A gardener has multiple vesicles on hand and multiple eruption s along the lymphatics. Most common fungus responsible is?
A. Sporothrix shenkiiB. Cladosporium
C. Histoplasma
D. Candida
Ans.
A. Sporothrix schenckii
• Sporotrachosis is caused by the fungus Sporothrix (Sporotrichum) schenckii and is characterized by the development of nodules on the skin and lymph nodes which soften and break down to form indolent ulcers.
• The fungus is a saprophyte found widely on plants thorns and timber
• Infection is acquired through thorn pricks or other minor iniuries.
• The fungus spreads from the primary site through lymphatics but seldom extends beyond the regional lymph nodes.
• Most cases occur in the upper limb. In infected tissues the fungus is seen as cigar shaped yeast cells without mycelia.
• Sometimes asteroid bodies are seen in the lesion composed of a central fungus cell with eosinophilic material mediating from it.
• Diagnosis is made by culture as frequently the fungus may not be demonstrable in pus or tissues.
