The Varied Presentations of Sinonasal Region Schwannomas: Apropos of Four Cases.

Schwannomas of the sinonasal compartment are rare benign neoplasms of peripheral nerve sheath origin and constitute ~ 4% of all head and neck schwannomas. The presentation may simulate a range of benign and intermediate grade pathologies. Management involves surgical excision via open or endoscopic approach.

Recurrent respiratory epithelial adenomatoid hamartoma of the nasal cavity.

Respiratory epithelial adenomatoid hamartoma (REAH) refers to a rare entity characterized by excessive proliferation of the normal glandular elements of the respiratory epithelium present as mass lesions in various body sites.

Chasing the culprit in shadow - Sinonasal mucormycosis in an immunocompetent host.

Rhino-orbital mucormycosis is an uncommon, rapidly progressive, fulminant, angio-invasive deep mycosis usually affecting individuals with underlying immunosuppression, the most common being diabetes mellitus. In such, the course may be fatal with dissemination. Early detection with control of underlying predisposing conditions is critical with respect to the prognosis.

Clinical Profile of Patients with Head and Neck Amyloidosis: A Single-Institution Retrospective Chart Review.

 Isolated amyloidosis involving the head and neck is a rare entity. The pathophysiology of the localized disease appears to be distinct from that of the systemic counterpart. Systemic progression of the localized disease is unusual, and the prognosis of the localized form is excellent.

Medication Error- A Case Report of Misadventure with Methotrexate.

Methotrexate is an antimetabolite drug with antineoplastic and immunomodulatory properties, useful as an antineoplastic agent in various haematological and solid tumours. MTX toxicity can occur because of accidental ingestion/overdose by the patient or because of prescription error. The toxic effects manifest as severe mucositis or as organ damage (bone marrow depression, renal/hepatic injury).

Oral Cysticercosis: A Case Series and Review of Literature.

The cysticercus is the larval form of the pork tapeworm. Oral cavity involvement of cysticercosis is rare but frequently reported from developing countries. This report presents 3 cases of oral cysticercosis involving the tongue and buccal mucosa in isolation.

Assessment of olfactory status in allergic and non-allergic rhinitis patients.

A study undertaken to assess the olfactory acuity in allergic (group I) and non-allergic rhinitis (group II) patients in comparison with age and sex matched controls (group III). Patients presenting with atleast three of the five cardinal symptoms of rhinitis i.e.
