Abstract
Nail abnormalities are varied and numerous. They include warts, keratoacanthomas, onychomatricomas, fibrokeratomas, osteochondromas, tumors (ie, glomus, giant cell, Koenen's, and others), and Bowen's disease. Although the gravity of these conditions may vary, prompt diagnosis and treatment is of the utmost importance. This article discusses the most common defects associated with the nail unit and its surrounding tissue, as well as the differential diagnosis and treatment of these conditions.

Abstract
A 54-year-old HIV-positive homosexual man presented with erythematous and pigmented plaques on background erythema in the perianal region, histologically consistent with Bowen's disease. Perianal Bowen's disease represents high-grade anal intraepithelial neoplasia, which is considered a precursor lesion of invasive anal squamous cell carcinoma. This patient's anal intraepithelial neoplasia was unresponsive to multiple treatment modalities including cryotherapy, serial curettage and cautery, topical 5-fluorouracil and 5-aminolaevulinic acid photodynamic therapy. He progressed to develop a poorly differentiated squamous cell carcinoma of the anus three and a half years after the Bowen's disease was diagnosed. The squamous cell carcinoma was treated with combined chemoradiation. A recurrence of high-grade anal intraepithelial neoplasia was noted 6 months after completion of chemoradiation.

Abstract
Photodynamic therapy (PDT) by porphyrins and related tetrapyrrole derivatives is an emerging new treatment modality of tumors of lung, eosophagus and skin and of age-related macular degeneration. Phase III clinical trials for other applications such as re-stenosis after angioplasty are also underway. Under systemic conditions, the transport of porphyrin photosensitizers by serum low density lipoproteins and their specific delivery to tumor cells and vasculature is a determinant of treatment effectiveness. However, this effectiveness can be improved by increasing the selectivity of the photosensitizer uptake by tumors and by using photosensitizers absorbing light in the 660-800 nm range where tissues have the highest transmittance. Another treatment showing great promise is the PDT of skin cancers after topical application of the protoporphyrin IX precursor delta-aminolevulinic acid (or its ester forms). In all the cases, the photosensitizers should be rapidly excreted to avoid a long lasting skin photosensitivity.

Abstract
The incidence of skin cancer has been increasing for several years. This is the case in malignant melanoma as well as in squamous cell carcinoma and basal cell carcinoma. Skin cancer is most common among the elderly, but is now also more frequently found in younger people. Surgery is often the treatment of choice and this is still the case in malignant melanoma and most cases of squamous cell carcinoma. For basal cell carcinoma, Bowen's disease and actinic keratoses, however, alternative treatments should be considered. Today, dermatologists can offer patients with skin cancer several new treatments besides surgery. These new treatments seem to have the same efficacy but better cosmetic results compared to earlier treatments.

Abstract
Actinic keratosis (AK) is a common sun-induced precancerous neoplasm confined to the epidermis. The AK is the initial manifestation of a continuum of clinical and histologic abnormalities that progresses to invasive squamous cell carcinoma (SCC). Bowen's disease, also known as squamous cell carcinoma in situ, represents early SCC confined to the epidermis. More than half of all SCCs contain p53 tumor suppressor gene mutations. Like SCCs, the vast majority of AKs and Bowen's disease lesions are asymptomatic. Each AK and suspicious lesion should be treated before it progresses to invasive SCC. Destructive modalities, such as cryosurgery using liquid nitrogen and electrodesiccation and curettage, usually performed by a dermatologist, are the mainstays of therapy.

Abstract
There has been worldwide a significant rise in the incidence of epithelial skin tumors and their precursors in the past years with an increased number of younger patients affected. The risk factors are identified. The choice of the appropriate treatment for each individual is crucial. Major consideration include high cure rate, low long-term recurrence rate and few side effects. In the following article different therapeutic approaches for actinic keratoses, Bowen's disease, basal cell carcinoma and squamous cell carcinoma are presented and analysed.

Abstract
Skin cancers are the most commonly diagnosed cancer in the UK, and their incidence is growing. They can present in all age groups, and are particularly common in older people, but the incidence among younger people is increasing. However, the majority of skin lesions are not malignant. In this, the first of two articles, the author discusses the range of common benign growths that can be mistaken for cancers, as well as the precancerous lesions that can become a cause for concern if untreated. The second article will examine the common malignant lesions.

Abstract
Each year around 15 per 100,000 people in the UK develop intra-epidermal squamous cell carcinoma--Bowen's disease. The lesions of Bowen's disease are slow-growing, erythematous scaly skin plaques that cause few, if any, symptoms. However, if left untreated, they progress to invasive squamous cell carcinoma in 3-5% of patients. Here we review the management of Bowen's disease.

