Introduction: Incontinentia pigmenti (IP) is a rare genodermatosis. It classically has manifestations of linear vesicular lesions, evolving into verrucous lesions within few weeks, followed by a peculiar swirled pigmentation lasting for many years. In addition, IP can affect other ectodermal tissues such as the teeth, eyes, bones, and the central nervous system. Case report: We report a case of IP in a newborn female baby who presented to us with verrucous lesions at birth and on examination was found to have congenital heart disease (atrial septal defect, with pulmonary hypertension, tricuspid regurgitation, and predominant right to left shunt). Discussion: We wish to draw attention to the association of IP with congenital heart disease.

| Introduction|| |
Incontinentia Pigmenti (IP) (Bloch-Sulzberger syndrome) is a rare hereditary syndrome inherited by X-linked dominant pattern. It occurs in approximately 1:40,000 – 1:50,000 births. It primarily affects female infants, and is lethal in males.
The mutation of NF-kappa-B essential modulator, also known as IKK-γ/inhibitor of nuclear factor kappa-B kinase subunit gamma (IKBKG) gene which is located on chromosome Xq28, is believed to play a role in the pathogenesis of this disease. The IKBKG gene is involved in regulation of cell division and programmed cell death. Approximately 60% of cases are found to be sporadic.
Skin involvement occurs in all patients, manifesting as vesicular, verrucous, and peculiar swirled, pigmented cutaneous lesions sequentially.
In addition, other ectodermal tissues may also be affected, such as central nervous system (CNS), eyes, hair, nails, and teeth – presenting as developmental defects of eyes (cataract, optic atrophy, strabismus, and retrolental fibroplasia), teeth (delayed dentition, partial anodontia, cone- or peg-shaped teeth), skeletal system (skull and palatal defects) and CNS (epilepsy, microcephaly, mental retardation, and slow motor development), and cardiac abnormalities (pulmonary arterial hypertension, atrial septal defect [ASD], tricuspid regurgitation [TR]).
| Case Report|| |
A newborn child born of second-degree consanguineous marriage to an elderly mother with a full-term normal vaginal delivery with no prenatal and postnatal complications presented to us few hours after birth with generalized verrucous skin lesions distributed mainly over the trunk [Figure 1] and [Figure 2] and extremities [Figure 3] in a blaschkoid pattern. Lesions involved the scalp, sparing the face. The nails were found to be dystrophic [Figure 4].
No similar skin lesions were noted among the family members. There was no history of previous abortions in the mother.
Routine blood parameters were normal; no eosinophilia was noted in our case. Ophthalmological evaluation (fundoscopy) was normal at birth and at 1 year of age. Two-dimensional echo of the heart revealed congenital heart disease (ASD, secundum type – 3.95 mm) [Figure 5] with pulmonary hypertension and tricuspid regurgitation, with predominant to right-to-left shunt [Figure 6]. MRI of the brain was normal. No skeletal or dental abnormalities were noted in our case at one year follow-up. X-ray (whole body) was found to be normal, but the possibility of developing at a later age cannot be ruled out abnormalities.

There were no cutaneous signs suggestive of congenital heart disease in the baby. The baby showed signs of respiratory distress like rapid and shallow breathing and respiratory rate of 68 breaths/min, heart rate of 180 beats/min. on examination by neonatologist loud second heart sound (S2) and mid diastolic murmur were also noted. She was managed in neonatal intensive care unit and discharged after two weeks once the respiratory distress subsided.
Histopathology of the skin lesions showed diffuse hyperkeratosis, papillomatosis, and acanthosis, consistent with verrucous stage of IP [Figure 7].

The lesions started to pigment and flatten in a span of a week, suggestive of evolution of the lesions to hyperpigmented stage of IP from verrucous stage [Figure 8].

After a year, the baby showed complete involution of verrucous lesions and progression to hyperpigmentary [Figure 9] and hypopigmentary stage [Figure 10].

Genetic studies for establishing the confirmative diagnosis could not be done in our case due to nonavailability of the facilities.
| Discussion|| |
Cutaneous findings are indicative of the disease and usually appear in chronological sequence, characterized by a progression through four distinct stages.
- Stage 1 – Inflammatory or vesicular stage is characterized by the development of papules and vesicles on an erythematous base and distributed along the Lines of Blaschko More Details.
In most patients (>90%), lesions are present at birth or develop during the first 2 weeks of life.
- Stage 2 – Verrucous stage is characterized by plaques and warty papules linearly arranged over an erythematous base, also following the lines of Blaschko. It may rarely be present at birth as seen in our case; however, in 70%–80% of patients, it evolves after the first stage in few weeks
- Stage 3 – Hyperpigmented stage is defined by the development of linear or whorled lesions, with a brownish pigmentation
- Stage 4 – Atrophic or hypopigmented stage is characterized by areas of hypopigmentation, atrophy, and absence of hair, most frequently observed on the lower extremities. These lesions usually develop during adolescence, persist into adulthood, and may be permanent.
Diagnostic criteria for incontinentia pigmenti in the absence of familial history (Landy and Donnai, 1993).
- Typical neonatal vesicular rash (erythema, vesicles, and eosinophilia)
- Typical hyperpigmentation (especially on the trunk, following Blaschko lines, disappearing in adolescence)
- Linear atrophic alopecic lesions.
- Dental abnormalities
- Wooly hair, nail abnormalities
- Retinal disorders.
The presence of at least one major criterion is required while the presence of minor criteria supports the diagnosis of IP.
IP is most commonly reported to have been associated with CNS, skeletal, and dental anomalies; however, there have been rare reports of it being associated with cardiac abnormalities. In a study by Urban et al., one child with IP had strabismus and an associated atrial septal defect.
Godambe et al. reported an infant with IP presenting with pulmonary hypertension and marked tricuspid and pulmonary regurgitation and bidirectional atrial and ductal shunting with a small ASD.
| Conclusion|| |
In our case, according to the family history, there was no sign of X-linked dominant inheritance pattern; thus, possibility of sporadic mutation has to be considered. This baby presented to us with verrucous stage at birth with nail dystrophy and on investigation was found to have ASD. There are very few case reports of IP with congenital heart defects; we report this case in view of its rarity.
