Burkitt's lymphoma is a highly aggressive small B-cell lymphoma. The treatment of choice is complex chemotherapy. As a rare tumor in the head and neck area, Burkitt's lymphoma usually involves cervical lymph nodes, and only fewer than 25% of cases involves extranodal regions. Involvement of the paranasal sinuses has been reported in only 14 cases in the past century. We describe here two patien...

Twenty-three cases of deep mycoses were histologically diagnosed in 6500 surgical biopsy specimens examined during a three year period (1985-1988) in the Department of Pathology, University of Calabar Teaching Hospital, Calabar, Nigeria. These included 12 cases of African histoplasmosis, four of mycetoma, four of actinomycetoma, two of paranasal aspergilloma, and one of zygomycosis due to Conid...

Oncogenic osteomalacia (OO) is an uncommon but treatable cause of osteomalacia related to tumor production of FGF23, usually caused by benign mesenchymal neoplasms. Paranasal sinus glomangiomas are a rare cause of OO, with only one previously reported case. Here we describe a second case (first reported in English) of paranasal sinus glomangioma-induced osteomalacia in a 42-year-old man. He pre...

OBJECTIVE To report clinical characteristics and treatment outcomes of actinomycosis of the paranasal sinus. STUDY DESIGN Retrospective review. SUBJECTS AND METHODS The medical records of six patients with actinomycosis of the paranasal sinus between 1998 and 2006 were analyzed. RESULTS There were no immunocompromised patients and all lesions were unilateral. Only one patient had a histor...

Cavernous sinus thrombosis not only presents with constitutional symptoms including fever, pain and swelling but also with specific findings such as proptosis, chemosis, periorbital swelling, and cranial nerve palsies. It is known to occur secondary to the spread of paranasal sinus infections in the nose, ethmoidal and sphenoidal sinuses. However, paranasal sinus infection of dental origin is r...

Purpose. To present a unique case of Non-Hodgkin's-Lymphoma- (NHL) associated compressive optic neuropathy. Method. An 89-year-old male presenting with acute unilateral visual loss and headache. Results. Patient was initially diagnosed with occult giant cell arteritis; however after visual acuity deteriorated despite normal inflammatory markers, an urgent MRI scan revealed an extensive paranasa...

Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive version of squamous cell carcinoma (SCC) that preferentially occurs in the upper aerodigestive tract. Since the first description by Wain SL et al., in 1986, only 21 cases with BSCC in the nasal cavity or in the paranasal cavity have been reported in the English literature. We present a case of BSCC arising in a paranasal sinus, a...

Endoscopic sinus surgery is a standard procedure in the treatment of various pathologies such as chronic sinusitis or some types of neoplasms. The transnasal approach to tumours of paranasal sinuses is favourable due to functional and aesthetic reasons. We report a rare case of a large primary ectopic meningioma of the paranasal sinuses in a 48-year-old woman referred to the Otolaryngology Clin...

Osteoma is the most common benign tumour of the nose and paranasal sinuses. However, involvement of the sphenoid sinus by osteoma is rare. Most of the time, patients with paranasal sinus osteoma are asymptomatic. However, symptoms may present, depending on the location and extension of the tumour. We report a case of a patient with sphenoethmoidal osteoma found incidentally on imaging, with evi...

Actinomycosis is a chronic suppurating granulomatous disorder specific to soft tissue. It is produced by Actinomyces Israelii, gram positive anaerobic bacteria that are very difficult to culture, and a commensal saprophyte of the oral cavity (tonsillar crypts, saliva and gingival dental sulci) and the gastro-intestinal tract; it becomes a pathogen in the face of erosions of the oropharyngeal mu...
