Retiform hemangioendothelioma (RH) is a rare intermediate (locally aggressive) vascular tumor that mostly affects the dermis of the trunk and limbs, but has never been reported in the inferior turbinate. A 10-year-old Chinese boy presented with recurrent epistaxis in his left nasal cavity and anemia for more than 2 years. Radiographic and electronic video laryngoscopic images showed an expansile mass in the left inferior turbinate. Endoscopic surgery and electrocautery were performed to resect the tumor beyond the macroscopic border. Histopathologically, the tissues were infiltrated by hyperplastic blood vessels arranged in a retiform pattern, and endothelial cells proliferate significantly in some areas. Immunohistochemistry showed a positive result for CD31, CD34, Fli-1, and ERG. No epistaxis, tumor recurrence, or metastasis was found on reexamination over 18 months after surgery.

Alveolar rhabdomyosarcoma (aRMS) is a rare pediatric malignant tumor with a poor prognosis, particularly when located in the rhinopharynx and sphenoidal floor, which complicates diagnosis and increases the risk of misclassification as benign growths. The specific genotype of aRMS is associated with a worse clinical outcome. In young children, especially those aged 4 to 12 years, rhinopharyngeal masses are often attributed to chronic adenoiditis; however, other benign (e.

Background: There is no consensus regarding the optimal regimen for metastatic nasopharyngeal carcinoma (dmNPC). Locoregional intensity modulated radiotherapy (LRRT) following palliative chemotherapy (PCT) has been shown to prolong the overall survival (OS) and improve the progression-free survival (PFS) of patients with dmNPC, compared with PCT alone. However, patients with a high tumor burden do not benefit from additional LRRT, which inevitably results in toxicity.

Hereditary haemorrhagic telangiectasia (HHT) is a vascular dysplasia inherited as an autosomal dominant trait and caused by loss-of-function pathogenic variants in genes encoding proteins of the BMP signalling pathway. Up to 90% of disease-causal variants are observed in ENG and ACVRL1, with SMAD4 and GDF2 less frequently responsible for HHT. In adults, the most frequent HHT manifestations relate to iron deficiency and anaemia owing to recurrent epistaxis (nosebleeds) or bleeding from gastrointestinal telangiectases.

Immune thrombocytopenic purpura (ITP) is an autoimmune condition characterized by a reduced platelet count due to enhanced peripheral destruction and impaired platelet production. While thrombocytopenia is a well-documented complication of various viral infections, cytomegalovirus (CMV), a member of the Herpesviridae family, is primarily associated with infections in immunocompromised patients and is rarely implicated in causing severe thrombocytopenia in immunocompetent patients. This article aims to highlight the importance of considering CMV as a significant etiological factor in ITP, particularly in cases of asymptomatic thrombocytopenia.

Granulomatosis with polyangiitis (GPA) is a subtype of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) that commonly requires aggressive immunosuppression to achieve remission. We present a case of a young Malay lady with recurrent episodes of ANCA-positive nodular anterior scleritis who responded poorly to topical and systemic corticosteroids and relapsed while on methotrexate. A year later, she had epistaxis, and a sino-nasal biopsy confirmed granulomatous vasculitis.
