Keratitis–ichthyosis–deafness (KID) syndrome is a rare congenital multisystem disorder, with a reported prevalence of less than one per 1,000,000, characterized by keratitis with corneal neovascularization, cutaneous manifestations including palmoplantar hyperkeratosis, leather grain-like keratoderma, nail dystrophy, alopecia, ichthyosiform scaling, and bilateral sensorineural hearing loss.[1] These changes occur at or before puberty.

First described by Burns in 1915, and the KID acronym was coined by Skinner and colleagues in 1981.[2] To date, approximately 100 cases of KID syndrome have been reported in the literature.[3]

We report a case of a 10-year-old female who presented with widespread hyperkeratotic scaling, severe photophobia, and congenital deafness, diagnosed as KID syndrome having a classical triad. This patient is the only child of non-consanguineous parents. There was no similar family history.

There was no history of the presence of collodion membrane at birth. Within few weeks of birth, progressive, generalized xerosis developed and the entire body was covered with hyperkeratotic scales over an erythematous base giving the appearance of underlying erythroderma. Lesions over the body had a rough and grainy texture [Figure 1]a. The whole face was covered with thick yellowish scales with spared lips and periorbital regions. Presence of alopecia over the scalp as well as eyebrows and eyelashes was noticed [Figure 1]b. Few lesions had a verrucous appearance, especially over the lower limbs [Figure 1]c. The patient had severe photophobia, and ophthalmological examination showed conjunctivitis, profuse corneal vascularization, opacification, and grossly reduced visual acuity [Figure 2]a and [Figure 2]b. The plantar and palmar surfaces presented with diffuse keratoderma having abundant and course scales [Figure 3]a, [Figure 3]b, [Figure 3]c. All the nails were yellowish and thickened with subungual hyperkeratosis. The patient had complete sensorineural deafness that was congenital, which eventually lead to mutism. Mucous membranes and dentition were normal. Sweating was reduced and mild mental retardation was evident. Because of blindness, deafness, and mutism, IQ test could not be done. There was no associated congenital or systemic abnormality found. Skin biopsy and Genetic study could not be done.

The patient was treated with topical emollients and keratolytics i.e., salicylic acid, which led to a significant decrease in keratotic lesions [Figure 4]a, [Figure 4]b, [Figure 4]c. She was also advised to wear a hearing aid and undergo auditory rehabilitation. Artificial tears were prescribed by an ophthalmologist. However, she was lost to follow-up after second visit.

Cases of KID syndrome are mostly sporadic, but both autosomal recessive and dominant inheritance have been reported. It is genetically heterogeneous and is caused by missense mutations in the GJB2 gene encoding for connexin 26 protein, which clusters at chromosome 13q12.[4] Familial cases are rare. Only twelve families affected by this disorder were described till 2014.[1],[5]

Histopathology reveals saw-tooth epidermal morphology with basket weave hyperorthokeratosis and follicular plugs.[6] These features are not consistent with the histopathology found in ichthyosis thus some authors suggest ichthyosis to be a misnomer in KID syndrome.

Angular cheilitis frequently develops and chronically fissured lips and gingival hyperemia have been described.[7] Sparse hair, hypohidrosis, dystrophic nails, and abnormal dentition represent additional features. Patients have increased tendency to develop mucocutaneous infections with bacteria, fungi, and viruses.[8]

Ocular findings, usually, start within the first year of life and are progressive. These include vascularizing keratitis, opacification of cornea, dry eyes, blepharitis, and conjunctivitis. Non-progressive, congenital, sensorineural hearing loss is consistently present.[8] Although hearing loss is in the form of sensorineural type, conduction pathologies due to external otitis and otitis media can also be seen. Follicular occlusion triad (dissecting cellulitis of scalp, hidradenitis suppurativa, and acne conglobate) was also reported in one patient.[9] Patients with this syndrome are considered to be at lifelong risk of development of squamous cell carcinoma of the skin or of the tongue and buccal mucosa at an unusually young age.[1] One case of ocular surface squamous neoplasia has also been recently reported.[10]

The treatment consists of keratolytic, topical emollients and antiseptic, antibiotic, antimycotic, and systemic retinoids.[1] Lubricating and anti-inflammatory agents have variable success in managing ocular disease, and cochlear implants have restored hearing in several affected individuals.[8] Close monitoring of the skin and oral mucosa for the development of malignancy is essential.
