INTRODUCTION:Tuberculosis (TB) is still one of the most prevalent infections, especially in the developing world. The World Health Organisation (WHO) estimates that there are 8 million new cases annually [1,2]. Cough, sputum with or without haemoptysis, fever, and constitutional symptoms are the hallmark manifestations of an active tuberculosis infection. In patients with pulmonary TB, an increase in haemoglobin levels is regarded as an indicator of a positive response to treatment. Furthermore, Omar et al. found that a fall in platelet count, white blood cell (WBC) count, and erythrocyte sedimentation rate (ESR) were strong indications of clinical response [3]. Despite the possibility of an increase in white blood cells (WBC), which results in lymphocyte predominance, in clinical practice, eosinophilia is a usual finding that is self-limiting in moderate cases, but it is exceedingly infrequent in TB [4,5].Many allergic, viral, and neoplastic conditions may produce peripheral blood eosinophilia, necessitating a variety of examinations and subsequent therapy. Common causes of eosinophilia in children include infections with helminthic parasites, allergic diseases, malignancies, and adverse drug reactions [1,6]. One of the primary goals of the early evaluation is to identify an underlying cause that needs specific therapy. Even though difficulties linked with eosinophilia are more prevalent in individuals with higher eosinophil counts (>1500 eosinophils/uL), the peripheral blood eosinophil count does not accurately assess the risk of organ damage in each patient. A patient with modest peripheral blood eosinophilia may also have significant eosinophil organ involvement. Normal eosinophil counts in the human blood range between 0-350/mm3. This quantity accounts for between 1 and 3% of the differential leukocyte count [7]. Most reports of eosinophilia in tuberculosis describe local eosinophilia as opposed to peripheral eosinophilia [8]. To the best of our knowledge, reported cases are very rare. As a consequence, we describe one case of TB with considerable peripheral eosinophilia and the treatment outcome.
