- Angioedema recorrente – caso clínicoPublication . Martins, Sandrina; Salgado, Miguel; Raposo, Filipa; Pinto, Diana; Martinho, Isabel; Araújo, RitaIntroduction: Hereditary angioedema (HA) is a rare cause of recurrent angioedema caused by a default in the gene that encodes the C1 esterase inhibitor (C1-INH). The oedema involves predominantly the face, limbs and genital and gastrointestinal tract. The involvement of the larynx, although less frequent, is the most severe clinical expression of HA and is potentially fatal. Case report: Clinical report of an eight-year-old female with multiple episodes of angioedema. The laboratory study confirmed the diagnosis of HA. Discussion: HA diagnosis is established based on the clinical history, family history and complements testing. Its documentation is extremely important because it is potentially fatal and needs specific therapy.
- Castleman disease. A rare diagnosis in childhoodPublication . Monteiro-Cunha, Sara; Vasconcelos, Sofia; Neto, Cláudia; Oliva, Tereza; Salgado, MiguelIntroduction: Castleman Disease (CD) is a rare polyclonal lymphoproliferative disorder characterized by massive growth of lymphoid tissue. The most common sites of disease are the chest, abdomen, neck, and axilla. Excisional biopsy is mandatory for diagnosis, and complete surgical resection the gold-standard treatment in unicentric CD. Case report: A ten-year-old girl was observed at the Emergency Department with sore throat and fever. Oropharynx examination revealed inflamed tonsils, with no exudates. Enlarged lymphadenopathy was palpable in the right supraclavicular fossa. Ultrasound revealed right supraclavicular lymphadenopathy with loss of adipose hilum and histopathologic assessment established CD diagnosis. Discussion/Conclusion: Lymphadenopathy is a common presentation in children, usually benign and self-limited. But it may also be a sign of underlying malignancy. Any lymphadenopathy in the supraclavicular fossa is worrisome and requires prompt investigation. CD diagnosis may be challenging, due its rare nature in childhood and nonspecific symptoms.
