IgG4-related inflammatory orbital pseudotumors - a retrospective case series.

Orbital diseases may be divided into congenital defects of the orbit, infectious and inflammatory diseases, orbital tumors (including malignant and benign tumors) and injuries. Idiopathic inflammatory syndromes are often encountered within the orbit and are usually classified as orbital pseudotumors. The etiology of pseudotumors of the vision organ is unknown.

Immunoglobulin G4-related disease (IgG4-RD) in the orbit: mucosa-associated lymphoid tissue (MALT)-type lymphomas.

Background: MALT lymphomas were classified for differential diagnostics of IgG4-dependent disease due to their exceptional predilection to intraorbital localization. Therefore, the goal of our studies was large retrospective analysis of patients diagnosed with MALT lymphomas within the orbital tissues, since no such studies have been conducted in Poland.

Material/methods: The starting study population consisted of 167 patients with isolated infiltrative tumor diseases within the orbital region treated at the Department of Otolaryngology, Head and Neck Surgery of the Medical College Jagiellonian University in Cracow.

The main aim of the study was to establish the frequency of orbital tumor occurrence in the patients of the University Hospital Otolaryngology Clinic in Kraków as well as to analyze the clinical features, location in the orbit and to identify the group of patients with the highest risk of orbital tumor. The authors retrospectively analyzed 46 patients (29 women and 17 men) between the ages of 23 and 87. This group of patients was compared to a group of 80 patients who were surgically treated at the same clinic 10 years ago and to a group of 70 patients treated 15 years ago.

[Extensive neck trauma in material of Otolaryngology Department of the Jagiellonian University in Krakow 2009-2012].

Isolated laryngeal fractures quite rarely can occur following trauma to the neck region, but because of the variety and dynamic growth of symptoms or possible injury of the main structures on the neck may be life-threatening. The appropriate treatment of these patients is quick surgical intervention proceeded by imaging techniques. Here we report the cases of three patients treated in our Department between 2009 and 2012: two of them with penetrating injury and one with blunt trauma.
