Extraadrenal pheochromocytomas developed from the paraganglia other than adrenal medulla are uncommon tumors. Such lesions have been reported that as much as 10% of retroperitoneal paragliomas arise outside the adrenal gland. But their incidence and prognosis are changing partly as a result of progression in developmental mechanism, diagnostic tools and concepts including ultrastructure, immunohistochemistry. The ultrastructure of chromaffine neoplasm from adrenal and extraadrenal tissues has been studied with chrarnaffine granule specificity and type of catecholamine content. With rare exceptions, extraadrenal chrornaffine tumor mainly has high concentration of norepinephrine which is suggested as dict relationship to numoruos electrone dense granular bodies in the cell cytoplasrn. High or intermediate level of epinephrine in tissue is associated with cytoplasmic granular bodies of much less density, Recently we experienced the exception, a case of norepinephrine secreting pheochrom-ocytoma in the organ of Zuckerkandl with epinephrine granules in cytoplasm and this discrepancy probably due to the plasticity

We describe unusual manifestations of congenital cystic adenomatoid malformation ( C.C.A.M.) of the lung, such as movable fungal ball-like intracystic blood clots and hemoptysis, which were detected in previously healthy 23 years-old woman. We identified blood clots only after left upper lobectomy and could not distinguish from fungal ball with radiographic methods. CCAM of the lung, rare and lethal form of congenital pulmonary cystic disease, was initially introduced by Ch'in and Tang in 1949. The histogenesis of this lesion is characterized by polypoid glandular tissue proliferation and overgrowth of mesenchymal elements due to cessation of bronchiolar maturation which occured in after 16weeks intrauterine period. In 80-95% of reported cases, the lesion was confined to a single lobe and there was no lobe and right and left lung predilection. The clinical presentation may be widely variable, ranging from intrauterine fetal death to late discovery in childhood with recurrent pulmonary infection. But there's no reports which were misdiagnosed with intracystic fungal ball. The treatment choice is lobectomy of affected lobe. There's a few case reports with rhabdomyosarcoma, bronchiolar cell carcinoma and myxosarcoma arising in CCAM patients. Therefore, early resection is recommended even if asymtomatic cases. We experienced a rare case of CCAM of the lung in 23 years old female, and there were intracystic fungal ball-like movable blood clots in lower portion of left lung. After left upper lobectomy was performed, now she is discharged and followed up without any complications.
