Peyronie's_disease
This one is frightening.
Although the popular conception of Peyronie's disease is that it always involves curvature of the penis, the scar tissue sometimes causes divots or indentations rather than curvature. The condition may also make sexual intercourse painful and/or difficult, though it is unclear whether some men report satisfactory or unsatisfactory intercourse in spite of the disorder.

Buried penis
Fatties with huge guts get this one.
Buried penis (also known as hidden penis or retractile penis) is a congenital or acquired condition in which the penis is partially or completely hidden below the surface of the skin. A buried penis can lead to urinary difficulties, poor hygiene, infection, and inhibition of normal sexual function.

Paraphimosis
If this condition persists for several hours or there is any sign of a lack of blood flow, paraphimosis should be treated as a medical emergency, as it can result in gangrene.

Preputioplasty
Mostly funny and fucked up because the article comes with this image.
Yes, somebody drew that.
Phimosis
Another article with lots of dick pictures. Every guy has heard of Phimosis or experienced it, because of the ouch factor. The good part in the article was this:
US president James Garfield was assassinated by Charles Guiteau in 1881. Guiteau's autopsy report indicated that he had phimosis. At the time, this led to the speculation that Guiteau's murderous behavior was due to phimosis-induced insanity.
