Primary tracheal tumors are rare with the majority being malignant. Benign lesions are less frequent with primary tracheal schwannomas accounting for less than 0.5% of tracheal tumors. They are more common in females and their clinical presentation is non-specific. Chronic cough, progressive respiratory distress and even asthma-like conditions prevail as presenting symptoms and signs. Laryngotr...

Inverted papilloma is the most common benign tumor of nose and paranasal sinuses arising from lateral nasal wall and middle meatus. Histologically these tumors are composed of epithelial nests that are inverted, exophytic and cylindrical. Here we describe a clinical case of nasal cylindrical cell papilloma, which was treated by endoscopic excision.

UNLABELLED Forehead lumps which are commonly excised for cosmetic reasons, are done through a traditional open excision technique. In the Asian population, open excision commonly results in a pigmented scar which tends not to fade with time and this can be a concern to some patients. The aims of this paper are to describe an endoscopically assisted technique of surgery, with emphasis on the sub...

We reviewed the pathology of 81 malignant colorectal polyps in 80 patients treated by endoscopic polypectomy and assessed the importance of carcinomatous invasion of veins in the stalk (submucosa). All the patients were followed up for at least five years. Venous invasion was present in 30 of the polyps (37%). The histological features of lymphatic invasion were considered too subjective to be ...

INTRODUCTION Carcinoid tumors (CTs) represent the most common type of neuroendocrine tumors (NETs). Digestive CTs in the gastroduodenal and colorectal tracts may be assessed using endoscopy and echoendoscopy or endoscopic ultrasonography (EUS) with the goal of attempting local resection with curative intent without having recourse to surgery. OBJECTIVE Endpoints in this study included:--Asses...

Isolated sphenoid sinus lesions are an uncommon entity and present with non-specific symptoms. In this case report, the patient presented with a history of headaches for a duration of one month without sinonasal symptoms. A computed tomography scan showed a soft tissue mass occupying the sphenoid sinus. An endoscopic biopsy revealed fungal infection. Endoscopic wide sphenoidotomy with excision ...

Anorectal melanoma is a rare neoplasm that accounts for less than 1-4% of anorectal malignant tumors. The main therapeutic modality for anorectal melanoma is surgical treatment, with abdominoperineal resection or wide local excision being the most common approaches. A 77-year-old male with a history of cerebral infarction and hypertension presented with anal bleeding. Here, we report a case of ...
