Nonmelanoma skin cancer: number of cancers and their distribution in outpatients.

BACKGROUND: Nonmelanoma skin cancer (NMSC) is increasing in incidence and more are developing on the trunk and limbs. The objectives were to determine how many outpatients have more than one NMSC at the time they present for treatment and to determine the anatomical distribution of the cancers. METHODS: All outpatients with histologically confirmed NMSC visited by the authors during 1992 received a total body examination and the number and sites of NMSC were recorded. RESULTS: A total of 952 outpatients were seen. A single NMSC was present in 69.4%, two in 16%, three in 6.4%, four in 3.5%, five to nine in 4.2%, and 0.5% had ten or more. Of the 291 patients with more than one NMSC, one anatomical region was involved in 53.4%, two were involved in 38.4%, and 8.2% had three or more regions involved. CONCLUSION: Patients with NMSC required a total body examination to detect unsuspected skin cancers.

The spread of oesophageal cancer: an evaluation of clinical, barium and computed tomography assessments.

One hundred and three patients with proven oesophageal cancer were evaluated prospectively by clinical examination, upper gastro-intestinal barium studies and computed tomography (CT). The accuracy of each method in assessing the extent of disease was determined by correlation with findings at bronchoscopy (100 patients), thoracotomy (26 patients) and laparotomy (63 patients). The results indicated that CT will accurately demonstrate mass invasion of cancer into mediastinal structures. But the absence of fat-planes on CT is the least reliable indication of spread into peri-oesophageal soft tissues. Early mediastinal infiltration is best assessed by analysis of the oesophageal axis on barium swallow and the patient's symptoms. Computed tomography is not helpful in the diagnosis of mediastinal node metastases. Barium studies of the proximal stomach will accurately identify (and CT reliably exclude) local tumour extension into the stomach. CT can frequently fail to detect malignant abdominal lymphadenopathy in cachexic patients.

Zosteriform metastasis: case presentation and review of the literature.

In contrast to benign tumors, malignant tumors, by definition, are characterized by the potential of giving rise to metastases. Albeit infrequently, skin metastases do occur, and their clinical appearance varies over a wide morphologic spectrum. We present the case of a 65-year-old male with zosteriform metastasis secondary to bronchogenic adenocarcinoma. A review of cutaneous metastasis is presented with emphasis on dermatomal distribution and possible mechanisms of dissemination.

Proliferating trichilemmal tumor: report of a case and review of the literature.

The authors report a case of proliferating trichilemmal tumor and review the related literature. Although considered biologically benign, malignant proliferating trichilemmal tumor have been reported. The authors emphasize the importance of recognizing that the tumors can occur in individuals in their 20s and 30s, and that the tumors should be excised with a margin of normal tissue. Routine follow-up is recommended.

Hidroacanthoma simplex showing variation in the appearance of tumor cells in different nests.

We report a case of hidroacanthoma simplex on the inframammary area of an 86-year-old woman. The tumor cells showed considerable variation in appearance in different nests from the same lesion. By light and electron microscopy 5 types of tumor cells were identified. This tumor was thought to originate from the outer cells of the intraepidermal eccrine duct.

An intrathoracic malignant peripheral nerve sheath tumor in a dog.

A 7-year-old, neutered male Labrador Retriever presented for a persistent, productive cough and regurgitation. Radiography, ultrasonography, and computed tomography confirmed a large, smoothly marginated intrathoracic mass causing tracheal compression. The mass was removed via a thoracotomy, and a malignant peripheral nerve sheath tumor, most likely originating from the ventral spinal nerve roots, was confirmed using immunohistochemistry.

Factors influencing the short-term outcome following thoracic surgery in 98 dogs.

OBJECTIVES: To evaluate the factors influencing the short-term (<14 days) outcome of thoracic surgery in dogs. METHODS: A retrospective review of 98 dogs undergoing thoracotomy over a five-year period was undertaken. RESULTS: A pre-operative diagnosis was achieved in 69 per cent of cases. Intrathoraic neoplasia had the lowest pre-operative diagnosis rate (5.5 per cent). Mortality rates of 21 per cent were recorded and were significantly higher for intrathoracic neoplasia (50 per cent) and significantly lower for persistent ductus arteriosus (7.4 per cent) and vascular ring anomaly (0 per cent). Median sternotomy was the preferred approach for pyothorax (85 per cent) and penetrating thoracic injuries (66 per cent). Intercostal thoracotomy was the preferred approach for all other diseases. Postoperative complications occurred in 39 per cent of cases. Wound complications were more common for pyothorax (45 per cent) and following median sternotomy (71 per cent). Thoracic drains were placed in 77 per cent of cases and complications were recorded in 23 per cent. Pyothorax and chylothorax had thoracic drains maintained for significantly longer periods of time. Longer thoracic drain duration was correlated significantly with increased complication rates. CLINICAL SIGNIFICANCE: The short-term outcome following thoracic surgery is influenced by diagnosis. The thoracic approach is determined by intrathoracic disease, but may influence outcome by affecting the incidence of postoperative wound complications. The risk of thoracic drain complications increases with drain duration, which is influenced by the underlying disease. Drains should be maintained for the minimal amount of time possible.

Diagnosis of metastases from testicular germ cell tumours using fine needle aspiration cytology.

The cytological features of testicular germ cell tumours were established in smears from 15 freshly resected tumours. These features were applied to the fine needle aspiration cytology diagnosis of metastases in 27 patients referred for chemotherapy. There were 16 positive reports in 32 aspirates of which 13 were taken before chemotherapy and three in patients with residual or new masses after chemotherapy. Teratomas and typical seminomas showed certain characteristic morphological features in cytological preparations which when present in fine needle aspiration cytology material enabled tumour types to be diagnosed. Spermatocytic and anaplastic seminoma were not represented in this series. It is unlikely that these could be distinguished from malignant teratoma undifferentiated (MTU) in the fine needle aspiration cytology material. Metastases from carcinomatous areas in MTU and malignant teratoma intermediate (MTI) may not be distinguishable in fine needle aspiration cytology material from metastatic adenocarcinoma or undifferentiated carcinoma from a different primary site. Positive cytological findings are of value to the oncologist in the management of patients with metastases from testicular germ cell tumours; negative cytology does not exclude the presence of viable tumour. The sampling of small foci of viable tumour in large necrotic masses persisting after chemotherapy is a problem for radiologists, cytologists, and histopathologists. This paper does not advocate the use of fine needle aspiration cytology for the diagnosis of primary testicular tumour.
