Case Reports
Primary olfactory neuroblastoma originating from the inferior meatus of the nasal cavity.
Olfactory neuroblastoma is a rare malignant tumor of the nasal cavity arising from the olfactory neuroepithelium. It usually presents as a polypoid mass high in the nasal vault including the cribriform plate, superior turbinate, and superior portion of nasal septum. An 89-year-old man visited our office with symptoms of occasional left nasal bleeding and obstruction. ⋯ Biopsy was performed, and the diagnosis of olfactory neuroblastoma was confirmed by histopathologic examination and immunohistochemical staining. The tumor was resected via medial maxillectomy, and the final pathologic report established that it was primary olfactory neuroblastoma that occurred from the inferior meatus. In this report, a literature review was performed on the pathologic characteristics and prognosis of the tumor, and possible hypotheses that olfactory neuroblastoma has originated from the inferior meatus were discussed.

Review Case Reports
Non-Hodgkin's lymphoma of the frontal sinus presenting as osteomyelitis.
The aim of the study was to present a case of non-Hodgkin's lymphoma (NHL) originating in the frontal sinus that presented as osteomyelitis of the frontal bone. ⋯ We describe a case of NHL of the frontal sinus, which presented as osteomyelitis. We highlight important features of this patient's clinical presentation that can help differentiate an inflammatory process from a neoplastic process in the frontal bone. Timely diagnosis is critical, and neoplasms of the frontal sinus can be easily misdiagnosed as inflammatory.

Foreign body ingestion is a common problem in children. An infrequent ingested item is an open safety pin (SP), which may become lodged in the esophagus and presents the endoscopist a challenge to his surgical judgment and technical skills. ⋯ The management of open SP ingestion is discussed, along with a review of the literature regarding this rare condition.

Mucormycosis is a fatal infection of the immunocompromised individuals. Apophysomyces elegans is an unusual pathogen causing mucormycosis. It is unusual to affect the healthy individuals. We report 5 such cases of infection caused by A elegans in immunocompetent individuals. ⋯ Mucormycosis must be considered in the differential diagnosis of any severe acute headache, sinusitis, or orbital cellulites not only in the immunocompromised patients but also in the absence of any underlying disease. Successful treatment requires early debridement and systemic antifungal treatment with injection of amphotericin B.
