Clinical Studies on Malignant Cutaneous Tumors
Abstract
- The clinical studies were made on 40 cases of malignant cutaneous tumors who visited to Department of Dermatology, Kyungpook National University Hospital during last 6 years from 1967 to 1972. 1) Among 40 cases, 23 were squamous cell carcinomas, 10 basal cell carcinonias, two mycosis fungoides, one Hodgkins disease, one malignant melanoma, one angiosarcoma, one fibrosarcoma, and one metastatic adenocarclonoma. 2) The patient with malignant tumors were increasing by the year, being 0.06% of total out patients in 1967 but increased to 0.64% by 1971. 3) Squamous cell carcinomas were seen above the age 30 but basal cell carcinomas were seen above the age 40. Mycosis fungoides and malignant melanoma were seen in 20th of age, while Hodgkins disease, angiosarcoma, fibrosarcoma, and metastatic adenocarcinoma were seen in 50th of age. 4) The ratio of squamous cell carcinoma to basal cell carcinoma was 2.3:1, contrary to higher incidence of basal cell carcinoma than squamous cell carcinoma among caucasians. 5) Among 23 cases of squamous cell carcinoma, 7 cases were derived from Bowens disease, 4 cases were from chronic burn scar, two from senile keratosis, one from tropic ulcer, and remaining 9 were not able to elucidate its cause. 6) The predilection sites of squamous cell carcinoma were four extremities particulary on lower extremities, while basal cell carcinomas were on the face predominantly. 7) Among 10 cases of basal cell carcinomas, 8 cases were ulcerative form and the rest of two were nodular form. 6 cases showed dark pigmentation in the lesions sugge stive of pigmented basal cell carcinoma but only 3 of them were proved to be true pigmented form histologically. 6 cases showed solid type of basal cell carcinoma and 2 showed pigmented type among 8 cases of ulcerative form. Those two cases of nodular form, one showed pigmented type and the other adenocystic type histologically.
