Newborn intraabdominal cystic lymphatic malformations.

Cystic lymphatic malformations are rare causes of abdominal masses in the newborn. Also known as mesenteric, omental, or retroperitoneal cysts, they can present in a variety of ways including, intestinal obstruction, volvulus, nonspecific abdominal pain, intracystic hemorrhage, or as an asymptomatic abdominal mass. Abdominal ultrasound scan provides a definitive diagnosis in most suspected cases. Complete resection is possible in most patients except those with extensive retroperitoneal involvement. Recurrence is unusual when complete resection is accomplished. Because most case series with complete data suggest that these entities are lymphatic malformations, the authors suggest the more specific term, cystic lymphatic malformations, be used to describe these lesions.

Hepatobiliary dysfunction as the initial manifestation of disseminated cryptococcosis.

A case of hepatobiliary dysfunction as the initial manifestation of disseminated cryptococcosis is described. The patient was admitted with symptoms of hepatitis with cholestatic jaundice. Antibody tests for hepatitis B and C and human immunodeficiency virus were negative. The patient continued to deteriorate clinically. Eventually, the patient succumbed to hepatic failure. Autopsy disclosed systemic cryptococcosis that caused extensive necrosis of the liver. In review of the literature, only nine cases of cryptococcal infection presenting as hepatitis, cholangitis, and cholecystitis as initial manifestation were reported. Four of these patients had been subjected to exploratory laparotomy for clinical suspicion of acute abdomen. One patient developed cirrhosis as a result of cryptococcal hepatitis. Two patients succumbed to hepatic failure. Cryptococcosis is known to occur commonly in immunocompromised patients, yet only two reported cases presenting as hepatitis were associated with immunocompromised status.

Acquired cystic disease of kidney associated with renal cell carcinoma in chronic dialysis patients.

We describe 2 cases of acquired cystic disease of the kidney (ACDK) associated with renal cell carcinoma in patients treated with long-term hemodialysis. Both patients have had dialysis for five and eight years, respectively. Renal cell carcinomas of these patients are small, averaging 2 cm in diameter. They are clear cell type. Atypical epithelial hyperplasia arising from cystic areas can be seen intermingling with carcinoma. This confirms that atypical epithelial hyperplasia is a precursor of renal cell carcinoma. Although the incidence of renal cell carcinoma arising in ACDK is on the rise, the issue of how to manage patients with ACDK remained unsettled and required further study.

Gastric infarction.

We have described a patient with an acute condition of the abdomen who had infarction of the stomach and the small intestine due to atheromatous thrombus of celiac and superior mesenteric arteries. We believe this unusual simultaneous occurrence of gastric and small intestinal infarction is coincidental. The outcome of gastric infarction is frequently fatal.

Small cell carcinoma of urinary bladder. Ultrastructural study.

Two cases of small cell carcinoma of the urinary bladder are presented. On gross examination they were found to be polypoid and shared light microscopic features of oat cell carcinoma of the lung. Ultrastructurally, however, they did not reveal features of neuroendocrine cells containing neurosecretory granules. In regard to histogenesis, they appear to arise from undifferentiated cells present in the transitional epithelium.

Malignant fibrous histiocytoma of the ileum.

Malignant fibrous histiocytoma occurs most commonly in the extremities and trunk, but rarely in visceral organs. This report documents a case of malignant fibrous histiocytoma arising in the terminal ileum. Following surgical resection, there is no evidence of recurrence or metastasis in this patient after one-year follow-up studies.

Stone-like calcification of hypernephroma.

A case of stone-like calcification of renal cell carcinoma is presented. The pattern of calcification in relation to prognosis of renal cell carcinoma is discussed.

Diffuse cystitis glandularis. Associated with adenocarcinomatous change.

Although cystitis glandularis has been considered a premalignant lesion, the instance of cystitis glandularis progression to adenocarcinoma or cystitis glandularis associated with adenocarcinomatous change is rare. This article includes 4 cases of neurogenic bladder with urinary diversion for different periods of time. In the first case with ureterocutaneostomy for twenty-five years diffuse cystitis glandularis with multifocal adneocarcinomatous change developed. The second case with suprapubic cystostomy for twenty-two years had diffuse cystitis glandularis of gastrointestinal type without evidence of malignancy. The other 2 cases with suprapubic cystostomy for merely ten years showed only mild to moderate cystitis glandularis and chronic cystitis with squamous metaplasia, respectively. The extent of cystitis glandularis appeared to correlate with the duration of urinary stasis. Ureterocutaneostomy rendered constant infection of the urinary bladder of the first case because of inadequate drainage. Thus, we assume that the intensity of the infection with a toxic product and virulence of organism may be responsible for the development of adenocarcinoma in this patient. Cystitis glandularis, especially diffuse type, can undergo malignant degeneration under constant irritation, but it is a long-term process.

Cholesterol granuloma of right testis.

A case of cholesterol granuloma of the testis is presented. This lesion might be caused by trauma and inflammation. The difference between cholesterol granuloma and lipogranuloma of the external genitalia is emphasized.

Budd-Chiari syndrome caused by undifferentiated small round cell tumor of the liver in an adult.

An undifferentiated small round cell tumor of the liver in a 60 year old black male is described. Although the light microscopic findings in this tumor were strongly suggestive of embryonal rhabdomyosarcoma, the ultrastructural study disclosed no myofibrils or other specific characteristics. Thus, we classify this tumor as an embryonic tumor or primitive mesenchymal tumor of the liver.

Malacoplakia of the vagina.

Malacoplakia of the vagina was incidentally discovered in a 47-year-old white woman with a history of chronic active hepatitis and steroid hormone therapy. The relation between malacoplakia, liver disease, and steroid therapy is discussed.

Coexisting malignant lymphoma and adenocarcinoma of the stomach.

The fourth case of malignant lymphoma coexisting with an adenocarcinoma in the stomach is presented. Although an increased incidence of systemic malignant lymphoma in association with gastrointestinal tumors has recently been emphasized, primary gastric lymphoma and adenocarcinoma coexisting in the same stomach is still rare.

Basal cell adenoma of prostate.

A case of basal cell adenoma originating in the prostate is presented. This lesion might develop from proliferation of basal epithelial cells of the prostate gland under unknown mechanism.

Cushing's syndrome and functioning adrenal black adenoma.

A case of functioning adrenal black adenoma with Cushing's syndrome is briefly presented. This is the fourth reported case of this particular functioning tumor. The other three cases were also associated with Cushing's syndrome. The angiographic feature of adrenal venography in our case is identical to ordinary adrenal neoplasm and is the first documented roentgenologic study.
