Protean manifestations of human papillomavirus type 60 infection on the extremities.

BACKGROUND: Human papillomavirus type 60 (HPV-60) induces a ridged wart or an epidermal cyst on the sole of the foot, exhibiting identical pathological changes, with a single refractile eosinophilic intracytoplasmic inclusion body in infected cells. However, there is no information on the role of HPV-60 in the development of cutaneous lesions on other anatomical sites. OBJECTIVES: To perform the clinicopathological analysis of various cutaneous lesions of a patient in relation to HPV genotype. PATIENT: A 50-year-old male patient developed multiple papules, plaques and nodules on his hand, arm and legs. RESULTS: Clinicopathologically, the lesions were classified into three categories. A common wart on the finger showed papillomatosis and acanthosis characterized by numerous keratohyalin granules. Plane warts on the arm showed perinuclear vacuolization of the cells in the upper Malpighian layer. On the other hand, a pigmented papillomatous nodule on the finger, and the other lesions on the hands and legs exhibited similar histological features with a unique cytoplasmic eosinophilic inclusion body. All the three categorized lesions were equally positive for HPV capsid antigen by immunohistochemistry. By blot hybridization analysis for HPV sequences, it was revealed that a common wart on the finger and plane warts on the arm harboured HPV-27 and HPV-3, respectively, while all the other lesions harboured HPV-60. The histological localization of each viral DNA was confirmed in the corresponding lesions by in situ hybridization. CONCLUSIONS: HPV-60 is able to induce papular and nodular lesions on the extremities.

Treatment of necrobiosis lipoidica with topical psoralen plus ultraviolet A.

BACKGROUND: Necrobiosis lipoidica (NL) is a rare skin disease, mostly seen on the legs and often occurring in patients with diabetes mellitus. The disease belongs to the idiopathic cutaneous palisading granulomatous dermatitides associated with a degeneration of collagen, thus leading to skin atrophy. Application of topical corticosteroids is the most widely used treatment but the results are not always satisfactory and may worsen skin atrophy. Preliminary studies in patients with NL have shown a clinical response with psoralen plus ultraviolet (UV) A (PUVA). Objectives To study the effect of topical PUVA on NL in a multicentre prospective study. METHODS: Thirty patients (27 women and three men) including 13 with insulin-dependent diabetes mellitus, with a diagnosis of NL proven by histopathology, were included. All patients had been unsuccessfully treated with topical and/or intralesional corticosteroids. Patients were treated twice weekly with an aqueous gel containing 0.005% psoralen followed by irradiation with UVA. Clinical photographs were taken for evaluation. In addition, 20-MHz high-frequency ultrasound analysis was performed in 10 patients to evaluate the thickness and density of the dermis during topical PUVA therapy. RESULTS: Five patients (17%) showed complete clearing (healing of ulceration and disappearance of erythema) after a mean of 22 exposures (range 15-30). Eleven patients (37%) showed improvement, defined as healing of ulceration and/or reduction of erythema, after a mean of 23 exposures (range 11-42). Ten patients (33%) showed no effect and four patients (13%) worsened during topical PUVA therapy. The treatment results of the patients who suffered from diabetes mellitus were not different from those who did not have diabetes mellitus. No difference was seen in mean dermal thickness (1666 vs. 1706 micro m) and density (17 vs. 16 units) before and after topical PUVA therapy. Side-effects were seen in 10 patients: hyperpigmentation (n = 4), blistering (n = 4) and bacterial infection (n = 2). CONCLUSIONS: Topical PUVA may be a useful treatment modality for NL in patients not responding to topical or intralesional corticosteroids.

Erosive pustular dermatosis of the leg associated with compression bandaging and fungal infection.

BACKGROUND: Erosive pustular dermatosis of the leg (EPDL) has been described in association with venous insufficiency and atrophy of the skin of the lower leg. Like erosive pustular dermatosis of the scalp, this disease has also been reported to be a non-infective condition. OBJECTIVES: To investigate the clinicopathological features and, where possible, the aetiology of clinical EPDL. METHODS: We identified a group of patients undergoing continuous compression bandaging for venous dermatitis of the legs and/or predominantly venous leg ulceration with clinical features described in patients with EPDL. They were investigated by skin biopsy, patch testing and microbiological tests for the presence of bacteria and fungi. RESULTS: Twenty-four of 400 (6%) patients were noted to have pustules on the leg(s). There was laboratory evidence of fungal infection in 13 of 24 patients (54%), with complete and sustained resolution of pustules after antifungal treatment. Pustulation in the other 11 patients (46%) was unresponsive to antibiotics for confirmed bacterial infection; some improvement was seen with potent topical corticosteroids but full clearance was achieved only after a switch from continuous four-layer compression bandaging to the use of intermittent long stretch compression. CONCLUSIONS: EPDL is a fairly common clinical picture seen in patients undergoing continuous compression bandaging. It may be produced by opportunistic, particularly fungal, infection. In almost half an infective aetiology cannot be demonstrated and a pyoderma gangrenosum-like process may be implicated.
