Abstract

Lipoma is a slow growing, encapsulated, lobulated,
fluctuant and painless tumour composed of fat cells. It occurs anywhere in the
body where fat is found and hence the name ‘universal tumour’ or ‘ubiquitous
tumour’. We aimed to review and evaluate the
epidemiology of Subcutaneous Lipomas in this study. All 126 patients who had a
non-visceral lipoma diagnosed on histopathological examination during a period
of 1 year were analysed as regards the age, gender, size, site and multiplicity
of the lipomas. The lipomas were smaller than 5 cm in 75 of the 126 patients (71.90%). Multiple
subcutaneous lipomas were found in 22 patients (17.46%), most of them young males. 62.98 % (70 out of
126) patients were between the age group of 40 to 60 years.  The prevalence of subcutaneous, non- visceral
lipomas was more common in males as in our study, out of 126 patients, 78 (61.90%)
patients were males and 48 (38.09%) patients were females. As a result in this
study, lipomas were common, benign, slow growing, and generally asymptomatic
tumours. They were more common in males and commonly occurred in the age group
of 31- 60 years. They commonly occurred in the head and neck and trunk region
and were usually less than 5 cm in size.

Deri Altı Lipomların Epidemiyolojisi

Abstract

Lipom,
yağ hücrelerinden oluşan yavaş büyüyen, kapsüllenmiş, yuvarlak çıkıntılı,
dalgalanan ve ağrısız bir tümördür. Vücudun yağ bulunduğu yerde ortaya çıkar ve
adından da anlaşıldığı gibi “yaygın tümör” veya “her yerde bulunan tümör”dür. Bu
çalışmada Subkutan Lipomların epidemiyolojisini gözden geçirmeyi ve
değerlendirmeyi amaçladık. 1 yıl boyunca histopatolojik inceleme yapılmayan ve
visseral olmayan lipomlu 126 hastanın tümü yaş, cinsiyet, boyut, bölge ve
lipomun çokluğu açısından incelendi. 126 hastanın 75'inde (% 71,90) lipomlar 5
cm'den küçüktü. Çoğu genç erkek olan 22 hastada (% 17,46) multipl subkütan
lipom bulundu. 126 hastanın 70'i (%62,98) 40-60 yaş grubu arasındaydı.
Çalışmamızda deri altı, non-visseral lipomun prevalansı erkeklerde daha yaygındı,
126 hastadan 78'i (% 61,90) erkek, 48'i (% 38,09) kadındı. Bu çalışmada sonuç
olarak, lipomlar yaygın, benign, yavaş büyüyen, genellikle asemptomatik
tümörlerdi. Erkeklerde daha yaygın ve 31-60 yaş grubunda yaygın olarak ortaya
çıkmıştır. Genellikle baş, boyun ve gövde bölgesinde ortaya çıkmış ve
genellikle 5 cm'den küçüktü.
