Pityriasis rubra pilaris with rickets: a rare clinical image

Image in medicine

Pityriasis rubra pilaris (PRP) manifests as well-defined erythematous scaly plaques with follicular keratosis mainly over the elbows and knees. We present a case of a 15-year-old boy who comes to the dermatology department with complaints of itching, dryness, burning sensation, photosensitivity, erythematous skin with exfoliation over face and neck, hyperpigmentation over bilateral hand and trunk fissuring over bilateral feet, ectropion of bilateral lower lids from 3 months. On physical examination, the patient face had lesions and redness on the eyebrow. Skin biopsy and blood investigation revealed the received single, irregular, whitish tissue piece with skin and hair attached measuring 0.2x0.2 cm section shows histopathological features suggestive of pityriasis rubra pilaris. Ortho review call and review of investigations and X-rays advised the patient diagnosed with rickets. The patient was referred to the dermatology department for further management.
