BACKGROUND Intraventricular tumors represent a diagnostic problem, due to a wide range of differential diagnosis, with an important variability of tumoral histological types in adult and pediatric population. Patient, METHODS AND RESULTS Our case is represented by a patient, aged 48 years, without any history of significant personal pathology, accusing nausea, vomiting, and intensive headache...

INTRODUCTION Although few cases of squamous cell carcinoma (SCC) with clear cells have been published, we believe that these cells are often present in SCC. MATERIAL AND METHODS We studied 249 SCCs, analyzing a number of clinical and histological variables. Various immunohistochemical techniques (immunoperoxidase method) were used to determine whether adnexal differentiation was present. RE...

The clinical and pathological findings in three patients with clear cell carcinoma of the larynx are described. This type of neoplasm in the larynx is extremely rare. The aggressiveness of the tumour and its high biological malignancy are stressed.

PURPOSE Glycogen rich clear cell carcinoma (GRCC) of the breast is a rare subtype of invasive ductal carcinoma and involves a poor prognosis. In the literature, less than 150 cases have been reported. Many researchers have attempted to characterize GRCC according to electron microscope, flow cytometry, or clinical data. However, an organized study of the immunophenotype of GRCC has yet to be re...

clear cell renal cancer (ccrc) is a tumor with great metastatic potential, but solitary metastases, especially in the thyroid gland, are uncommon and difficult to diagnose1. A patient with a solitary thyroid metastasis from ccrc is reported, and the literature is reviewed. the patient was a 66-year-old male patient with a history of high blood pressure, chronic renal failure, hyperuricemia, cur...

Renal cell carcinoma is the most common renal tumor in adults. Clear cell carcinoma represents 85% of all histological subtypes. In February 2012 a 72-year-old woman came to our department due to the appearance of massive hemoptysis and pharyngodinia. Previously, this patient was diagnosed with a renal cell carcinoma treated with left nephrectomy. We observed an exophytic, grayish, and ulcerate...

background: esophageal carcinoma is one of the most lethal gastrointestinal (gi) malignant tumors worldwide.  the disease is known to have a high incidence in northern iran; however, its condition in the south is not much clear.   objective: in this retrospective study we investigated the epidemiology and time trends of esophageal carcinoma in fars province, south of iran.   methods : in a retr...

Clear cell carcinoma of the thymus is a rare tumor. Few cases of clear-cell carcinoma of thymus have been documented (Truong et al., 1990 and Wolfe III et al., 1983). All these cases were diagnosed by histopathological examination of the tissue. Diagnosis of thymic clear cell carcinoma on cytology is extremely challenging. Here we report the first case of thymic clear cell carcinoma diagnosed b...

Mucoepidermoid carcinoma is a rare conjunctival neoplasm that is a common malignancy in the salivary glands. In the conjunctiva it often mimics squamous cell carcinoma. Histologically the tumors are believed to arise from pluripotential basal cells and, possibly, mucussecreting elements, and therefore are composed of mucus-secreting cells intermixed with epidermoid cells. The clear cell variant...
