==Overview==
Blastomycosis have overlapping signs & symptoms with that of other fungal and bacterial disorders. A detailed History, Physical examination and serological tests helps us to pin-point the diagnosis. All this disorders can be often misinterpreted as community acquired pneumonia as they all present with similar complaints such as fever, productive cough, chest pain and shortness of breath. The following table elaborates differentiating features between blastomycosis  from other fungal disorders.

==Chronic and disseminated disease==
Chronic blastomycosis may be initially confused with a malignancy or tuberculosis. While spread to other areas may be confused with malignancy as well. Skin lesions are often misdiagnosed as pyoderma gangreosum or keratoacanthoma. Therefore, a high index of suspicion is needed on the part of physician to diagnose blastomycosis

Overview

Blastomycosis has overlapping signs & symptoms with that of other fungal and bacterial disorders. A detailed history, physical examination, and serological tests help us to pinpoint the diagnosis. All these disorders can be often misinterpreted as community acquired pneumonia as they all present with similar complaints such as fever, productive cough, chest pain and shortness of breath.

Fungal

The following table elaborates differentiating features between Blastomycosis from other fungal disorders:

Pathogen Disease Geographic distribution High risk Groups Differentiating features Microscopic findings
Physical exam Laboratory findings
Fungal Histoplasmosis Mississippi and Ohio River valleys
  • Cave dwellers
  • Soil that contains bird or bat dropping[1]
Yeast are typically smaller, with narrow-based budding, found intracellularly within macrophages
Coccidioidomycosis Southwestern US region Opportunistic infection seen in AIDS Serologic tests (enzyme immune assay) more sensitive Characteristic spherule appearance
Paracoccidioidomycosis[3] Central and South america Opportunistic infection seen in AIDS Smaller fungi with thin cell walls, forming mariner wheel appearance, circumferentially surrounding the parent cell. (Captain wheel appearance)
Sporotrichosis Ubiquitous Gardeners [4] + Sporotrichin skin test Finger or cigar shaped yeast.
Aspergillosis[5] Ubiquitous Cell wall detection using galactomannan antigen detection, Beta-D-glucan detection test. Septated hyphae with acute angle branching
Bacterial Anthrax Ubiquitous Live stock handlers Nonmotile, Gram-positive, aerobic or facultatively anaerobic, endospore-forming, rod-shaped bacterium
Legionella Ubiquitous Chronic lung disease
