Which fungal infection is classically acquired by traumatic inoculation?
Show Hint
Think rose-gardener's disease, a thorn prick seeds the skin and the nodules climb the lymphatics.

- Sporothrix schenckii
- Blastomyces (blastomycosis)
- Coccidioides
- Paracoccidioides
Show Solution
The Correct Option is A
Solution and Explanation
Route-of-entry approach. Group the dimorphic fungi by how they get in. Three of these, Blastomyces, Coccidioides and Paracoccidioides, are inhaled: their conidia are breathed in from soil or dust and the infection begins in the lung. Only one is a cutaneous, trauma-seeded fungus, and that is Sporothrix schenckii. The clinical tag to memorise is rose-gardener's disease: a gardener pricks a finger on a thorn or sphagnum moss, the fungus is driven under the skin, and over weeks a chain of subcutaneous nodules and ulcers ascends the draining lymphatics (lymphocutaneous spread). So when the stem says traumatic inoculation, skip the three respiratory mycoses and pick the lymphocutaneous one. Answer: Sporothrix schenckii.
