Pure red cell aplasia following thymothymectomy: a case report

Area of Science:

• Oncology
• Hematology
• Pathology

Background:

• Thymoma is the most common anterior-superior mediastinal neoplasm.
• It can be associated with conditions like myasthenia gravis and pure red cell aplasia (PRCA).
• While only 5% of thymoma cases develop PRCA, 10-50% of PRCA patients have an associated thymoma, often spindle cell type, indicating a poor prognosis.

Purpose of the Study:

• To report a case of thymoma complicated by pure red cell aplasia (PRCA).
• To highlight the importance of ongoing vigilance in patients with thymoma, even post-thymectomy.

Main Methods:

• Case report of a 38-year-old female presenting with chest pain and an anterior mediastinal mass.
• Diagnosis of mixed thymoma confirmed via histopathology after thymectomy.
• Monitoring for associated conditions post-surgery.

Main Results:

• The patient was diagnosed with mixed thymoma.
• Two months after thymectomy, the patient developed pure red cell aplasia (PRCA).
• This case illustrates a known but infrequent complication of thymoma.

Conclusions:

• Thymoma complicated by PRCA has a poor prognosis.
• Clinicians must remain vigilant for PRCA in thymoma patients, irrespective of prior thymectomy.
• Early detection and management of PRCA in thymoma patients are critical.
