What tissue morphological feature identifies Sporothrix schenckii?

What tissue morphological feature identifies Sporothrix schenckii?

• A. Cigar-shaped budding yeast
• B. Broad-based budding yeast
• C. Spherules with endospores
• D. Pseudohyphae with arthroconidia

Answer: (A)

In tissue, Sporothrix schenckii is identified by its yeast form at body temperature, which appears as small, slender, cigar-shaped budding yeasts. This elongated, cigar-like appearance is distinctive under histology and helps differentiate it from other fungi that show different tissue morphologies, such as large spherules with endospores in Coccidioides, broad-based budding yeast in Blastomyces, or yeasts with pseudohyphae and arthroconidia in other species. Thus, the cigar-shaped budding yeast is the hallmark tissue feature for Sporothrix schenckii.
