An 18-year-old boy presented to our hospital with stridor. He had inability to close both eyes for 15 days. Examination showed bilaterally tonsillomegaly and a nasopharyngeal mass (NPM) extending into oropharynx causing the airway compromise [Figure 1]a. Bilateral Bell's phenomenon was observed. An emergency tracheostomy was performed. Blood investigations were: hemoglobin 150 g/L, white cell count 7 × 109/L, and platelets 238 × 109/L. computerised tomography (CT) scan of the neck revealed a large (69 × 40 × 92 mm) heterogeneously enhancing mass lesion involving the nasopharynx and extending down upto the oropharynx causing the airway compromise [Figure 1]b. The lesion was 18FDG-avid on positron emission tomography-computerised tomography (PET-CT) scan with areas of necrosis [Figure 1]c. No mediastinal mass was discerned on PET-CT scan [Figure 1]b. Biopsy of the NPM revealed sheets of medium-sized lymphoid cells with blastic nuclear chromatin. Immunohistochemistry showed diffuse immunoreactivity for CD3 (membranous) and TdT in the neoplastic cells, and negativity for CD56, CD16, and in-situ-hybridization-Epstein Barr virus early RNA (EBER ISH), consistent with the diagnosis of T-lymphoblastic lymphoma (LBL) [Figure 1]d,[Figure 1]e,[Figure 1]f. Bone marrow aspiration showed 40% blasts, immunoreactive for CD2, CD3, CD4, CD5, CD7, CD8, TdT, CD38, HLA-DR, and TCR-α/β, and negative for CD1a. Cerebrospinal fluid analysis revealed malignant cells. A diagnosis of T-LBL/leukemia with central nervous system (CNS) involvement was made. Treatment with BFM-95 protocol resulted in complete remission of T-LBL/leukemia, and patient is currently in maintenance phase. Among lymphoma involving the nasopharynx, diffuse large B-cell lymphoma is the commonest subtype (70–80%), followed by T-cell lymphoma, especially extranodal NK/T-cell lymphoma, nasal type. T-LBL accounts for only 2.4–7% of all nasopharyngeal lymphoma cases., T-LBL/leukemia is an aggressive neoplasm of T-lymphoblasts encountered most frequently in adolescent and young adults. Large mediastinal mass with/without superior vena cava syndrome is the commonest clinical presentation. CNS involvement at presentation is rare (3–9%). Extranodal presentation of T-LBL/leukemia without a concomitant mediastinal mass is uncommon. Pediatric acute lymphoblastic leukemia-based treatments impart an excellent prognosis.
