The current case report presents a male baby, second born to nonconsanguineous parents at 38 weeks of gestation by lower segment cesarean section, with engorged blood vessels and distinctive patterns of discoloration and dilation of blood vessels on the left leg. A Doppler of the femoral artery and vein showed normal triphasic flow and waveforms without any evidence of significant luminal stenosis. There was also a lower limb length discrepancy of 1.5 cm. Genetic testing using fluorometric enzyme immunoassay screening revealed a negative screening report. Otologic screening using distortion product otoacoustic emissions revealed normal functioning of outer hair cells in both ears. The case was diagnosed as cutis marmorata telangiectatica congenita (CMTC), after ruling out genetic diseases. It was not associated with any other significant health problems. The diagnosis of CMTC was based on the appearance of the skin at birth, which became more noticeable shortly after two days. In this case, no specific treatment was warranted and the condition improved with time.

A 14-month-old female child was brought to us by her parents with the complaint of progressive shortening of her right lower limb since birth. Born to non-consanguineous parents from a poor socioeconomic background, her birth and antenatal history were uneventful. Physical examination revealed no facial dysmorphism; however, her right thigh was short and bulky, and there were restrictions in hip, knee, and ankle movements. The pediatric evaluation showed normal growth and development. X-rays confirmed proximal femoral focal deficiency (PFFD) of the right lower limb. After extensive parental counseling regarding the condition, potential interventions, and outcomes, the parents opted for prosthetic management due to concerns about surgical costs, risks, and cosmetic outcomes. A custom-made extension prosthesis was prepared for the limb and was fit. At a follow-up of one year, the child exhibited a normal gait pattern with stable hip, knee, and ankle motion, and the parents expressed satisfaction with the prosthetic management, preferring it over surgical intervention for the time being.

This report aims to investigate the association between 47,XXX and fetal hydrops by examining a clinical case and performing a comprehensive review of the relevant literature. A 34-year-old Japanese woman, gravida 2, para 1, was diagnosed with fetal hydrops at 27 weeks\' gestation. Prenatal testing revealed a 47,XXX karyotype. Interventions included thoracocentesis and a thoracoamniotic shunt. A cesarean delivery was performed at 34 weeks and the female neonate initially had respiratory challenges. After 69 days in the neonatal intensive care unit, the infant was discharged in stable condition, and the 47,XXX karyotype was confirmed. This case may add evidence suggesting an association between 47,XXX and fetal hydrops. Chromosomal abnormalities are causes of fetal hydrops, but its association with 47,XXX remains unclear. Providing comprehensive information on this condition to couples is crucial, and considering the inclusion of fetal hydrops in the list of associated conditions might be advisable.

BACKGROUND: Polydactyly is a congenital abnormality characterized by the presence of additional fingers on one or more extremities. In Colombia, polydactyly accounted for 17% of musculoskeletal congenital abnormalities in 2021, with a prevalence of 6.03 per 10,000 live births. The purpose of this study was to determine the prevalence of polydactyly and identify associated risk factors in Bogotá and Cali, Colombia, from 2002 to 2020.
METHODS: A retrospective case-control study design was employed, analyzing data from birth defect reports provided by the Program for the Prevention and Follow-up of Congenital Defects and Orphan Diseases surveillance system. Cases included live births or stillbirths with polydactyly, while controls consisted of infants without congenital abnormality, matched in terms of birth date and hospital. Prevalence of polydactyly was calculated and risk factors were assessed through odds ratios obtained by logistic regression models, considering a 95% confidence interval.
RESULTS: Among the 558,255 births included in the study, 848 cases of polydactyly were identified, resulting in a prevalence rate of 15.19 per 10,000 live births. Risk factors associated with polydactyly included male newborn sex, pregestational diabetes, and a family history of malformation among first-degree relatives.
CONCLUSIONS: These findings highlight the importance a surveillance system aimed to characterize populations with congenital abnormalities, providing a better option for analyzing risk factors, help improving prevention, diagnosis, notification, and optimal treatment in patients.

