A Histopathological Pattern of vascular tumours in North Eastern Nigeria
Abstract
Aims: To review the histopathological pattern, age, sex, site and behaviour of the vascular tumours in North Eastern, Nigeria.
Methods: This is a retrospective study of vascular tumours diagnosed between January 1992 and December 2001 in the Histopathology Department of University of Maiduguri Teaching Hospital.
Results: A total of 139 cases of vascular tumours were histologically diagnosed. The age ranged between 2 months and 60 years with 105 (75.5%) adults and 34 (24.5%) children. The mean age for adults was 31.2 years and children were 7.3 years. There were 88 (63.3%) males and 51 (36.7%) females giving a male, female ratio of 1.7:1. Benign and malignant vascular tumours accounted for 58% and 42% respectively. The commonest tumour was hemangioma, which accounted for 50.3% of all tumours. Kaposi sarcoma is the predominant malignant lesion accounting for 55(39.6%); Lymphangioma 11(8.0%); Glomus tumour 2(1.4%) and Haemangioendothelioma 1(0.7%). The commonest site of all vascular tumours is the head and neck (30.9%). The leg and foot is the commonest site of Kaposi sarcoma (43.7%). Out of the 55 cases of kaposi sarcoma, 34 of the patients were screened for HIV infection and all were sero-positive.
Conclusion: Vascular tumours are not uncommon and affect all age groups. Kaposi sarcoma associated with HIV infection in our environment needs to be emphasized.
Key words: Vascular tumours; Haemangioma; Kaposi sarcoma; Histopathological pattern.
