A chromophobic pituitary adenoma induced on BD IX-rats has been grafted on animals of the same strain. The transplanted tumour takes in 90-100%; it grows at a slow rate (in 7 months after grafting a weight of 7-20 g is attained). Tumour-bearing animals display
gigantism
and hypertrophy of adrenals; moreover, in 33% of cases, diabetes is observed. With non-diabetic animals, splenomegaly and marked leukocytosis are observed; immature white and red cells are present in the peripheral blood. Spontaneous regression of the tumour never occurs. After surgical removal, tumour regrowth and the formation of
metastases
are observed. Diabetes is characterised by pronounced hyperglycaemia, glucosuria, polyphagia and polydipsia. Histochemically, insulin cannot be detected in pancreas. Splenomegaly is never observed in diabetic animals. Transplanted adenoma frequently tends to stop growing. No recurrence is observable after extirpation. Spontaneous regression of the tumour sometimes occurs.
Gigantism
, hypertrophy of adrenals and diabetes are considered as consequences of growth hormone- and ACTH-secretion of the transplanted adenoma. At present the tumour is running in the 8th passage. It did not change its characteristics over a period of 5 years.

The present report is that of a 40-year-old woman admitted with hematemesis and epigastric pain. Endoscopy revealed a fungating mass in the lower esophagus. Esophageal brushing revealed clustered and single malignant cells with ample cytoplasm, large bizarre nuclei and prominent, irregular nucleoli; the chromatin was irregular with clumping at the nuclear borders.
Giant
multinucleated malignant cells were numerous. These cells had nuclear molding and abundant acidophilic cytoplasm. Autopsy findings included a large tumor in the lower esophagus and
metastases
to lung, liver and kidneys. Microscopically, the fungating esophageal tumor and
metastases
were composed of cyto- and syncytiotrophoblastic elements. Choriocarcinoma of the esophagus is a rarity, and only two cases were found in the literature. The diagnosis, however, can be achieved by brush biopsy since the characteristic cyto- and syncytiotrophoblastic cells can be readily identified, provided that the possibility of this ectopic occurrence is recognized.

Giant
Cell Tumours (GCT) of the Bone is one of the commoner primary bone tumours. Although considered a benign tumour, it does occasionally
metastasize
to the lungs. Treatment modalities vary according to the surgical staging and the site of the tumour. Treatment is further complicated when the tumour occurs in difficult locations like the sacrum. The paper includes a review of literature into treatment options and the presentation of 3 patients with sacral GCTs, one of which also has multiple pulmonary
metastases
from a "benign" giant cell tumour.

Giant
-cell tumor of the sacrum is rare. There were only a few reports of large series in the literature. From 1960-1988 a total of ten cases giant-cell tumor of the sacrum were treated in our Department. The average age of the patients was 34 years (with range of 19-49 years). The lesions located in the proximal parts of the sacrums in 8 cases, and in S3-5 in another 2 cases. of 10, 7 were treated with en bloc resection or subtotal resection. of the sacrum, and followed by irradiation in 5 of 7 cases (with range of 2000r-4500r). All the 7 cases were followed up without any evidence of local recurrence or distant
metastases
. The average follow-up period was 10.3 years (with range of 1.5-27.5 years). The rectal, bladder and sexual function were normal or restored. The other 3 cases, biopsied in 2, partially resected in 1, died less than one year after diagnosis. Comparing the died group with the survival group, we concluded that early diagnosis and thorough excision of the tumor are the two decisive factors for a favorable prognosis.

Giant
hemangiomas of the liver are clinically distinct from smaller and more innocent hemangiomas as they are more prone to complications. On imaging with ultrasound, they can also be readily confused with hepatoma,
metastatic disease
, or focal nodular hyperplasia. Nine giant hemangiomas (maximal diameter greater than 8 cm) were studied by scintigraphy and ultrasound. In all instances, the fill-in of the lesion on [99mTc]RBC scintigraphy indicated the diagnosis of hemangioma, adding specificity to the screening sonographic study. The pattern of fill-in on scintigraphy also appeared to be size dependent with lesions less than 11 cm in diameter equilibrating uniformly, while larger abnormalities intensified in centripetal fashion.

Thirty-five cases of benign cystosarcoma phyllodes, 13 cases of malignant cystosarcoma phyllodes, and ten cases of giant fibroadenoma were studied. The diagnosis of benign or malignant cystosarcoma phyllodes was based on a combination of histological features. Clinical and gross pathologic findings were not found to be useful in distinguishing between benign and malignant tumors.
Giant
fibroadenomas occurred primarily in black adolescents and were histologically distinct. Positive surgical margins were found to be the best predictor of local recurrence of benign or malignant cystosarcoma phyllodes. Systemic
metastases
occurred in only one case of malignant cystosarcoma phyllodes. Most benign and malignant cystosarcoma phyllodes may be treated by wide local excision with tumor-free margins.
Giant
fibroadenomas should be treated by simple excision to preserve normal breast tissue.

