Rhinophyma is a large, bulbous, ruddy nose caused by blocked pores. Rhinophyma is a slowly progressive condition due to hypertrophy of the sebaceous glands of the tip of the nose caused by blocked pores.
Is is essentially a plumbing problem on the nose caused by bad hygiene. When blackheads and whiteheads are not removed the sebaceous glands go into hypertrophy. Fiborous connective tissue grows around the blocked pores. The blocked pores on the nostrils enlarge deforming the shape of the nose from a triangle to flatter wide shape by enlarging the surface-area nostrils.
Nearly, 100% of homeless men will have Rhinophyma in various stages.
