An epidemiological study of malignant melanoma in Puerto Rico was done by reviewing the Puerto Rico Cancer Registry for all melanoma cases reported between the years 1981 to 1987. A total of 367 new cases were documented with the annual incidence ranging from 1.20 to 2.12 per 100,000 inhabitants with a mean of 1.59. Most of the patients were between 40 and 80 years of age with a peak in the sixties. Nearly one half of the tumors were located on the extremities, most notably on the feet, sharing this predilection with Blacks and Japanese. The most frequently recognized clinico-histologic type was the superficial spreading melanoma followed by the acral lentiginous, the nodular and the lentigo maligna melanoma. Nearly one third of the total cases were not classified according to the histologic type, while Clark's levels and Breslow's thickness were not reported in 44 and 84% of the cases, respectively. When compared to a previous study during 1977 to 1980, the average annual incidence of new cases increased from 0.92 to 1.59 per 100,000 documenting an increased incidence of the condition in our population, but not as significant as that registered in the United States.
通过查阅波多黎各癌症登记处1981年至1987年间报告的所有黑色素瘤病例，对波多黎各的恶性黑色素瘤进行了一项流行病学研究。共记录了367例新病例，年发病率为每10万居民1.20至2.12例，平均为1.59例。大多数患者年龄在40至80岁之间，60多岁时达到峰值。近一半的肿瘤位于四肢，最常见于足部，黑人和日本人也有这种偏好。最常被认可的临床组织学类型是浅表扩散性黑色素瘤，其次是肢端雀斑样痣性、结节性和恶性雀斑样黑色素瘤。近三分之一的病例未按组织学类型分类，而分别有44%和84%的病例未报告克拉克分级和布雷斯洛厚度。与1977年至1980年期间的一项先前研究相比，新病例的年平均发病率从每10万人0.92例增加到1.59例，表明我们人群中该病的发病率有所增加，但不如美国登记的那样显著。
