We report a case of a 46-year-old man with ulcerative colitis being treated with oral prednisolone and azathioprine. Two weeks after the initiation of azathioprine he presented with fever, fatigue, myalgias and arthralgias and a painful cutaneous eruption that was most marked in a sun-exposed distribution. This was accompanied by loose, non-bloody diarrhoea. Histopathological assessment of a skin biopsy supported a diagnosis of a neutrophilic dermatosis. The azathioprine was temporarily withheld and oral prednisolone was increased as it was thought that the neutrophilic dermatosis was associated with the underlying ulcerative colitis. The patient's symptoms and cutaneous eruption resolved quickly and azathioprine was re-introduced. Within 24 h, systemic symptoms returned along with a florid recrudescence of his cutaneous eruption. This rapidly improved upon withdrawal of azathioprine.
This study supports the view that dermatological surgery, including significant procedures such as Mohs micrographic surgery, flaps and grafts, can be performed on an ambulatory basis in an office-based procedure room setting, with low complication rates.
Western Australia has only two superficial radiotherapy units, one of which is located at Fremantle Hospital, and run by the radiation oncologists of Perth Radiation Oncology Centre. A 3-year retrospective review was undertaken of all patients who underwent treatment at this unit from 1999 to 2001. Patients were identified from the unit's log book, and data was collected from their files. For malignant skin conditions, 369 lesions were treated in 259 patients over the study period. The patients' median age was 76 years. A wide variety of conditions were treated, but the most common diagnoses were basal cell carcinoma (237 lesions) and squamous cell carcinoma (92 lesions), most commonly located in the head region. The most frequently used treatment schedule was 36 Gy in six fractions over a 3-week period. Where radiotherapy was administered as primary treatment, the diagnoses had been biopsy-proven in only 53% of cases. Fifty-four patients underwent treatment of benign skin disease over the study period; most commonly keloid scars (41 patients) followed by warts (six patients). We conclude that superficial radiotherapy has a distinct role in dermatology, particularly for skin carcinomas around the nose and eyes, which cannot presently be superseded by electron beam therapy.
Background and Aim. The optimum management of Bowen's Disease (BD) is undefined. A review of current practice is required to allow the development of best practice guidelines. Methods. All BD cases, diagnosed in one UK centre and one Australian centre over a year (1 July 2012–30 June 2013), were analysed retrospectively. Patients with BD were identified from histopathology reports and their medical records were analysed to collect demographic data, site of lesion, and treatment used. Results. The treatment of 155 lesions from the UK centre and 151 lesions from the Australian centre was analysed. At both centres BD was most frequently observed on the face: UK had 70 (45%) lesions and Australia had 83 (55%) lesions (P = 0.08). The greatest number of lesions was managed by the plastic surgery department in the UK centre, 72 (46%), and the dermatology department in the Australian centre, 121 (80%). The most common therapy was surgical excision at both centres. Conclusions. In both UK and Australia, BD arises on sun-exposed sites and was most commonly treated with surgical excision despite a lack of robust evidence-based guidelines.
We report the case of a 2-year-old boy with Hirschsprung's disease who developed perianal pseudoverrucous papules and nodules subsequent to persistent diarrhea and stool leakage after Giardia infection. Bleeding from the papules resulted in iron deficiency anaemia requiring blood transfusion and iron infusion. Topical therapies used over 6 months were of limited benefit and colostomy was considered, but the condition completely resolved after commencement of oral loperamide. This demonstrates that perianal pseudoverrucous papules and nodules can be severe but are entirely reversible upon removal of the source of skin irritation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
