1/12. Bacillary angiomatosis affecting the oral cavity. Report of two cases and review.Bacillary angiomatosis (BA) is an infectious disease characterized by proliferative vascular lesions; it mainly affects hiv-positive patients. Multiple cutaneous nodular lesions together with fever, chills, malaise, anorexia, vomiting and headache are the most important clinical manifestations. It may also involve the heart, liver, spleen, bones, lung, muscles, lymph nodes, central nervous system and other organs. erythromycin, 500 mg four times a day, is the drug of choice. The importance of this lesion lies in its clinical and histological similarity with other diseases. Cutaneous and oral lesions of BA clinically resemble Kaposi's sarcoma (KS). Histopathologically, BA may be confused with angiosarcoma, pyogenic granuloma and epithelioid hemangioma. We report two hiv-positive men with BA lesions in the oral mucosa. diagnosis was confirmed by biopsy and Warthin-Starry silver staining.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
2/12. Bacillary angiomatosis of the scalp in a human immunodeficiency virus-negative patient.Bacillary angiomatosis (BA) is a recently recognized bacterial infectious disease that is mainly seen in patients with the acquired immunodeficiency syndrome. BA has rarely been reported in immunocompetent individuals. A case of BA of the scalp in an immunocompetent patient, who was human immunodeficiency virus seronegative, is reported. The importance of differential diagnosis of this lesion is emphasized.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
3/12. Bacillary angiomatosis in a child undergoing chemotherapy.Bacillary angiomatosis is an infectious disease of the skin and viscera characterized by vascular lesions, originally described in patients with human immunodeficiency virus infection. There are also case reports of bacillary angiomatosis occurring in immunocompetent patients and in noninfected patients with suppressed immune function. We report a case of bacillary angiomatosis in a child undergoing chemotherapy for acute leukemia.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
4/12. Bacillary angiomatosis in an immunocompetent child with a grafted traumatic wound.Bacillary angiomatosis is an infectious disease which usually develops in immunocompromised patients. Contact with cats is implicated in its pathogenesis. We report a seven-year-old immunocompetent boy with bacillary angiomatosis without a history of direct contact with cats. The clinical diagnosis of bacillary angiomatosis was made following histopathological examination of a biopsy sample from the infected facial wound, in the vicinity of which angiomatous lesions had developed. Surprisingly, similar lesions also appeared at the donor site of the skin graft which was grafted on the facial wound. This case demonstrates that bacillary angiomatosis may also be seen in immunocompetent patients and that it may contaminate wounds without the intermediary of cats.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
5/12. bartonella quintana coinfection with mycobacterium avium complex and CMV in an AIDS patient: case presentation.BACKGROUND: As a greater number of hiv-infected patients survive despite profound immunodepression due to medical progress, we face complex infection with multiple agents in AIDS-patients. CASE PRESENTATION: We report the case of an AIDS patient with a primary clinical presentation suggestive of bacillary angiomatosis. We also found in cutaneous lesions mycobacterium avium complex and cytomegalovirus. CONCLUSION: This clinical case illustrates the possibility of multiple coinfections in AIDS patients and the need to be exhaustive in evaluating infectious diseases in severely immunocompromised patients.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
6/12. Clinical, histologic, microbiologic, and biochemical characterization of the causative agent of bacillary (epithelioid) angiomatosis: a rickettsial illness with features of bartonellosis.It has been suggested that bacillary (epithelioid) angiomatosis (BEA) is a manifestation of cat scratch disease (CSD). Because of clinical similarity between this condition and the verruga peruana phase of bartonellosis, we sought to further characterize this disease as well as its causative agent and to compare it to bartonellosis. We isolated a small flagellated pleomorphic bacillus from skin lesions of two patients with BEA. Organisms were stained successfully with Warthin-Starry silver stains, but immunohistochemistry failed to demonstrate binding with a polyclonal antibody directed against the cat scratch bacillus. Whole cell fatty-acid gas chromatography performed on both BEA organisms and bartonella bacilliformis demonstrated marked similarity between the two. Electron microscopy of BEA organisms in tissue and in suspension revealed features characteristic of a gram negative bacillus. Based on these findings, we propose that this unusual rickettsial infectious disease with vascular proliferation may represent an unusual variant of infection with a bartonella-like organism rather than a manifestation of cat scratch disease.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
7/12. Case report 860: Bacillary angiomatosis of the calcaneum.Bacillary angiomatosis (BA) is newly reported infectious disease observed mainly in hiv-infected patients, caused by a small gram-negative bacillus of the Rochalimea genus. From a purely dermatological presentation similar to that of Kaposi's sarcoma, it may evolve into a systemic disease. Bone lesions seem fairly frequent. We report a case of an isolated osteolytic lesion due to the BA bacillus.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
8/12. Bacillary angiomatosis in a German patient with AIDS.A 52-year old male homosexual patient with acquired immunodeficiency syndrome (AIDS) presented in our clinic with multiple nodular papules (more than 100) spread over the whole body which had developed within 3 months. Bacillary angiomatosis was suspected, which is a bacterial infectious disease recognized recently mainly in patients with AIDS. Histological and immunohistochemical examinations of extirpated skin lesions were in agreement with the diagnosis, and the detection of rod-shaped bacteria in the lesions by Warthin-Starry silver stain confirmed it. The patient was treated with 2 x 100 mg doxycycline per day. The fever disappeared, and the cutaneous lesions showed a slight tendency to improve. However, after 5 days of therapy the patient showed increasing weakness, with muscle and bone pain. The patient died 10 days after the doxycycline therapy had been started. The cutaneous lesions in bacillary angiomatosis may resemble Kaposi's sarcoma and may therefore be misdiagnosed. The disease may be fatal, but timely antibiotic treatment is usually effective; therefore, the diagnosis of bacillary angiomatosis is important. Although many cases have been reported from the united states, only one case is known from europe. Our finding of bacillary angiomatosis in a German AIDS patient supports the concept of a worldwide distribution of this bacterial agent.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
9/12. Case report: bacillary angiomatosis with massive visceral lymphadenopathy.Bacillary angiomatosis is a newly characterized infectious disease occurring mainly in patients with AIDS. Most patients have cutaneous angiomatosis lesions resembling Kaposi's sarcoma or pyogenic granuloma. Although the disease may be life-threatening if not treated, it is curable with appropriate antibiotic therapy. A patient had a fever, nightsweats, abdominal pain, pleural effusions, and asymmetric peripheral lymphadenopathy. Computed tomography of the chest and abdomen revealed a unique pattern of enhancement of lymph nodes that, to this research team's knowledge, has not been reported previously with this condition. Appropriate antibiotic therapy resulted in a complete resolution of the disease. Included is a discussion of the clinical presentation, etiology, histology, and treatment of bacillary angiomatosis.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
10/12. Kaposi's sarcoma versus bacillary angiomatosis.persons with acquired immune deficiency syndrome (AIDS) are subject to a host of pathologic entities secondary to a depressed immune system. Kaposi's sarcoma frequently presents in this immunocompromised population and, therefore, diagnosis seems clinically straightforward. However, because of the prevalence of a strikingly similar infectious disease known as bacillary angiomatosis, skin biopsy of one or more lesions is crucial.- - - - - - - - - - ranking = 1keywords = infectious disease (Clic here for more details about this article) |
