	*Body Site:*	foot / toe	*Age:*	15 months
	*Contributor:*	Scott Krugman, MD
	*Description:*	large tense bulla on a red base
	*Comments:*	This 15-month-old boy was evaluated in the emergency room for a swollen toe. According to his mother she came home and found him wearing shoes that were too small. He had actually kicked off the shoe on the foot that was not affected. Although one should always consider nonaccidental injury with lesions like this, accidental pressure injuries can result in edema and blistering. This process might be exacerbated by low temperatures and water such as in trench foot type injuries.

	*Diagnosis:*	GANGRENE / ISCHEMIA	*Category:*	cutaneous sign of systemic disease / diabetes mellitus associated
	*Body Site:*	foot / toe	*Age:*	54 years
	*Contributor:*	Julie Jefferson, MD
	*Description:*	cool dry scally purple well demarcated plaques Middle-aged man with dry gangrene due in part to both polycythemia vera and severe peripheral vascular disease. Two types of gangrene exist, dry and wet gangrene. Dry gangrene is due to tissue ischemia. Many diverse etiologies exist including acute arterial blood clot, arteriosclerosis, and Buerger�s disease. Dry gangrene generally produces cool, dry, and discolored appendages with no oozing fluid or pus. In contrast, wet gangrene often produces an oozing fluid or pus. Wet gangrene results from an untreated (or inadequately treated) infection at a site where the local blood supply has been significantly reduced or stopped by tissue swelling, bacterial toxins, and/or local gas production. If left untreated, gas gangrene may result in sepsis and death within a few hours or days.
	*Comments:*	A 54-year-old diabetic developed ischemia and subsequent gangrene of the toes on his left foot.

	*Diagnosis:*	ONYCHOMYCOSIS / TINEA PEDIS / NAIL DYSTROPHY	*Category:*	nail disorders / diabetes mellitus associated / infections and infestations
	*Body Site:*	nail, foot / foot toe	*Age:*	39 years
	*Contributor:*	Julie Jefferson, MD
	*Description:*	nail thickening, subungual debris and nail atrophy
	*Comments:*	This 39-year-old diabetic had thickened, friable toe nails with subungual scale involving all toes but the third. The nail on the third toe was atrophic Onychomycosis is an infection of the nails caused by dermatophytes, yeasts, and/or moulds. Diabetes mellitus is a predisposing factor for onychomycosis. The prevalence of onychomycosis increases with advancing age and ranges from 10-40%. Onychoatrophy, or the atrophic loss of a nail, follows an irreversible scarring process involving the nail matrix thus preventing further growth of the nail plate.
