Insights
Erdheim-Chester disease (ECD), a rare histiocytosis, presents varied symptoms. This case highlights successful treatment of aggressive systemic ECD with cladribine, offering hope for patients with this challenging condition.
Area of Science:
- Oncology
- Pathology
- Neurology
Background:
- Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis with poorly understood pathophysiology.
- Clinical manifestations of ECD are diverse, and diagnosis relies on pathological examination.
- The 'hair kidney' sign on CT scans is a characteristic diagnostic indicator.
Abstract:
Erdheim-Chester disease (ECD) is a form of non-langerhans histiocytosis mainly affecting men, whose pathophysiology is poorly understood. Clinical picture is heterogeneous. The presence of hair kidney sign on Ct scan is pathognomonic. Diagnosis is based on anatomopathological examination. We here report the case of a 50-year old patient presenting with disorders of equilibrium and slow speech as well as general health deterioration Clinical examination showed cerebellar ataxia. Radiological and pathological investigations showed aggressive systemic ECD. cladribine-based treatment was initiated with satisfactory outcome. ECD is an extremely rare disease. Systemic forms are generally associated with poor prognosis and are refractory to treatment, unlike in the case of our patient who was treated with cladribine with good outcome.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
