Involvement of the gastrointestinal tract in systemic lupus erythematosus is well documented but small intestinal malabsorption is a rare event. We report a 27 year old woman with systemic lupus erythematosus who had malabsorption and coeliac-like changes on intestinal biopsy. This is the eighth reported case of this association the significance of which is discussed.
Primary and isolated lymphoma of the head of pancreas with secondary involvement of the lungs and obstructive jaundice, in a 31-year-old postpartum woman, is described. The histological diagnosis was diffuse histiocytic lymphoma. Chemotherapeutic treatment resulted in complete remission of the tumor. During therapy a pseudocyst of the pancreas developed and a gastrocystostomy was performed. This is the second reported case of primary pancreatic lymphoma in the English medical literature.
We studied a series of 40 rats at various stages of colorectal carcinoma, as induced by N-methyl-N-nitro-Nitrosoguanidine. Lymphokine containing supernatants were obtained simultaneously from splenic and peripheral lymphocytes, after exposure to rat colon cancer antigen in vitro. The lymphokine was found capable of performing Macrophage Migration Inhibition (MIF) when obtained from rats with: carcinoma through serosa, carcinoma of submucosa, carcinoma of the mucosa and carcinoma in situ. All control rats were free of cancer and were MIF negative. The MIF response in this study was evaluated as a marker of chemically induced colorectal carcinoma in rats in order to better understand the lymphocyte response to tumor progression from atypia to adenocarcinoma of the colon.
This case report depicts an interesting association of well-differentiated adenocarcinoma of the endometrium with benign squamous metaplastic foci confined to the fundus uteri, superficially invading the myometrium and with concomitant bilateral pelvic lymph node endometriotic adenoacanthomas. Right inguinal lymphadenopathy was detected during the first hospitalization. A lymph node biopsy from the right groin, carried out at Nahariyya, revealed apparent metastatic adenoacanthoma regarded most probably as endometrial in origin. Fractionated curettage later showed a stage Ia G1 adenocarcinoma of the endometrium with benign squamous metaplastic elements (adenoacanthoma). At Rambam Hospital, Haifa, left groin node enlargement was noted as well. The Gynecologic Oncology Unit confirmed the previous histologic findings. At exploratory laparotomy total abdominal hysterectomy and bilateral salpingo-oophorectomy, paraaortic, and bilateral pelvic lymph node sampling as well as appendectomy were performed. Bilateral groin node dissection was then carried out. Out of 37 nodes examined tumor was found in only one node, namely that of the left groin. The paper includes an extensive survey of the literature on the subject of the histopathogenesis of endometriotic foci in pelvic lymph nodes and the discussion is designed to elucidate the diagnostic problem involved in this case report.

A 49-year-old patient presented with urticaria, vomiting, diarrhea and peripheral eosinophilia. A histological diagnosis of eosinophilic gastroenteritis was made. Within 3 weeks of admission a highly papillary adenocarcinoma of the right ovary was diagnosed. The gastrointestinal symptoms and the eosinophilia disappeared after partial resection of the tumor and chemotherapy. A possible relationship between cancer, eosinophilia and eosinophilic gastroenteritis is discussed.

Ependymomas of the sacrococcygeal region almost always arise on the posterior aspect of the sacrum in the soft tissues and subcutaneous tissues of this region. The predominant histologic type of ependymoma in the sacrococcygeal area is myxopapillary. We report a case of myxopapillary ependymoma arising in the presacral area and presenting clinically as an abdominal mass. Ependymomas arising on the ventral aspect of the sacrum are exceedingly rare, and only 24 previous cases have been reported in the English literature. While dorsal myxopapillary ependymomas occasionally metastasize, there have been no reports of metastasis in the presacral tumors of this type.
The Northern Israel Cancer Center serves 1 million inhabitants. Between 1968 and 1982, 33 patients with a diagnosis of nonseminomatous tumors of the testis were referred to this center. Of these patients inguinal lymph node metastasis developed in 4, each of whom had had risk factors for such metastasis. Two patients had undergone previous orchiopexy, and 2 had extension of the tumor to the epididymis and the tunica vaginalis testis. The inguinal region should be examined and watched carefully in patients with testicular tumor, especially those at high risk for inguinal metastases. Today, disease in patients with inguinal metastasis is curable by lymph node dissection and/or combination chemotherapy.

Exposure to vinyl chloride monomer (VCM) may result in a bizarre syndrome, which is characterized by lytic changes in the distal phalanges, cutaneous stigmata of scleroderma, and Raynaud's phenomenon. Detailed case histories of two such patients are presented. Epidemiologic, pathogenetic and radiological aspects of occupational acroosteolysis are briefly reviewed. The possibility is emphasized that the condition may result not only from industrial (i.e., occupational) exposure to VCM but also from exposure in the home or neighborhood (i.e., nonoccupational).
The case of a 47-year-old white female patient has been described with malignant melanoma that started as a node on her right ankle twelve years ago and regressed spontaneously. During the last two years of her life, dissemination of the melanoma appeared in the form of subcutaneous nodes, which regressed spontaneously in successive crops. In the course of her disease there was evidence of distant metastases to the brain. Spontaneous regression seems to have been enhanced by immunotherapy, when most of the metastases had regressed, including those in the brain.

The "sudden death" of a 23-year-old Ashkenazy Jew, suffering from "familial dysautonomia" was probably caused by an arrhythmia accompanying a myocardial infarction. Such a report is unique. Diffuse coronary atherosclerosis and direct myocardial "catecholamine cardiomyopathy" seem responsible for the myocardial damage. However, diversion of the endocardial blood flow toward dpicardium and a "coronary steal" phenomenon, both the result of a sudden catecholamine discharge, could aggravate the ischemic injury.
