Skin tumors at the Lagos University Teaching Hospital, Nigeria.

INTRODUCTION

Skin tumours can be malignant or benign. Skin cancer is the most common malignancy among Caucasians and noted to be rare in Africans and negroid skin. In view of the rarity of skin cancers in Africans, there is delayed diagnosis; and consequent advanced presentation and poor prognosis.

OBJECTIVE

This is to document the frequency of skin tumours (benign and malignant) from a 7-year review (January 2001 to December 2007) of histology reports of all skin samples seen at the pathology department of the Lagos University Teaching Hospital.

METHODS AND MATERIALS

Reports of all skin samples seen at the pathology department between January 2001 and December 2008 were reviewed. The frequencies of various skin tumours (both benign and malignant) were determined and the result displayed using frequency tables.

RESULTS

Skin tumours represented 19.8% of all reports made on skin during the study period. One hundred and twenty one (68.7%) were benign tumours while 55 (31.2%) were malignant tumours. There is a female preponderance for both malignant and benign tumours. The male to female ratio was 1:1.28 for benign tumours and 1:1.39 for malignant tumors. Squamous cell carcinoma (SCC) was the commonest malignant tumor, followed by malignant melanoma, Kaposi's sarcoma and dermatofibrosarcoma protuberans. Cutaneous papilloma was the commonest benign tumour.

CONCLUSION

A wide range of skin tumours, benign and malignant were documented; hence there is need for more vigilance in order to diagnose them early.
