Lab test interpretation
Stool Microscopy: Object Identification Challenge
A clinical coprogram challenge: microscopy of a 30-year-old woman's stool revealed objects approximately 50 µm long. Try to identify them.
Oncohematology
Hepatosplenic T-Cell Lymphoma Mimicking Bone Marrow Metastasis
A clinical case of hepatosplenic T-cell lymphoma: atypical cell clusters in bone marrow aspirate, immunophenotyping, and diagnosis.
Parasitology
Parasitology Case: Identifying Ova in Pool Water
Oval eggs, approximately 50 µm in size, were found in pool water. Identify the finding in a microscopic preparation with Turdyev's preservative.
Clinical cases
Microbiology Case: Sputum Culture in Pneumonia
A clinical microbiology case: sputum from a patient with severe pneumonia was examined. Identify the pathogen based on growth on BCYE agar and colony microscopy.
