Symptoms
Clinical manifestations of Blastomycosis range from subclinical infection to fatal disseminated disease. Symptoms can be discussed under pulmonary and extra-pulmonary presentations.
Pulmunory Blastomycosis
Presents clinically as acute and chronic.[1]
Acute
- The symptoms mimic with acute bacterial pneumonia presentation
- Presents with fever, chills, productive cough, with or without hemoptysis.
- Often self limited
Chronic
- Symptoms last for more that 2 months.
- Presents with weight loss, fever, night sweats, cough with sputum, and chest pain.
- This presentation can be confused with pulmonary tuberculosis, malignancy of lung.
- ARDS can develop as a result of endobronchial spread of infection which is dreadful complication with high mortality rate.
Extra-Pulmonary blastomycosis
The most common extra pulmonary sites involved in blastomycosis are skin, bone, genitourinary and CNS.
Cutaneous blastomycosis
- Skin is involved in 40-80% of the cases.[2]
- The cutaneous manifestations of blastomycosis comes in two forms verrucous and ulcerative.[3]
- Cutaneous blastomycosis is often confused with basal cell or squamous cell carcinomas or pyoderma gangrenosum.
Verrucous | Ulcerative | |
---|---|---|
Location | Above the subcutaneous abscess | Drainout from subcutaneous abscess through skin |
Morphology | Irregularly shaped lesions with raised and crusted borders | Heaped up borders with or without exudative base |

Oseous blastomycosis
- About 25% of the blastomycosis involve bone.
- Osteomyelitis is the most common presentation of oseous blastomycosis.[4]
- Most commonly involved bones include Vertebrae, ribs, skull and long bones.[5]
- Infection cans spread from the involved bone to surrounding joints (purulent arthritis) or soft tissue (subcutaneous abscess with draining sinus wichh can lead to the formation of an ulcer)[5]
- The most common complication of vertebral osteomyelitis is extension of infection from the spine, resulting paravertebral or psoas abscess.
Genito-urinary
- About 10 % of the blastomycosis involves genitourinary system.
- In Men the most commonly involved organs include prostrate, testicles and epididymis.
- Epididymo-orchitis causes swelling and pain, and prostatitis is associated with dysuria and symptoms of obstruction.
- Involvement of female genitourinary system is rare but if involved it causes endometrial infection or tubo-ovarian abscess.
Central nervous system
- About 5-10 % of blastomycosis involve CNS.
- It presents as meningitis or mass lesion.[6]
- CSF analysis of WBC reveals neturophilic predominance.[7]
- Laryngeal involvement causes hoarseness.
Other sites of disease
Blastomycosis can disseminate almost to any other site such as liver, spleen, breast, lymph nodes etc.[8]
