Primary adenocarcinoma of the appendix. A clinicopathological study of 11 cases.

Of eleven cases of adenocarcinoma of the appendix that were studied, five were examples of mucinous cystadenocarcinoma and four were examples of colonic-type adenocarcinoma. Two lesions were very distinctive, with thick, cord-like transformation of the appendix. The term linitis plastica carcinoma is proposed to describe this rare variant of appendiceal carcinoma. Justification for the separation of linitis plastica carcinoma from the other two types is based on morphological appearance and on outcome. Both our linitis plastica patients died of metastases within six months of surgery, whereas, in the other two groups, death was directly related to spread of the carcinoma in only two of nine patients.

Ischemic bowel disease.

The clinical, radiologic and pathologic features of 25 cases of ischemic bowel disease are presented. The majority of patients presented with the triad of abdominal pain, diarrhea and vomiting. In 13 patients the diarrhea was associated with the passage of bright red blood per rectum. There were 10 cases of infarction, 11 of enterocolitis and 4 had resulted in stricture formation. In five cases of enterocolitis the lesion was transient; symptoms improved with conservative medical management and the radiologic findings returned to normal. Barium enema examination yielded abnormal findings in the majority of the cases in which it was performed. Plain films of the abdomen, however, were not helpful. The actual mortality in this group of patients was 44%, 80% in those with infarction of the bowel and 20% in the other two groups.

Ovarian carcinoma identified by psammoma bodies in the cervicovaginal and endometrial smears.

A case of early bilateral serous papillary adenocarcinoma of the ovaries in an asymptomatic 58-year-old woman was diagnosed by the discovery of psammoma bodies in routine cervicovaginal and endometrial smears. Multiple small foci of carcinoma in-situ involving both fallopian tubes were also present. The significance of psammoma bodies in the cervicovaginal smear is discussed and the literature on the subject briefly reviewed.

Halothane hepatitis.

This report describes five cases of hepatocellular injury following halothane anesthesia. Four patients had multiple exposures to the anesthetic. Three of the five died from submassive to massive liver cell necrosis. The two survivors developed jaundice and/or dark urine following each exposure to halothane; liver biopsy in one showed centrilobular and linear areas of necrosis. Fever, anorexia, nausea, vomiting, abdominal pain and jaundice were present in all cases. In the two survivors the prothrombin time was less than 20 seconds throughout the course of the disease, whereas in the three who died the prothrombin time was more than 20 seconds from the onset. The English literature to the end of 1971 is reviewed. Approximately 600 cases of halothane-related hepatitis have been reported

Aspiration biopsy cytology of lymph nodes in malignant lymphoma.

The cytologic findings of needle aspiration biopsy of lymph nodes in malignant lymphoma are presented. In 42 of 49 cases, a correct cytologic diagnosis was rendered. There was one false-positive diagnosis. The diagnostic accuracy of needle aspiration cytology is high. It helps to select patients for further investigation and treatment, thereby avoiding unnecessary surgery in patients who present with lymphadenopathy. The technique is also useful in the staging work-up of patients with lymphoma and the diagnosis of recurrent disease during the follow-up period.

Chordoma: cytologic and immunocytochemical study of four cases.

We present the cytologic features and the immunocytochemical profile of four cases of chordoma on fine-needle aspiration biopsies. The physaliferous cells in signet-ring, pearl-like formations and the trabecular arrangement with rounded contours are distinctive. Other cell types and cellular arrangements are also described. The negative immunoreactivity of carcinoembryonic antigen (CEA) and the positive staining pattern for neuron-specific enolase (NSE), S-100 protein, epithelial membrane antigen (EMA), and keratin provide a profile that, in the appropriate clinical setting, can be useful in the differential diagnosis of chordoma from similar-appearing neoplasms in small biopsies and fine-needle aspirates.

Pseudocarcinomatous invasion in adenomas of the colon and rectum.

Of 182 polyps retrieved from 100 patients who underwent colonoscopic polypectomies, 160 were adenomas; of these, 16 contained epithelial inclusions within the stalk. The importance of recognizing this lesion lies in the fact that it mimics invasive cancer. From histologic study, criteria are proposed for differentiating the pseudocarcinomatous lesion from invasive cancer. The differentiation from colitis cystica profunda is also discussed.

Fine needle aspiration biopsy cytology of major salivary glands.

Fine needle aspiration biopsy of the major salivary glands was performed on 160 patients. In 146 patients with satisfactory samples, the cytologic diagnosis was correlated with clinical follow-up and histologic findings. There were 122 benign lesions, including 47 tumors. There were 24 malignant lesions, 10 of which were primary and 14 metastatic. The overall accuracy was 98%. The sensitivity of the technique was 87.5%. There was no false-positive diagnosis. There were three false-negative diagnoses due to sampling errors and inexperience during the initial period of the study. This study documents that needle aspiration biopsy cytology of the salivary glands is accurate, simple, rapid, inexpensive, well tolerated and harmless to the patient.
