Skin lesion of Histoplasmosis

Symptoms:

• skin lesion
  • located on the mouth or lining of the cheek
  • papule, pustule, or plaque
  • usually erodes or ulcerates
  • reddened, may appear bruised
  • surface rough, wart-like
  • may be painful

• erythema nodosum

Signs and tests:

The diagnosis of skin lesion of Histoplasmosis is based on the appearance of the skin lesion, coupled with a history of travel or residence in an endemic area and environmental or occupational exposure to chickens, bats, blackbirds, pigeons or other birds, or their feathers or droppings.

A biopsy of the skin lesion may show the associated fungus.

Because the skin lesion is usually associated with systemic infection, including the lungs and other areas, tests for infection in these areas may be performed, including:

• abdominal MRI
• abdominal CT scan
• chest x-ray
• chest MRI
• chest CT
• ultrasound of the abdomen
