Epidemiology and subtype distribution of lymphoid neoplasms from a single institution in Lebanon between 2010 and 2014

The 2008 WHO classification is the gold standard for classifying hematopoietic neoplasms. Our study reviewed 1256 cases between the years 2010 and 2014. It aimed to establish a descriptive status of lymphoma cases in Lebanon. Hodgkin lymphomas [HL] accounted for 21% of all cases whereas non-Hodgkin lymphomas [NHL] accounted for 79%. In NHL, mature B-cell neoplasms accounted for 85% and mature T-cell neoplasms accounted for 9%. For mature B-cell neoplasms, the majority of cases [48%] were diffuse large B-cell lymphomas [DLBCL]. Within T-cell lymphomas, anaplastic lymphoma [ALCL 40%] was the most prevalent. The distribution within subtypes confirmed the findings of two previous Lebanese studies. Our figures of HL are higher than in Eastern and Western countries. This could probably be related to EBV infection among other etiologies. Our NHL figures are close to the Western world. Westernization of the way of life of the Lebanese society could explain this result

Fibro-osseous and respiratory epithelial hamartoma of the fronto-ethmoid region

A 31-year-old lady presented to the otorhinolaryngology clinic complaining of right exophtalmus. Imaging studies revealed a right frontal sinus mass, suggestive of a mucocele, and fronto-ethmoidal ground glass opacification. In the operating room, the frontal sinuses were exposed through an osteoplastic flap, and connected to the nasal cavity through a Lothrop-like drainage pathway. The pathologic analysis revealed a frontal sinus mucocele and fibro-osseous and respiratory epithelial hamartoma of the fronto-ethmoid region. In this case report, this rare pathology is discussed, in addition to a thorough elaboration upon the surgical options as dictated by the anatomic complexity of the region
