Bone metastasis of hepatocellular carcinoma appears to be peculiar when clinical manifestation of liver disease is not apparent, and initial diagnosis of metastatic hepatocellular carcinoma by fine needle aspiration cytology is rarely obtained. We experienced a case of 45-year-old man with metastatic hepatocellular carcinoma in the sacrum, which was diagnosed by fine needle aspiration cytology. The intrahepatic mass, measuring 1.2 cm in diameter and kept unchanged in size for two years, was never proved to be hepatocellular carcinoma histopathologically. The aspirated neoplastic cells were mostly in sheets, showing abundant acidophilic cytoplasm and large, round, centrally located nuclei with single, prominent acidophilic mucleoli. In the cell block section, diagnosis of metastatic well-differentiated hepatocellular carcinoma was made without difficulty, and definite trabecular fashion with sinusoidal endothelial cell lining was found.

In the past, parasitic diseases were a major problem in public health in Korea. In recent years, however, nematodiasis that used be prevalent are no longer a serious problem. Instead some cestodiasis, particularly cysticercosis and sparganosis have become comparatively more important in recent years. Parasitic infestation of soft tissue is presented as a subcutaneous nodule or mass with nonspecific clinical manifestations. We experienced 4 cases of parasitic infestation in the soft tissue diagnosed by fine needle aspiration (FNA). Three out of four cases were histologically confirmed, two out of four cases were cysticercosis and one case was confirmed as sparganosis. FNA may be useful in providing a diagnosis in cases of parasitic infestation.

This is a retrospective review of fine-needle aspiration cytology(FNAC) smears of 153 cases of thyroid disease performed during August 1989 to July 1995, which were confirmed histologically following surgical operations. FNAC results showed 63 cases(41.2%) of adenomatous goiter, 45 cases(29.4%) of papillary carcinoma, 29 cases(19.0%) of follicular neoplasm, 4 cases(2.6%) of follicular variant of papillary carcinoma, 4 cases(2.6%) of Hashimoto's thyroiditis, 4 cases(2.6%) of $H\ddot{u}rthle$ cell neoplasm, 2 cases(1.3%) of medullary carcinoma and one case(0.7%) each of subacute thyroiditis and of anaplastic carcinoma. The overall accuracy of cytological diagnosis was 83.7%. These data strongly suggest thyroid FNAC is a reliable preoperative diagnostic tool, but FNAC has been less valuable in the diagnosis of follicular lesions than any other disease of the thyroid. Adenomatous goiter was not infrequently interpreted as follicular neoplasia that requires surgery for diagnostic conformation and vice versa. The following findings are considered to be compatible with follicular neoplasm: 1) microfollicles, 2) nuclear grooving, 3) irregularity of nuclear membrane, and 4) irregular arrangement or crowding of follicular cells in groups. The FNAC criteria of adenomatous goiter are as follows: 1) atrophic follicular cells, 2) presence of macrophages, 3) abundant colloid, and 4) large follicles. It is recommended that aspiration of thyroid lesions in order to analyse with critical clinico-pathological approach and surgery is considered only for nodules that are clinically suspicious or unresponsive to hormone therapy or when a diagnosis of follicular neoplasm is made.

Medullary carcinoma (MC) of the breast is an uncommon histologic form of infiltrating ductal carcinoma and the cytologic features of MC are not well delineated. We recently experienced a case of fine needle aspiration cytology of MC of the breast. The characteristic cytopathologic features were cellular aspirate consisting of large, pleomorphic cells in background of many single to clusters of lymphocytes.

