Objectives: We aimed to analyze the utility of fetal autopsy in terms of its contribution to establishing a definitive diagnosis and its impact on genetic counseling.
Subjects And Methods: Detailed fetal autopsy was carried out in fetuses referred for examination. Clinical utility of fetal autopsy and its impact on counseling were measured by adapting previously published parameters.
Results: We performed autopsy in 230 fetuses. There were 106 cases with single system and 92 cases with multisystem involvement. We confirmed prenatal findings in 23% of cases and observed additional findings in 37% of cases. In 23% of cases, autopsy findings differed enough to change the diagnosis. However, in 17% of fetuses, no cause of fetal loss was determined. Risk of recurrence became clear in 30.3% of the fetuses, and risk remained the same, but the diagnosis was different in 4.8% of cases after autopsy. Hence, autopsy led to refinement of the risk of recurrence in 36% of cases. Autopsy aided prenatal counseling of couples in 77% of cases by either confirming the prenatal findings (35%) or providing new information/ruling out a diagnosis (42%).
Conclusion: The present study quantifies the utility of fetal autopsy in reproductive genetic counseling in a large cohort.

Objectives: Congenital thoracic masses (CTMs) are suspected in presence of solid or cystic thoracic lesions at ultrasound. The common typical fetal CTMs encompass: hyperechogenic lung lesions such as congenital pulmonary airway malformation (CPAM), broncopulmonary sequestration (PS) and congenital high airway obstruction syndrome (CHAOS); less common solid thoracic masses are mediastinal/pericardial tumors as rhabdomyoma and teratoma. The aim of our study is to gather the available evidence on cases of atypical CTMs of difficult classification, for which the diagnosis remains often uncertain.

Introduction: Agrin, encoded by AGRN, plays a vital role in the acetylcholine receptor clustering pathway, and any defects in this pathway are known to cause congenital myasthenic syndrome (CMS) 8 in early childhood with variable fatigable muscle weakness. The most severe or lethal form of CMS manifests as a fetal akinesia deformation sequence (FADS). To date, only one family has been reported with an association of null variants in AGRN and a lethal FADS.

Background: ALG8-congenital disorder of glycosylation (ALG8-CDG) is a rare inherited metabolic disorder leading to severe multisystem manifestations, with no reported prenatal patients to date.
Methods: We describe two fetuses from a single family with ALG8-CDG presenting with prenatal hydrops, undergoing comprehensive prenatal ultrasound, umbilical cord blood biochemistry, autopsy, placental pathology, and genetic testing.
Results: Prenatal ultrasound revealed fetal hydrops, skeletal anomalies, cardiac developmental abnormalities, cataracts, echogenic kidneys and bowel, oligohydramnios, choroid plexus cysts, and intrauterine growth restriction.

The current case report presents the postmortem examination findings of a 17-week-old female fetus displaying thanatophoric dysplasia type 1 (TD-1) due to a known fibroblast growth factor receptor 3 (FGFR3) gene mutation. Gross and X-ray examination revealed significant abnormalities, including skeletal malformations with prominent TD-1 femur curvature. Microscopical evaluation indicated inadequate histological growth for the gestational age, with specific organ immaturity noted in multiple hematoxylin and eosin sections from internal organs, bone from epiphyses and diaphyses levels.

Congenital melanocytic nevus (CMN) syndrome is a rare, non-familial neural ectodermal dysplasia characterized by CMN combined with extracutaneous abnormalities, predominantly involving the central nervous system (CNS). The pathogenesis of CMN syndrome is thought to result from early post-zygotic somatic mutations. CNS melanosis frequently affects the anterior temporal lobes, brainstem, cerebellum, and cerebral cortex.
