Nerve Of Origin

Background. Schwannomas, also known as neurilemmomas, are benign peripheral nerve sheath tumors. They originate from any nerve covered with schwann cell sheath. Schwannomas constitute 25–45% of tumors of the head and neck. About 4% of head and neck schwannomas present as a sinonasal schwannoma. Brachial plexus schwannoma constitute only about 5% of schwannomas. Cervical vagal schwannomas constitute about 2–5% of neurogenic tumors. Methods. We present a case series of 5 patients of schwannomas, one arising from the maxillary branch of trigeminal nerve in the maxillary sinus, second arising from the brachial plexus, third arising from the cervical vagus, and two arising from cervical spinal nerves. Result. Complete extracapsular excision of the tumors was achieved by microneurosurgical technique with preservation of nerve of origin in all except one. Conclusion. Head and neck schwannoma though rare should be considered as a differential diagnosis of a unilateral slow growing mass in the head and neck region, particularly in an adult. Schwannomas are always a diagnostic dilemma as they are asymptomatic for long time, and histopathology is the gold standard for diagnosis. As a rule, treatment is surgical and dictated by the location of the tumor and nerve of origin. Due to its rarity, complex anatomical location and morbidity risk postexcision, they can pose a formidable challenge to surgeons. This study aims to describe the presentation, workup, surgical technique, and outcome.

Nerve Of Origin

Introduction. Schwannomas are tumors of neurogenic origin, that arise from Schwann cells which surround peripheral, cranial and autonomic nerves. Schwannomas account for only 5% of all benign soft tissue tumors, and 25-45% of extracranial schwannomas are present in the head and neck region. They are usually classified according to the nerve of origin and the site within the head and neck. Case report. We presented extremely rare extracranial localizations of schwannomas and discussed about diagnosis and management of these tumors. Conclusion. Schwannomas are slow-growing tumors and late symptoms appearance may cause a delay in diagnosis and treatment of patients with these tumors. An appropriate diagnostic protocol is indispensable tool in performing a differential diagnosis of malignant from benign lesions. Choice of surgical approach depends on schwannomas localization.

Unusual Lesion

Primary chondrosarcomas of the head and neck region are exceedingly rare neoplasms. These lesions have clinical and histologic characteristics that make them difficult to discern from benign chondromas. Additionally, they may arise from the periosteum, making it even more difficult to distinguish them from osteosarcomas. We present a patient with a periosteal chondrosarcoma of the maxilla. Characteristic radiologic and histologic findings associated with this lesion are described. This is the first reported case of such a lesion in the maxilla, as previous reports of periosteal chondrosarcomas have involved long bones. The diagnostic dilemma posed by this extremely unusual lesion is discussed, as well as treatment options.

Painless Mass

Leiomyosarcoma (LMS) is a malignant tumour of smooth muscle origin commonly seen in genital and gastrointestinal location. However, its presence in the head and neck region in a young child is extremely rare. Authors present a unique case of LMS in a one year and five-month-old child who presented with a painless mass in the right temporal region of the head. Histopathological examination revealed a highly cellular tumour arranged in intersecting fascicles of spindle cells with brisk mitotic activity and interspersed areas of necrosis. On Immunohistochemistry (IHC), the tumour cells were positive for Smooth Muscle Actin (SMA), Desmin and Vimentin and negative for S100 and Myogenin. A diagnosis of LMS was thus, made. Head and neck sarcoma is a broad entity encompassing plethora of differentials with closely overlapping morphological features which renders them diagnostically challenging, this can be resolved by employing various immunohistochemical stains readily available in all laboratories. This case highlights the combined role played by histopathology and immunohistochemistry in arriving at the correct diagnosis. To the best of our knowledge, this is the first case of LMS reported in the temporal region of head and is distinct with respect to its rare incidence, location and age at presentation. LMS at this site may masquerade as deceptively benign painless mass and may not be suspected initially, however one should bear in mind that these are moderate-to-high grade tumours and any delay in management may portend poor prognosis. Timely and aggressive surgical management is thus, the mainstay of treatment and critical to patient survival.

ABSTRACT Context: Extra-nasal rhinosporidiosis is not uncommon in endemic region like India. Clinical presentations of extra-nasal rhinosporidiosis lesion often lead to diagnostic dilemma. Cytology can help in the preoperative diagnosis of such lesions. Aims: The aims of our study were to find the clinico-pathological presentation of extra-nasal rhinosporidiosis and to evaluate the role of cytology in diagnosing these lesions preoperatively. Settings and Design: Fine-needle aspiration cytology is often used for preoperative diagnosis of sub-cutaneous lesions of the head and neck region. This retrospective study was designed to include the cytologically diagnosed cases of rhinosporidiosis and to compare with final histopathology of the lesions. Materials and Methods: A total of 21 cases of extra-nasal rhinosporidiosis were diagnosed in our study period of 18 months. Cytology was approached in 17 cases and 16 cases were diagnosed as rhinosporidiosis, which were included in the study group. Twelve cases were sampled by fine-needle aspiration and four cases by scrap technique. Histopathological confirmation was possible in all cytologically diagnosed cases. Results: Head and neck region were involved in 15 cases and only one case was on the skin of right upper arm. Orbital region was the most common extra-nasal site of involvement. Most of the cases (13 cases, 81.25%) belonged to the age group of 11-30 years. All cytologicaly diagnosed cases of rhinosporidiosis were concordant with histopathology. Only one false-negative case was cytologically diagnosed as suppurative inflammatory lesion. Sensitivity and specificity of cytology in diagnosis of extra-nasal rhinosporidiosis were 94.11% and 100% respectively. Conclusions: Extra-nasal rhinosporidiosis is an important differential diagnosis of nodular, polypoid mass of head-neck-face region. Cytology can be used as an important tool in preoperative diagnosis of extra-nasal rhinosporidiosis.