Cathepsin D is a protease which is known to facilitate invasion and metastasis of breast carcinoma. Overexpression of cathepsin D is associated with poor clinical outcome and biologic aggressiveness of the breast cancer. We underwent immunocytochemical assay(ICA) for cathepsin D in fine needle aspiration cytology(FNAC) specimens from the breast carcinoma and benign breast diseases. In FNAC specimens cathepsin D was expressed in 21(42.9%) out of 49 cases of invasive ductal carcinoma, whereas negative result was observed in all 15 cases of benign breast diseases including 7 fibroadenomas, 6 fibrocystic diseases, and 2 benign ductal hyperplasias. Among the 11 FNAC specimens from ductal carcinoma in situ(DCIS), cathepsin D was expressed in 3 cases(27.3%). In FNAC specimens immunocytochemistry for cathepsin D showed positive result in 24 out of 60 carcinomas(sensitivity, 40%) and negative result in 15 out of all 15 benign breast diseases(specificity, 100%). No significant correlation was noted between cathepsin D expression in FNAC specimen and clinicohistological characteristics of the breast carcinoma, such as hormone receptors and cell differentiation. In conclusion, ICA of cathepsin D in FNAC specimens thought to be a good adjunct to differentiate malignancy from benign breast diseases.

Pilomatricoma is a well defind and characteristic entity histologically, but this tumor may be encountered during aspiration biopsy of subcutaneous mass, and is, occasionally, confused with other neoplasms, particularly squamous cell carcinoma, basal cell carcinoma, and epidermal inclusion cyst. Recently, we have experienced a case of pilomatricoma diagnosed by aspiration biosy. The smear of the aspirate revealed anucleated "ghost" squamous cells, basaloid or basophilic squamous cells and nucleated squamous cells, which lack nuclear features of malignacy. These findings are consistent with pilomatricoma.

Urine cytology is of limited value in the diagnosis of renal cell carcinoma with reported detection rates of $0\sim80%$. The aim of this study is to demonstrate the usefulness of urine cytology in renal cell carcinoma. In the eleven histologically proven cases of renal cell carcinoma, urinary smears were reevaluated. The cytologic results were as follows; positive for malignant cells in 3 cases(27%), suspicious in 2 cases(18%) and negative in 6 cases(55%). The average diameter of the tumor of the 5 cases reported as positive or suspicious for malignant cells was 9.7cm and 3 had invaded the renal pelvis. The other 6 tumors, reported as negative, were 5.7 cm in average diameter and one of them showed involvement of the renal pelvis. These results suggest that urine cytology is considered unsatisfactory in the early defection of renal cell carcinoma. However, careful examination of urinary smear could improve the detection rate especially in more advanced cases involving the renal pelvis as well as those of larger tumors.

Thirty cases of Kikuchi's lymphadenitis, diagnosed by fine needle aspiration cytology, were reviewed to determine the main cytologic features helpful in reaching a diagnosis. The patients(mean age 26.6 years, male: female = 1:3.8) presented with lymphadenopathy (cervical 24, submandibular 3, and axillary 1) with or without fever and local tenderness. Excisional biopsy was done for confirmation in 5 cases and the remaining 25 cases showed the similar cytologic and clinical features. In the aspiration smears of all cases, there was a heterogenous celluar mixture including frequent extracellular karyorrhectic nuclear debris, phagocytic histiocytes, plasmacytoid monocytes, and a variable number of polymorphous lymphocytes such as immunoblasts, activated large lymphocytes, and small mature lymphocytes. The characteristic cytologic features of Kikuchi's lymphadenitis were the following: (1) frequent extracelluar karyorrhectic nuclear debris in the background : (2) phagocytic histiocytes with eccentrically placed crescentic nuclei and abundant pale cytoplasm containing phagocytized karyorrhectic debris : (3) plasmacytoid monocytes, which were medium-sized cells with eccentrically placed round nuclei and amphophilic cytoplasm : (4) no neutrophilic background.

