Mineralizing pulmonary elastosis is a result of chronic alveolar hemorrhage forming iron encrustation of a pulmonary elastic tissue. It has been reported as a complication of some diseases such as bronchiectasis, idiopathic pulmonary hemosiderosis, and cardiac failure. It is extremely rare to occur with a giant cell carcinoma as we experienced. A 59 year-old man visited our hospital for cough and blood tinged sputum. A chest CT scan revealed 10 9 6 cm sized round mass in the left upper lobe. He had lobectomy of left upper lobe, but died of respiratory failure at the postoperative eighteenth day. The lung showed a necrotic tumor and a yellow tan consolidation around the mass. Microscopically, the tumor was composed of nests or syncytia of large bizarre cells and tumor giant cells, and was diagnosed as a giant cell carcinoma. Interestingly, in the surrounding lung parenchyma there were a lot of foreign body type giant cells phagocytizing iron encrustated elastic fibers, which were easily identified by elastic van Gieson and prussian blue stains. Those degenerated elastic fibers appeared in pulmonary interstitial tissue as well as blood vessel walls. The authors concluded tumoral hemorrhage and necrosis resulted in mineralizing pulmonary elastosis.

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.

Diffuse-type giant cell tumor is relatively rare than localized giant cell tumor. Moreover, diffuse type giant cell tumor is common in intraarticular area, rarely occurs at intramuscular or subcutaneous layer. We experienced 1 case of giant cell tumor within the deltoid muscle. So we report this case with review of the literatures.
