1/227. HPV 18-induced pigmented bowenoid papulosis of the neck.

    We describe the case of a 53-year-old man in whom pigmented bowenoid papulosis developed on the skin of the neck. By polymerase chain reaction with general primers for genital human papillomaviruses (HPV) and subsequent restriction enzyme cleavage we could demonstrate HPV 18-related dna in two biopsy specimens of the pigmented papules. To our knowledge, this report represents the first case of HPV 18-induced extragenital bowenoid papulosis of the neck. ( info)

2/227. Detection of human papilloma virus type 58 in a case of a perianal bowen's disease coexistent with adult T-cell leukemia.

    A case of bowen's disease (BD) that appeared in the perianal region of a 65-year-old Japanese woman coexistent with chronic adult T cell leukemia (ATL) is described. Histopathological findings revealed that irregularly arranged tumor cells with atypical nuclei throughout the epidermis, which itself disclosed hyperkeratosis, dyskeratotic cells, and clumping cells. Positive staining for HPV antigens was immunohistochemically seen in several nuclei of the tumor cells. Electron microscopic study of the tumor tissue disclosed virus particles of about 50 nm in diameter form the squamous cells. A positive band at 256 bp was obtained by PCR using HPV-L1 primer. The amplified dna by L1 primer completely corresponded to that of HPV-58. ( info)

3/227. Evidence that AEC syndrome and Bowen--Armstrong syndrome are variable expressions of the same disease.

    Several clinical disorders combine ectodermal dysplasia (ED) and cleft lip and/or palate (CL/P). These conditions have been recognized as a group of diseases with a narrow phenotypic spectrum and multiple points of overlap. We report a patient with a clinical diagnosis of AEC syndrome (ankyloblepharon, ectodermal defects, and CL/P) who additionally has some features observed in a different ED-CL/P disorder, Bowen-Armstrong syndrome. Because of this clinical overlap, we suggest that AEC syndrome and Bowen-Armstrong syndrome may be variable manifestations of the same pathologic entity. ( info)

4/227. bowen's disease showing spontaneous complete regression associated with apoptosis.

    Spontaneous regression is sometimes seen in malignant skin tumours. We report a 68-year-old woman whose bowen's disease showed spontaneous complete regression. Prominent infiltration of T cells and increased vascularity were found in the upper dermis of the regressed lesion. Strong expression of Fas (APO-1/CD95) antigen, an apoptosis-related tumour necrosis factor receptor family protein, in the primary lesion and faint expression following regression suggest the involvement of Fas-mediated apoptosis in the spontaneous complete regression of our patient's bowen's disease.

5/227. arsenic-related bowen's disease, palmar keratosis, and skin cancer.

    Chronic arsenical intoxication can still be found in environmental and industrial settings. Symptoms of chronic arsenic intoxication include general pigmentation or focal "raindrop" pigmentation of the skin and the appearance of hyperkeratosis of the palms of the hands and soles of the feet. In addition to arsenic-related skin diseases including keratosis, bowen's disease, basal-cell-carcinoma, and squamous-cell carcinoma, there is also an increased risk of some internal malignancies. arsenic-related diseases are common in areas of the world where the drinking water has a high arsenic content. In this paper, we describe a 35-year-old male patient who had arsenic-related keratosis, squamous-cell carcinoma in the palmar area of his left hand, and bowen's disease on his left thigh. The patient worked in a borax mine for 15 years, so he was exposed to arsenic in drinking water, airborne arsenic in his workplace, and had direct contact. The patient was treated for 11 months for arsenic-related keratosis until an axillary lymph node metastasis occurred; the lesion was excised and diagnosed to be malignant. bowen's disease was detected when the patient was being treated for cancer. No other malignancy was found. The patient is still receiving regular follow-up care. ( info)

6/227. anaphylaxis due to suxamethonium--manifested at induction of anaesthesia by bradycardia and cardiac arrest.

    This case report describes an unusual presentation of a severe anaphylactic reaction following induction of anaesthesia in an elderly male patient. Full recovery followed protracted resuscitation. ( info)

7/227. Detection of human papilloma virus type 56 in extragenital bowen's disease.

    A case of bowen's disease arising on the medial part of the first metatarsal bone of an 81-year-old Japanese woman is described. Histopathologically, proliferation of atypical cells was found throughout the epidermis. Electronmicroscopy revealed virus particles 40-50 nm in diameter in the nuclei of tumour cells at the granular cells just on or below the horny layer. Positive bands were obtained by polymerase chain reaction using a consensus primer of human papilloma virus L1 portion. Sequencing analysis of the amplified dna revealed the same base sequences and homology as human papilloma virus 56. To the best of our knowledge, this case is the first report in which human papilloma virus 56 was found in a case of extragenital bowen's disease. We consider it important to understand that human papilloma virus 56, often found in cervical lesions, can be detected in extragenital Bowen's diseases. ( info)

8/227. Isolated extragenital bowenoid papulosis of the neck.

    We report a case of extragenital bowenoid papulosis (BP) in a healthy immunocompetent 42-year-old man. The lesions occurred on the anterolateral aspects of the neck and were not associated with genital, oral, or periungual lesions. Lesional skin tested positive with the Digene hybrid capture system cocktail assay that identifies infection with a mixture of high to intermediate oncogenic human papillomavirus (HPV) types, including types 16, 18, 31, 33, 35, 45, 51, 52, and 56. This cocktail assay identifies infection with HPV types typically associated with high-grade squamous intraepithelial lesions and invasive carcinoma. This case represents the sixth case of isolated cutaneous BP occurring a significant distance from the genital region. ( info)

9/227. Bowen's diseases and basal cell carcinomas in a patient.

    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. ( info)

10/227. pneumocystis carinii infection presents as common bile duct mass biopsied by fine-needle aspiration.

    This paper describes a case of pneumocystis carinii (PC) presenting as a common bile duct intraluminal mass in an hiv-infected 30-yr-old homosexual man. In fine-needle aspiration smears, exuberant vascular proliferation associated with multinucleated giant-cell reactions was found within the granular exudate of PC. ( info)
