Antibacterial activity of methyl aminolevulinate photodynamic therapy in the treatment of a cutaneous ulcer.

We describe a 79-year-old female with a chronic venous ulceration infected by Staphylococcus aureus and Enterococcus faecalis and not responsive to conventional treatments. The patient was treated with Methyl-Aminolaevulinate Photodynamic Therapy (MAL-PDT). After four weeks the cutaneous swabs become negative and we observed a significant clinical improvement.

Skin ulcers in a patient afflicted with microscopic polyangiitis.

Systemic vasculitis is a group of heterogeneous diseases characterized by inflammation and blood vessel walls necrosis. Usually the skin is one of the first organs involved, especially with damage of small to medium size vessels. The cutaneous patterns may help clinicians to diagnose these diseases at the beginning of their course, preventing complications due to internal organ involvement.

[Pyoderma gangrenosum: case series].

Pyoderma Gangrenosum (PG) is a rare ulcerative cutaneous condition with distinctive characteristics, and the aetiology is not clear yet. PG is commonly associated with inflammatory bowel disease (Ulcerative Colitis and Crohn's disease). The features of PG are not specific histopathologically and for this reason diagnosis is based on clinical feature.

The use of elastocompressive therapy in a patient with acroangiodermatitis of the lower limb.

 Acroangiodermatitis is a rare vasoproliferative disorder, usually affecting the lower limbs and is associated with congenital or acquired vascular conditions. There are two variants of acroangiodermatitis-Mali type (associated with venous hypertension) and Stewart-Bluefarb type, which is associated with arteriovenous malformation, or acquired iatrogenic arteriovenous fistula in patients with chronic renal failure. Acroangiodermatitis is clinically characterized by angiomatous papules and plaques, which mimics Kaposi's sarcoma.
