- 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.
- Rhino-orbital-cerebral mucormycosis in a pediatric cancer patientPublication . Couto, Maria Eduarda; Oliva, Tereza; Alberto, Pedro; Lebre, Ana; Pinto, Armando; Ferreira, Ana MaiaAim: Mucormycosis infections are highly lethal in immunosuppressed patients. The authors present a rare case of successful treatment of the condition. Case description: A 14-year-old male with acute lymphoblastic lymphoma in remission was diagnosed with pansinusitis, cerebral osteomyelitis, and encephalitis with an abscess caused by Rhizopus sp. Neurosurgical drainage, endoscopic sinus surgery, and left eye enucleation were performed, and the patient was simultaneously treated with lipossomal-amphotericin B and posaconazol (later replaced by isavuconazol). However, complications (left frontal lobe herniation and cerebrospinal fluid fistula) ensued, requiring surgical reoperation. Chemotherapy was restarted four months later. Comments: This is a rare case report, in which early and aggressive surgery, antifungal treatment, and multidisciplinary team work were crucial for the successful outcome.