Most premalignant penile lesions should be completely locally excised.
Giant
condyloma frequently cannot be distinguished from fungating carcinoma and usually requires limited penectomy. Cancers other than epidermoid carcinomas are very rare and, except for basal cell carcinoma, have a generally poor prognosis. Prognosis of squamous cell carcinoma, however, depends on the stage of disease as determined by both local invasion and by involvement of inguinal nodes. The three-year survival rates for 55 patients were: stage I, 95 percent; stage II, 67 percent; stage III, 29 percent; and stage IV, zero percent. Most primary lesions were treated by partial penectomy, and no patient developed local recurrence. There is a significant discrepancy between initial clinical and histologic staging, due to the difficulty of determining lymph node
metastases
. Current methods of radiation therapy indicate that it has a role for management of primary penile cancer, especially in young men with small lesions. The management of inguinal lymph nodes is still debated. Although the reliability of the sentinel node biopsy has not been established, it may be appropriate in patients with noninvasive primary lesions and no detectable inguinal
metastases
. The need for immediate or prophylactic lymph node dissection in patients with invasive primary tumors is controversial. Successful management depends on careful and frequent follow-up examinations, with early intervention for suspicious adenopathy. In view of the poor prognosis for advanced lymph node
metastases
, we prefer to use early lymph node dissection when the primary lesion is deeply invasive. Limited bilateral pelvic lymph node dissection is associated with minimal morbidity and seems to be an appropriate prelude to groin dissection. Extensive pelvic
metastases
are a sign of incurability and abrogate the need for groin dissection. We prefer to perform the inguinal dissection at the time of lymph node dissection through a separate curve groin incision.

A 59-years old woman showed 5 years after the diagnosis of a sarcoidosis of stage II--III according to Wurm and Reindell an abdominal symptomatology in the sense of an ulcerous disease. Radiological, endoscopical and bioptical examinations revealed a small contraction of the antrum, an ulcus at first diagnosed as benign and an adenocarcinoma. In the resected part of the stomach were found noncaseating granulomas with Epithelioid cells and
Giant
cells as well as the adenocarcinoma. 1 1/2 years after partial resection of the stomach (B II) a recurrence of the carcinoma near the anastomosis and
metastases
in the lymphonoduli of the abdomen were found by autopsy. Thoracic of abdominal manifestations of the sarcoidosis could no longer be demonstrated.

In a review of 159 gallbladder carcinomas, we identified four unusual histologic types: oat-cell carcinoma (five cases), giant-cell adenocarcinoma (seven cases), intestinal-type adenocarcinoma (three cases), and adenocarcinoma with choriocarcinoma-like areas (one case). Oat-cell carcinomas were similar at light- and electron-microscopic levels to those previously described in other anatomic locations.
Giant
-cell adenocarcinomas coexisted with well-differentiated adenocarcinomas and exhibited transition areas. For these reasons, we believe that they originate from preexistent adenocarcinomas. Intestinal-type adenocarcinomas consisted predominantly of goblet cells or glandular structures similar to colonic crypts. These four histologic types of gallbladder carcinoma were more common in women than in men, usually coexisted with lithiasis, and had a highly aggressive clinical behavior. Fourteen patients died of direct local extension and
metastases
, and two were unavailable for follow-up.

We report an 18-yr-old youth with a metastatic foregut carcinoid tumor, Cushing's syndrome, and hypersomatotropic
gigantism
. Administration of cyproheptadine caused a dramatic fall in urinary cortisol excretion and plasma ACTH levels associated with clinical remission of the Cushing's syndrome. GH secretion was not affected by cyproheptadine administration. Ectopic ACTH secretion was confirmed by RIA of tumor extracts and immunohistochemical demonstration of ACTH-containing cells in hepatic
metastases
. There were two sources of GH production demonstrated in this patient. Ectopic secretion of GH by the carcinoid hepatic
metastases
was documented by both RIA and immunohistochemical techniques. A somatotrophic pituitary tumor was also present. The histological characteristics of this tumor suggest adenomatous hyperplasia rather than de novo neoplastic change as the likely mechanism of its pathogenesis. GH releasing factor-like activity was demonstrated in extracts of plasma and in extracts of the carcinoid tumor. We conclude that cyproheptadine exerted an effect on the ectopic ACTH-producing cells but not on the ectopic GH-producing cells or on adenohypophyseal GH secretion. Production of a GH releasing factor-like activity by the carcinoid tumor may have caused the pituitary somatotrophic tumor.
