Whipple's Disease: A Challenging Diagnosis.

Whipple's disease (WD) is a chronic multisystemic infection caused by Tropheryma whipplei. It is a rare condition with a wide spectrum of clinical presentations, necessitating a high clinical suspicion to arrive at the diagnosis. We present the case of a 65-year-old woman who experienced chronic, intermittent, and migratory polyarthralgia, weight loss, anorexia, and pyrosis. She was admitted due to bilateral deep vein thrombosis (DVT). She exhibited lymphadenopathy without hepatosplenomegaly, and lymph node biopsy revealed reactive lymphadenitis with intrahistiocytic bacilli that reacted positively to periodic acid-Schiff staining. This led to the suspicion of WD, which was subsequently confirmed through small bowel biopsies. She initiated treatment with ceftriaxone and experienced rapid clinical improvement. WD poses a diagnostic challenge. The signs and symptoms are often nonspecific and can result in misdiagnosis as a rheumatic or neoplastic disease. The presentation with DVT, while unusual, has been reported as a manifestation of WD.

Eagle's Syndrome Presenting as Peripheral Facial Palsy.

Eagle's syndrome (ES) is the elongation of the ossified styloid process that causes symptoms such as foreign body sensation, neck pain, and odynophagia. A styloid process greater than 25 mm in length should be considered abnormal. Facial palsy is a condition that affects the facial nerve and results in weakness or total paralysis of the facial muscles that control expression. Here, we describe a rare presentation of ES presenting as facial palsy. We present the case of a 62-year-old female who was admitted to the emergency department with right peripheral facial palsy. A computed tomography (CT) scan of the neck confirmed the diagnosis. The patient underwent conservative management and physical therapy, which resulted in good evolution with an improvement of symptoms. She was referred to the otorhinolaryngologist for surgical evaluation.

Case Report: Pure Red Cell Aplasia due to Angioimmunoblastic T-Cell Lymphoma.

Pure red cell aplasia (PRCA) is a rare bone marrow failure characterized by a progressive normocytic anemia and reticulocytopenia without leukopenia and thrombocytopenia. It can be associated with various hematological disorders but exceedingly rarely with angioimmunoblastic T-cell lymphoma (AITL). We report the case of a 72-year-old woman with PRCA associated with AITL. The patient presented with severe anemia (hemoglobin 2.6 g/dL) and a low reticulocyte count 0.7%. Direct and indirect Coombs tests were positive. A CT scan of the chest, abdomen, and pelvis revealed multiple lymphadenopathies. A cervical lymph node biopsy was compatible with AITL. A bone marrow biopsy showed medullary involvement by AITL and a severe erythroid hypoplasia with a myeloid:erythroid ratio of 19.70. The patient was started on CHOP and after 6 cycles the PET scan confirmed complete remission.
