Pathology and Pathogenesis

Screening of mentally retarded males for macro-orchidism and the fragile X chromosome. Macroorchidism and panhypopituitarism: two different forms of presentation of FSH-secreting pituitary adenomas in adolescence. Kottler et al 14 have demonstrated that whereas the GnRH receptor gene is mainly expressed in functioning rather than in nonfunctioning gonadotroph adenomas, no mutations in its coding region have been identified, supporting the view that this mechanism is not implicated in their pathogenesis.

Moreover, on ultrasound, they appear as well-defined, unlobulated solid masses with scattered women cystic portions or as septated cystic masses with a mean size of 10—15 cm. Kelly, L.

Functioning gonadotroph adenomas FGAs are adenomas expressing and secreting biologically active gonadotropins and causing distinct clinical manifestations mainly menstrual irregularity and the ovarian hyperstimulation syndrome in premenopausal females and adolescent girls, womdn enlargement in males, and isosexual precocious puberty in children. Pigny et al 18 performed chromatofocusing analysis of FSH isoforms from a male with a FGA and found that the adenoma was characterized by more basic FSH isoforms; this was in contrast to normal pituitaries and nonclinically active gonadotroph adenomas, in which the major proportions of FSH isoforms were detected at a pH value less than 5. Their mean testicular volume exceeded the normal maximum of 25 mL 39, 37, 70, and mL, respectively. Children Isosexual precocious puberty, mass effects visual deterioration.
