Ship’s wheel appearance
Ship’s wheel appearance:
Paracoccidioidomycosis. This silver stain highlights the ship’s wheel appearance of yeast forms budding off of the central parent yeast. The resemblance of the broad-based budding pattern to that of Blastomyces species is the reason for its alternative term, South American Blastomycosis. Paracoccidioidomycosis, also known as South American blastomycosis, is caused by the dimorphic fungus
Paracoccidioides brasiliensis and is the most common systemic mycosis in Latin America. It frequently involves the lungs and mucocutaneous areas of healthy individuals, and clinically simulates tuberculosis. There may be a hyperplasia of the bronchial epithelium overlying granulomas, which may lead to the erroneous diagnosis of SQC in cytologic material. There is a high sensitivity (50% to 90%) for the detection of the organism in cell block preparations of sputum.(Ref:Cytology, Cibas & Ducatman)
