Oral hairy leukoplakia.

Oral hairy leukoplakia occurs almost exclusively in human immunodeficiency virus (HIV)-infected patients and is predictive for the development of acquired immunodeficiency syndrome (AIDS). It presents as a white plaque with a rough surface, most commonly on the sides of the tongue. The eruption is frequently overlooked, and, because it is commonly mistaken for oral candidiasis, its true incidence is unknown.

Endoscopic Nd-YAG laser treatment of colorectal neoplasms. A four-year longitudinal study.

In order to gain a longitudinal perspective of the benefits, complications, and role of the neodymium yttrium aluminum garnet (Nd-YAG) laser in the treatment of colorectal neoplasms, we performed a review of endoscopies using the laser during a 53-month period ending in January 1989. We reviewed the records of 100 patients for details of the endoscopic procedure and demographic data. Performance status and survival were critically assessed.

Single session panendoscopy. Indications and expectations for yield.

To assess the indications and yield of single session panendoscopy (SSPE), patients who underwent colonoscopy and esophagogastroduodenoscopy (EGD) at the same time were retrospectively reviewed. Endoscopy records and patient charts of 101 patients who underwent SSPE during a 45-month period were analyzed for demography, indication, and results. Average age was 72.

Intraosseous echinococcosis: a rare manifestation of echinococcal disease.

We have presented a case of osseous echinococcosis and have reviewed the pathogenesis, pathology, diagnosis, and current treatment methods.

Crohn's disease of the appendix.

Crohn's disease limited to the appendix is uncommon. The disease may mimic acute appendicitis with fever, leukocytosis, right lower quadrant pain, and occasionally a palpable mass. When Crohn's disease affects the appendix, it typically has a longer clinical period in which the patient has symptoms than do most cases of acute appendicitis.

Squamous cell carcinoma infiltrating a pancreatic pseudocyst.

We have described a case of primary squamous cell carcinoma infiltrating a pancreatic pseudocyst, and have discussed pancreatic neoplasms arising in association with pseudocysts.

Vesicular scabies in an adult.

We describe an unusual vesicular eruption occurring secondary to scabies in an elderly patient receiving high-dose prednisone therapy.

Malignant endovascular papillary angioendothelioma (Dabska tumor). A case report and review of the literature.

Malignant endovascular papillary angioendothelioma is a rare vascular tumor of childhood that was first defined by Dabska in 1969. Microscopically, this tumor is composed of anastomosing vascular channels, some of which contain papillary projections or tuft-like structures sometimes resembling renal glomeruli. Although cases have been reported with metastases to regional lymph nodes, the long term prognosis for patients with these tumors is generally good.

Postmastectomy low-grade angiosarcoma. An unusual case clinically resembling a lymphangioma circumscriptum.

A 90-year-old white woman developed a low-grade cutaneous angiosarcoma arising on a chronically lymphedematous extremity 15 years after a radical mastectomy for breast carcinoma. This neoplasm had the clinical appearance of lymphangioma circumscriptum and was characterized by an unusually benign course with a 3-year follow-up.

Nd-YAG laser applications in surgical endoscopy: a single center comprehensive experience.

A retrospective review of endoscopic procedures using the Nd-YAG laser was carried out for patients treated between September 1984 and November 1986. Two hundred twenty two procedures were performed on 104 patients (58M:46W) during this 26 month period. The study encompasses a unique period of time in this center, as it includes the initial use of the endoscopic laser technique, the learning curves associated with its application, and finally, the time when its use became routine.

Partial gastric resection by surgical stapler.

This technique of gastric resection is easily applied and is useful for benign lesions or complicated lesions in poor risk patients. For lesions of the fundus, it may obviate an esophagogastric anastomosis. To our knowledge, the procedure has not been described in gastric resection.

Emergency treatment of menstrual disorders in a nonpregnant woman.

Women who present to the Emergency room with menstrual-related problems are a common occurrence. In this article, we will concern ourselves with common problems that the nonpregnant woman in the reproductive years may present to the emergency room, including symptoms such as vaginal bleeding, painful menses, or premenstrual syndrome. Although the treatment within the emergency room is temporizing in nature, to better understand these problems and their appropriate management, these areas will be discussed as to their etiology, treatment, and prognosis.

Coronary sinus pacer lead simulating left atrial mass.

M-mode and two-dimensional echocardiographic evaluation of a patient with rheumatic heart disease and an atrioventricular sequential pacemaker with a coronary sinus lead showed an echo-producing mass in the left atrium. A repeat study after the coronary sinus lead was replaced by a right atrial screw-in lead revealed the disappearance of the echo-producing mass.
