Candidal infection of benign gastric ulcers in aged patients.

In seven elderly patients with benign gastric ulcer, numerous spores and mycelia of Candida were found in the inflammatory exudate and in the base of the ulcer. All patients were treated with cimetidine and antacids. In five patients the ulcer failed to heal. Cimetidine was replaced with mycostatin and after four weeks of treatment, the ulcers healed completely in four patients. It is assumed that in the elderly, due to the weakening of the host defense mechanisms, Candida may invade the base of the ulcer and disturb the normal process of healing.

Diagonal ear lobe crease and coronary risk factors.

The prevalence of ear lobe crease (ELC) was determined in 421 patients with myocardial infarction (MI) and in 421 controls. A higher prevalence (p less than 0.05) of ELC was found in MI patients (77 percent) in comparison to controls (40 percent), regardless of age. In addition, a higher prevalence was found in patients in whom MI was combined with diabetic retinopathy or hypertension, and in Ashkenazi Jews compared to non-Ashkenazi Jews. Ear lobe biopsies in 12 subjects revealed tears of the elastic fibers in all subjects with ELC, and prearteriole wall thickening in subjects with MI and/or ELC, but not in the 2 subjects with neither MI nor ELC. The early appearance of ELC may imply the existence of coronary heart disease with or without coronary risk factors.

Spontaneous rupture of renal and ureteral tumors presenting as acute abdominal condition.

We report on 3 patients who presented with an acute onset of abdominal pain, a palpable abdominal mass and a rapid decrease in hemoglobin. In 2 patients a spontaneously ruptured hypernephroma was found and the other patient had a squamous cell carcinoma of the ureter with bleeding into the tumor. Although in all 3 cases the tumors were at an advanced stage of development, the patients had been entirely free of urological symptoms until shortly before hospitalization. The importance of considering the possibility of spontaneous rupture of such a tumor in the evaluation of cases of an acute abdomen is stressed.

Oestrogen-induced renal carcinoma.

Oestrogen may be implicated as an aetiological factor in the development of some renal carcinomas in man. The development of a renal carcinoma in 2 patients who had been treated with low-dose oestrogen for periods of 3 and 3 1/2 years because of prostatic carcinoma is described. It is suggested that patients receiving prolonged oestrogen therapy should be evaluated for the presence of a renal carcinoma at regular intervals.

Multiple pulmonary hamartomas; a case report and review of the literature.

Bilateral multiple hamartomas were found in a woman suspected of having metastatic malignancy of the lung. As extensive investigation for the primary tumour was unrevealing, a left exploratory thoracotomy and histological examination established the diagnosis. In view of the benign character of the tumours, local excision alone was performed. No surgical intervention was performed on the right side. Repeat chest films 12 months after surgery did not show the appearance of new lesions in the left lung or any increase in the size of the nodules in the right lung. This is the 12th case so far reported. The clinical characteristics and surgical management of these tumours are discussed.

Clinicopathological study of a patient with procainamide-induced systemic lupus erythematosus.

A patient who developed a multisystem involvement of systemic lupus erythematosus (SLE) after 9 years of procainamide therapy, during which time he ingested enormous amounts of the drug, is described. The patient first suffered from recurrent episodes of pleuritis and arthritis, after which he developed a characteristic SLE nephritis associated with a high level of antinative DNA antibodies and a low level of complement. He finally died from a complication of a nonbacterial endocarditis. Autopsy showed polyserositis and typical deposits of electron-dense material on the glomerular basement membrane, and confirmed the clinical diagnosis of Libman-Sacks endocarditis. The possibility that procainamide-induced SLE might have all the clinical, immunological, and pathological features of spontaneous SLE, especially in patients exposed to large doses of the drug for many years, is discussed.

Clear cell carcinoma of the thyroid gland.

Clear cell carcinoma is a rare variant of thyroid cancer, histologically related to the well-differentiated thyroid malignancies. The purpose of this paper is to discuss data collected from the English literature and to present three additional cases. In two of the three cases presented, thyroglobulin levels were extremely high after thyroid ablation. Both cases presented metastasis to lung and bone with significant I131 uptake. It seems that, when compared to the well-differentiated carcinomas of the thyroid gland, clear cell carcinoma has a more aggressive clinical course. Initial radical surgery is the treatment of choice for this kind of neoplasm and I131 should always be considered for the treatment of its metastasis.

Carcinoma of the prostate metastatic to the maxillary antrum.

Metastatic carcinoma of the maxillary antrum is an extreme rarity. Until 1980, less than 100 cases with distant primaries metastatic to the entire sinonasal tract had been reported. In a review of these cases, we found no mention of primary prostate cancer metastatic to the antrum. The purpose of this paper is to document the first case of this entity.
