An interesting case of neurofibroma of face

A 45 years old female, presented with complains of Painless large swelling over right side of nose and upper lip (Fig. 1) since childhood. The swelling was present since childhood, was initially the size of a peanutand gradually progressed to the present size of a lemon. There was a gradual increase in size of the swelling. There was no pain associated with the swelling. She also complained of similar swellings all over the body (Fig. 2) and right nasal obstruction. patients father and brother have similar swellings all over the body. On examination a Single, large diffuse irregular swelling measuring 6 X 5 cms over the right alae of the nose extending to the upper lip and nasolabial fold, soft in consistency, non tender.


Sir,
Neurofibromatosis or Von Recklinghausens disease is rare and found only in 1-4000 births.It is Autosomal Dominant, Involving chromosome 17.It is associated with pigmented spots (coffee coloured) in the skin, commonly seen on the back, abdomen and limbs (café au lait spots) [1].

On ophthalmic examination, Lisch nodules were present over iris.No evidence of optic glioma on fundoscopy.
ENT Examination-Normal.A provisional diagnosis of Neurofibromatosis Type 1/Von Recklinghausens disease was made systemic examination was normal and all routine investigations were normal.Debulking was planned Incision was made along the edge of the swelling along the alae of the nose and the lip.Incision was deepened till Orbicularis Oris.Then entire swelling was elevated off the muscle.Impression-Excised swelling shows diffuse neurofibroma.

Letter to the Editor
Neurofibromatosis or von Recklinghausens disease is rare and found in1-4000 births.It is autosomal dominant, involving chromosome 17.It is associated with pigmented spots (coffee coloured) in the skin, commonly seen on the back, abdomen and limbs (café au lait spots).Axillary freckling and lisch nodules may be present [1,2].Diagnostic criteria include two or more of the following [2,3]: Six or more café-au-lait spots 1.5 cm or larger in postpubertal individuals, 0.5 cm or larger in pre-pubertal individuals.
Two or more neurofibromas of any type or one or more plexiform neurofibroma.
Freckling in the axilla or groin.

Optic glioma (tumor of the optic pathway).
Two or more Lisch nodules (benign iris hamartomas).
A distinctive bony lesion: Dysplasia of the sphenoid bone or dysplasia or thinning of long bone cortex.
A first-degree relative with NF1.
Treatment -Excision/Debulking.The patient described here is a very typical case of NF-1 which presents a considerable interest because of the high generalization of the skin lesion.In such cases, a detailed patient investigation is required,because of the possibility for generalized involvement of other organs.The proper clinical and genealogic analysis is important for the determination of genetic risk and prognosis for relatives of proband.The treatment of such kind of patient is surgical,   seeking to achieve cosmetic improvement and may be only palliative.
