Abstract:
A 33-year-old man visited the outpatient department of the authors of this article with a large perineal mass. The patient was an active amateur racing cyclist. At physical examination the swelling resembled an accessory scrotum. Ultrasonography revealed a subcutaneous thickening but no intrascrotal abnormalities. Because of progressive symptoms the perineal tumour was surgically excised. Histopathologic examination revealed cell deficient and degenerative connective tissue. The tissue possibly contained a bursa. The tumour was diagnosed as perineal nodular induration, a rare lesion. These nodules almost invariably affect keen cyclists after sustained cycling. Recognition of perineal nodular induration is of particular interest to general practitioners, urologists and specialists in sports medicine.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
