“…As to etiologic factors in the evolution of melanoma, H ewer [7] and others suggested the role of trauma, especially in subjects walking bare foot. In modern Japan, walking without shoes or sandals outside the house is extremely rare; yet the sole of the foot is one of the most common sites of the neoplasm.…”

“…The incidence of malignant melanoma of the mucous membranes is quite low among Caucasians [1,3,16,19], whereas it varies in negro populations [20], being especially common among native African negroes [2,12], Apart from the absolute incidence, mucous membranes and non-pigmented skin, such as sole of the foot, are sites of predilection in colored populations including American negroes, African negroes, and Latin Americans [2,7,11,12,14,20]. As shown in the present survey, this tendency also exists among the Japanese.…”

Two hundred and twelve autopsied cases of malignant melanoma observed in Japan were studied as to incidence, primary sites, and mode of metastases, mainly from the point of view of geographic pathology. The overall incidence among all autopsy cases was 0.16%. Malignant melanoma in Japan seems to have some specific features such as: (1) a relatively low incidence of cutaneous and a relatively high incidence of non-cutaneous melanoma; (2) lower extremities, especially the sole of the foot, being the primary site of predilection of cutaneous melanoma; and (3) high incidence of mucosal melanomas including those of nasal, paranasal, and oral cavities, the latter being more common in females than in males. These findings are similar to those observed among other colored populations and differ from those noted in Caucasians. The higher incidence of the tumor in the less sunny part of Japan suggests that the role of sunlight in the causation of melanoma is still a moot question.

“…However, this factor suggested by Hewer (1935) cannot be the whole explanation as the same predilection for the sole is encountered in American Negroes, many of whom have sedentary jobs and most of whom wear shoes (Steiner. 1954).…”

Summary.-Superficial cancer in the Sudan accounted for 17-2% of all malignant tumours examined histologically during the period 1962-72 inclusive. Of the 4 pathological types studied, squamous cell carcinoma was the commonest (63.3% of all superficial cancers) followed by malignant melanoma (18*8%) and basal cell carcinoma (14-9%) whilst Kaposi's sarcoma formed only 3%o of the total. Generally, twice as many cases occurred in males as in females, with the exception of Kaposi's sarcoma where all the patients were males. Although a relatively high proportion of cases occurred in the young age groups, the age-specific incidence was noted to increase with age. Similarities and differences in the anatomical site of tumours compared with European and African series were noted. Certain differences emerged in the geographical distribution of these tumours in the Northern and Southern regions of the Sudan-regions which differ both ethnologically and geographically-thus suggesting possible roles played by racial and environmental factors in this respect.
