Of 65 patients with intrathoracic
metastases
from melanomon, 35 had metastasis to hilar or mediastinal nodes. In 28 of these 35, hilar and mediastinal lymph node enlargement was radiographically visible, hilar node enlargement was more commonly seen than mediastinal node enlargement. Pulmonary nodules were demonstrated radiographically in 25 of the 28 patients. Although lymph node enlargement was often asymmetric, symmetric hilar adenopathy mimicking
sarcoidosis
occurred in five of the 28 patients. Seven patients had unilateral involvement of lung and hilar and mediastinal nodes. In patients with melanoma, indirect metastatic spread via pulmonary nodules to hilar and mediastinal nodes may account for the frequent association of node
metastases
with lung nodules, the occurrence of intrathoracic adenopathy in the absence of extrathoracic node
metastases
, and the common finding of unilateral lung and nodal disease.

Fifty-one lymphograms were performed in children; the indications, technique and results are discussed. Indications are the search for retroperitoneal involvement in
lymphogranulomatosis
, lympho-sarcoma and reticulum cell sarcoma; in the search for
metastases
from malignant tumours, particularly abdominal neuroblastoma, soft tissue sarcomas of the abdomen and lower extremities, testicular tumours and malignant melanomas and finally, for primary lymph-oedema and lymphangiomas. Technique is the same as for adults, but requires particular manual dexterity. Children under six years require general anaesthesia. Amongst 28 children with malignant lymphomas, pathological changes in the retroperitoneal lymph nodes were found in seven. In six, this resulted in a change of the staging. Five out of 16 lymphograms in children with malignant tumours showed evidence of lymph node
metastases
. All six lymphangiograms in children with lymphoedema and lymphangiomas were abnormal.

A short survey is given on description and evaluation of progress and developmental trend of laparoscopy. Important technical improvements are the cold light via the glass fibre light conductor, optics of high value, the colour photography with electronic flash-light, colour films and colour television, new accessory instruments and belongings. Now as ever hepatomegaly and splenomegaly, jaundice, ascites, portal hypertension, suspicion of cirrhosis and
metastases
are regarded as main indications. The laparoscopy deserves a greater consideration in unclear abdominal symptoms, in gynaecological diseases, for the proof of the affection of liver and spleen in
lymphogranulomatosis
,
sarcoidosis
, tuberculosis (with aimed liver biopsy). The endoscopic retrograde cholangiopancreatography in the differential diagnosis of the jaundice competes with the laparoscopy, but it is not able to supersede it. The laparoscopic judgment of the pancreas and the importance of visible changes of the fine structed. Among the contraindications of the laparoscopy the hiatal hernia has lost its significance.

In two women who had undergone radiation therapy at ages one and eleven years, respectively, carcinoma in a hypoplastic breast developed. Each patient was treated by radical mastectomy. One patient is presently being followed without evidence of
metastases
; the other died of
sarcoidosis
following thoracotomy. A history of irradiation, hypoplasia and microscopic findings compatible with radiation changes suggests that these two cases of carcinoma may be radiation-induced.

In human tumors (cancer of the liver, stomach,
lymphogranulomatosis
of lymphnodes,
metastases
in lymphnodes, ascites ovarian tumor cells) the authors studied the content of enzymes participating in glycogen biosynthesis through uridine diphosphateglucose mechanism--UDPG-glycogensynthetase, UDPG-pyrophosphroylase, phosphoglucomutase. As a rule, in human tumor cells the amount of glycogen and the activity of enzymes of its biosynthesis is decreased, the more the higher proliferative activity and autonomization of tumor cells.

Multiple, large metastasis-like, nodular lesions (LNL) are a rare manifestation of acute/subacute pulmonary
sarcoidosis
. It has previously only been described in American series and all patients but one have been Negroes. In order to estimate the frequency of LNL in a Danish series, 126 consecutive patients with intrathoracic
sarcoidosis
were examined with regular follow-up for 1/2-5 1/2 years. LNL simulating pulmonary
metastases
was found in two cases, a frequency corresponding to the American figures. In both cases pulmonary infiltrations disappeared with 3/4 and 1 1/4 years, respectively. In one case a normal chest roentgenogram was obtained 6 weeks before the onset of LNL. The importance of biopsy is emphasized.
Sarcoidosis
with LNL appears to have a favourable prognosis in many cases.

Malignant disorders may produce neuromuscular syndromes in a variety of ways, for some of which it is still difficult to determine the exact pathophysiology. In the myopathic and neuropathic disorders, one possible explanation is that they are due to a virus such as is found in the rare "progressive multifocal leukoencephalopathy". This is seen in association with the malignant lymphomas and with other conditions such as
sarcoidosis
where immune responses may be altered by either the disease or the treatment. No viral material has been found in the nonmetastatic neurological disorders apart from progressive multifocal leukoencephalopathy. An alternative theory is that there may be an autoimmune process, the nervous system sharing some antigenic determinant with the neoplasm (Urich, 1967). The prognosis in the paraneoplastic neurological disorders is usually poor. As well as the direct threat to life posed by the malignant disease, when the neurological disorder is due to destruction of neurones (for instance cerebellar degeneration or sensory neuronopathy) recovery of function is impossible. Spontaneous remissions have been recorded in cases of proximal muscle weakness and sensorimotor neuropathy, but it is difficult to know whether the remissions have been truly spontaneous or related to treatment (excision of the neoplasm or administration of steroids). Further immunological and virological studies will probably reveal the answers to some of the outstanding problems. In the meantime the clinician must continue to investigate patients with muscular weakness for evidence of an occult neoplasm, and to repeat investigations if no other cause for the neurological disorder is found. Also, in patients with known malignant disease, apart from trying to differentiate forms of neuromyopathy from the effects of
metastases
the various metabolic disorders must be considered because the therapeutic possibilities are a little more promising in the paraneoplastic endocrine disorders. Ross (1975) wisely said that "cancer has replaced syphilis as the great imitator".

A case of
sarcoidosis
of the mediastinal lymph nodes with concomitant teratoembryonal carcinoma of the testis is presented. It is important to differentiate these entities from mediastinal
metastases
of testicular tumors and testicular
sarcoidosis
, respectively. We favor mediastinal biopsy in appropriate cases, in addition to testicular exploration.

Two cases of vertebral
sarcoidosis
in pediatric patients are presented. All such patients reported have been black, 13-15 years old, and have a history of back pain. Radiographs of the involved vertebrae show primarily lytic destruction with sclerotic borders in some of the lesions. Fungal infections, tuberculosis, pyogenic osteomyelitis, Hodgkin's disease and
metastatic disease
must be considered in every patient with vertebral
sarcoidosis
.

Thirty-eight cases with direct or indirect signs of hilar masses were investigated by roentgenologic, radioisotopic and surgical methods. Reasonable correlation between tomography and scintigraphy was confirmed, substantiating their complementary nature. Bronchogenic carcinoma of the central airways was most frequent among the hilar masses. Masses as well as other involvement of the bronchovascular structures of the hilum on conventional tomography were confirmed by the gallium-67 scan, and inhalation and perfusion scintigraphy. Some cases which simulated bronchogenic carcinoma were presented. Hilar masses without destruction of the bronchovascular structures showed normal inhalation and perfusion scintigrams with positive gallium-67 accumulation. These lesions were
metastatic cancer
, malignant lymphoma, and
sarcoidosis
. If these diseases involve the airways and the vessels of the hilum, differentiation from bronchogenic carcinoma may naturally be difficult.
