Clinical & Histopathological Study on Skin Tuberculosis During 5 Years (1970~1974) / 대한피부과학회지

ABSTRACT

This clinical & histopathological study was performed with 48 cases of cutaneous tuberculoeis among 44460 cases of out patient in Dermatologic clinc of St. Mary's hospital, Catholic Medical College, from 1970 to l974. These 48 cases were consistent with skin tuberculosis in histological and clinical findings. The results are follows. I. Clinieal observation. 1) The incidence of skin tuberculosis is 0. 1%, among 44460 cases of out patients. 2) Localized type of skin tuberculosis is l. 4 times more than disseminated type. 3) The ratio between male and female is 2. 4 l. 4) The age of onset is different from type to type, but 70. 8% of all cases occured before the age of 29. 5) Common skin tuberculosis is Erythema induratum (31. 3%),Lupus Vulgaris (20.8%) and Papulonerotic tuberculid (12.5%)II. Histopathological observation. 1) Only 12. 5% of the cases showes typical structure of tubercle in dermis and subcutis. 2) Caseation necrosis showes in 47% and their amounts are different between the types. 3) About 75% of cases showes Langhans giant cells but some of the cases show foreign body giant cells in tubercle or tuberculoid structures. 4) Vessels are involved in all of the cases. Main changes are wall proliferation, degeneration and perivascular infiltration. 5) A.F.B. stain showes negative in all cases.
