1/7. Angio-immunoblastic lymphadenitis: remarks about two cases.Two patients with clinical and pathological symptoms of so-called angioimmunoblastic lymphadenitis are presented. Both patients were over 50, with multiple lymphadenopathies, fever, pruritus and hyperglobulinemia. The lymph node changes exhibited a characteristic histological triad consisting of diffuse lymphoid proliferation, small arborizing vessels proliferation and paraamyloid-like amorphous material deposition. As previous authors suggested, the disease seems to be the expression of a prolonged hyperimmune response induced by the hypersensitivity to certain factors.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/7. Recognition of retropharyngeal abscess in children.retropharyngeal abscess is a rare deep-neck infection that usually affects young children. Swelling in the neck can lead to sudden and fatal airway obstruction. Enlargement of lymph nodes located between the posterior pharyngeal wall and the prevertebral fascia occurs secondary to infection of the nasopharynx, paranasal sinuses or middle ear. Penetrating trauma or foreign-body penetration may also lead to abscess formation. Common symptoms include fever, swollen neck, difficult swallowing, muffled voice and hyperextension of the head and neck. Lateral neck radiographs confirm the diagnosis. Early surgical treatment prevents serious complications, such as mediastinal spread, aspiration of pus, airway obstruction or erosion into a major vessel.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/7. Subacute necrotizing lymphadenitis.We report the skin manifestations and abnormalities of subacute necrotizing lymphadenitis. As far as we are aware, this is the first report of this disease in the dermatology literature. The main features of subacute necrotizing lymphadenitis are fever, a cervical lymphadenopathy, and, occasionally, a skin eruption resembling urticaria, rubella, or a drug-induced erythema. A skin biopsy specimen showed a mild lymphohistiocytic perivascular infiltrate of cells in the papillary and mid dermis and deposition of fibrinogen around the capillary vessels. Subacute necrotizing lymphadenitis responds to oral corticosteroid therapy but not to antibiotics.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/7. Rhino-orbital zygomycosis.A 63-year-old diabetic man presented with sinusitis with orbital and intracranial signs progressing over one week, due to zygomycosis. Despite control of the diabetes, surgical excision of infected tissue and antifungal therapy he died in the fifth week of illness. Pathological study showed extensive fungal infiltration of periorbital structures and mycotic thrombosis of many blood vessels with associated necrosis and infarction of fat and extraocular muscles.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/7. Remote salmonellosis: surgical masquerader.The salmonella group of bacteria consists of at least 1700 subtypes and causes widespread gastroenteric disease throughout the world, there being approximately two million cases yearly in the united states alone. An uncommon but interesting complication is the hematogenous lodgment of organisms in other sites of the body with resultant localized abscess formation, often months or years later. We present a review of 15 cases seen in our affiliated hospitals over a nine-year period. Remote salmonellosis most often occurs in patients with underlying systemic disease, such as lupus, malignancy, diabetes, and sickle cell disease, or in association with therapy that suppresses host resistance including steroids and cancer chemotherapy. The most frequent sites of involvement are bone marrow, joints, meninges, pleura, and blood vessels, or in an area of locus minoris resistentiae. The latter include scars, hematomas, fracture sites, prosthetic devices, and neoplasms. Our experience would suggest that these infections, which can remote both in location and time from the original gastrointestinal episode, are perhaps more frequent today than is generally realized. diagnosis is often delayed because of lack of familiarity with this entity. Treatment consist of either drainage or excision of infected tissue often combined with long-term antibiotics.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/7. Inflammatory pseudotumor of pelvic lymph nodes.Inflammatory pseudotumor of lymph nodes (IPT) is a rare, recently described benign cause of lymphadenopathy. The IPT is composed of a proliferation of spindle cells, small vessels and inflammatory cells without atypia and formed by high and poor cellular areas. This study reports a case of IPT. It was a 50-years-old man in whom the abdominal mass was an incidental finding during exploratory laparatomy. The mass was a lymphadenopathy measuring 12 x 10 x 5 cm in diameters. Histologic examination revealed IPT of the lymph nodes. The patient has remained asymptomatic for more than 10 months following surgery without any treatment. In conclusion, IPT of the lymph nodes is being recognized increasingly and should be considered in the differential diagnosis of lymphadenopathies. Inflammatory pseudotumor (IPT) of the lymph nodes resembling the IPT of other organs was recently described as a possible cause of lymphadenopathy. Histologically, the process showed a proliferation of spindle cells associated with a mixture of polymorphic inflammatory cells and small blood vessels involving the connective tissue framework (hilum, trabecula, capsule) of the lymph node. In this report, the case of a patient with IPT of pelvic lymph nodes is presented with the clinical and pathological features.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
7/7. Skin involvement in Kikuchi's disease: an immunocytochemical and immunofluorescence study.Kikuchi's disease (KD) is a benign self-limiting febrile illness usually affecting young women, which is manifested clinically by fever and cervical lymphadenopathy. Skin involvement in KD is very rare and is evident clinically in the form of skin rashes and nodules. We describe one such case of KD in a 33-year-old Bulgarian woman who presented with cervical and axillary lymphadenopathy and who developed a transient facial rash. biopsy of axillary lymph nodes showed the characteristic features of KD with infiltration of the lymph node paracortex by apoptotic plasmacytoid monocytes. Biopsies of the facial skin showed two features: (1) dermal infiltration by apoptotic plasmacytoid monocytes; (2) on immunofluorescence studies of frozen sections prepared from involved and uninvolved facial skin, deposition of immunoglobulins and complement at the dermoepidermal junction and in the walls of dermal blood vessels. Such immunofluorescence findings in the skin of patients with KD have never been described. These findings suggest the presence of an autoimmune reaction as a component of KD.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
