Etiopathogenesis
This section has been translated automatically.

Unexplained, probably genetic disposition.

Manifestation
This section has been translated automatically.

Mainly occurring between the ages of 40 and 60.

Localization
This section has been translated automatically.

Dorsal side of the shaft of the penis.

Clinical features
This section has been translated automatically.

Palpable, longitudinal, stripy, plate-shaped or knotty hardenings on the back of the penis. Painful kinking of the penis during erection (>80% of patients), pain (50-70%) as well as in the case of more severe erectile dysfunction (30%) with possible impotentia coeundi.

Side effects: 30% of patients may experience Dupuytren's contracture and keloids or knuckle pads. S.a.u. Polyfibromatosis.

Histology
This section has been translated automatically.

Inflammatory vasculitic changes. Initially, fibromatosis, which is rich in cells and later poor in cells and rich in fibers, is manifested as well as metaplastic calcification and possibly cartilage and bone formation.

General therapy
This section has been translated automatically.

The treatment is difficult and often unsatisfactory. A standstill of the disease can be considered a therapeutic success. The course of the disease cannot be estimated, but spontaneous remission is possible (even after years) (approx. 30%).

It is important to inform the patient about the course of the disease. If necessary, psychotherapeutic support should be considered.

Prior to surgery (removal of fibromatous changes), the change should have been clinically halted for 6-9 months (otherwise high recurrence rate).

Progression/forecast
This section has been translated automatically.

Often progression despite therapy. In up to 30% of cases, spontaneous regression is also possible (especially in younger patients).

Therapeutic approaches in the treatment of induratio penis plastica

Indication	Example preparations and dosage		Remarks
Early stages	Antiphlogistic-externa like glucocorticoids and dexpanthenol cream	0.1% triamcinolone cream (e.g. triamgals)	Moderately helpful in initial stages
		0.25% prednicarbate (e.g. Dermatop cream)
		5% panthenol cream (Bepanthen)
	Intralesional glucocorticoids	Triamcinolone crystal suspension (e.g. Volon A 1:3 diluted with LA like scandicain) minimum amounts every 3 weeks	Especially in case of inflammatory changes
	X-ray soft X-rays	GD = 32 Gy, ED = 4 Gy at 8 week intervals	Especially helpful for pain relief; older, sharp-edged or calcified plaques are no longer accessible to X-ray therapy
Late stage (> 45%)	Operative penis straightening	e.g. Nespit process or ruffled plastic	Penis shortening + risk of surgically induced impotence
	Penile prosthesis		ultima ratio
Accompanying to all stadiums over 1-2 years	Vit. E high dosage	Vit. E 600-800 mg/day (e.g. Evion)	No adverse effects, but probably only little beneficial effects
	vitamin A	Retinol acetate 20 000 IU/day (e.g. retinol)
		12 g/day (e.g. Potaba-Glenwood)
	Potassium Paraaminobenzoate
