Peripheral Smear (PS) examination still remains a cornerstone and first step towards diagnostic work up of patients. However, presence artefacts in PS can sometimes prove perplexing for the pathologists [1]. In one such experience, early morning blood sample K2 EDTA vial 23 year old female was sent to hematology lab.

We report a rare genetic disorder case of neuroacanthocytosis with clinical profile (oro-lingual-facial abnormal involuntary movements, neuropathy) and typical magnetic resonance findings (cerebral atrophy, bilateral caudate nuclei atrophy with dilated anterior horns of the lateral ventricles), positive family history in his brother and acanthocytosis in peripheral blood smear.

Microscopic examination of a peripheral blood smear revealed ookinetes of Plasmodium vivax. This unusual finding was probably due to an excessive delay between blood collection and smear preparation. Ookinete formation normally occurs in the mosquito gut. When seen in blood smears, it can cause confusion and misidentification of the parasite.

A 69-year-old man had lethargy and lower-back pain for several months. His physical findings showed mild congestive heart failure and no focal neurologic signs. The CBC was normal except for thrombocytopenia. Renal and hepatic function were normal. A sedimentation rate was markedly elevated, and his peripheral smear ( 40) is shown. The stacking of cells (rouleaux formation) facilitates the rate...

infection resulting from plasmodium vivax is the commonest type found in india as well as other tropical regions. the clini­cal picture is variable depending on the nature, immunity of the child, and lives in an endemic area or not. here, we report a child, who presented with cerebellar dysfunction with intact sensorium and plasmodium vivax was positive on peripheral smear.

Mean corpuscular hemoglobin concentration (MCHC), a parameter that is reported as a part of a standard complete blood count by automated analyzer, is a measure of the concentration of hemoglobin in a given volume of packed red blood cell. Values of MCHC significantly above reference range are not physiologically possible due to limitations on solubility of hemoglobin. The high MCHC can give us ...
