The Mystery of the Ailing Student: A Pathology Case Study

Case Background:

A 20-year-old female student was admitted to the hospital with complaints of generalized weakness, fatigue, and episodes of fainting. She reported feeling unwell for the past few weeks and had lost significant weight despite a healthy appetite. The patient denied any significant medical history or regular medication use. On examination, the patient appeared pale with no obvious signs of distress. Vital signs were stable, and all systemic examinations were unremarkable. Routine laboratory investigations revealed severe hypochromic microcytic anemia, with a hemoglobin level of 6.5 gm/dl (normal range: 12-14 gm/dl). The patient was started on blood transfusions and referred to the pathology department for further evaluation.

Pathological Findings:

A bone marrow biopsy was performed, which revealed an abnormal increase in the number of megakaryocytes, along with evidence of reticulin fibrosis. These findings were consistent with a diagnosis of essential thrombocythemia (ET). ET is a myeloproliferative disorder characterized by the overproduction of platelets by the bone marrow. It is a rare condition, with an annual incidence of approximately 1 to 2 per 100,000 individuals. The disease commonly affects middle-aged women and is associated with an increased risk of thrombotic complications.

Treatment and Outcome:

The patient was started on hydroxyurea, an anti-proliferative agent commonly used in the treatment of myeloproliferative neoplasms. Her anemia and platelet counts gradually normalized, and she was discharged with instructions for regular follow-up. The patient continued to comply with her medication regimen and follow-up schedule and has been disease-free for the past 3 years. In conclusion, essential thrombocythemia can present with non-specific symptoms and may often go undiagnosed. Early detection and timely intervention are crucial in preventing thrombotic events and improving patient outcomes. Accurate diagnosis requires a comprehensive evaluation, including clinical exam, laboratory investigations, and histopathological examination. Pathologists play a vital role in the diagnosis and management of myeloproliferative neoplasms, including ET.
