Hematology/ haematology is the branch of medicine concerned with the study of the cause, prognosis, treatment, and prevention of diseases related to blood. It involves treating diseases that affect the production of blood and its components, such as blood cells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation. Such diseases might include hemophilia, blood clots, other bleeding disorders and blood cancers such as leukemia, multiple myeloma, and lymphoma. The laboratory work that goes into the study of blood is frequently performed by a medical technologist or medical laboratory scientist. Many hematologists work as hematologist-oncologists, also providing medical treatment for all types of cancer. The term is from the Greek αἷμα, haima meaning “blood,” and -λoγία meaning study.

Evaluation

A 27 year-old male with sickle cell disease (HbSC) on hydroxurea and with a history of 2-3 hospitalizations per year for vaso-occlusive pain crises manifested by arthralgias and back pain presents to the emergency department with 3 days of worsening joint pain affecting his entire body but predominantly his knees and lower back. He is familiar with this pain and attempted therapy at home with ibuprofen, then hydrocodone-acetaminophen, and finally hydromorphone without improvement and presented to the emergency department.

On review of systems, he denied chest pain, cough, or shortness of breath. He has some periumbilical abdominal pain but tolerated normal oral intake on the day of presentation without vomiting nor changes in bowel habits. He otherwise denied fevers, peripheral numbness/weakness, urinary or fecal incontinence or retention. He similarly denies trauma, weight loss, night sweats, or intravenous drug use.

Objectively, the patient’s vital signs were normal and he was well-appearing. Mucous membranes were moist and skin turgor was normal. There were no appreciable joint effusions, warmth, nor limitation to active/passive range of motion of any joints. His back had no midline tenderness to palpation or percussion, normal range of motion in all axes and extremity sensation and strength testing were normal. Abdominal and genitourinary examinations were normal. The patient had preserved perineal sensation to light touch and normal rectal tone – a core temperature was obtained which was also normal.

Peripheral access was established and a parenteral dose of hydromorphone equivalent to his home oral dose was administered (0.015mg/kg). Repeat dosing was required at 15 minutes due to persistent pain scale of 10. Diphenhydramine and acetaminophen were also administered, for potential opioid-sparing effects, recognizing the limited evidence to support these relatively benign adjuncts.

Laboratory studies were notable for anemia (though stable compared to baseline measures), appropriate reticulocyte count, no evidence of hemolysis and with normal electrolytes and renal function.

A thorough history and examination did not identify a critical precipitant for the patient’s symptoms which were presumed to be secondary to a vaso-occlusive pain crisis. On reassessment, the patient’s pain was improved and an oral dose of hydromorphone was administered with continued observation and serial reassessments for two hours thereafter. The patient’s hematologist was available for follow-up the subsequent morning and the patient was discharged home.

Algorithm for the Evaluation and Management of Sickle Cell Crises

Hematologic Emergencies ,Sickle Cell Crises

  • Triggers: infection, acidosis, dehydration, cold-exposure, hypoxia, pregnancy
  • Presentation: exclude alternative more serious pathology prior to ascribing pain to vaso-occlusive crisis

Effects by Organ System

SYSTEMSYMPTOM
CNSFocal or generalized neurological symptoms, stroke, seizure
PulmonaryAcute chest syndrome (fever, chest pain, cough, hypoxia, pulmonary infiltrates), pulmonary embolism
GIAbdominal pain, nausea/vomiting
RenalPapillary necrosis
GUPriapism, testicular/ovarian ischemia
MuskuloskeletalBone pain (back, proximal extremities), exclude osteomyelitis, avascular necrosis
IDInfection, functional asplenia (streptococcushaemophilus)
OBPreterm labor, placental abruptions, SAB
OphthalmologyAcute retinal ischemia, hyphema (with intra-ocular hypertension)
Hematology
  • Sequestration crisis: acute anemia, often post-viral
  • Hemolytic crisis: acute anemia, reticulocytosis, hyperbilirubinemia
  • Megaloblastic crisis: folate deficiency
  • Aplastic crisis: inadequate reticulocytosis

Evaluation

  • CBC with reticulocyte count
    •  Hemoglobin: suggests sequestration or hemolytic crisis
    •  Reticulocyte index: suggests aplastic or megaloblastic crisis
  • LDH/haptoglobin: evaluate for hemolysis
  • UA: evaluate for infection/infarction
  • CXR: evaluate for acute chest syndrome

Management

  • Rehydration (hypotonic fluids)
  • Analgesia
  • Supplemental oxygen if hypoxic
  • Exchange transfusion for priapism, neurologic symptoms, aplastic/sequestration/hemolytic crises

Transfusion Reactions

  • Epidemiology: overall 0.25%, 0.09% severe
  • Management: stop transfusion

70M with a history of dementia presenting with 3 days of fatigue. The patient was unable to provide detailed history, however family members reported worsening fatigue with the patient requiring assistance with ambulation for several days. The patient was referred from an outside clinic after point-of-care hemoglobin of 6.7. No reported history of anemia, and no history suggestive of obvious external bleeding.

