Fungus ball of maxillary sinus generally affects immunocompetent and nonatopic subjects. Although endoscopic removal is the current gold standard treatment, removal is at times difficult due to an accumulation of fungal elements in the anterior ad inferior recesses. Aim. To present our experience of maxillary fungus ball treated by the "gauze technique" that avoids these removal difficulties. M...

Mimicry has evolved in a wide range of organisms and encompasses diverse tactics for defence, foraging, pollination and social parasitism. Here, I report an extraordinary case of egg mimicry by a fungus, whereby the fungus gains competitor-free habitat in termite nests. Brown fungal balls, called 'termite balls', are frequently found in egg piles of Reticulitermes termites. Phylogenetic analysi...

Fungus balls are tangled mats of hyphae that are often found in the maxillary sinus. In approximately half of affected patients, radiologic evaluation will reveal areas of hyperdensity within soft-tissue masses. Histopathologic examination will reveal no invasion of the mucosa and no granulomatous reactions. Surgical removal is sufficient because fungus balls are not known to recur. We describe...
