A gardener has multiple vesicles on hand and multiple eruptions along the lymphatics. Most common fungus responsible is ?
**Core Concept**
The question is testing the student's knowledge of fungal infections, specifically the characteristics of cutaneous fungal infections and their spread through lymphatic channels. The student should be familiar with the typical presentations of different fungal infections and their modes of spread.
**Why the Correct Answer is Right**
The correct answer is **C. Sporothrix schenckii**. This fungus is responsible for sporotrichosis, a cutaneous infection that typically enters the body through a skin lesion and then spreads along the lymphatic channels, causing multiple eruptions and vesicles. The fungus is usually found in soil and plant material, and the infection is often acquired through gardening or other activities that involve contact with soil.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because **Histoplasma capsulatum** is a fungus that typically causes histoplasmosis, a respiratory infection that is often acquired through inhalation of spores. While it can cause skin lesions, it is not typically associated with lymphatic spread.
**Option B:** This option is incorrect because **Candida albicans** is a fungus that is commonly found on the skin and mucous membranes, but it is not typically associated with lymphatic spread or the formation of vesicles.
**Option D:** This option is incorrect because **Trichophyton rubrum** is a fungus that causes ringworm and other dermatophyte infections, but it is not typically associated with lymphatic spread or the formation of vesicles.
**Clinical Pearl / High-Yield Fact**
The "gardeners' disease" is a colloquial term for sporotrichosis, which is often acquired through gardening or other activities that involve contact with soil.
**Correct Answer:** C. Sporothrix schenckii
