The first pattern of growth is that the melanoma remains benign over the lifespan of the affected individual. The tumors remain localised and generally cause no dysfunction unless they grow large enough to impede surrounding structures. The second pattern of growth is for the melanomas to remain benign for many years then to suddenly turn malignant. It is thought that this pattern occurs when the tumor is disturbed in some way. Biopsy or attempted excision may trigger malignancy. The final growth pattern is for the melanoma to present as malignant and metastatic from the onset. This form of melanoma is considered rare.
Diagnosis of melanoma can be made through signs and symptoms or through needle aspiration and histology.
In most cases no treatment is required. In cases where the tumors interfere with urination, defecation or with tacking, surgical excision may be implemented. Oral , for a minimum of three months has been shown to stop, or reverse tumor growth. For many individuals the cost of such treatment is prohibitive and cimetidine use may be restricted or regulated for some competitive events.
Cystic Skin Diseases
Antheroma of the False Nostril Antheroma of the false nostril is commonly called a “false nostril cyst”. As its common name implies this disorder involves the formation of a cyst in the false nostril.
The cause is idiopathic and often
.
It is an accumulation of cell debris within the tissue. Acquired cysts are often formed around a retained hair follicle, while congenital cysts are formed around a collection of germinal that is misplaced.
No predispositions have been reported but it seems more common in the young.
Cysts are most commonly found at the apex of the false nostril. Cysts occur unilaterally and range in size from a few millimetres to ten centimetres. The cyst itself is a firm nodule filled with decomposed , which is a grey, greasy semi-solid.
Diagnosis can be made through signs and symptoms and through needle aspiration to determine the nature of the fill material.
Generally, no treatment is required for antheroma of the false nostril; however larger lesions may be surgically excised if the lesion is unsightly or interferes with respiration.