Abomasal ulcers, an economic concern for all calf-raising farms, are usually silent until perforation occurs, at which time management is complicated and often unrewarding. This case study describes perforating ulcer in a 3-day-old Brahman heifer, occurring secondary to a congenital narrowing of the pylorus and proximal duodenum and leading to marked abomasal distention, leakage, and eventual peritonitis and sepsis.

UNASSIGNED: Situs inversus totalis is a rare congenital abnormality characterized by a mirror-image transposition of both the abdominal and the thoracic organs. Vertebral anomalies causing congenital scoliosis are classified on the basis of failures of formation, segmentation, or both. The hallmark of surgical treatment is early intervention before the development of large curvatures. The surgical treatment of a congenital deformity mandates the use of neurological monitoring to minimize the risk of perioperative neurological deficit.
METHODS: We present a 21-year-old patient who was admitted for her scoliosis deformity correction. Complaints of back pain when standing for a long time and carrying heavy loads for too long. Her systemic examination revealed the apex cardiac beat on the right side, liver dullness on the left side, and rib hump deformity.
UNASSIGNED: Congenital scoliosis is the most frequent congenital deformity of the spine. Congenital curvatures are due to anomalous development of the vertebrae (failure of formation and/or segmentation). Congenital scoliosis is believed to be related to an insult to the fetus during spine embryological development and associated malformations. In our case, the X-ray showed that the cardiac apex, spleen, stomach, and aorta were present on the right side, and the larger liver lobe and inferior vena cava were noted on the left side. Thus, the image manifestations supported the diagnosis of situs inversus totalis.
CONCLUSIONS: Corrective surgery with osteotomy could be a safe and effective for the treatment of scoliosis associated with situs inversus totalis.

A 59-year-old male was incidentally diagnosed with a left atrial mitral valve chordae involving the junction of the A1 and A2 mitral valve leaflets and resulting in moderate mitral regurgitation. The recognition of this extremely rare congenital malformation prevented over diagnosis and overtreatment.

Symbrachydactyly is a complex and rare congenital hand deformity characterized by missing or underdeveloped fingers and rudimentary digit nubbins. This case report focuses on a newborn female with type 3A symbrachydactyly, highlighting the unique clinical presentation, diagnostic assessment, and initial management approach. The rarity of this condition underscores the need for sharing cases to enhance understanding and treatment strategies. Various classification systems exist, contributing to the challenge of accurately categorizing symbrachydactyly. Surgical interventions play a crucial role in restoring hand function and appearance, with treatment choices tailored to individual evaluation and goals. Early surgical intervention is often necessary to improve outcomes, and nonvascularized toe phalangeal transfers have shown promising results. Further research is required to uncover the underlying cause and pathogenesis of symbrachydactyly, enabling more targeted and effective treatment approaches. This case report contributes to the existing knowledge and management of this uncommon congenital anomaly, emphasizing the importance of sharing and studying such cases for improved patient care.

Unilateral lung agenesis is a rare congenital abnormality that typically presents with respiratory distress after birth. Prognostic factors include the side of the lung affected along with the presence or absence of other congenital abnormalities. Prenatal imaging can make the diagnosis that can assist the healthcare team in preparing to care for the neonate, as well as set expectations for the family. In this case series, we describe three cases of unilateral lung agenesis, two infants with right lung agenesis, and one with the left. We describe their presentation, provide a brief clinical course, and discuss outcomes.

Pulmonary sequestration is a rare congenital bronchopulmonary malformation with an estimated incidence of less than 6%. It is described as the abnormal formation of nonfunctional lung tissue that receives its blood supply from systemic circulation rather than the bronchial tree. Most are unilateral, while a miniscule proportion is bilateral. Delayed diagnosis can result in recurrent pneumonia, failure to thrive, regular hospital visits, morbidity and even fatality. Thus, it is important to raise awareness of this condition. Herein, we present a case of a 42-year-old patient with bilateral pulmonary sequestration (BPS) on a triple rule out CT angiography (TRO-CTA).
