PURPOSE Testicular teratomas in adult patients are histologically diverse tumors that frequently coexist with other germ cell tumor (GCT) components. These mixed GCTs often metastasize to retroperitoneal lymph nodes where multiple GCT elements are frequently present in the same metastatic lesion. Neither the genetic relationships among the different components in metastatic lesions nor the rela...

In this paper, we introduce a new approach to two-dimensional (2-D) processing of the one-dimensional (1-D) speech signal in the time-frequency plane. Specifically, we obtain the shortspace 2-D Fourier transform magnitude of a narrowband spectrogram of the signal and show that this 2-D transformation maps harmonically-related signal components to a concentrated entity in the new 2-D plane. We r...

A granular cell tumor (GCT) is an uncommon mesenchymal lesion that rarely occurs in the colon and the rectum. We describe the case of 51-year-old man with a 2-cm-sized rectal GCT 10 cm above the anal verge that was incidentally detected after a screening colonoscopy. Preoperative radiologic studies demonstrated a suspicious submucosal rectal mass with mesorectal fat infiltration, but without ci...

Giant cell tumor (GCT) remains as major health problem. GCT which located at the lower end of the radius tends to be more aggressive. Wide excision and reconstruction of the wrist in stage 3 of distal radius GCT lesion is an optimal modality to prevent tumor recurrence. However, dislocation often occurs as its complication. We are reporting patient with GCT of distal radius treated with wide ex...

Granular cell tumor (GCT) is a rare tumor that originates from the Schwann cells in the skin, soft tissues, and internal organs. Usually, GCTs are clinically benign, although malignant and multifocal forms are very rarely known to occur. Cases of GCT of the perianus are rare, and thus far, no study has reported synchronous GCTs of the perianus and the chest wall. We report a case of a 31-year-o...

We report here that 85% of the patients with germ cell tumors (GCTs) produce antibodies directed against Env protein of human endogenous retroviruses. Individuals that received antitumor treatment showed a decrease with time in their antibody titers. Importantly, of the rare cases of non-GCT individuals with Env-antibodies (n= 15, 0.8%), none produced antibodies directed against the transmembra...

Congenital granular cell tumor (GCT) is a relatively rare intraoral benign tumor, approximately 200 cases of which have been reported in the neonatal period worldwide. The newborn infant may have feeding problems and respiratory difficulties due to airway obstruction. This lesion may be diagnosed by prenatal ultrasonography and simple resection is mostly required. We report a case of an adult t...

We thank Dokus and Dokusova (1) for their interest in our recent article on circadian variation in the response to the glucose challenge test (GCT) in pregnancy and its implications for screening for gestational diabetes mellitus (GDM) (2). In this study, 927 pregnant women with a positive GCT underwent metabolic characterization with a 3 h 100-g oral glucose tolerance test (OGTT). Metabolic ch...

El Ministerio de Salud del Perú (MINSA) reconoce la importancia de las GCT. Por lo cual, publicó entre el 2006 y el 2008, GCT para depresión, psicosis, violencia basada en género y para problemas relacionados con el uso de sustancias psicoactivas (http://www.minsa.gob. pe/portada/est_san/saludmental.htm). Sin embargo, estas guías necesitan una revisión crítica con relación a sus recomendaciones...

Background and Objective: Histopathological evaluation of granulosa cell tumors (GCT) of the ovary may be confused morphologically with a wide variety of the tumors. Immunohistochemical staining for inhibin and calretinin can be used for better diagnosis. Although it has been suggested that inhibin can be a sensitive marker for GCT, it maybe had negative results in some cases.  In addition, cal...
