BACKGROUND Selective immunostaining for calretinin labels the innermost layer of the outer root sheath of normal hair follicles, which is difficult to distinguish with hematoxylin-eosin staining. OBJECTIVE The aim of this study was to determine whether immunohistochemistry for calretinin allows identification of cutaneous adnexal tumors with follicular differentiation towards cells of the out...

Cystic ovarian follicles (COF) are an important ovarian dysfunction and a major cause of reproductive failure in dairy cattle. Due to the complexity of the disorder and the heterogeneity of the clinical signs, a clear definition is lacking. A follicle becomes cystic when it fails to ovulate and persists on the ovary. Despite an abundance of literature on the subject, the exact pathogenesis of C...

We have determined the concentrations of two tumor-associated trypsinogen (TAT) isoenzymes, called TAT-1 and TAT-2, in human ovarian tumor cyst fluid using monoclonal antibody-based ¡mmunofluorometric assays specific for each isoenzyme. TAT-1 and TAT-2 are immunologically indistinguishable from the two pancreatic trypsinogen isoenzymes, cationic trypsinogen (-1) and anionic trypsinogen (-2). O...

Endometrioma is one of the most frequent pathologies in gynecologic surgery. Laparoscopic cyst excision is considered the best treatment in terms of lower recurrence and improved fertility. However, it was recently questioned whether the excision of the endometrioma could decrease the function of the operated ovary and if it could affect the subsequent fertility. Even if a consistent amount of ...

BACKGROUND The formation of functional ovarian cysts has been recognized as one of the side effects of GnRH agonist administration. The formation of cysts during IVF treatment may be of no clinical significance or may negatively influence its outcome. The objective of this study was to determine the incidence of ovarian cyst formation following GnRH agonist administration and to examine their e...

In the present report, diagnosis and treatment of a case with follicular ovarian cysts in a 5-year-old Persian queen cat is described. In response to palpation of spines, the queen cat presented herself in lordosis and danced up and down with her rear legs. Trans-abdominal ultrasonography examination showed 2 cysts  in the left ovary of the queen. Serum estrogen assay indicated elevated level o...
