Allergic fungal sinusitis is the most common type of fungal sinus infection 1 2 3.People with this fungal infection characteristically develop polyps, or growths of tissue, within the nasal passageways, reports The Merck Manuals Online Medical Library 2.Nasal polyps typically form in one nostril and may cause chronic inflammation and nasal congestion. Since allergic fungal sinusitis was initially described by Millar in 1981, many have tried to define and explain the disorder. Mold spores are very light and are floating in the air. Minimally invasive surgery . Allergic fungal sinusitis was first described in 1983 as a benign fungal disease of the sinuses in immunocompetent patients. Immunoglobulin E-mediated hypersensitivity to fungal allergens was not evident in the majority of AFS patients. The identity of the isolate was confirmed by sequencing of ITS region of rDNA. Regional variation in incidence has been reported, with the southern and southwestern US particularly endemic. The patient was taken to the operating room and tissue for microscopic evaluation was obtained. J Assoc Physicians India. Image studies show complete opacification of the left frontal sinus, left sphenoid sinus, and the left maxillary sinus.

Allergic fungal sinusitis is relatively rare and is a particularly challenging type of sinus infection to treat and manage. It is unclear if eosinophilic mucin rhinosinusitis (EMRS) is a distinct entity from allergic fungal sinusitis (AFS) because: Fungal hyphae are not always detected in allergic mucin, although the sensitivity for fungal detection by the gold standard Gomori methanamine silver (GMS) stain is dramatically improved by trypsin predigestion, which speaks against EMRS as a distinct entity Consequently, the disease process described only 15 years ago must be suspected to be diagnosed. 2 AFS is known to be a type I hypersensitivity reaction. The majority sinuses show near complete opacification. Involvement of sphenoid sinus can result in proptosis and loss of vision. Clin Exp Allergy 2008; 38:260. Corey JP(1).

The authors report 16 cases of AFS from our institution, along with a review of cases from the literature. Author information: (1)University of Chicago, Pritzker School of Medicine, Illinois. AFS is actually not an infection, but really an overzealous local immune response in the nasal and sinus tissue to exposure to mold. This rare condition occurs when exposure to airborne particles such as mold spores causes the lungs to become inflamed. This results from an inflammatory reaction to fungus in the sinuses. Rosenfeld RM, Piccirillo JF, Chandrasekhar SS, et al. allergic fungal sinusitis A hypersensitivity reaction to fungal antigens which is seen in patients who are atopic or whose immune system is in overdrive; it is typically accompanied by asthma and nasal polyposis.

Allergic Fungal Sinusitis (AFS) is a very frustrating condition to treat as it is not like a typical bacterial sinus infection at all. Allergic fungal sinusitis, a form of nasal allergy to environmental fungal elements resulting in the formation of allergic mucin and nasal polyps, is a common cause of sinus headache, nasal congestion, nasal discharge and other chronic sinusitis symptoms that do not respond to treatment with antibiotics. Allergic fungal sinusitis is characterized by the presence of mucin, which is a combination of fungus and mucus that builds up in the sinus cavity and creates a blockage. Despite the advancement in medical and surgical strategies, recurrence in AFRS in general poses another challenging problem with reported incidence that eventually can reach more than 60%. 3 in the United States. Allergic Fungal Sinusitis. Other signs and symptoms may include fever, headaches, a poor sense of smell, sore throat, and a cough. To the best of our knowledge, this is the first report of allergic E. rostratum sinusitis from Kuwait and Arabian Peninsula. Conclusion . Allergic Fungal sinusitis (AFS) patients have no unique symptoms, which set them apart from other chronic sinusitis patients. It occurs in people with reduced immunity.The maxillary sinus is the most commonly involved. Allergic fungal sinusitis (AFS) is the most common form of fungal sinusitis and is common in warm, humid climates. BSACI guidelines for the management of rhinosinusitis and nasal polyposis. After an initial work-up and imaging … It accounts for approximately 6% to 8% of all chronic sinusitis requiring surgical intervention and has become a subject of increasing interest to otolaryngologists and related specialists. Allergic fungal sinusitis (AFS) has been clinicopathologically defined as a noninvasive form of fungal infection. For most of us inhaling mold spores is no big deal but to those that suffer from AFS symptoms can range from mild to severe. 1995 Feb. 43(2):98-100. . Allergic fungal sinusitis (AFS), a noninvasive form of fungal sinusitis, is rarely seen in immunocompetent patients. In a recent survey of practice patterns, sinusitis accounted for approximately 20% of office visits to specialists in allergy and immunology (AI). On unenhanced CT the sinuses are typically opacified by centrally (often serpentinous) hyperdense material with a peripheral rim of hypodense mucosa. It accounts for approximately 6% to 8% of all chronic sinusitis requiring surgical intervention and has become a subject of increasing interest to otolaryngologists and related specialists. Acute invasive fungal sinusitis is a medical emergency, and surgery to remove the infected tissue should be performed immediately once the diagnosis is made. Background . Allergic fungal sinusitis is a noninvasive disease first recognized approximately one decade ago. Background: Allergic fungal sinusitis is a noninvasive form of fungal sinusitis that has recently been delineated as a distinct clinicopathologic entity. We report AFS masquerading as posterior cavernous sinus syndrome. An unusual type of chronic sinusitis in children is caused by an allergic reaction to fungi, referred to as allergic fungal sinusitis (AFS). algorithms for medical management of chronic sinusitis and allergic fungal sinusitis a presented (2).

The disease was first described my Millar and Associates in 1981 as allergic aspergillus sinusitis (1). Etiologically, most reported cases have been attributed to pigmented dematiaceous fungi. Allergic fungal sinusitis (AFS) was recognized more than a decade ago, initially by Millar and Lamb1, 2 in Great Britain and subsequently by Katzenstein et al. Allergic fungal sinusitis in the pediatric population. AFS patients may present with unilateral or bilateral nasal polyps 3 and are diagnosed by the presence of distinctive histological findings. The entity was originally termed "allergic Aspergillus sinusitis" because of the similarity histopathologically to the entity of allergic bronchopulmonary aspergillosis (ABPA). Arch Otolaryngol Head Neck Surg 1996; 122:1381. Reference Katzenstein, Sale and Greenberger 6 It has been estimated that this disease accounts for 5–10 per cent of all patients with chronic rhinosinusitis.

In summary, AFS is a newly recognized form of sinusitis, appearing in otherwise healthy young adults with a history of chronic bacterial or polypoid rhinosinusitis refractory to conventional therapy. The fungal elements and allergic mucin in allergic fungal sinusitis always look hypointense on MRI scanning and can be mistaken for absence of disease. Fungal sinusitis is the inflammation of the lining mucosa of the paranasal sinuses due to fungal infection. Allergic fungal sinusitis was diagnosed in 94 (93%) of 101 consecutive surgical cases with CRS, based on histopathologic findings and culture results. Allergic fungal sinusitis (AFS) is a noninvasive form of highly recurrent chronic allergic hypertrophic rhinosinusitis that can be distinguished clinically, histopathologically and prognostically from the other forms of chronic fungal rhinosinusitis. 20. 2006;96(2):286-290. doi: 10.1016/S1081-1206(10)61237-9 McClay JE, Marple B, Kapadia L, et al.
