granular cell tumor (gct) was first described by abrikossoff in 1926. gct is a rarely seen soft tissue tumor and is generally benign. while the tumor can be seen in all parts of the body it is generally located on the head and neck region, and especially on the tongue. gct is rarely seen in the anal-perianal region. in accordance with literature this case was reported because it was thought to ...

the congenital gingival granular cell tumor (cgct), also as known as congenital epulis, is an unusual benign oral mucosal lesion in newborns. a two-day-old female patient was admitted to the department of pediatric dentistry at gulhane medical academy, ankara, turkey with her family, and an intraoral examination showed a cgct located in the buccal region of the maxillary right first primary mol...

Introduction: Granular cell tumors (GCTs) are rare and mostly benign soft tissue tumors. Though they have been reported in all parts of body, they are generally located in the head and neck region, especially on the tongue. Some malign forms exist, but these have been rarely reported. Granular cell tumors have a neural origin and, in immunohistochemical evaluations, they express S-100 and neuro...

Refractile eosinophilic granular cells, when present in abundance in a glioma, may trigger a diagnosis of the relatively familiar and inherently malignant 'granular cell astrocytoma'. The following two cases remind us that refractile eosinophilic granular cells are not unique to granular cell astrocytoma but can also dominate the histology of oligodendroglioma confirmed by 1p19q loss, and the i...

perivascular epithelioid cell tumor (pecoma) is composed of hmb45+ epithelioid cells with clear to granular cytoplasm and perivascular distribution. we describe a uterine pecoma in a 33 years old woman where tumor cells were positive for hmb45 but negative for epithelial markers and negative or positive for smooth muscles markers.

The aim of the present study was to determine various types of hemocytes, total and differential hemocyte count and to show some indices of phagocytosis, including percent phagocytosis and phagocytic index in Indian white shrimp, Fenneropenaeus indicus in Iranian shrimp farms. The hemolymph was extracted from the shrimps and mixed with anticoagulant. It then stained and Yeast was added as forei...

Aims. The aim is to present a case of rare giant granular cell ameloblastoma and to review the pertinent literature highlighting the molecular aspects of its pathogenesis by analyzing the expression of CD-68, Bcl-2, and β -catenin. Methods. H and E stained sections showed large odontogenic islands showing peripheral ameloblast-like cells and central stellate reticulum-like cells with extensive ...

Granular cell tumor is an uncommon benign hamartomatous lesion occurring in almost any part of the body. Granular cell lesions may be found in other diverse sites, such as the jaw, skin, gastrointestinal tract and respiratory tract. The tongue and buccal mucosa are common intraoral sites. The histogenesis of the lesion remains unknown. In this paper, we report the occurrence of an oral granular...
