The Secondary Manifestation of a Marginal Zone Lymphoma in the Larynx: Lessons From a Misdiagnosis.

The secondary manifestation of a marginal zone lymphoma (MZL), which is a less common type of B-cell non-Hodgkin's Lymphoma (NHL), in the larynx is a rarity. We report a case of the secondary involvement of the larynx following MZL in a 72-year-old woman who presented with the sensation of a foreign body in the throat and history of MZL. A fiberoptic laryngoscopy confirmed the presence of a mass in the supraglottic area.

Leiomyosarcoma of the Nasal Cavity.

Leiomyosarcoma (LMS) in the sinonasal tract (SNT) is a rarity that has been firstly described in 1958. Since then, there have been only a few articles about this entity. Most of the data available about LMS in the SNT is derived from case reports.

Cervical cancer screening in rural Ethiopia: a cross- sectional knowledge, attitude and practice study.

Background: Cervical cancer is the fourth most common cancer among women worldwide. Sub- Saharan Africa has a high incidence, prevalence and mortality due to shortage and underutilization of screening facilities.

Heterogeneity of Head and Neck Squamous Cell Carcinoma Stem Cells.

Current systemic cancer treatment in head and neck squamous cell carcinoma (HNSCC) is moving toward more personalized approaches such as de-escalation protocols human-papilloma-virus dependent HNSCC or application of checkpoint inhibitors. However, these treatments have been challenged by cancer stem cells (CSC), a small population within the bulk tumor, which are leading to treatment failure, tumor recurrence, or metastases. This review will give an overview of the characteristics of HNSCC-CSC.
