[Midfacial necrosis secondary to cocaine-abuse].

Midfacial necrosis due to the abuse of inhaled cocaine is a new entity that is included in the differential diagnosis of the midline destructive diseases such as Wegener's granulomatosis, polymorphic reticulosis, nasal lymphoma, infections and the idiopathic midline destructive disease. We report the case of a forty-year-old male who presented necrosis of the nasosinusal tract and optic neuropathy as complications due to the abuse of inhaled cocaine for more than twenty years and a discussion about the differential diagnosis.

[Presentation of multiple oncocytic type laryngeal cysts. Clinical and histopathological findings].

Oncocytic cysts are a histologically well-defined subgroup of cystic lesions of the larynx. Oncocytic cysts of the larynx are rare, clinically similar to simple laryngeal cysts, and occur as a casual finding of pathology studies. Multiple oncocytic cysts have rarely been described. Microscopic examination of laryngeal biopsies showed cysts within the lamina propria lined by oncocytic epithelium. The differential diagnosis and pathogenesis of oncocytic cysts is discussed and other laryngeal cystic lesions are reviewed.

[Allergic fungal sinusitis].

Allergic fungal sinusitis is a recently described clinical entity that has gained increased attention as a cause of chronic sinusitis. Consist in a benign noninvasive sinus disease related to a hypersensitivity reaction to fungal antigens. It should be suspected in any atopic patient with refractory nasal polyps. Computed tomography (CT) findings are characteristics, but not diagnostic. Diagnosis requires show allergic mucin in the histopathologic examination and hiphae in special fungal stains. The suitable treatment includes the allergic mucin removal and sinus aeration accomplished endoscopically, perioperative systemic steroids and immunotherapy with fungal antigens. We present a case of this kind of chronic sinusitis describing the characteristic histopathologic and radiologic findings, the pathogenic theories and recent advances in immunotherapy.
