| Abstract|| |
Olmsted syndrome (OS) is a rare disorder characterized by the combination of periorificial, keratotic plaques, and bilateral palmoplantar keratoderma. Synonyms are mutilating palmoplantar keratoderma with periorificial keratotic plaques (ORPHA659, MIM #614594 and #300918). A number sign (#) is used with this entry because of evidence that mutilating palmoplantar keratoderma with periorificial keratotic plaques (OS) is caused by heterozygous mutation in the TRPV3 gene on chromosome 17p13.2. We report three cases of OS, two females and one male in the same family, who presented with palmoplantar keratoderma, sparse scalp hair, cheilitis, and periorificial fissures. We are reporting the cases due to the rarity of occurrence and to highlight the trichoscopy findings.

| Introduction|| |
Olmsted syndrome (OS; mutilating palmoplantar keratoderma and periorificial involvement) is characterized by the presence of congenital, diffuse, symmetric, sharply marginated, mutilating palmoplantar keratoderma with periorificial hyperkeratosis.
| Case Report|| |
Three siblings of age 12, 10, and 6 years born of parents with consanguineous marriage, full term normal delivery with normal developmental milestones were brought with complaints of hair loss and palmoplantar keratoderma at the age of 2–3 years. No history of similar lesions in the family. Gradually lesions extended to knees and elbows.
On examination, children were moderately built and nourished. General and systemic examinations were within normal limits. There was palmoplantar keratoderma in all three siblings [Figure 1] and [Figure 2]. In two children, severe cheilitis, glossitis and keratotic plaques, and fissures around mouth were present. Scalp showed sparse hair with keratotic papule and follicular prominences, few scattered hair were thin and grew up to 1–2 cm in length [Figure 3]. Psoriasiform plaques were seen on elbows and knees. Paronychia and irregular dystrophy of finger and toe nails were present. The boy also had hypopigmented macules on the scalp. All routine blood and urine investigations were within normal limits.

Trichoscopy showed black dots, yellow dots in plenty. Tapered and thin hair, angulated hair, kinky gray hair, also had comma-shaped, “V” hair, broken hair, and vellus hair. The gap between hair follicles was more with follicular prominences [Figure 4].

| Discussion|| |
OS is a rare congenital disorder characterized by palmoplantar and periorificial keratoderma, alopecia in most cases, and severe itching. Until recently, only 46 individuals had been reported, including 36 sporadic cases and four families containing ten affected individuals. The definitive mode of inheritance was still uncertain, and autosomal-dominant, X-linked-dominant, and X-linked-recessive modes of inheritance had been proposed. Cambiaghi et al. reported transmission in two monozygotic male twins. They suggest that this condition is inherited as an X-linked dominant trait with reduced expression in female subjects. A case of a 6-year-old Indian girl in one report and two more unrelated female cases in another were reported., Whereas in our case, three siblings in a single family were affected, out of which two were females.
The diagnosis of the disease depends on clinical features. The two major ones are the symmetrical involvement of keratoderma of the palms and soles, and the symmetrical hyperkeratotic plaques around the body orifices. It starts in the neonatal period or in childhood. In our case, we have palmoplantar keratoderma, glossitis, cheilitis, and keratotic plaques around the mouth, sparse scalp hair with follicular prominences, hypopigmented macules over scalp and psoriasiform plaques were seen on elbows and knees. OS patients often show nail abnormalities including dystrophic, lusterless, ridged, rough nails, hyperkeratosis, onychogryphosis, leukonychia, irregular curvatures, onycholysis, paronychia, subungual hyperkeratosis, and even absence of nails. In our case, we had paronychia and irregular dystrophy of finger and toe nails.
Ogawa et al. report a case of this rare syndrome diagnosed in a 48-year-old woman, who developed several squamous cell carcinomas of limbs and adenocarcinoma of the lung.
| Conclusion|| |
We have reported this case to highlight the trichoscopy findings, female preponderance, and rarity in occurrence.
