It is a rare and non-specific cutaneous lesion, characterised by hyperkeratosis. It usually occurs in old persons of either sex'. Exposed upper parts of the face specially the skin of the lids are more frequently the site of this lesion. These are commonly single, but may be multiple., sub Apart from the cases described by Duke-Elder we have come across two such case reports in the recent literature, From a study of I l1 cases of lid tumours at A.M.U. Institute of Ophthalmology we have come across two such cases of this rare clinical entity. These cases are being reported because of their clinical curiosity.
| Case Reports|| |
Case 1. Patient M.L. 65 years male reported with a small swelling of the right upper lid for the last one year. It was gradually increasing and there was no other I associated symptom.
On examination, there was a small horn like growth at the junction of lateral and middle third of the upper lid margin [Figure - 1]. It was dark brown in colour with a broad base and pointed apex. It was 8.0 mm long and measured 3.0 mm at the base. There was a small keratin plug covering the distal one third of the swelling. The swelling was freely mobile over the underlying structures and there was no induration of the adjoining area. The swelling was excised with a 2.0 mm margin of healthy skin.
Swelling was firm in consistency, and histopathological examination revealed concentric layers of keratin, moderate acanthosis, and a central core of blood vessels [Figure - 2] There was no evidence of malignancy or intraepithelial cell nest formation. There was no excessive pigmentation. On the basis of these finding the diagnosis of papilloma with hyperkeratosis was made.
The second case was a 45 years female with a similar swelling of 6 months duration. It was 4.0mm long 2.0mm at the base. The swelling was excised and histological examination confirmed the diagnosis.
| Comments|| |
A cutaneous horn is a keratotic protuberance resembling an animal horn. It may arise from papilloma, senile or seborrohic keratosis, inverted follicular keratosis, vulgaris or may accompany the Boweinoid changes in the epithelium, and keratoacanthoma., In our cases the basic lesion was papilloma, with superadded hyperkeratosis. Lever stressed that cornu cutaneum is merely a clinical term, whereas, histologically it is a hyperkeratotic papilloma.
| Summary|| |
Two cases of cornu cutaneum from a study of 111 cases of primary lid tumors have been reported.
