The granular cell tumor (GCT) is a rare, benign tumor that most commonly occurs in the oral cavity, particularly in the anterior part of the tongue. In this study the experience with 16 patients with a GCT observed in a single Institution will be discussed. Although no radicality has been obtained in most cases, recurrences are rare. In one patient, a recurrence was noted four years after excis...

Background: Many patients are not referred to centers specializing in the treatment of peritoneal malignancies. This survey evaluates Canadian physician attitudes toward the role of cytoreduction in treating colorectal carcinomatosis. Methods: A discrete-choice questionnaire containing a hypothetical scenario surveyed physician preferences for the management of colorectal carcinomatosis. Result...

BACKGROUND Although sarcoidosis as well as lung cancer are frequently encountered common diseases, their metachronous or synchronous occurrence in the same patient is very rare. METHODS The charts of lung cancer patients, diagnosed between 1980 and 2007 in our hospital, were reviewed. RESULTS We found 3 cases with sarcoidosis and lung cancer. The first case had lung cancer 16 years after th...

Apparently normal mucosae adjacent to colon adenocarcinomas were studied by cutting strips of mucosa from the entire length of 120 surgical specimens (94 located on the distal colon and 26 on the proximal colon). These mucosae were coiled into "Swiss rolls." Their mucus alterations were mapped by immunoperoxidase using antibodies against M1 antigens, oncofetal markers associated with precancero...

The presentation of synchronous primary tumours is rare and presents a difficult diagnostic and therapeutic challenge to primary care clinicians and hospital specialists. Increased life expectancy, improved radiological and biochemical investigation and more rigorous pre- and postoperative evaluation will lead to an increasing clinical trend for both metachronous and synchronous primary neoplas...

Gastrointestinal stromal tumours (GIST) are rare mesenchymal neoplasms in the gastrointestinal tract. The metachronous existence of GIST and gastric adenocarcinoma, though are tumours of distinct histotype, and very rare, have been reported in medical case reports in recent years. We report a case of a 74 year old man who initially presented with moderately differentiated adenocarcinoma of the ...

Osteosarcoma of the jaw (JOS) is a rare phenomenon constituting 5% to 13% of all cases of osteosarcoma (OS). JOS has histological features similar to OS, but the biological behavior is different. The chief complaint of patients with long bone OS is pain, whereas patients with JOS usually have painless swelling as the first sign. OS may affect multiple sites. Multifocal or multicentric osteosarc...

INTRODUCTION adrenal gland, parotid gland, pharynx, eye and bladder are rare localizations of metastases of renal cell carcinoma (RCC). We report a case of metachronous RCC metastases to the bladder in a patient with a medical history of transitional cell carcinoma (TCC) of the bladder. MATERIALS AND METHODS a case study and review of the relevant literature are presented. RESULTS during a ...

Reconstruction of large, complex defects of the abdominal wall after resection of malignant tumors can be challenging. The transfer of an anterolateral thigh (ALT) flap is a feasible and effective option. However, no report has been published on the use of ALT flap after metachronous colonic tumor resection so far. We present an original case of resection of metachronous carcinoma of rectum wit...

We here report on a case of metachronous multicentric carcinomas of the biliary tract treated 3 times with curative surgery over 23 years. A 28-year-old woman underwent cholecystectomy because of papillary carcinoma of the gallbladder. After 17 years, 3 carcinomas developed in the biliary tract: intrahepatic cholangiocarcinoma of the left liver, common bile duct carcinoma, and remnant cystic du...
