BACKGROUND Although already established for treatment for early-stage laryngeal cancers, transoral laser microsurgery indications for more advanced tumors are not unanimous. Additionally, no outcomes concerning the Portuguese population are currently accessible. METHODS Outcomes of 248 patients presenting laryngeal carcinoma primarily treated by transoral laser microsurgery with curative inte...

BACKGROUND Patients with small (<3 cm) intracranial meningiomas can be either observed or treated. Treatment can be either radiosurgery or microsurgery if and when tumor progression occurs. We compared local tumor growth control and recurrence-free survival (RFS) of microsurgical resection and radiosurgery in small intracranial meningiomas and identified predictors of unfavorable outcome. MET...

Anorectal malignant melanoma (AMM) is an uncommon malignancy that is thought to arise from melanocytes in the mucosa around the anorectal junction. AMM is commonly misdiagnosed, and definitive preoperative diagnosis is often difficult. The prognosis of AMM is relatively poor. Although radical resection is required for AMM, there is still no consensus at this moment on which surgical approach is...

Localized amyloidosis is characterized by amyloid protein deposition restricted to one organ or tissue without systemic involvement. Gastrointestinal manifestations of localized amyloidoma are unusual, which makes amyloidoma restricted to the rectum a very rare diagnosis requiring a high index of suspicion. We present a rare account for rectal amyloidoma with an unusual presentation of obstruct...
