A case report is given on a male patient who was 52 years old when he died. 9 years ago a nephrectomy was performed because of a densely-packed mesenchymal tumor of the adipose tissue of the pelvis renalis. 7 years after the surgical intervention he suffered from several hypoglycemic crises. An operation was performed, and 2 large tumor nodes were removed from the greater omentum. A retroperitoneal relapse was inoperable. Nevertheless, the disorder of the carbohydrate metabolism disappeared after the operation. At the autopsy, one year later, a large retroperitoneal tumor with
metastases
in the lymph nodes was found. The neoplastic growth was classified as a malignant histiocytoma, and the hyperglycemia was taken as a
paraneoplastic syndrome
(Doege-Potter).

There is evidence that patients under 30 years of age with nasopharyngeal cancer present a somewhat different form of disease than patients of the older age group. Serum immunologic reactivity in the former was quantitatively different. Histologically, tumors in the younger age group are always of the undifferentiated type, and clinically, the disease is aggressive, characterized by frequent bone and lung metastases. The lymphatic spread into the mediastinum is accompanied by a
paraneoplastic syndrome
consisting of finger clubbing and hypertrophic osteoarthropathy, which is reversible after successful therapy. High rates of recovery have been obtained, even in the presence of advanced disease or
metastases
. This warrants a radical and persistent radiotherapeutic and or chemotherapeutic approach.

Carcinoma of the bronchus can produce several polypeptide hormones and therefore has the capacity to cause most syndromes of endocrine hyperfunction. All pituitary hormones can be synthesized ectopically; furthermore, the production of hormones from the hypothalamus (CRF), the placenta (HCG, HPL) and the C-cells of the thyroid (calcitonin), as well as parathormone and prostaglandins has been described. The
paraneoplastic syndrome
may often be more dangerous for the patient than the tumor growth itself, and can lead to early death. On the other hand, it may allow the early detection of an unsuspected tumor. The ectopic hormones and other nonendocrine proteins and peptides can be used as tumor markers, and can demonstrate the effect of treatment and early recurrence or
metastases
. An ideal tumor marker should have the following characteristics: 1. production exclusively by neoplastic tissue, 2. direct correlation with tumor size, 3. substances common to all tumor types ("large spectrum tumor marker") although specific tumor markers for special tumors should be available, 4. the assays must be easy and automation should be possible. At present no tumor marker satisfies all these conditions. The measurement of several tumor markers and the use of discriminant analysis may extend their diagnostic value and open the way for biochemical detection of cancer in the future.

Of 485 cases of NPC collected from the files of our institute between March 1969 and December 1974, 82 (17%) were in children and adolescents (0--19 years old). This relatively high frequency of NPC in young people was not suggested by reports from high-incidence areas (Southern China, for example) but appears to be a characteristic feature of areas of intermediate incidence (Uganda, Kenya, Sudan, Tunisia). NPC is the tumour that occurs most frequently in young people between 1 and 20 years old in Tunisia, showing a peak in those 16 years of age. The male:female sex ratio was 3:1. Advanced stages of the disease occured frequently; no clinical anomalies were noted in this age group. The 'nasopharyngeal' type of carcinoma was the histological form seen most frequently; poorly-differentiated squamous-cell carcinomas were not uncommon; and well-differentiated squamous-cell carcinomas were not seen in this series. The five-year survival rate was 32.5% for children and only 20% for adults. This can perhaps be explained by the fact that the 'nasopharyngeal' type of tumour has a better prognosis than other histological types, and, compared to adults, younger patients more frequently have distant
metastases
(37%) than local recurrences (18.5%). A
paraneoplastic syndrome
, consisting of hypertrophic pulmonary osteoarthropathy with occasional generalized lowering of pituitary function, was seen in 12 of the patients. This syndrome has been described only in children, and no cases were found in our series of adult NPC patients. Epidemiological, clinical and histological aspects suggest that NPC in young people is different from that found in adults.

