Psammomatoid ossifying fibroma (POF), a variant of ossifying fibroma, is a benign fibroosseous lesion typically arising within the nasal cavity, paranasal sinuses, and orbit. Cranial vault involvement is exceedingly rare, with very few cases reported in the literature. The authors report a case of POF in the neurocranium of an 11-year-old child, 4 years after chemotherapy and radiation therapy for acute lymphoblastic leukemia. This case is reported in view of its rarity, novelty of presentation, and the difficulty in diagnosis due to its radiological resemblance to aneurysmal bone cyst or monostotic cystic fibrous dysplasia, further aggravated by the clinical scenario. A novel technique of cranial reconstruction called autologous particulate exchange cranioplasty was used following tumor excision.

T-acute lymphoblastic leukemia/lymphoblastic lymphoma (T-ALL/LBL) is rare and aggressive leukemia. Philadelphia chromosome positive (Ph+) is the most common cytogenetic abnormality in chronic myeloid leukemia (CML) and B-acute lymphoblastic leukemia (B-ALL). Ph+ T-ALL is exceeding rare and has a therapeutic and prognostic significance. The incidence and outcome of Ph+ T-ALL are unknown. Differentiation between Ph+ T-ALL/LBL and T-cell lymphoblastic crises of CML may be difficult. We report a rare case of adult de novo T-ALL with significant monocytosis, having Ph+ with (P190 <i>BCR-ABL1</i>) as a cytogenetic abnormality. He was treated with ALL induction chemotherapy and imatinib and achieved complete remission, then relapsed twice and expired shortly after the last CNS relapse.
