Abstract

Outdoor and industrial occupations in the southern Transvaal do not increase the incidence of any skin tumour excepting that of squamous cell carcinoma. However, they accelerate the onset of solar keratoses and squamous and basal cell carcinomas. A fair, sun-sensitive skin, red hair and blue eyes are more important factors predisposing towards the development of skin cancer. Unduly large numbers of seborrhoeic keratoses were found in association with polyps, and of intradermal naevi with both cavernous haemangiomas and lentigines. A high proportion of solar keratosis was found in both squamous cell carcinoma and Bowen's disease, and of basal cell carcinoma in superficial basal carcinoma, but the reverse associations were not significant.

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.

Bowen's Disease

Bowen's disease is thought of as an easily-treatable early stage of skin cancer, characterized by red, scaly patches on the skin. Discover the latest research on Bowen's disease here.

Carcinoma, Squamous Cell

Basal cell carcinoma is a form of malignant skin cancer found on the head and neck regions and has low rates of metastasis. Discover the latest research on basal cell carcinoma here.
