Rhinitis caseosa, nasal cholesteatoma and allergic fungal sinusitis.
ABSTRACT The recently described Syndrome of Allergic Fungal Sinusitis (AFS) has many similarities with the previously described entity of rhinitis Caseosa (synonym-Nasal Cholesteatoma). 28 patients treated over a 6 year period with a diagnosis of rhinitis caseosa/nasal cholesieatoma have been retrospectively reviewed with regard to their clinical and radiological features, operative findings and microbiologic and histopathologual features.All cases presented with nasal obstruction and nasal polyposis. CT scanning indicated intracranil extension and intra-orbital extension m 9 cases each. Surgical debridetnent with establishment of sinus drainage led to the universal initial relief of symptoms in all cases. 26 of 28 cases have remained free of recurrence on prolonged follow-up (minimum follow-up one year).Despite these cases demonstrating clinical, radiologital, morphological and histological similarities with the Syndrome of Allergic Fungal Sinustitis, in only 2 cases was a fungal aetiology confirmed by history. The clinical syndrome of "Rhinitis Caseosa" is described and its relationship with the Allergic Fungal Sinusitis (AFS) syndrome and the "AFS-hke" Syndrome explored.

ABSTRACT: Allergic fungal sinusitis (AFS) is a noninvasive disease first described as a distinctive clinical and histopathologic entity more than 10 years ago. The typical patient is immunocompetent, atopic, has chronic sinusitis refractory to medical therapy, and 100% of those we have diagnosed have nasal polyps. Because of the histopathologic similarity to mucoid impaction of the bronchi seen in allergic bronchopulmonary aspergillosis, Aspergillus species were initially suspected as the causative agent. Subsequent reports include a number of non-Aspergillus-related cases. Both we and others have found a 7% incidence of AFS among chronic sinusitis patients requiring surgery. Relapse after surgical debridement and aeration is common and often responds to systemic corticosteroids. The diagnosis of AFS should be considered in all atopic patients with nasal polyps and chronic sinusitis. The clinical and histopathologic features of this disorder are reviewed.Allergy proceedings: the official journal of regional and state allergy societies 01/1990; 13(1):3-6.

ABSTRACT: Despite documentation of specific immunologic hypersensitivity in a few case reports, controversy continues as to the role of allergy versus true infection in the clinical entity of allergic fungal sinusitis (AFS). Using a modified radioallergosorbent test (RAST) to multiple fungal antigens, 16 patients meeting the histologic criteria of AFS and with positive fungal cultures were compared to 5 control patients with similar preoperative clinical findings but without histologic or culture evidence of AFS. All patients were immunocompetent and none demonstrated histologic evidence of tissue invasion. All AFS patients were RAST-positive to at least one fungal antigen in the family of their cultured organism with positive defined as class 2 or greater. No control patient was RAST-positive to either dematiaceous or Aspergillus fungal antigens. Thus, modified RAST testing can aid in the routine clinical diagnosis of AFS, and it provides further serologic evidence for a type I hypersensitivity in the pathogenesis of AFS.The Laryngoscope 08/1993; 103(7):717-21.
