The literature reports an annual incidence of 5,900 cases of anal cancer in the developed countries. These involve three different anatomic zones: carcinoma of the anal canal, perianal carcinoma (formerly known as carcinoma of the anal margin, located at a distance of less than 5 cm from the anal margin), and carcinoma of the perianal skin (at a distance greater than 5 cm from the anal margin). Basal cell carcinoma of the perianal region is an uncommon tumor (0.27% of all diagnosed basal cell carcinomas) that in the majority of cases is treated by resection with disease-free margins. It must be differentiated from the basaloid and epidermoid variants of carcinoma, given that it has good outcome and its spread potential is practically null. 相似文献

Nail disorders frequently seen in daily practice may be inflammatory, infectious, tumoral, traumatic, or cicatricial. Surgical correction of the most common disorders is reviewed here. Treatment of the different types of ingrown nails as representative of the inflammatory diseases, the peculiarities in the treatment of an acute or a chronic hematoma, management of infectious diseases like chronic and acute paronychia, and different surgical techniques to treat a nail tumor depending where the problem is located, trying to prevent permanent postsurgical dystrophies are discussed. 相似文献

Necrotising fasciitis is a severe, life-threatening soft tissue infection. It produces an extensive cellulitis with severe involvement of subcutaneous tissue, fascia, muscle or both, resulting in necrosis of the tissue. All age groups, including neonates, can be affected. Patients with necrotising fasciitis present with more severe constitutional symptoms and have a poor outcome, unless aggressive antibiotic therapy and surgical debridement are instituted promptly. The debridement of necrotic tissue is imperative to control the infection, but results in deep wounds that require further treatment. In this study, the neonate was treated with alginate dressings and negative pressure therapy after resolution of cellulitis, with excellent results and no untoward events. 相似文献

An interesting case of subungueal squamous cell carcinoma in a 13-year-old girl is presented. The tumor presented as a pseudo-fibrokeratoma with melanonychia on the index finger. Biopsy was diagnostic and treatment consisted of Mohs micrographic surgery and secondary intention wound healing. This is one of the youngest patients ever reported with subungueal squamous cell carcinoma, and there is only one more case of pseudo-fibrokeratoma and melanonychia reported as initial skin lesions. 相似文献

We report an uncommon case of solitary subungual neurofibroma on the right first finger of a middle-aged healthy woman. Surgical excision was used for the treatment. Common clinical findings, treatment modalities, and reported recurrence rates in previous studies are reviewed. 相似文献

We report a 21-year-old farmer with a 4-year history of a nodular plaque with fistulas and induration of adjacent skin. The lesion had been treated surgically at another hospital, but recurred 2 years later.
Black, charcoal-like grains were observed draining through the fistulas. A biopsy specimen showed brown grains with filaments in an abscess surrounded by macrophages, giant cells, and lymphocytes. Culture demonstrated small white colonies of Madurella mycetomatis . The patient was treated with itraconazole for 6 months, followed by surgery. TNP was initiated in the immediate post-operative period, and copious granulation tissue was observed within 1 week. Autologous skin grafting was performed, and itraconazole was continued for an additional 3 months. Although necrosis of the graft ensued, the functional result was acceptable. The patient appeared free of disease at 18 months of follow-up.
Eumycotic mycetoma is an infectious and inflammatory process that occurs after traumatic inoculation of fungi through the skin. Surgery is the treatment of choice, but successful reconstruction may be challenging and recurrence is common. Topical negative pressure (TNP) promotes the formation of granulation tissue, which facilitates closure of deep wounds and chronic ulcers. This case illustrates that eumycotic mycetoma is difficult to treat. Whether TNP contributed to the successful outcome cannot be proven but, given the generally poor response of eumycetoma to therapy, we suggest that the role of TNP in the management of this disease merits attention. 相似文献

BACKGROUND: The techniques, drugs and depth of sedation for flexible fiberoptic bronchoscopy is controversial, and several reports consider that the routine use of sedation is not a prerequisite. We evaluate whether the addition of sedation with propofol improves patient tolerance, compared to local anesthesic of the airway only. METHODS: Eighteen patients with pneumonia undergoing flexible fiberoptic bronchoscopy were included in a randomized, single blind, prospective controlled study. The non-sedation group received airway topical anesthesia, whereas the sedation group received topical anesthesia and intravenous sedation with propofol. The degree of pain, cough, sensation of asphyxiation, degree of amnesia, global tolerance and acceptance of another bronchoscopy in the future were noted. Changes in blood pressure, heart rate and saturation of oxygen by pulse oximetry were also evaluated. RESULTS: The patients in sedation group had less cough (P < 0.05), pain (P < 0.01) and sensation of asphyxiation (P < 0.001). Global tolerance to the procedure was significantly better in the group under sedation (P < 0.01). These patients had total amnesia to the procedure (P < 0.0001), thus is more probable that will accept another bronchoscopy in the future (P < 0.01). There was a significant rise in heart rate and blood pressure in the patients without sedation. There were no differences in oxygen saturation (P = 0.75). CONCLUSIONS: Our results show that if we administer propofol for sedation, in addition to local anesthesia of the airway, the tolerance to the procedure is much better. Also it appears that sedation with propofol is safe if we carefully select and monitor the patient. 相似文献
