RESUMO

An 82-year-old woman was seen at our Dermatology Department for a plaque on the right parietal scalp that had recently increased in size, and bled. The lesion had been present for 3 months. The patient had a previous diagnosis of chronic bronchitis, noninsulin-dependent diabetes mellitus, and hypertension, but no previous history of cancer. Physical examination revealed a 7 x 10 cm plaque, composed of a central necrotic and bleeding surface, surrounded by small purple-red satellite nodules. A biopsy showed an ill-defined infiltrative intradermal mass with a pattern of hypercellular sheets of large cells alternating with areas of dilated, irregular, blood-filled channels, dissecting the collagen bundles. The endothelial cells lining these channels were plump and pleomorphic, surrounded by other spindle-shaped cells with pleomorphic and atypical nuclei. The diagnosis of angiosarcoma was made, and the patient was sent to an oncology center for further evaluation and treatment, where a computed tomography head scan was taken revealing no erosion of the skull. The patient refused surgery, so radiotherapy was proposed. One month later, she developed lymph node enlargement of the left anterior cervical nodes. A needle aspiration biopsy was consistent with sarcoma. Two weeks later, she was started on palliative radiotherapy: a programmed dose of 4500 cGy was proposed of which she only received 3000 cGy because of treatment withdrawal and loss to follow-up. During this time, she showed partial initial response, but despite treatment the disease relentlessly progressed, with hemorrhage and severe pain being the most striking features.

RESUMO

BACKGROUND: Basal cell carcinoma is the most common malignancy in Caucasians. Information about basal cell carcinoma in the Mexican population is scarce. OBJECTIVE: To determine the epidemiologic and clinical characteristics and treatment results of basal cell carcinoma located on the trunk and extremities of patients seen at the Instituto Nacional de Cancerología of Mexico. METHODS: A retrospective study was performed of patients with confirmed diagnosis of basal cell carcinoma located on the trunk and extremities seen at the Instituto Nacional de Cancerología of Mexico between 1966 and 1993. RESULTS: Ninety-one patients with basal cell carcinoma located on the trunk and extremities were found (6% of all patients with diagnosis of basal cell carcinoma). The median age was 64 years; 52% of the patients were women and 48% were men. A total of 119 basal cell carcinomas at these locations were diagnosed. The size of the skin tumor ranged from 0.3 to 22 cm (mean, 3.9 cm). Treatment results were evaluated in 62 patients (follow-up ranged from 24 to 240 months; mean, 80 months). Overall tumor control was accomplished in 95% of cases. Three patients died as a result of basal cell carcinoma. CONCLUSIONS: Basal cell carcinoma in the Mexican population is not as infrequent as previously thought, although it is less commonly located on the trunk and extremities than in Caucasians.

RESUMO

A retrospective study on the syndrome of chronic diarrhea was carried out on 50 revised clinical histories. The patients were hospitalized at the E. Rebaglati M. Hospital between April 1983 and March 1988. The purpose of the study was to evaluate the signs and symptoms of the syndrome, as well as the etiological agents and the methodology used for diagnoses. The selection criteria involved patients diagnosed as suffering from "chronic diarrhea of undetermined causes" upon entry. Seven were excluded due to incomplete study whereas 2 were diagnosed as acute infections diarrhea. Forty one patients were definite cases of chronic diarrhea and they were divided between 2 groups: the first one or Chronic Organic Diarrhea (58.53%) and the second one or Chronic Functional Diarrhea (41.46%). Out of the 41 revised clinical histories with chronic diarrhea, the following were the foundings: (1) the syndrome affects the economically active populations mainly and the length of the disease was more than 3 weeks in all the patients; (2) anemia, fever, weight loss, nightime bowel movements and bloody stools suggest organic problems whereas psychiatric disorders, daytime bowel movements, abdominal pain, disease recurrence and absence of detectable organic pathology suggest functional problems; (3) the most common cause of chronic diarrhea is the Irritable Bowel Syndrome followed by infectious diseases, with parasitosis in the first place; and (4) bearing in mind the mainly colonic affection and the predominant infectious diseases, the methodology used for their diagnosis would bring out good results.

RESUMO

Primary Sclerosing Cholangitis (PSC) is an unusual chronic, cholestatic disease of unknown etiology, more frequently seen in young adults in close relationship with Chronic Ulcerative Colitis. We report the case of a 30 year old woman, coming from the peruvian amazon with PSC associated with Sjögren Syndrome, Chronic Pancreatitis and Retroperitoneal Fibrosis, without colonic involvement. She was treated with external biliary drainage and controlled for 12 months. In this paper, clinical, biochemical, radiological, histological and therapeutic features are reviewed as well as its possible immunologie autoimmune origin.
