Botryomycosis is a bacterial skin infection that typically presents with crusted, purulent large bumps.^[1] Sulphur granules generally discharge via sinuses, which heal leaving thin skinned scars.^[1]

It is most frequently caused by Staphylococcus aureus, and less frequently by Pseudomonas aeruginosa, E. Coli, Proteus, and Streptococcus, Bacteroides.^[1] Risk factors include weak immune system, HIV, alcoholism, and Job syndrome.^[1]

Diagnosis is by culture of the discharge.^[1] Treatment involves antibiotics and surgical removal.^[1]

The condition is uncommon.^[1]

Epidemiology

History

The disease was originally discovered by Otto Bollinger (1843–1909) in 1870, and its name was coined by Sebastiano Rivolta (1832–1893) in 1884. The name refers to its grape-like granules (Gr. botryo = grapes) and the mistakenly implied fungal etiology (Gr. mykes = fungus).^[2] In 1919 the bacterial origin of the infection was discovered.

Other animals

Botryomycosis has been known to affect humans, horses, cattle, swine, dogs and cats.
