INTRODUCTION: Ameloblastomas are rare head and neck tumors, and yet the most common odontogenic neoplasms. They account for 1% and 11% of all head and neck and odontogenic tumors respectively. Embryologically, they originate from remnants of odontogenic epithelium. Their aggressive, destructive nature, as well as their anticipated high rate of recurrence, even after en bloc resection, poses a surgical predicament. PRESENTATION: We present a case of a 56 year-old Asian female with a multi-recurrent invasive ameloblastoma...

Infantile hemangiomas are the most common vascular neoplasm that present in infancy, with more than half affecting the head and neck region. Periocularly, hemangiomas may be complicated by visual loss through induction of strabismal, deprivational, or anisometropic astigmatism. We report a case of a 5-year-old girl who presented with orbital hemangioma with potential risk of visual loss who had excellent response to propranolol.

Many abnormalities of the orbit present with neuro-ophthalmic findings, such as impaired ocular motility or alignment, and sensory changes, including optic neuropathy. Comprehensive coverage of all orbital diseases is beyond the scope of this article. This review focuses on diagnosis and management of the most common and the most vision- or life-threatening orbital conditions as well as more recently discovered entities and points of active controversy. These conditions include orbital trauma, vascular disease, inflammatory and infectious diseases, and neoplasms...

A 90-year-old woman presented with 1-year history of right-sided progressive proptosis, neovascular glaucoma, blindness, and worsening ocular pain. No funduscopic examination was possible because of a corneal opacity. Head CT scan without contrast demonstrated a heterogeneous 4.1 cm (anterior-posterior) by 1.7 cm (transverse) cylindrical mass arising in the right optic nerve and extending from the retrobulbar globe to the optic canal. She underwent palliative enucleation with subtotal resection of the orbital optic nerve and tumor...

We present a rare case of giant cell-rich solitary fibrous tumor (SFT) arising at the left external auditory canal in a 31-year-old woman. The tumor was well-circumscribed and composed of spindle-shaped cells with abundant collagenous bands. Scattered multinucleate giant cells were observed, some of which lined pseudovascular spaces. Although a focal mild-hypercellular area was observed, mitoses were rare and necrosis was absent. Interstitial mast cells were scattered, especially in the hypercellular area. Immunohistochemically, CD34, vimentin, and Bcl-2 presented diffuse positivity...

Leptomeningeal dissemination of low grade Schwann cell neoplasms is an exceptionally rare occurrence, and has not been well documented in the literature. We encountered two cases of leptomeningeal dissemination of low grade Schwann cell neoplasms. Patient 1 was a 63-year-old woman with NF1 and a progressive low grade MPNST developing from a diffuse/plexiform orbital neurofibroma that arose in childhood. The neoplasm demonstrated local and leptomeningeal dissemination intracranially leading to the patient's death...

Neuroblastoma is an extremely rare pediatric neoplasm whose prognosis becomes poor and poor as the age advances. It can be sporadic or nonfamilial in origin. It is primarily a tumor of abdominal origin from where it metastasis to lymph nodes, liver, intracranial and orbital sites, and central nervous system. There is no standard dental treatment protocol for the management of neuroblastoma due to its poor survival rate and rarity. However, dental treatment may follow the protocol of preventive and restorative...

Sinonasal neuroendocrine tumours (NETs) are rare, aggressive neoplasms with a high recurrence potential. There are no robust protocols for the management of these tumours. An 81-year-old man presented with an incidental sinonasal mass visualised on CT scan of head. Over the next few weeks he developed new onset, progressively worsening headache, right eye ptosis and restricted extraocular movements. Imaging confirmed a rapidly enlarging tumour involving the right nasal cavity and the orbit. Biopsy showed a large cell neuroendocrine carcinoma of the right ethmoidal sinus...

PURPOSE: Olfactory neuroblastoma (ONB) is a rare neuroectodermal malignant neoplasm that originates from the olfactory sensory epithelium. In reported cases involving the orbit, the primary neoplasms could invade the orbits through bone destruction or cranio-orbital communication anatomical structure. The present study reports a rare case of orbital metastatic tumor arising from an intracranial ONB in a Chinese patient, which is the first case demonstrating an uncommon route of ONB involving the orbit...

