Abstract

Cornu cutaneum or cutaneous horn is a rare clinical presentation resembling an animal horn. The lesion is often seen arising from sun-exposed skin surface. We report a case of Rhino-cutaneous horn which developed from the sun-protected surface of nasal vestibule. The broad based lesion was completely excised and microscopically proved to be non-malignant

Introduction

Cornu cutaneum or cutaneous horn is a relatively uncommon clinical entity consisting of a compacted hyperkeratosis over a hyperproliferative lesion and it resembles an animal horn1. The base of the lesion may be flat, nodular or crateriform. Cutaneous horn most often arises on the sun-exposed skin surface in elderly men, usually after fifth decade2. The lesion is found on scalp, face, pinna, eyelids, nose, neck, shoulders, hands and penis. The possibility of malignancy at the base of the lesion increases in men when compared with the age-matched women. Various histological variants have been documented at the base of the keratin mound therefore histopathological confirmation is often necessary to rule out benign, premalignant and malignant changes.

Case report

A 32 year old female house wife with fair complexion attended the ENT out patient department with complains of projectile mass from the left nostril (Fig.1) associated with pain and a sense of embarrassment since 8 months duration. There was no history of epistaxis or respiratory obstruction.

The clinical examination showed a hard keratotic conical mass protruding from the left nostril, painful on palpation. On careful anterior rhinoscopy a sessile mass was seen arising from the lateral wall of the vestibule about one cm. from the free margin. No such lesion was detected in the right nostril or other parts of the body. Examination of the neck did not reveal any clinical positive lymph nodes. The mass was clinically diagnosed as Rhino cutaneous horn from a sun-protected area of the vestibule of the left nostril. The lesion was excised (Fig.2) under local anesthesia after infiltrating the surrounding area of the lesion with 1:200,000 adrenline in xylocain with sufficient depth and safety margin. There was a minimal; bleeding and the defect was closed primarily by undermining the margins with 3-0 silk. An anterior nasal dressing with ribbon gauge impregnated with Fusidin(R) (sodium fusidate BP 20mg) ointment was done and a bolster applied. The patient was given an injection of Voltran(R) (diclofanic sodium) 75 mg. I/M and advised to take tablet of Voltran three times a day after meals for a period of two days. The anterior nasal pack was removed after 48 hours and thereafter only Fucidin ointment was applied locally for 5 days. The stitches were removed on day 5. Follow up period was uneventful without signs of recurrence. The histopathological examination showed squamous epithelial cells with keratine debris indicating a benign lesion.
