Serum Immunoglobulin (Ig)A, IgG, IgM, levels were measured in 99 coal workers' pneumoconiosis (CWP) patients and 12 healthy coal workers and 9 non-miners to compare with each group by the radiological categories, its complications and working period in coal mine. Serum were measured by nephelometry. The findings were as follows: 1) Serum IgA levels were significantly different between three groups of CWP patient, healthy coal worker and non-miner (mean+/-standard deviation: 226.4+/-87.7, 221.3+/-45.1, 170.1+/-65.7 respectively). 2) There were no significant differences of Ig levels among radiological categories of CWP. 3) There were no significant differences of Ig levels among simple pneumoconiosis and its complicated disorders. 4) The three Ig levels were slightly increased in the group of mining years less than 20 years (IgA: r=0.1869, p<0.10 IgG: r=0.2902, p<0.05 IgM: r=0.2889, p<0.05).

BACKGROUND: Becker's mealanosis is not an uncommon entity, and many cases are probably not reported because the diagnosis is usually made clinically and the condition is benign with cosmetic significance only. the etiology remains obscure. OBJECTIVE: The purpose of this study is to establish the clinicopathologic characteristics of Becker's melanosis in Korean. METHODS: Thirty-six patients with Becker's melanosis were retrospectively studied. RESULTS: The clinical and histopathologic findings observed in our cases were similar to previous reports except for the following. Nine patients(25%) had abnormal findings in their hair follicles : dilatation of the infundibular portion filled with abnormal keratin, Pityrosporum orbiculare and bacteria(19.4%); formation of intrafollicular cyst(5.6%). Three patients(8.3%) had granulomatous infiltration. Twenty-two patients(61.1%) had increased smooth muscle bundles. CONCLUSION: The findings associated with dermal hair follicles may be related to the pathogenesis of Becker's melanosis.

Since Oct. 1, 1983 until April 15, 1986, authors analyzed variable combined imaging diagnosis andhistopathologic correlation for confirmed 100 breast carcinoma among 2773 patients whom authors took care of them.1. Incidence of female breast carcinoma was 3.6% among 2773 patients who visited Yong Dong Severance Hospital, andoverall breast carcinoma occupied 29.7% among 337 confirmed breast diseases. 2. Prevalent cancer age for Koreanwomen breast carcinoma was ages between 40-49 years old(42%) however authors experienced 5% breast carcinoma amongtwentieth, and 22% breast carcioma among thirtieth. 3. Most common histopathologic type for breast carcinoma wasinfiltrating ductal carcinoma, scirrhous type(65). And most common breast parenchymal pattern related to breastcarcinoma was DY pattern(42%) followed by N1 pattern(25%). 4. Common film mammographic findings of breastcarcinoma were: ill defined bordered mass(68.4%), spiculation of mass(82.9%), vessel dilatation (59.8%) and thencalcification (44.4%). 5. Frequently visible ultramammographic findings were; irregular mass contour(79.6%),nonuniform internal echoes(87.0%), and posterior wall shadowing (86.0%). 6. Trials of above combined imagingmodalities for breast carcinoma resulted in his sensitivity of diagnosis(93.3%).

It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.

We observed 2 cases of multiple trichoepithelioma, which occured in 25-year- old male and 20-year-old female. They visited our department for multiple skin rashes on the face of 8 years duration in male and 7 years' duration in female patient. Both of them have similar skin lesions characterized by multiplel waxy gshiny, skin colored, firm papules scattered on the nasolabial folds, both eyelids and forehead. Each one of them has a history of similar skin lesions in the family. Literatures are briefly reviewed for discussion of clinical and histopathologicl findings in this disease.