BACKGROUND: Inflammatory pseudotumour refers to a non-malignant tumour-like mass resulting from an inflammatory reaction that is composed of granulation tissue with leukocyte infiltration that commonly occurs in the paediatric or young adult population. These tumours occur more commonly in the lungs and the orbit but rarely does it affect the gastrointestinal tract. It poses a clinical diagnostic challenge since it is a benign condition than can mimic the malignant counterpart. Our case is a rare presentation of the caecal pseudotumour in the presence of a right undescended abdominal testis evaluated as a caecal tumour with a differential diagnosis of a testicular malignancy...

Rhabdomyosarcoma (RMS) is a fast growing, malignant tumour arising from immature mesenchymal cells, committed to skeletal muscle differentiation. It is more often seen in the paediatric population and constitutes less than 1% of all malignancies and less than 3% of all soft tissue tumours. RMS of the paranasal sinuses constitutes 10-15% of adult head and neck RMS, ethmoidal and maxillary sinuses being the most common. We report a 56-year-oldman presenting with left nasal obstruction, epistaxis on and off and left cheek swelling...

Schwannomas are benign nerve sheath tumors that may arise along the complex course of the cranial nerves (CNs), anywhere in the head and neck. Sound knowledge of the CN anatomy and imaging features of schwannomas is paramount for making the correct diagnosis. In this article, we review approaches to diagnosing CN schwannomas by describing their imaging characteristics and the associated clinical presentations. Relevant anatomic considerations are highlighted by using illustrative examples and key differential diagnoses categorized according to regions, which include the anterior skull base, orbit, cavernous sinus, basal cisterns, and neck...

Small cell neuroendocrine carcinoma (SNEC) is a rare form of malignancy. It mainly presents as bronchogenic neoplasm, and the extrapulmonary form accounts for only 0.1% to 0.4% of all cancers. These extrapulmonary tumors have been described most frequently in the urinary bladder, prostate, esophagus, stomach, colon and rectum, gall bladder, head and neck, cervix, and skin. Primary SNEC of the sinonasal tract is extremely rare with only less than 100 cases reported in the literature. Because of extreme rarity and aggressiveness of the tumor, the management for this entity varies considerably mandating multimodality approach...

Solitary fibrous tumor (SFT) is an uncommon neoplasm that usually arises from the pleura. Recently, SFTs have been reported in the head and neck region located in subsites such as the orbit. SFTs of the lacrimal sac are extremely rare, with only six cases reported in the English literature. We describe a SFT arising from the right lacrimal sac and extending along the nasolacrimal duct into the nasal cavity. Although, the tumor could not be removed by endoscopic-modified medial maxillectomy (EMMM) alone, combined approach with EMMM and a small external incision achieved the complete removal of the tumor...

INTRODUCTION: Epithelioid hemangioedothelioma (EHE) is a rare vascular tumor characterized by neoplastic proliferation of epithelioid or histiocytoid epithelial cells. EHE of bone constitutes <1% of primary malignant bone tumor. EHE in the skull is an extremely rare case. Here, we report a case of multiple neoplasm of the skull in a 15-month-old boy who presented with gradual facial swelling for 2 months. On computed tomography (CT) scan, multiple irregular osteolytic lesions were seen on the right maxillary, sphenoid, left zygoma, and roof of the left orbit...

Lymphomas of the ocular adnexa and intraocular tissue include a wide range of lymphoproliferative neoplastic disorders. They are predominantly extranodal non-Hodgkin lymphomas (NHL). The World Health Organization (WHO) classification of lymphoid neoplasm and individual morphological, immunophenotypical, and molecular genetic features, indicate that they may be divided into B-cell (approximately 80 % of all NHL) and T-cell lymphomas (approximately 10-20 % of all NHL). The most common forms of ocular NHL are extranodal marginal zone lymphoma (EMZL) of the mucosa-associated lymphoid tissue (MALT-type), follicular lymphoma (FL), diffuse large B-cell lymphoma, and mantel cell lymphoma...
