Benign schwannomas of the nasal cavity are rare. When they do occur, their clinical presentation is variable, and some are fairly vascular. We report the case of a 17-year-old boy who presented with epistaxis associated with a unilateral nasal mass that extended into the nasopharynx. The tumor was removed via a transpalatal approach. In most such cases, a clinical diagnosis of angiofibroma is made. In this case, however, histopathologic examination identified the lesion as a schwannoma.

We describe the case of a 65-year-old woman who presented with left nasal obstruction. Clinical and radiographic examinations revealed the presence of a soft-tissue mass that had obliterated the left nasal cavity. The mass was completely excised via an endoscopic approach. Histopathologic examination identified the tumor as an ossifying fibrosarcoma. The patient recovered uneventfully and remained free of disease at the 2-year postoperative follow-up. To the best of our knowledge, no case of an ossifying fibrosarcoma of the nasal cavity has been previously reported in the English-language literature. We discuss the features of this case and the clinical presentation, diagnosis, and management of fibrosarcomas of the nasal cavity and paranasal sinuses.

ABSTRACT Sinus histiocytosis with massive lymphadenopathy (SHML) (also known as Rosai-Dorfman syndrome) is a rare, idiopathic, benign and self-limiting histiocytic proliferative disorder. It most commonly involves the cervical lymph nodes. The disease has a benign course and involvement of the nasal cavity as an extranodal site is exceptional. Here, we report a case of bilateral sinonasal mass with subsequent involvement of cervical lymph nodes in 22-year-old lady. Histological examination of the cervical lymph nodes and nasal mass biopsy demonstrated evidences of Rosai-Dorfman disease (RDD). The clinical presentation, histologic characteristics, radiographic findings and treatment of the disease are discussed. How to cite this article Vaid L, Jain N, Gogia V, Mishra K.

Dementia is a major public health concern that afflicts an estimated 24.3 million people worldwide. Great strides are being made in order to better diagnose, prevent, and treat these disorders. Dementia is associated with multiple complications, some of which can be life-threatening, such as dysphagia. There is great variability between dementias in terms of when dysphagia and other swallowing disorders occur. In order to prepare the reader for the other articles in this publication discussing swallowing issues in depth, the authors of this article will provide a brief overview of the prevalence, risk factors, pathogenesis, clinical presentation, diagnosis, current treatment options, and implications for eating for the common forms of neurodegenerative dementias.

Nerve Sheath

Malignant peripheral nerve sheath tumor (MPNST) is a rare tumor that can develop on the lining of nerves and within the network of nerve fibers in different organs, and it is commonly found in the head and neck, limbs, and trunk. These tumors can occur in patients of any age. They most commonly occur in adults aged 20 to 50 years; however, fewer cases of this tumor in children have been reported. To date, no neonatal case of MPNST in the nasal cavity has been reported. Here, we report the case of a 4-day-old female newborn who presented with a nasal mass that re-enlarged after surgery and was diagnosed as MPNST of the nasal cavity on the basis of pathological results. This is the first report of MPNST in the nasal cavity of a neonate. Differential diagnosis and treatment of nasal masses have been proposed in the related literature.

Extracranial meningiomas may be subdivided into primary and secondary types based on absence or presence of intracranial attachments respectively. Primary sinonasal tract meningiomas are rare with unknown etiopathology and non-specific clinical presentation. Of these PEMs only 11.5% are in the nasal cavity and nasal septum. To our knowledge less than 50 cases of PEM of nasal cavity have been reported in the literature. We report a case of a 22 years old male who presented with epistaxis and increasing nasal stuffiness for the last one year.

The accuracy of the acoustic reflections method for the evaluation of human nasal airway geometry is determined by the physical limitations of the technique and also by the in vivo deviations from the assumptions of the technique. The present study 1) examines the sound loss caused by nonrigidity of the nasal mucosa and viscous loss caused by complex geometry and its influence on the estimation of the acoustic area-distance function; 2) examines the optimal relation between sampling frequency and low-pass filtering, and 3) evaluates advantages of breathing He-O2 during the measurements on accuracy. Measurements made in eight plastic models, with cavities exactly identical to the “living” nasal cavities, revealed only minor effects of nonrigidity of the nasal mucosa. This was confirmed by an electrical analog model, based on laser vibrometry admittance measurements of the nasal mucosa, which indicated that the error in the acoustic measurements caused by wall motion is insignificant. The complex geometry of the nasal cavity per se (i.e., departure from circular) showed no significant effects on the measurements. Low-pass filtering of the signal is necessary to cut off cross modes arising in the nasal cavity. Computer simulations and measurements in models showed that the sampling frequency should be approximately four times the low-pass filtering frequency (i.e., twice the Nyquist frequency) to avoid influence on the result. No advantage was found for the the use of He-O2vs. air in the nasal cavity.

Oculodermal Melanocytosis

This report describes the clinical presentation, diagnosis, and histopathologic features of oculodermal melanocytosis in a young dog. A 3-year-old male neutered Labrador Retriever presented with conjunctival and scleral hyperpigmentation of the right eye, with concurrent ipsilateral cutaneous hyperpigmentation involving the right side of the face. Initial skin and conjunctival biopsies revealed an accumulation of histologically benign melanocytes within the dermis and conjunctival stroma, respectively. Enucleation was elected 19 months later by the referring veterinarian due to the progression of ocular pigmentation with concurrent marked corneal lipidosis and the suspicion of a scleral mass. On gross and histopathologic examination of the globe, there was marked panuveal melanocytosis with extension into the sclera, bulbar conjunctiva, and connective tissue surrounding the optic nerve, as well as sharply demarcated ipsilateral hyperpigmentation of the facial skin. The findings are characteristic of oculodermal melanocytosis (nevus of Ota), a dermal melanocytic hamartoma presenting as cutaneous facial hyperpigmentation that corresponds to the distribution of the ophthalmic and maxillary branches of the trigeminal nerve, often with ipsilateral ocular involvement.

AbstractLangerhans cell histiocytosis (LCH) is a rare disease of the monocyte-macrophage system, characterized by the aberrant proliferation of specific dendritic cells. The clinical presentation ranges from a single bone lesion to widespread multiorgan involvement. This disease is usually considered to be a disease of childhood; however, the diagnosis is frequently made in adulthood. The course of the disease is fairly unpredictable and varies from spontaneous resolution to progress into a debilitating form, which compromises the vital functions with occasional fatal consequences. Langerhans cell histiocytosis exhibits a predilection for the hypothalamic-pituitary-axis, with diabetes insipidus being the most common endocrine consequence related to the disease, which may be prior to diagnosis or develop at any time during the course of the disease. The diagnosis of LCH should be based on histologic and immunophenotypic examination of a lesional biopsy, although other testing may be done, depending on the symptoms. There is no established, widely agreed-upon treatment of LCH, in general. The treatment depends upon the individual patient and the extent and areas of involvement. The present article aims to describe the case of a 26-year-old male patient whose symptoms started with a headache and occipital bone lesion that progressed later with diabetes insipidus.
