow involvement were picked up on bone marrow aspirates/ -imprints and confirmed on trephine biopsy. In this paper we wish to highlight the significance of bone marrow examination in the initial diagnosis and staging of even clinically early stage Hodgkin lymphoma. Staging investigations performed at the time of diagnosis for patients with Hodgkin lymphoma are vital for determining the appropriate treatment and prognosis.

| > Introduction|| |
Hodgkin lymphoma (HL) is a malignant neoplasm of the lymphoid tissue found in the lymph nodes, spleen, liver, bone marrow, and other sites. Infiltration of the bone marrow at the time of diagnosis is rare, usually focal, and almost always associated with extensive disease, systemic symptoms, and unfavorable histology.
Here we report a case of HL which was diagnosed on bone marrow aspirate (BMA). In the second case, a diagnosis of HL was made based on BMA findings and subsequent fine needle aspirate cytology of cervical lymph node. We also present a case wherein bone marrow infiltration was picked up on bone marrow imprint smear itself thereby helping in the early detection of stage IV disease.

A 19-year-old girl presented with 3 month history of low grade fever and evening rise in temperature. She also gave a history of significant weight loss, malaise, and lassitude. On physical examination, she had severe pallor and a single, non-matted, non-tender 1.5 × 1.0 cm left cervical lymph node of firm consistency. There was no organomegaly, no bony tenderness, or any other systemic examination findings. Routine blood investigations revealed pancytopenia with hemoglobin of 52 g/L, total leukocyte count (TLC) of 1.2 × 10 9 /L, and platelet count (PC) of 83 × 10 9 /L. A concurrent bone marrow aspiration and biopsy followed by a lymph node biopsy were done as a work up for pancytopenia and pyrexia of unknown origin. BMA revealed a cellular marrow with few large binucleate cells having moderate cytoplasm and prominent nucleoli suggestive of Reed Sternberg (RS) cells [Figure 1] in a polymorphous background. A diagnosis of HL was rendered. The bone marrow biopsy (BMB) showed cellular marrow composed of neutrophils, lymphocytes, eosinophils, plasma cells, RS cells, and also few epithelioid granulomas [Figure 2]. The diagnosis of HL was confirmed. The lymph node biopsy revealed HL- mixed cellularity. Immunohistochemistry done on the lymph node biopsy showed CD 15 and CD 30 positivity in the neoplastic cells. The patient was started on chemotherapy and she is currently in remission.

A 55-year-old male presented with 6 month history of low grade fever and evening rise in temperature. He also gave history of weight loss along with on and off cough. On physical examination, he had pallor and a single, discrete, non-tender 1.8 × 1.5 cm right cervical lymph node of firm consistency. There was no organomegaly, no bony tenderness, or any other systemic examination findings. Routine blood investigations revealed hemoglobin of 86 g/L, TLC of 4.2 × 10 9 /L, and PC of 155 × 10 9 /L. His erythrocyte sedimentation rate (ESR) was 68 mm at the end of 1 h. A concurrent BMA and BMB followed by fine needle aspiration cytology (FNAC) of the lymph node were done to rule out tuberculosis and evaluate for pyrexia of unknown origin. BMA revealed a cellular marrow with occasional RS cells and mononuclear forms in a polymorphous background. A diagnosis suggesting the possibility of HL was offered. The FNAC of lymph node offered a diagnosis suspicious of HD. BMB confirmed the involvement by HL. On histological examination of the lymph node biopsy, a final diagnosis of HL- mixed cellularity was put forward and confirmed by immunohistochemistry.
A 28-year-old male with history of fever of one month duration had left cervical and bilateral axillary lymphadenopathy on examination. He also had mild hepatosplenomegaly (liver 2 cm, spleen just palpable). The routine hemogram showed hemoglobin of 138 g/L, TLC of 4.3 × 10 9 /L, and PC of 280 × 10 9 /L. The lymph node biopsy showed HL-lymphocyte predominant. Immunohistochemistry done on the lymph node biopsy showed the neoplastic cells were CD 15 and CD 30 positive. BMB was performed for staging of the disease. The imprint smears revealed a cellular marrow with typical RS cells. BMB confirmed involvement of the bone marrow by HL.
| > Discussion|| |
HL involving the bone marrow is rare, ranges between 2% to 32% with an average incidence of 10%.  However, the incidence of bone marrow involvement has been shown to be less than 1% in patients with clinical stage IA or IIA disease.  The involvement of the marrow in a patient with HL represents stage IV disease. Thus, staging investigations performed at the time of diagnosis for patients with HL are considered crucial for determining the appropriate treatment and prognosis.
Trephine biopsy, usually unilateral is the recommended method to evaluate bone marrow involvement. The value of this procedure is however controversial. BMB is more frequently performed by clinical hematologists than oncologists in the United Kingdom.  In addition, there is little consensus about the impact of bone marrow infiltration on prognosis. , Even, when the bone marrow is involved, it is extremely rare for the tumor cells to be detected in the BMA. The higher sensitivity of the trephine biopsy in the detection of metastatic neoplasms including HL has been reported in recent studies. [1,2] Certain authors envisage that BMA has a minimal role, if any, in detecting involvement of bone marrow by HL. ,,,, The focal pattern of infiltration may be the cause for negative bone marrow aspiration. They advocate that clinical stage IA and IIA patients do not need bone marrow examination.
HL is sometimes diagnosed from trephine biopsy histology.  The presence of RS cells which were detected in the aspirates and imprints of our patients suggest the possibility of early detection and diagnosis of HL especially in patients presenting with pyrexia of unknown origin and cytopenias. Thus, the concept of abandoning bone marrow aspiration and biopsy in early stage HL needs to be revised as suggested by some authors. ,,
The trephine biopsy and histopathological evaluation play a vital role in uncovering marrow involvement by HL. Although reports of neoplastic cells in BMAs are rare, our cases stress the value of aspirates and imprints especially when a diligent assessment of the smears is combined with high index of suspicion.
