Introduction: Dabska tumor, or papillary intra-lymphatic angioendothelioma (PILA), first described in 1969 by Dabska, is a rare vascular low grade malignancy that usually affects the skin and subcutaneous tissues of infants. Case Report: We report a case of PILA of the right tongue in a 65 years old male patient presenting as a white-bluish multinodular lesion, measuring 4x3 cm. After wide exci...

Aim: Androgens are hormones that essential for the differentiation and development of male genital organs, preserving their structural features maintaining functions. These exert effects on target tissues mainly through androgen receptors (AR). The aim this study was to determine AR immunoexpression pattern in mice. Materials Methods: A total 6 BALB/c mice were anesthetized with ether, tissues,...

Aromatase that irreversibly transforms androgens into estrogens is present in the smooth endoplasmic reticulum of nearly all cell types in the mammalian testis. In rodents, all testicular cells except for myoid cells express aromatase activity. We have demonstrated the presence of the functional aromatase (transcript or protein, and biological activity) in adult rat germ cells including pachyte...

introduction: the morphology and ultrastructure of germinal epithelum basement memberane (bm) in patients with non-obstructive azoospermia was studied by means of transmision electron microscipy. materials and methods: 10 biopsies of testis tissue from patients with non-obstructive azoospermia referred to royan institute as patients group and 5 biopsies from patients with prostatic cancer as co...

UNLABELLED Papillary intralymphatic angioendothelioma (PILA) or Dabska tumor is extremely rare, and often affects the skin and subcutaneous tissues of children. Since its first description by Dabska, only a few intraosseous cases have been described in the literature and none of them presents with multifocal osteolytic lesion of bones. We present a case of unusual multifocal intraosseous PILA i...

The present study identified the favorable conditions for isolation, enrichment and in vitro culture of highly purified, undifferentiated pig spermatogonial stem cell (SSC) lines that proliferate for long periods of time in culture. The colonies displayed morphology similar to miceSSC and were positive for markers of SSC (PGP9.5), proliferating germ cell (PigVASA), pre-meiotic germ cell (DAZL) ...