Abstract
Squamous cell carcinoma in situ (SCCIS) of the skin is a problem commonly dealt with by dermatologists. The classic presentation, originally described by Bowen, is easily recognized, but presentation on some anatomical surfaces may be associated with less than typical features. Major aetiological factors for this disease are UV light, human papillomavirus infection and immunosuppression. The natural course of SCCIS is usually prolonged, with treatment being appropriate, but not urgent. The choice of therapy requires consideration of the location of the lesion, and a desire for a high cure rate without causing loss of form, function or cosmesis. The immunomodulatory agent imiquimod has offered a significant advance for the topical treatment of SCCIS. Our improved understanding of the underlying biology of SCCIS permits us to make rational choices of treatment. In the future we may be able to determine which of these lesions may progress to invasive disease, and help us select the most effective therapy.

Abstract
BACKGROUND In the current economic climate, it is important to justify the cost of treatments used in dermatology, particularly where cheaper alternatives exist. OBJECTIVES To determine which treatment modality commonly used for Bowen's disease is associated with the lowest cost to the National Health Service. METHODS A cost-minimization analysis was used to compare the following six treatments for Bowen's disease: cryotherapy, curettage and cautery, excision, laser ablation, photodynamic therapy and 5-fluorouracil. These are all known to have similar recurrence rates. Information regarding use of these treatment modalities was extracted from a literature review. Costs were determined from published data, average wholesale prices of medications, staff salary pay scales and health economics departments. RESULTS The results show that, if treatment is indeed undertaken, a single lesion of Bowen's disease is most cheaply treated by curettage or excision biopsy under local anaesthetic, and most expensively treated by photodynamic therapy. The usefulness of this information has to be taken in the context of the study design, outcome measurements and base assumptions. CONCLUSIONS Valid costing studies such as this, in conjunction with evidence of effectiveness and safety, can provide guidance for resource allocation and treatment decisions.

Abstract
BACKGROUND Penile intraepithelial neoplasia (PIN) is the term used to describe erythroplasia of Queyrat (EQ), Bowen's disease (BD) and bowenoid papulosis (BP). These conditions are distinct clinical entities and have different epidemiological and aetiological associations and prognostic implications. OBJECTIVES To describe the presentation and treatment of patients with PIN. METHODS Thirty-five patients presenting with PIN over a 7-year period are described. RESULTS Our observations include: (i) patients with BP are younger than those with EQ or BD and sometimes have a history of immunosuppression; (ii) patients with BP usually have a history or clinical evidence of previous genital human papillomavirus infection; (iii) patients with EQ often have a concurrent penile dermatosis (lichen sclerosus or lichen planus); (iv) patients with PIN are usually uncircumcised; and (v) response to treatment of BP depends on the integrity of the immune system. CONCLUSIONS We recommend vigorous treatment of all patients with PIN, including circumcision. Smoking should be actively discouraged. Patients should have life-long follow-up and partners of patients with BP should be screened for other forms of intraepithelial neoplasia (cervical and anal).

Abstract
Bowen's disease is a form of squamous cell carcinoma in situ, in which local hyperthermia may be efficacious. We studied 8 patients with Bowen's disease to ascertain whether hyperthermia can be effective against it. As a heat source, disposable chemical pocket warmers were applied daily with pressure directly to the lesion site while the patient was awake, and the clinical course was observed for 4 to 5 months. The lesion was then excised and examined to determine the histopathologic effects. The results showed efficacy in 6 cases, in which the nodular and invasive lesions and the erythematous patches abated; then the lesions disappeared, leaving deposits of pigment (complete remission). In one case, the signs improved by at least 50% (partial remission); in the other case, there was only slight palliation (no response). As for the posttreatment histopathologic effects, tumor cells were eliminated in 3 cases, isolated tumor cells were seen in 3 cases, and there was no change in 2. Although the treatment did not yield perfect results, it represents a major improvement of hyperthermic therapy and is one effective method of treating Bowen's disease.

