Abstract Collision tumours are defined as multiple neoplasms adjacent to each other or combined in one area and particularly rare, with only basal-squamous cell carcinoma combination of the head neck region published literature. Case description An 87-year-old farmer presented Maxillofacial Surgery department following referral by his general practitioner concerned suspected skin neoplasms. Fou...

Neuroendocrine tumours (NETs) of the head and neck are rare neoplasms and can be of epithelial or non-epithelial differentiation. Although the natural history of NETs is variable, it is crucial to establish an early diagnosis of these tumours as they can be potentially curable. Conventional anatomical imaging and functional imaging using radionuclide scintigraphy and positron emission tomograph...

OBJECTIVE To determine the pattern of occurrence of sarcomas afflicting the neck and craniofacial region. DESIGN A retrospective study (1982-1991). SETTING Cancer Registry, Kenyatta National Hospital, Nairobi, Kenya. METHOD Examination was performed of the cancer records in the registry over the period 1982 to 1991 inclusive. Histopathological types of the sarcomas were then analysed to i...

Lipoblastomas are benign neoplasms of white adipose which usually occupy the trunk and limbs in pediatric patients. They can seldomly involve head neck, as a lateral cervical mass. Magnetic resonance imaging is most useful modality for identifying these lesions. Treatment involves complete excision, patients followed with serial exams and/or recurrence more common neck. Here we present an excee...

Introduction: The presence of salivary heterotopic tissue is uncommon and even more rarely neoplasms arise from aberrant salivary gland tissue. The finding of a benign mixed tumour (pleomorphic adenoma) in heterotopic salivary tissue along the anterior border of the sternocleidomastoid muscle, in the upper neck, is extremely rare. Case Report: We present the fourth case in adults patientsof ect...

Introduction: Desmoid tumors are very rare, benign fibrous neoplasms arise from the musculoaponeurotic structures throughout the body.   Case Report: The patient was a   seven-year old boy with a large mandibular mass growing over a period of six months. His CT-scan showed a large mass, 13 cm in diameter in the cheek area extending to the neck and trachea. Biopsy was compatible with desmoid fib...

Schwannomas are peripheral nerve sheath benign tumors which arise from the schwann cells. These neoplasms most frequently seen in 3 to 6 decade of life and affecting limbs followed by head neck region. Oropharyngeal vallecular involvement schwannomas is extremely rarely reported previous literature. We report a case 25 year old male with lesion vallecula was subsequently diagnosed as on histopa...

  Background and Objective: Approximately 45% of benign peripheral nerve sheath tumors (PNST) occur in head and neck regions. Malignant peripheral nerve sheath tumors (MPNST) are less common and only 8-15% of these tumors occur in head and neck region. In this study, we aimed at evaluating the demographic characteristics, pathologic findings, locations, main clinical presentations and family h...
