Overview

Natural History

Infection

  • The infection can be adquired in the first decade of life. PMC infection does not manifest symptoms. [1]

Acute/subacute

  • Acute PMC occurs in children and young adults. It constitutes only 3-5% of PMC disease. [2]
  • Symptoms take place weeks or months after the infection. [2]
  • The reticuloendothelial system organs and gastrointestinal tract are involved at this stage of the disease. [2]
  • Acute PMC starts with nonspecific symptoms such as fever, weight loss, weakness, anorexia, pallor, etc. Patients also find swollen lymph nodes in different body regions (cervical, axilar, paravertebral and retroperitoneal ganglia). Digestive, osteoarticular and cutaneous signs and symptoms are found. Pulmonary manifestations are rare. [3]

Chronic

  • Chronic paracoccidioidomycosis represents 90% of the disease manifestation.
  • The symptoms of chronic PMC usually develop in the third decade of life, even though the infection can be acquired in the first decade of life. [3]
  • The symptoms of paracoccidioidomycosis typically develop 20-30 years after exposure to Paracoccioides spp.
  • Symptoms develop slowly through the years.
  • Patients develop pulmonary symptoms (90%), with or without nonespecific symptoms. Nevertheless, other symptoms can occur such as cutaneous or mucosal lesions (51-82%). [4] [1]

Complications

Paracoccidioidomycosis develops sequelae frequently:

  • Chronic obstructive pulmonary disease (COPD)
  • Pulmonary fibrosis
  • Bullae
  • Pulmonary hypertension
  • Dyspnea
  • Adrenal gland insufficiency
  • Dysphonia
  • Laryngeal lesions (such as glottis estenosis)
  • Microstomia
  • Seizures
  • Motor deficiency [5] [6] [7]