Abstract
BACKGROUND Therapy for Bowen's disease is essential to prevent invasive squamous cell carcinoma and metastases. Surgical excision is preferred because of the low relapse rate, but it may result in scar contracture, especially in the digit. OBJECTIVE This study was undertaken to evaluate the effectiveness of carbon dioxide laser for Bowen's disease of the digit. METHODS Patients with biopsy-proven Bowen's disease of the digits were recruited from the Department of Dermatology, Siriraj Hospital during the period 1992-1998. Risk factors were assessed. The lesion and 4 mm of surrounding clinically uninvolved skin were vaporized by means of the carbon dioxide laser. Wounds were managed by second intention. Patients were followed up at 1 week, 4 weeks, 6 months, and yearly thereafter if applicable. RESULTS During this 7-year period, only 6 patients with Bowen's disease of the digits were identified. Four of the 6 had a long history of exposure to arsenic from herbal medicines. Postoperative clinical appearance was mild atrophic skin and hypopigmentation. No functional impairment was found. Biopsy specimens taken after treatment showed a slightly thinned epidermis and mild fibrosis in the papillary dermis. There has been no evidence of recurrence in the 6 months to 7.7 years since surgery. CONCLUSION At least 67% of the patients affected by Bowen's disease of the digits had chronic arsenicism. It may be the earliest presentation of chronic arsenicism. Carbon dioxide laser provides ease of surgery, excellent cosmesis, preservation of function, and effective treatment for patients with Bowen's disease of the digits.

Abstract
The authors present a review of recent theories about clinical entity of Bowenoid Papulosis (P.B.), considering histological and etiopathogenesis aspects. The starting point of this review was recent observation of some clinical cases of P.B. The HPV is clearly involved in the start and the growth of this pathology. However, we have serious doubts regarding the etiopathology role of such virus of the pathology and the element of the start of a simil-neoplastic shape because the HPV was not found in the clinical shapes that we have examined. The frequent spread of the illness might give an answer to the immunology of the patient even though there was not significant immunity deficit in the previous cases that we have examined. Another remark was noticed by therapy writers. They are wondering whether they should practice a therapy called "wait" rather than treatment which is sometimes harmful and collateral effects. The last patients who have been treated by dtc in the beginning were restricted to local therapies with podofilotoxines in rare cases where they were examined after their treatment.

Abstract
The aim of this study was to determine current management practices of physicians caring for patients with perianal Bowen's disease. A questionnaire was sent to 1,499 members listed in the 1997 American Society of Colon and Rectal Surgeons Directory asking them how many patients they have treated and which operative or nonoperative treatment option they choose for small (< or =3 cm), large (> 3 cm), and microscopic lesions. Of 1,499, 663 (44.2%) surgeons responded. Not all respondents answered each item. Seventy-five per cent of surgeons surveyed (n = 653) devote greater than 75 per cent of their practice to colon and rectal surgery. Of 642 respondents, 552 (86%) managed a total of <10 patients, and 90/642 (14%), > or =10 patients. Ninety-six per cent of respondents use wide local excision for patients with small lesions. Eighty-seven per cent of respondents use wide local excision for patients with large lesions. Seventy-four per cent treat patients with microscopic disease conservatively and without wide excision. The majority of surgeons caring for patients with perianal Bowen's disease are performing wide local excision for both small and large lesions. Microscopic disease was usually treated conservatively with observation alone.

Abstract
Bowen's disease is a well-known precancerous lesion, in which invasive squamous carcinoma may develop. However, it is rare that Bowen's disease, basal cell carcinoma, and internal malignancy develop in a single patient. We report a case of a 54-year-old male patient with Bowen's disease, basal cell carcinoma of the skin, and squamous cell carcinoma of the lung. Multiple scaly erythematous patches had developed several years earlier and were diagnosed as Bowen's disease by skin biopsy. The number of lesions increased and, five months ago, a right lower lobectomy was done for squamous cell carcinoma which was detected on a chest X-ray. Skin biopsies of two different sites revealed Bowen's disease and basal cell carcinoma. The arsenic level was increased in his hair specimen. Cryotherapy was applied.

Abstract
PURPOSE The aim of this study was to review the literature with regard to perianal Bowen's disease and anal intraepithelial neoplasia. METHODS A literature review was conducted from 1960 to 1999 using MEDLINE. RESULTS Perianal Bowen's disease and anal intraepithelial neoplasia are precursors to squamous carcinoma of the anus. They are analogous to and are associated with cervical and vulvar intraepithelial neoplasia, and have human papillomavirus as a common cause. Biopsy and histopathologic examination is required for diagnosis and to distinguish other perianal dermatoses. Treatment options range from aggressive wide local excision of all disease with negative margins to observation alone for microscopic lesions not visible to the naked eye. The disease has a proclivity for recurrence and recalcitrance. CONCLUSIONS Most surgeons caring for patients with perianal Bowen's disease and high-grade anal epithelial neoplasia use wide local excision, with an effort to obtain disease-free margins. Some authors have reported the advantages of ablative procedures such as laser ablation and cryotherapy. Microscopic disease found serendipitously in hemorrhoidectomy specimens can probably be treated conservatively with serial examinations alone. There is a lack of controlled data supporting an optimal treatment strategy. A multicenter controlled study comparing wide local excision with ablative procedures may be warranted.
