HUMANS CHILD LYMPHATIC DISEASES

This paper illustrates the spectrum of CT findigns of pulmonary tuberculosis in children and shows the advantages and complementary nature of CT compared with conventional radiography. Common CT manifestations of pulmonary tuberculosis in children are mediastinal or hilar lymphadenopathy, air-space consolidation, atelectasis and disseminated nodules. CT is useful in the detection of the disease in equivocal chest radiographs, in the characterization of lesions, by demonstrating caseation necrotic areas, calcification and bronchogenic spread nodules, and in defining the extent of the disease and its complications. This in formation will be helpful in the diagnosis and evaluation of tuberculosis in children.

Rosai-Dorfman disease also known as sinus histiocytosis with massive lymphadenopathy is a benign, rare systemic disease characterized by a histiocyte proliferation which presents with lymphadenopathy. We report a case of a 4-year-old girl who presented with recurrent cervical lymphadenopathy with tenderness, without any other symptoms. After 1 month of medical treatment, her lymphadenopathy still remained, so we performed complete excision and biopsy. She was diagnosed on cytology as a case of Rosai-Dorfman disease. She responded well to become asymptomatic without recurrence by 1 month.

Gianotti-Crosti syndrome (GCS) is a sporadic dermatosis affecting mainly children. It is characterized by multiple, confluent, monomorphic and pruritic pink to red-brown papules or papulovesicles, distributed symmetrically on the face, extensor surfaces of the extremities and buttocks, commonly sparing the trunk, palms and soles. This can be preceded by a viral infection, and may be accompanied by fever, hepatosplenomegaly, or lymphadenopathy. Personal and family history of atopy appears to be a risk factor in the subsequent development of GCS, thus frequently diagnosed as atopic dermatitis. We report a case of a 4-year-old boy from our institution with generalized, pruritic, papulovesicular rashes on the face and extremities for one month. He was diagnosed to have atopic dermatitis and treated as such, before presentation to our institution. As the signs and symptoms in GCS are similar to atopic dermatitis, we suggest that this diagnosis be considered when presented with a similar case.

Leukemic reticuloendotheliosis (L.R.E.) was first described as a clinical and pathological entity by Ewald in 1923. LRE is a rare neoplastic disease of the hematopoietic system that is characterized cliniclly by chronic course with an insidious onset. marked splenomegaly with absence of substantial lymphadenopathy and predominant in male and characterized histologically by the presence of circulating abnormal mononuclear cells with many cytoplasmic projections, which have been refered to ??airy cells frequently. Splenectomy appeared to be the most beneficial treatment at present for those patients with massive splenomegaly and hypersplenism and chemotherapy is of little benefit in the treatment in LRE. Recently, the authors had the opportunity to observe a two year and eight old male child at this hospital whose clinical course and pathologid features were consistent with LRE. Splenectomy is performed and discharged with relatively good conditions.

PURPOSE: We evaluated Kawasaki disease(KD) in children in order to evaluate the clinical characteristics and coronary complication of infantile Kawasaki disease. METHODS: A total of 226 medical records of children with KD admitted to The Catholic University of Korea, St. Mary's Hospital, from 1994 to 2003 were retrospectively analyzed. RESULTS: The incidence of lymphadenopathy was statistically lower in infantile Kawasaki disease than in Kawasaki disease of children older than one year. The incidence of atypical Kawasaki disease in infant(32%) was greater than that of total patients(24%), but there was no statistically significant difference in two groups. The incidence of coronary complication in atypical Kawasaki disease in children younger than one year was 50%(6/12), which was greater than that of coronary complication in typical KD of children older than one year. CONCLUSION: Diagnostic difficulties in infantile Kawasaki disease are due to high incidence of atypical characteristics of Kawasaki disease. Yet, early treatment with IVGV and aspirin is necessary because of its high incidence of coronary complication.

Kikuchi's disease(Histiocytic necrotizing lymphadenitis) is an idiopathic, self-limiting disease typically affecting cervical lymph nodes in young adults. Cutaneous involvement has been reported in 16-40%. We report a case of Kikuchi's disease in 10-year-old female that showed asymptomatic erythematous papules on the face accompanied by cervical lymphadenopathy. The histopathologic examination of the skin revealed diffuse dermal lymphohistiocytic infiltrate, a large amount of nuclear dust with absence of neutrophils, which is characteristic of Kikuchi's disease. In general, histopathologic findings of skin biopsy show a mirror image of that of lymph nodes involved in Kikuchi's disease. Therefore, it is important to recognize cutaneous manifestations of this entity, because we can avoid invasive lymph node biopsy. if skin lesions involved show typical histopathologic findings of Kikuchi's disease.

Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) now provides an important alternative diagnostic modality in patients with intrathoracic tuberculosis lymphadenopathy. The procedure is well tolerated in the outpatient setting, provides access to the mediastinal and hilar lymph node locations commonly in tuberculosis and also allows bronchial washing to be performed at the same procedure. However, there is no report of EBUS-TBNA applied to children to diagnose tuberculosis. We report a case of EBUS-TBNA applied to children who had intrathoracic tuberculosis lymphadenopathy.

Lymph node enlargement is a common finding in children suggesting normal or benign. Palpable nodes which are large, hard or fixed must be examined carefully to rule out malignant diseases. In this case, a 15-year-old boy presented to our hospital to inspect the palpable mass at his post-auricular area being found 2 months ago. It was diagnosed as nodal marginal zone lymphoma (NMZL) through excisional biopsy and immunohistochemistry. NMZL is very rare, especially in children and young adults, but occurs locally in most cases with a good prognosis compared to adults. We described a rare case of NMZL diagnosed in adolescent.
