1/3. Pyodermatitis-pyostomatitis vegetans: report of a case and review of the literature.Pyodermatitis-pyostomatitis vegetans is a benign, rare disorder characterized by a pustular eruption in the oral mucosa and vegetating plaques involving the groin and axillary folds. Its association with inflammatory bowel disease is well established. We report the case of a 49-year-old-white man with ulcerative colitis who manifested a vegetating, annular plaque in the left inguinal region of 2 months' duration. Oral examination disclosed an erythematous mucosa with multiple painful pustules involving the labial and gingival mucosa. Histopathologic study demonstrated epidermal hyperplasia and an inflammatory infiltrate composed mostly of neutrophils and eosinophils, grouped into microabscesses within the epidermis and with a bandlike configuration in the upper dermis. Results of direct and indirect immunofluorescence studies were negative. We discuss the differential diagnosis between pyodermatitis-pyostomatitis vegetans and pemphigus vegetans.- - - - - - - - - - ranking = 1keywords = hyperplasia (Clic here for more details about this article) |
2/3. cyclosporine A-induced gingival hyperplasia pemphigus vulgaris: literature review and report of a case.gingival hyperplasia appears in 8% to 85% of patients treated with cyclosporine. Most studies show an association between oral hygiene status and the prevalence and severity of this gingival overgrowth. Thus, besides attempting to substitute this drug with another whenever possible, treatment usually involves maintenance of strict oral hygiene coupled with scaling and root planing and removal of iatrogenic factors. Sometimes a second treatment phase involving periodontal surgery is necessary. cyclosporine-induced gingival overgrowth has been mainly described in post-organ transplant patients. The present case describes, for the first time, a severe form of cyclosporine-induced gingival overgrowth arising in a 15 year-old male with pemphigus vulgaris. Periodontal treatment included oral hygiene and scaling and root planing under local anesthesia. There was a significant reduction in gingival enlargement, as well as a reduction in plaque levels and inflammation. Cessation of drug administration, combined with continuous periodontal treatment, brought further improvement. This successful conservative treatment of cyclosporine-induced gingival overgrowth in a pemphigus vulgaris patient suggests that early diagnosis and comprehensive treatment of these lesions may yield good response and reduce the need for periodontal surgery.- - - - - - - - - - ranking = 5keywords = hyperplasia (Clic here for more details about this article) |
3/3. A rare association: Castleman's disease and pemphigus vulgaris.Castleman disease is a reactive lymph node hyperplasia of unknown origin that often involving the thorax although it may involve all parts of the body. It is usually seen in young adults and presents an asymptomatic course. It is usually located to anterior and middle mediastinum. pemphigus vulgaris is a bullous skin disease in which immune mechanisms take place in the pathogenesis. mouth and oropharynx are the most commonly involved structures. IgG antibodies against the epidermal intracellular structures are essential in the diagnosis. We have wanted to discuss a 28 years old female with the literature review since the association between pemphigus vulgaris and Castleman's disease is rare.- - - - - - - - - - ranking = 1keywords = hyperplasia (Clic here for more details about this article) |
