Insights
Congenital syphilis is a persistent challenge. A 2-month-old infant presented with classic symptoms, including skin lesions and bone changes, confirming prenatal syphilis transmission.
Area of Science:
- Pediatrics
- Infectious Diseases
- Dermatology
Background:
- Syphilis in pregnancy remains a global health concern, despite available diagnostics and treatments.
- Early diagnosis and management are crucial to prevent congenital syphilis and its sequelae.
Observation:
- A 2-month-old infant presented with rhinorrhea, papulosquamous lesions on palms and soles, and perianal erosions.
- Physical examination revealed characteristic cutaneous and perianal lesions.
- Radiographs showed early periosteal changes in the humerus and tibia.
Findings:
- The infant's Serum Rapid Plasma Reagin (S.RPR) test was positive at 1:64 dilution.
- The mother's S.RPR test was positive at 1:8 dilution.
- These results confirmed the diagnosis of early congenital syphilis.
Implications:
- This case highlights the importance of vigilant screening for syphilis in pregnant women.
- Prompt diagnosis and treatment are essential to prevent severe outcomes in infants.
- Continued public health efforts are needed to combat syphilis transmission during pregnancy.
Abstract:
Syphilis in pregnancy still remains a challenge despite the availability of adequate diagnostic tests for serological screening and penicillin therapy. We report a case of 2 month old female infant who presented with runny nose, papulosquamous lesions over both palms and soles and perianal erosions since 1 month after birth. Cutaneous examination revealed moist eroded areas in the perianal region and fine scaly lesions over palms and soles. Radiograph of both upper limbs and limbs revealed early periosteal changes in lower end of humerus and lower end of tibia. Diagnosis of early pre-natal syphilis was confirmed by Child's Serum Rapid Plasma Reagin Antibody test [S.RPR] being positive with 1:64 dilution while that of mother was 1:8.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