Small cell carcinoma of the lung is characterized by cells with finely stippled chromatin and scanty cytoplasm as well as a particularly aggressive clinical course and favorable response to the chemotherapy. Recently percutaneous fine needle aspiration (FNA) biopsy has become both widely established and highly respected for the diagnosis of lung cancer. However metastatic small cell carcinoma of lymph node should be cytologically differentiated from the small round cell tumor of particular sites, especially malignant lymphoma, because small ceil carcinoma of classic oat cell type nay simulate small cell non-Hodgkin's lymphoma. We report five cases of metastatic small cell carcinoma of in-termediate cell type diagnosed by FNA of the enlarged lymph nodes of the neck and axilla. The cytologic smears contained diffuse small neoplastic cells larger than lymphocytes with dense, pyknotic nuclei and extremely scanty cytoplasm. Apparently viable large tumor cells have vesicular nuclei with granular, sometimes very coarse chromatin. The characteristic cytologic features of small cell carcinoma as compared to malignant lymphoma were as follows.: 1) small cells with dense pyknotic nuclei are evenly distributed in the background of apparently viable larger tumor cells, admixed with mature lymphocytes and phagocytic macrophages. 2) small loose aggregates of cells with nuclear melding are indicative of small cell carcinoma rather than non-Hodgkin's lymphoma. 3) the cytoplasmic and nuclear fragments of tumor necrosis are more dominant in the smears of small cell carcinoma. 4) nuclear membrane and nucleoli are generally indistinct in small cell carcinoma due to condensation of chromatin.

폐암 치험 73례: Alveolar cell carcinoma 를 중심으로

손광현,이남수,고일향,Sohn, Kwang-Hyun,Lee, Nam-Soo,Ko, Il-Hyang 대한흉부심장혈관외과학회 1979 Journal of Chest Surgery (J Chest Surg) Vol.12 No.4

During the period of 4 years from August 1975 to August 1979 one hundred and forty seven cases of lung cancer were seen at Paik Foundation Hospital in Seoul, Korea. Among these 147 cases, 104 patients had primary carcinoma of the lung and the remainder was metastatic carcinoma to the lung. Among these 104 primary carcinoma patients, 73 cases were proven histologically as primary carcinoma of the lung. There were three cases of alveolar cell carcinoma [Table 1 ]. This clinical observation is based on those 73 cases including three case reports of the alveolar cell carcinoma. 1. Peak incidence was observed in the 5th decade of life. Male to female ratio was 2 to 1 [Fig. 1]. 2. Pathological classifications were as follows: epidermoid carcinoma, 24 cases [32.9%]; undifferentiated carcinoma, 20 cases [27.4%]; adenocarcinoma, 15 cases [20.5%]; bronchioloalveolar carcinoma [5.5%] and positive cytology, 10 cases [13.7%] [Fig. 2]. 3. Evidence of inoperability was observed in 55 patients [75% of the 73 cases] [Table 3]. 4. Among those 73 cases, operability was evaluated in 18 patients or 25%. One patient refused operation and 17 patients [23.6%] were explored. In 11 [15%] out of 17 patients, thoracotomies were performed. Six cases were pneumonectomies and 5 cases were lobectomies or bilobectomies [Fig. 3]. 5. First case of alveolar cell carcinoma was a 46 year-old housewife complaining of cough and hemoptysis for one year. The plain chest X-ray and bronchogram showed characteristic pictures as Figures 4 and 5. A pneumonectomy was carried out. Histologically, a beautiful alveolar carcinoma consisted of the characteristic tall columnar epithelial cells, which were lining the alveolar spaces as seen in Figures 6, 7, 8, and 20. 6. In the second case of 41 year old male, predominant clinical feature was single, well defined mass in the right lower lobe [Fig. 10 and 11] on chest X-ray. Bilobectomized specimen showed fragile, soft and hard tissue containing mucoid secretions and focal yellowish necrosis with pigmentation on cut surface [Fig. 12]. Slides showed tumor cells lined up along the alveolar septa with papillary projections [Fig. 13 and 14]. 7. Third case of alveolar cell carcinoma was a 50-year-old housewife with hemoptysis. An outstanding clinical picture was a round to lobulated mass in the right upper lobe [Fig. 16]. She is living now, 2 years and 1 month post-operatively, but has arrived at terminal stage with military nodular disseminations to the contralateral lung [Fig. 19].