Eght-four patients with renal cell carcinoma were analyzed retrospectively in order to 1) determine the effectiveness of systemic chemotherapy-hormonal and non-hormmonal, 2) identify the clinical features of renal cell carcinoma that may be important in prognosis and 3) characterize the paraneoplastic features of renal cell carcinoma.
Metastatic disease
was present at diagnosis in 57 per cent of the cases and developed within 1 year in an additional 19 per cent of the cases were paradoxically associated with a longer survival (20 months median) compared to single-organ metastasis (5 to 11 months median).
Paraneoplastic syndromes
occurred in up to 40 per cent of patients with variable survival.
Metastatic disease
was unresponsive objectively to either primary nephrectomy or to a variety of chemotherapy trials.

A case of malignant schwannoma of the sciatic nerve is described associated with hepatic dysfunction in the absence of hepatic
metastases
. An elevated serum alkaline phosphatase activity was present with an isoenzyme pattern indicating hepatic involvement. These abnormalities disappeared after extirpation of the tumour. The patient is well, with no evidence of
metastases
, over two years later. It is concluded that the abnormality of serum alkaline phosphatase was induced by the tumour, and that the liver can be involved in the
paraneoplastic syndrome
.

A 66-year-old pensioner developed distinct, erythematosquamous and keratonic lesions on the hands and feet within 2 months, and also a progressive red-bluish discoloration of the whole integument. Clinical and X-ray exploration revealed a still asymptomatic small-cell bronchial carcinoma, so that the otherwise inexplicable skin lesions made an acrokeratotic
paraneoplastic syndrome
of the Bazex type seem most likely. This very rare syndrome has hitherto been observed only in patients with carcinomas of either the bronchial or the upper digestive tract, with or without cervical and mediastinal lymph node
metastases
. We report on our third patient with Bazex-type acrokeratosis, mainly because of the uncommon distribution and severity of his otherwise typical lesions. In addition, recent reports on this syndrome in the literature are reviewed.

A patient presented with lower limb paralysis and a large malignant fibrous histiocytoma (MFH) on her back.
Metastatic disease
to the spine was excluded and the diagnosis of paraneoplastic paralysis was made. This may be the first described case of a neuromyopathic
paraneoplastic syndrome
in malignant fibrous histiocytoma. Tissue culture and electron microscopy assisted in establishing the diagnosis of the tumour. A hitherto unrecognised endocrine factor may account for the hypokalaemia which was a feature in this patient.

Seminomas are germ cell tumors that are rarely associated with hypercalcemia. In this report, four cases of seminoma with concomitant hypercalcemia are presented and another three from the literature are reviewed. All seven patients exhibited hypercalcemia with a normal serum concentration of inorganic phosphorus and no evidence of skeletal
metastases
. The peripheral venous level of parathyroid hormone (PTH) was normal in four of the five patients in whom it was measured. The serum concentration of calcitriol was elevated in the two patients in whom it was measured. After systemic chemotherapy, the serum "corrected" total calcium concentration returned to normal and remained normal; the decrease in the levels temporally paralleled the decrease in tumor volume. Both patients with elevated calcitriol levels remained eucalcemic after treatment of the malignancy, suggesting that the increased serum calcitriol level was linked to the development of hypercalcemia as this humoral agent was inappropriately elevated by patients with this syndrome. In contrast to many forms of malignancy, the development of hypercalcemia did not adversely affect the prognosis of the patients with seminoma, since all seven patients entered complete remission. Hypercalcemia appears to be heretofore unrecognized
paraneoplastic syndrome
associated with seminoma.

Paraneoplastic syndromes
are caused by factors produced by cancer cells that often act at a site distant from both the primary site and its
metastases
. These syndromes are estimated to occur in only 7% to 15% of patients with cancer and are diagnoses of exclusion. If the definition of
paraneoplastic syndrome
is broadened to include indirect effects of the tumor such as cachexia or the anemia of chronic disease, the incidence is much higher. Lung cancer, particularly small cell lung cancer, is the most common malignancy causing paraneoplastic syndromes. This review focuses on recently published literature on paraneoplastic syndromes associated with lung cancer, including humoral hypercalcemia of malignancy, autoimmune paraneoplastic neurologic syndromes, neuromuscular disorders, and cancer cachexia. It includes advances in both molecular biology and immunology, and in clinical investigation.