Vital signs stable, tachycardia and tachypnea noted with minimal exertion but saturating well on ambient air and in no acute distress. Examination notable for conjunctival pallor without scleral icterus, systolic flow murmur, brown stool guaiac negative.

CBC with hemoglobin of 7.5 , MCV 80.3 , RDW 22.4 , no leukocytosis and normal platelets. Also noted was an alkaline phosphatase of 828 , normal total and direct bilirubin, and undetectable serum troponin. Chest x-ray showed a possible pleural-based mass.

The patient was transfused two units of PRBC’s and admitted for further evaluation. CT chest/abdomen/pelvis revealed sternal and rib-based pleural soft-tissue mass, prostate mass, pelvic and retroperitoneal lymphadenopathy as well as extensive bony metastatic disease consistent with primary prostate cancer with diffused metastasis. Serum PSA was 2,087 . Iron studies suggested anemia of chronic disease. Reticulocytes were not obtained but may have suggested inadequate production index given extensive bony metastases and possible associated myelosuppression. The patient was symptomatically improved after transfusion and discharged with outpatient follow-up for discussions regarding possible biopsy and treatment.

Algorithm for the Evaluation of Anemia 

Lymphadenopathy Applied: Lymphoma

27 year-old female with no medical history presenting with neck swelling. She describes one month of progressive enlargement of a left-sided neck mass, and in the past two weeks has noted a new right-sided neck mass. This has been associated with worsening dysphagia to solids, describing a sensation of food lodging in the mid-chest and requiring liquids for passage – she attributes her recent 10lb weight loss to this. She also reports a non-productive cough for the past two weeks and generalized fatigue. She otherwise denies fevers, night sweats, chest pain, shortness of breath, nausea/vomiting, or changes in bowel/urinary habits. She has no known sick contacts or TB exposure risk factors. She has no medical history, no prior surgeries, does not take any medications and denies tobacco, alcohol or drug use.

Physical Exam

VS:T38.4HR98RR14BP108/68O299% RA
Gen:Well-appearing young female, in no acute distress.
HEENT:PERRL, EOMI, MMM without lesions. There is a 2x3cm firm, non-tender, mobile left supraclavicular lymph node, as well as two 1x1cm firm, non-tender lymph nodes in the left and right anterior cervical chains.
CV:RRR, normal S1/S2, no murmurs. No JVD.
Lungs:Clear to auscultation bilaterally. There is a transition to bronchial breath sounds along the trachea inferior to the sternal angle with normal tracheal sounds superiorly.
Abd:Soft, non-tender without organomegaly.
Ext:Warm and well-perfused with normal peripheral pulses. No axillary or inguinal lymphadenopathy.
Neuro:Alert and oriented, responding appropriately to questions. PERRL, EOMI, facial sensation symmetric, facial muscles symmetric, hearing grossly normal, palate rises symmetrically, tongue movements normal without fasciculation, SCM/trapezius normal. Normal FTN, RAM. Gait intact. Peripheral sensation and motor grossly normal.

Imaging

CT Chest – Axial

Anterior mediastinal mass with a wide differential – likely represents lymphoma or germ cell tumor. Less likely thymic or thyroid origin.

CT Chest – Sagittal

Anterior mediastinal mass with a wide differential – likely represents lymphoma or germ cell tumor. Less likely thymic or thyroid origin.

Assessment/Plan

27F with no PMH presenting with progressive localized lymphadenopathy. Resultant dysphagia, cervical and supraclavicular distribution as well as abnormal tracheal sounds concerning for mediastinal involvement. The patient is currently stable without evidence of airway compromise. ACT of the chest was obtained to evaluate for thoracic malignancy, which showed a large anterior mediastinal mass concerning lymphoma or germ cell tumor. The location of the mass likely explains the patient’s dysphagia due to compression of the esophagus, as well as the abnormal pulmonary exam with compression potentially irritating the trachea and triggering her non-productive cough. The patienthe t was admitted for further workup.

Lymphadenopathy Applied – Lymphoma

This case applies the differential diagnosis of lymphadenopathy. The most abnormal finding on examination was non-tender, left supraclavicular lymphadenopathy. The duration of symptoms and lack of tenderness is concerning for malignancy, and the left supraclavicular location suggests a thoracic or intra-abdominal source.

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Avoid heavy lifting, sudden bending, and prolonged bed rest.

Safe pathway to proper treatment

Care roadmap for: Hematology/Myeloma/Oncology; Types, Evaluation, Treatment

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
