Which microscopic feature is associated with Tinea versicolor in lactophenol cotton blue mounts?

• A. Branching hyphae, occasional arthrospores
• B. Short, stubby hyphal elements and grape-like clusters of spores
• C. Pseudohyphae & chlamydospores/blastospores
• D. Hyphae do not grow geometrically

Answer: (B)

This question hinges on recognizing Malassezia furfur morphology in lactophenol cotton blue mounts. In tinea versicolor, the organism appears as short, broad, hyphal elements together with grape‑like clusters of spores (arthroconidia), which together create the classic “spaghetti and meatballs” pattern seen under this stain. That combination—short, stubby hyphae plus grape‑like spore clusters—best matches the characteristic appearance of this pathogen on lactophenol cotton blue. Other patterns described, such as long branching hyphae or pseudohyphae with chlamydospores, align more with dermatophytes or Candida, respectively, and do not fit Malassezia in this context.
